Compression Springs

What expansion does a Compression Spring exhibit upon compression?

  • Compression springs expand when they are compressed
  • The enlargement of the outside diameter under load deltaDA in mm is calculated with block length LbI and free bearing of the spring ends:     deltaDa= 0.1*m²-0.8md-0.2d²/Dm 
  • m=Lo-d/if for springs with squared and ground ends and m=Lo-2.5d/if for springs with unsquared, unground ends
  • d = wire diameter [mm]
    Dm = average coil diameter [mm]
    Lo = length of unloaded spring [mm]
    if = number of spring coils
    Lbl = solid length [mm]
  • We offer as download a free calculation program for compression springs on our homepage, in which the expansion of the compression springs can be calculated

What surfaces are provided for Compression Springs?

  • Compression springs made of the material 1.1200 spring steel are oiled
  • Compression springs made of the material 1.4310 stainless steel are dry

What is the winding direction for Compression Springs?

  • The winding direction of the compression spring is right
  • If you look through the spring axis, the winding of a spring wound to the right moves away clockwise

What is the service life of Compression Springs for a force F1?

  • The actual service life of a compression spring depends, among other things, on the spring deflection between the two compression points and their position relative to the spring length
  • The service life differs for each spring
  • Our engineers are pleased to help you with the design and calculation of your application problem

What are the outside diameter tolerances and spring rate tolerances for Compression Springs?

  • Compression springs with designation 0D... all tolerances are according DIN 2076
  • Compression springs with designation 0C... tolerances are as follows:

What happens when a Compression Spring is set?

  • Compressing a compression spring for the first time in the direction of the later operating force is called setting when stresses above the yield point are generated which result in a favourable residual stress condition
  • After setting, residual stresses are present in the most heavily loaded edge zone of the spring which are favourably opposed to the operating stress

 

What is the spring rate or spring constant of a Compression Spring?

  • If the spring rate c [N/mm] is multiplied by the travel s [mm], the spring force F [N] is obtained
    F=c•s
  • “Spring rate” and “spring constant” are synonymous terms
  • As a rule, springs have a linear displacement-force ratio
  • There are exceptions for certain forms of springs such as conical springs, compression springs with different pitches, disc springs, e.g. slotted disc springs with a degressive/progressive displacement-force curve

Exception

  • Constant force springs have almost the same force over the travel
  • In the case of extension springs, the linear force-deflection curve can begin at a higher level due to the pretensioning produced during winding

What is the solid height of the Compression Spring?

  • If you compress compression springs so far that all coils are touching and no more force can be exerted by the spring the remaining length of the spring is referred to as the solid height
  • For Febrotec, this dimension is only a reference dimension; the number of coils can be varied in order to enable tolerance compensation with regard to spring forces in production

What is the maximum force that a Die Spring can achieve?

  • Die springs are designed for situations where considerable loads are applied in a very confined space, particularly in the case of press dies
  • The use of chromium-vanadium/CrSi steels in accordance with SAE 6150 permits maximum loads to be combined with a long service life
  • Die springs are classified in groups according to diameter. However, with this system, die springs with the same mounting dimensions can be selected in accordance with different load requirements
  • This increases the durability of stamping, bending and other dies
  • Each group of die springs is arranged according to a color code system, in order of increasing load. Die springs in accordance with the ISO 10243 standard
  • The solid length is approx. Ln; here the maximum forces are achieved
  • For frequencies greater than 1000 strokes/minute, the following values should be observed in the case of springs with the designation 0R....
    Green: 25% to 30% compression
    Blue: 20% to 25% compression
    Red: 15% to 20% compression
    Yellow: max. 15% compression

Springs with the designation 0ST... have the following color codes and load types

  • Medium loads = Blue
    Medium heavy loads = Red
    Heavy loads = Gold
    Extra heavy loads = Green

What material are Die Springs made of?

