Conpower® Springs and Power Springs

Vulcan Spring is a leading designer and manufacturer of power springs (also known as clock springs), including Conpower® springs and conventional Power Springs. Conpower® is Vulcan Spring’s brand name for its pre-stressed power spring, a brand that is well known and highly respected for quality throughout the world.

Vulcan Spring's Conpower® and conventional power springs are formed by winding a strip of material on an arbor and into a case or retaining ring to create a compact power source. Rotational torque is obtained from a center arbor or from the case. This torque increases throughout the total winding of the spring. Conpower®springs, compared to conventional power springs:

  • Are pre-stressed to produce a flatter torque gradient
  • Can be used to increase the number of turns in a case of a given diameter

Both Conpower® and conventional power springs provide rotational energy from either the arbor or the case, or linear motion with the use of a pulley or cable. Power springs are sometimes referred to as clock springs.

Technical Considerations for Power Springs

Design criteria for both types of power springs - Conpower® springs and conventional power springs - are the same. The decision to use a conventional power spring or Conpower® spring is based on the application. A Vulcan engineer can help with this determination. Important considerations for designing and manufacturing power springs include:

  • Arbor size (see A in Diagram)
  • Inside diameter (I.D.) of case (See B in Diagram)
  • Available case width (See C in Diagram)
  • Turns required
  • Torque required
  • Location of center eye/tab
  • Life cycle requirement in total estimated uses
  • Environment in which the power spring will be used
  • Mounting requirements for case and arbor
