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