  • Die springs are manufactured from hardenable chromium-silicon steels

What is the difference between Raymond and ISO Die Springs and what are their colour codes?

  • Both types of indicated die springs are produced by Associated Spring Raymond with the highest quality standard
  • The ISO springs with the designation 0R... were defined subsequently by the ISO standardization organization and are intended for use with stamping and forming dies
  • Many dimensions of the two series of springs are absolutely identical in terms of external measurements; however, the series have different color coding systems
  • It should be kept in mind that the ISO has set such large tolerances that e.g. the rounding of the edges and the profile cross-sections can exhibit great variation with the resulting solid lengths
  • Our products traditionally have a demonstrably long service life, which is due to very good quality.

Conical Springs

Material for springs

 View PDF

  

How far can you compress a Conical Spring?

  • Conical springs are designed with a spring rate i.e. the pitch is variable
  • The solid height is much shorter than with compression springs
  • In the case of spring deflection, the length of the block is determined by  winding up to a maximum of 2 wire diameters
  • We can calculate conical springs for you; if you have special requests, please contact us

 

 

 

Why does the Conical Spring from Febrotec have a spring rate?

  • Each of our conical springs has a changing pitch which results in a longer part of the linear spring rate
  • Conventional conical springs usually have a constant pitch which results in a progressive spring rate

What material are Conical Springs made of?

  • Conical springs are made of material according to DIN 17224 - 1.4310 Stainless spring steel wire
  • An application up to 260° Celsius is possible

What is the end shape and spring coil direction of Conical Springs?

  • The ends of conical springs are laid out and not ground
  • The springs are right-hand coiled

Gas Struts

Where is the test force of a Gas Strut measured?

  • The test force for a gas strut is shown in the diagram at point P1
  • The piston rod is pressed in up to 5 mm before the end stop, then the strut is relieved up to 5mm before total deflection and at this point (P1) the test force is measured


Handkraft

Can Gas Struts be pressurized?

  • Yes, we can set the desired pressure in the cylinder ex-works
  • When selecting the cylinders in our shop, you may define the required pressure using a selection field
  • A gas strut with an individual force set once cannot be reset
  • For prototypes we have pressure-adjustable cylinders (V-series X-series) available where you can adjust the pressure yourself by means of a release valve. Dismantling the gas pressure strut for this is not necessary

 

How does a Gas Strut work?

  • A gas strut consists of a piston rod which moves in a closed cylinder under pressure. The piston rod has a piston at the end which prevents it from sliding out of the cylinder and which guides the piston rod. The force of the gas pressure spring is calculated from the cross-section of the piston rod times the pressure in the cylinder. The higher the gas pressure, the higher the force of the cylinder. Filling the gas strut with incombustible nitrogen has the advantage that the relatively large gas molecules can be better prevented from escaping from the cylinder by the seal.
  • Gas struts are most commonly used as a counterbalance for raising and lowering doors and hatches. Typical applications are vehicle tailgates and boot lids, luggage compartments, skylights and machine guards.
  • The tube containes a small amount of oil to lubricate the rod and to control damping at the end of the stroke. Gas struts should always be mounted with the rod downwards to prolong their service life.

 

What are the differences between Gas Struts, Gas Pressure Dampers and Nitrogen Cylinders in our Gas Strut series?

  • Ideal for prototyping new applications and those which cater for varying weights

 

* High tech sealing technology: >6mm rod diameter 2 cylinder sealings.

How do I mount a Gas Strut?

  • The piston rod of the gas strut should normally be at the bottom when at rest, as the oil present in the cylinder on the seal and the guide ensures a longer service life
  • The minimum angle to the horizontal should be 30° with the piston rod pointing downwards
  • This also applies to the storage of gas struts
  • On request, we are able to supply gas struts for series which allow horizontal installation of the gas strut due to special grease fillings
  •  Suitable for temperatures between -30°C to +80°C and have a different force depending on the temperature (gas expansion).
  • Radial forces (transverse to the piston rod) must be avoided
  • Do not lubricate the outer piston rod with grease or oil
  • Keep the piston rod free of dirt and dust
  • Do not use oils or solvents for cleaning
  • Only 90% of the complete stroke should be used in order not to continually move the quantities of grease and oil at the end of the stroke

 

 

What do I do if the Gas Strut has lost pressure?

