Need the same force at all positions? You need a constant force spring

 

There are a number of different types of Constant Force Springs. More often than not they are made from steel strip. The most familiar function of a flat strip constant force spring is the tape rule, which allows you to pull out the tape all the way and requires no more effort from start to finish.

Constant force flat strip springs are manufactured from either texture rolled carbon steel or high strength stainless steel, depending on the application. Sometimes people confuse them with Power Springs (commonly called Clock Springs or Spiral Springs), which have a similar construction.

Constant force springs are seen in many applications:-

  • Seat belts
  • Brush springs for motors
  • Counterbalance for sash windows
  • Cable retractors
  • Timers
  • Plus many more

Although sometimes expensive to produce, their functionality often outweighs the unit cost. They are currently seeing resurgence in children’s toy applications as an environmental alternative to batteries.