  • If the nitrogen in the cylinder has completely or partially escaped through the seal between the piston rod and the seal, do not try to open the cylinder or fill it with gas - this is a very dangerous process due to the remaining high internal cylinderical pressure!
  • Please contact us in the event of a problem. We will help you to find a solution.
  • If there is no information regarding the force of the cylinder on your defective gas pressure strut please contact us. We have adjustable gas struts V-series in our program.

 

 

 

 

 

Would you like help from Febrotec for the design of Gas Struts for flaps or doors?

  • Our engineers would be pleased to advise you on the optimal use of gas struts
  • Using our calculation program we can design individual gas struts or a series of gas struts for you
  • With the hand force you require, even large constructions, such as window systems, ventilation grilles, solar systems, service flaps, machine hoods, vehicle boot lids, sales car shutters and folding beds can be optimally opened and closed in the motor home area

 

 

 

Can I return a supplied Gas Strut if the pressure is insufficient?

  • The pressure of every gas strut is individually adjusted in the cylinder according to the individual force selected by the customer
  • For this reason Febrotec cannot take back any cylinders

Safety data sheet and installation instructions for Gas Struts

 IMPORTANT SAFETY INFORMATION

  •  Please read these instructions carefully before you install this product
  • Incorrect installation may invalidate product warranty
  • Gas Struts (also known as Gas Springs)
  • Gas Springs contain Nitrogen gas at high pressure
  • Please dispose of used items carefully

 

Instructions for Installation

  • Gas struts should be mounted at an angle of 60° to the vertical with the piston rod down to ensure lubrication of the cylinder seals. The gas springs should be mounted without lateral forces. End fittings must be fully screwed into position on both ends prior to final location.
  • Gas struts contain nitrogen under high pressure. The cylinder should never be opened, punctured or exposed to high temperatures. Handle the piston rod with great care, as damage will result in consequential damage to the internal seals. The piston rod should not be scratched, soiled, painted, lubricated or bent. Damage to the piston rod will void the warranty
  • All gas struts have a seal between piston rod and cylinder. This seal is wetted with internal oil to ensure optimum functioning of the system. For this reason, gas struts should be installed with the piston rod pointing downwards.

  • Take great care when assembling and disassembling the gas pressure strut, as the pressure in the cylinder can generate dangerous forces.
  • Gas struts are not designed for transverse or lateral forces. If possible, use ball fasteners. To avoid bending the gas spring, the application should take the proportions of the cylinder into consideration.
  • Only 90% of the complete stroke should be used in order not to move the quantities of grease and oil at the end of the stroke again and again.
  • Ensure that the end fittings are fully fastened. If it is necessary to align the fastenings, the greatest care and attention should be taken.
  • Gas struts should not be used for more than 15 strokes/minute, otherwise disproportionately high heat generation due to friction will destroy the internal seals. We recommend using mechanical stops to limit the stroke of the cylinder.

 

Varilift® GAS StrutS

  • Varilift® gas struts contain nitrogen under high pressure. Never open, puncture or expose the cylinder to high temperatures. The Varilift® gas struts lose power in the long term. You should check periodically whether the desired function is still guaranteed. Otherwise, the gas pressure strut must be replaced.

 

INSTRUCTIONS to set the Varilift® VALVE

  • The Varilift gas strut® is fitted with a release valve (A) at the body end of the unit. This valve can be used to release gas from the unit to lower the force required to compress or extend it
  • Prior to attempting to perform this gas release, extreme care should be taken to prevent injury if too much gas is released
  • Where possible, it may be advantageous to increase the panel weight by 10% when performing this operation to prevent over release of the gas
  • To release gas from the unit use an allen key provided to unscrew the lock screw (B) at the side on the valve
  • Slowly unscrew the lock screw (anti-clockwise) until the gas can be heard escaping. Immediately re-lock the screw and try the unit
  • Extreme care should be taken during this operation as a small amount of discharge dramatically lowers the pressure of the unit
  • When using 2 struts on an application, adjust struts in sequence until the correct operation is achieved.

 Do not under any circumstances remove the adjustment screw from the valve.

 

What is the maximum permissible ambient temperature for Gas Struts?

  • The maximum permissible ambient temperature for gas struts is between -30°C and +80°C

What is the service life of Gas Struts?

  • The maximum service life of 30000 load cycles for the N and S series and is strongly dependent on environmental conditions such as dust and abrasive components of the ambient air
  • One can assume a power loss of approx. 10%

Safety Data Sheet and Installation Instructions for Gas Struts

  IMPORTANT SAFETY INFORMATION

  •  Please read these instructions carefully before you install this product
  • Incorrect installation may invalidate product warranty
  • Gas Struts (also known as Gas Springs)
  • Gas Springs contain Nitrogen gas at high pressure
  • Please dispose of used items carefully

 

Instructions for Installation

Gas struts should be mounted at an angle of 60° to the vertical with the piston rod down to ensure lubrication of the cylinder seals. The gas springs should be mounted without lateral forces. End fittings must be fully screwed into position on both ends prior to final location.

Gas struts contain nitrogen under high pressure. The cylinder should never be opened, punctured or exposed to high temperatures. Handle the piston rod with great care, as damage will result in consequential damage to the internal seals. The piston rod should not be scratched, soiled, painted, lubricated or bent. Damage to the piston rod will void the warranty

All gas struts have a seal between piston rod and cylinder. This seal is wetted with internal oil to ensure optimum functioning of the system. For this reason, gas struts should be installed with the piston rod pointing downwards.

Take great care when assembling and disassembling the gas pressure strut, as the pressure in the cylinder can generate dangerous forces.

Gas struts are not designed for transverse or lateral forces. If possible, use ball fasteners. To avoid bending the gas spring, the application should take the proportions of the cylinder into consideration.

Only 90% of the complete stroke should be used in order not to move the quantities of grease and oil at the end of the stroke again and again.

Ensure that the end fittings are fully fastened. If it is necessary to align the fastenings, the greatest care and attention should be taken.

Gas struts should not be used for more than 15 strokes/minute, otherwise disproportionately high heat generation due to friction will destroy the internal seals. We recommend using mechanical stops to limit the stroke of the cylinder.

 

Varilift® GAS StrutS

Varilift® gas struts contain nitrogen under high pressure. Never open, puncture or expose the cylinder to high temperatures. The Varilift® gas struts lose power in the long term. You should check periodically whether the desired function is still guaranteed. Otherwise, the gas pressure strut must be replaced.

 

INSTRUCTIONS to set the Varilift® VALVE

The Varilift gas strut® is fitted with a release valve (A) at the body end of the unit. This valve can be used to release gas from the unit to lower the force required to compress or extend it. Prior to attempting to perform this gas release, extreme care should be taken to prevent injury if too much gas is released. Where possible, it may be advantageous to increase the panel weight by 10% when performing this operation to prevent over release of the gas. To release gas from the unit use an allen key provided to unscrew the lock screw (B) at the side on the valve. Slowly unscrew the lock screw (anti-clockwise) until the gas can be heard escaping. Immediately re-lock the screw and try the unit. Extreme care should be taken during this operation as a small amount of discharge dramatically lowers the pressure of the unit. When using 2 struts on an application, adjust struts in sequence until the correct operation is achieved.

 Do not under any circumstances remove the adjustment screw from the valve.

Can Gas Struts be pressurized?

  • Yes, we can set the desired pressure in the cylinder ex-works
  • When selecting the cylinders in our shop, you may define the required pressure using a selection field
  • A gas strut with an individual force set once cannot be reset
  • For prototypes we have pressure-adjustable cylinders (V-series X-series) available, which you can adjust the pressure yourself by means of a release valve. Dismantling the gas pressure strut for this is not necessary

Which surfaces do Disc Springs in accordance with DIN 2093 have?

  • All disc springs made from carbon steels and CrV steels are phosphated and oiled

What has to be taken into account when stacking Disc Springs?

The best disc spring arrangement is that which uses the smallest possible number of disc springs.

The friction increases as the number of disc springs in the stack increases. Therefore, in the case of multiple layers for dynamic operation, no more than 2 to 3 springs should be used in parallel.

As a guide value for stack length=Lo we recommend:

  • Lo<=3*Da where the outside diameter=Da. If a greater length cannot be avoided, the stacks should be subdivided by rigid intermediate washers
  • Guidance of the disc springs should take place on the inside or the outside; the hardness of the guide mechanism, at 55 to 56 HRC, should exceed that of the disc springs

  • The dimensions are determined in inches

What type of lubrication should be provided for Disc Springs?

  • The lower the friction, the lower the wear between the disc springs and adjacent components
  • Oil, grease, paste with molybdenum disulfite or other solid lubricants reduce the friction coefficient

What corrosion protection do Disc Springs have?

  • The disc springs we offer are made of carbon steel and have a protective layer of zinc phosphate
  • A corrosion protection oil is stored in this zinc phosphate layer
  • Stainless steel disk springs have no additional surface protection against corrosion

With what torque are nuts for Disc Springs tightened?

If a disc spring is preloaded by means of a threaded connection (e.g. for temperature compensation), how is the torque calculated for loading the disc spring?

  • The formula is: F1*Pi*2*l/P=F2
  • F1 = force on lever arm in N
    Pi = 3.14
    l = length of lever arm in mm
    P = thread pitch in mm
    F2 = force in axial direction (i.e. in the direction of the load on the disc spring) in N
    MD = torque in Nmm
  • or F1*l=F2*P/Pi*2
  • or Md=F2*P/Pi*2
  • When putting the torque into the screw-thread-system the friction factor has to be taken into consideration.

  • single fold layering --> +-2...3%
  • 2-fold parallel layering --> +-4...6%
  • 3-fold parallel layering--> +-6...9%
  • 4-fold parallel layering --> +-8...12%
  • 5-fold parallel layering -->+-10-15%

Disc Springs for Ball Bearings

What is the Ball Bearing Disc Spring, unslotted, used for?

  • Unslotted disc springs for ball bearings provide axial preloading of deep groove ball bearings, and can compensate for differences caused by dimension deviations
  • In dynamic loading the disc springs absorb vibrations generated by the deep groove ball bearings, and also result in noise reduction and extended durability of the deep groove ball bearings

What is the deflection of Ball Bearing Disc Springs?

  • Due to their design, disc springs for ball bearings, not slotted, can be deflected up to the flat position, and no setting is to be expected

What has to be considered for the layering of Ball Bearing Disc Springs, not slotted?

  • Disc springs for ball bearings, not slotted, have a pronounced degressive spring characteristic curve
  • Therefore, it is not recommended to use alternately layered disc spring columns
  • In order to achieve higher forces, however, these disc springs can be stacked in the same direction; the friction effect between compression and compression (hysteresis) should be taken into account

What is tempering?

Tempering

  • Compression and extension springs are tempered in order to reduce the stresses indicated in the manufacture of the springs
  • This prevents an uncontrolled loss of force in the operation of compression springs and prevents possible loop failure in extension springs
  • For torsion springs, tempering is not absolutely necessary when loads are applied in the direction of rotation, which in any case is the only direction permitted according to technological principles

The following are standard values for tempering temperatures:

Stainless Steel 1.4568 

  • 400 °C 1,0 hours

Copper Beryllium 1.1266

  • 310 bis 320°C -  2 hours  

              
Inconel 2.4669 

  • dependent on service temperature and basic hardness of wire

Approximate time for tempering

  • d~1mm        > 5 minutes
  • d~10-15 mm  10-25 minutes
  • d~20mm      >30 minutes

What is shot peening?

  • Shot peening is the cold working and polishing of the spring surface by bombardment with spherical shot or glass beads
  • The polishing retards possible crack formation
  • Shot peening increases durability by approximately 30%
  • For stainless spring steels, glass beads are used; for other spring steels, rounded wire shot from 0.6 mm to 0.9 mm is used, depending upon the diameter of the spring wire

What does “shear stress” mean?

  • "Shear stress" means that when a load is applied to springs, eccentric stresses (relative to the wire cross-section) occur

What is the tensile strength of Spring Wire?

The tensile strength [N/mm²] is listed in combination with the wire diameter.

What is the fatigue limit?

Material fatigue test

  • Similar springs are subjected to cyclical stresses of decreasing magnitude
  • Each spring failure is plotted as a point on the curve, according to the number of cycles to failure
  • Springs that withstand the stresses for more than 10 million cycles are considered to be durable
  • The almost horizontal part of the curve defines the fatigue limit of the spring

What is fatigue failure and what is a Wöhler curve?

Material fatigue test

  • Similar springs are subjected to cyclical stresses of decreasing magnitude
  • Each spring failure is plotted as a point on the curve, according to the number of cycles to failure
  • Springs that withstand the stresses for more than 10 million cycles are considered to be durable
  • The almost horizontal part of the curve defines the fatigue limit of the spring

What is the strength of Spring Steels?

What is the elastic limit?

  • The maximum stress that a material can withstand without permanent deformation is referred to as the “elastic limit”
  • The yield point (Re) and the technical yield strength (Rp 0.2) are used as the basis of calculation

What is yield strength?

  • The stress associated with a non-proportional strain Ep is referred to as the “yield strength” (Rp 0.2).
  • Usually the technical elastic limit (at 0.01%), the 0.2 limit (at 0.2%) or the 1% yield strength is determined

What is the yield point?

What is patenting?

  • Patenting refers to the production of a fine lamellar pearlite structure in rod wire
  • Isothermal transformation can be achieved in low-alloy, largely eutectoid grades of steel
  • The wire attains high strength and ductility as a result of this heat treatment
  • Patenting by immersion in a bath is used to treat a wire coil; in the case of continuous patenting, the strands of unwound wires proceed next to one another through the heat treatment
  • Heating above the transformation point can be carried out in gas-heated furnaces or by means of resistance heating
  • Cooling takes place in a lead bath at 500 °C, or in air (air patenting)
  • The fine pearlite constitutes a favourable initial structure for subsequent drawing
  • In the case of multiple drawing, patenting is also repeated at intervals.Inventor: William Smith in 1870
  • The name “patenting” originated from the carefully guarded patent

Clover®Dome Spring Washers

Material for springs

 View PDF

  

What is the difference between a conventional Disc Spring and a Clover®Dome Disc Spring?

  • The Clover®Dome diaphragm spring is a conically shaped disc spring with specifically applied material reductions on the inner and outer diameter which results in a virtually uniformly circulating material strip and permits high deflections


    Tellerfeder Type Clover

 

  • The disc spring Clover®Dome has an overall height of approx. 10% of the outside diameter, while the standard disc spring has only approx. 3% of the outside diameter
  • The Clover®Dome disc spring therefore achieves a 2 to 3 times higher spring deflection than a conventional disc spring
  • The result is a slightly lower spring rate than with a conventional diaphragm spring, but it is significantly higher than with a compression spring
  • With a compression of approx. 75%, the spring returns to its original position and is not subject to settlement

    Weg-Kraft-Verlauf

  • The disc spring can also be compressed to a flat position for static purposes
  • Different displacement-force curves depend on the ratio lifting height/material thickness
  • The resulting edges are heat-treated without tension
  •  After fine stamping, the edges are rounded and the surface is machined to achieve the highest quality

 

 

 

 



 

Can Clover®Dome disc springs be stacked?

Clover®Dome disc springs can be stacked in parallel and serial layers

  • In contrast to conventional disc springs, up to 7 Clover®Dome disc springs can be stacked in parallel layers

All other wave washers

  • Compression type wave washers are normally used in thrust loading applications for medium deflections
  • These washers have a higher free hight and load than precision washers W61...
  • During initial installation the compression washers will take a slight set
  • Subsequent set after initial is minimal

What is the maximum force achieved by Wave Spring Washers?

Wave washer W61

In our table the force F1 is given for approx. 50% of the unstressed height Lo. In the case of static application and a flat position, one can assume that the maximum force is double the value shown for all parts with 3 waves.

  • With a parallel arrangement one achieves twice the force
  • All parts with more than 3 waves lengths below L1 should be avoided

 

What diameter tolerances do Wave Spring Washers have?

  • The inner and outer diameters are given for the flat position
  • The use of a wave spring does not change the outer diameter, while the inner diameter becomes slightly smaller

What characterises Wave Spring Washers?

  • Due to the triple wave, a three-line support is created when the wave spring washer is supported, which results in optimum force transmission, e.g. as a support for ball bearings
  • Precision type wave spring washers have defined load tolerances
  • Compression type wave spring washers do not have load tolerances
  • Wave spring washers are ideally suited for tolerance compensation
  • Wave spring washers can absorb vibrations; this results in smoother running and an extended service life for ball bearings

Material for springs

 View PDF

  

Where is the Spring Clip (Spring Clamp) used?

  • The spring clip (spring clamp) made of spring steel can fix pipes, tools, shafts and components with its clamping force
  • The spring clip can be fastened to the base with screws or blind rivets

What are the differences between the Spring Clips (Spring Clamps)?

  • The spring clip 1 (spring clamp) has a curved base. When attaching the clip, the base is pressed flat and the previously opened legs have a slight pretension, which tightens the parts to be held more tightly than with clips 2, 3, 4, 5. The fixing hole(s) of the clip are below the clamping area
  • The spring clips 2, 4 and 5 have a straight base. The parts to be clamped can easily be clipped into the slightly opened legs
  • The spring clip (spring clamp) 3 has a straight base with the fixing holes outside the clamping range. The parts to be clamped can easily be clipped into the slightly opened legs
  • The spring clip (spring clamp) E has a straight base with the clamping range increased to the base. The parts to be clamped can easily be clipped into the slightly opened legs

 

What surfaces do the Spring Clips (Spring Clamps) have?

  • The spring clips (spring clamps) can be supplied in galvanised spring steel
  • The range also includes PVC coatings in either white or black
  • This form of coating protects sensitive components that are too tight from surface damage or it is simply an optical variant

Extension Springs

What preloading is provided for Extension Springs?

  • In the manufacturing of cold-formed extension springs an internal preloading of the spring can be generated depending on the strength of the material
  • When the spring expands, a force must be applied so that the coils are moved apart and evenly spaced from one another
  • In the automatic production of tension springs, lower preloads are achieved than on winding benches

What is the spring rate or spring constant of Extension Springs?

  • If the spring rate c=N/mmis multiplied by the travel s=mm and the preload is added, the spring force F is obtained in Newton F= c*s + F0
  • “Spring rate” and “spring constant” are synonymous terms
  • As a rule there is a linear deflection-force ratio.In the case of extension springs, the linear force-deflection curve can begin at an elevated level due to the pretension generated during winding

What surfaces are provided for Extension Springs?

  • Extension springs made of spring steel 1.1200 are oiled
  • Extension springs made of stainless spring steels are dry, not oiled

What loop configurations and positions are available for Extension Springs?

  • Our extension springs have whole German loops acording DIN 2097, with variable loop positions since the number of coils are used as tolerance compensation during manufacturing

What is the inside loop diameter of Extension Springs?

  • The inside loop diameter is 0.9 times the inside diameter of the spring body

What is the service life of Extension Springs?

  • The life cycles of springs with the designation 0T... and 0C... is approximately 50000 strokes at L1 with a stress factor of 0.5
  • For normal operation, the spring should not be loaded beyond L1
  • The actual service life depends, among other things, on the spring travel between the deflection points and their position relative to the spring length
  • Our engineers would be pleased to help you with the design and recalculation of your application problem

What tolerances do torsion springs have?

  • The torque is tolerated with +-10% at the specified torsion angle
  • The outer diameter is tolerated with +-5%

What types of ends are provided for torsion springs?

  • Straight ends are standard
  • We produce special ends upon request

What material are Torsion Springs made of?

  • The material used is stainless spring steel, material number 1.4310

Which installation instructions must be observed for Torsion Springs?

  • Our torsion springs are used to absorb and release forces
  • The specified torques are intended for standard applications and static loads
  • A very good service life for dynamic loads is achieved if the torque is reduced by approx. 40%
  • Torsion springs are normally guided over a mandrel
  • The specified mandrel diameter M/S gives 10% clearance between the spring and the axle
  • For larger stresses, the mandrel diameter must be reduced
  • Axial play should also be taken into account during installation in order to ensure proper function
  • Use the spring in the direction of the winding
  • If the spring is used in the opposite direction to the winding direction, it is bent over the stretched fibre and the service life is considerably shortened

 

How large should the shaft diameter for Torsion Springs be?

  • The shaft diameter must be dimensioned so that there is clearance between the inner diameter of the torsion spring and the shaft at the maximum torsion angle of the torsion spring
  • The dimension M/S indicates the maximum shaft diameter at which clearance still exists when the torsion spring has reached the angle of rotation specified in the catalogue

  • The smallest bending radius is r=1d and applies up to a wire diameter of approx. 4mm

Constant Force Springs

Material for springs

Where can the Constant Force Spring be used?

  • Constant force springs are a special type of extension spring
  • They consist of a spiral, which is constructed in such a way that each turn touches the next turn slightly
  • When the spring is deflected, frictional resistance and deflection force act in opposite directions so that an almost constant force is produced
  • The constant force spring is designed for long spring travel with constant force
  • In practice, the spring is fixed firmly to a drum, with the free end absorbing the load
  • This principle can be reversed
  • The spring can be used flexibly, since the force values can be increased or decreased by tandem arrangement or counter-rotating arrangement

How is the Constant Force Spring mounted?

  • Slide bearings (drums) or ball bearings can be used for mounting
  • At least 1½ windings must remain on the drum when the spring is fully expanded
  • It is not necessary to attach the spring to the drum
  • The sufficient wrap angle prevents slipping
  • The ideal drum diameter is 15-20% larger than the relaxed inner diameter of the constant force spring

  • Da=outer diameter [mm] =+-10%
  • F=force [N]=+-10%

Garter Springs

Material for springs

 View PDF

  

What are Garter Springs used for?

  • Our interlock garter springs are extension springs with the ends fastened together to form a ring
  • They are primarily used to maintain controlled pressure of a radial lip seal on a shaft and to compensate for lip wear, changes in volume or stiffness of the elastomer, and the effect of temperature changes and time
  • Other uses include small motor belts and electrical connectors
  • Garter springs can easily be shortened to the required length and a relatively firm connection of the spring ends can be achieved by connecting the cylindrical and conical ends together
  • In critical applications, the connection can be fixed through laser welding

 

 

What is the tolerance of the Garter Spring?

  • The tolerance for the outside diameter of Garter springs is da +-0,13mm
  • The tolerance of Garter springs at the force at 4.75 mm deflection is +-10%
