Constant Force Springs Spiral Clockwork

A roll of the pre-stressed strip that applies a virtually constant restraining force to prevent uncoiling is called a constant force spring (also known as a power spring or a continual torque spring). Since the change in the radius of curvature is constant, so is the force. This is accurate if the buildup-induced change in coil diameter is ignored. Many designers have used continuous force springs in applications, including brush springs for motors, counterbalance springs for window sashes, and carriage return springs for typewriters because of their extended extension possibilities, consistent torque, and nearly zero intercoil friction. Mechanisms for cable retractors, movie cameras, and timers are powered by constant force springs. When using the spring, it is advised to have at least two wraps coiled. There are around 2000 cycles in the cycle life.

Although we manufacture several springs with conventional end fittings, we are pleased to provide a bespoke end fitting for your application if you need more than these to meet your demands. We have some of the quickest lead times in the business and can ship in any number, from a few springs to millions.

Tolerance

The strip tolerance determines the constant force spring's width tolerance, while the output roller and storage tolerance determine its diameter tolerance. Bore and torque tolerances are ±25% and ±10%, respectively. The length and thickness of the strip should be the reference dimensions.

Typical uses for the mainspring

Watches: The watch's central component is the mainspring, which releases elastic potential energy to drive the gears to spin and show the time.
Toys: Wind-up mechanisms power a variety of toys, including wind-up robots and wind-up toy automobiles.
Tape measure: The tape is automatically retracted by the spring inside the tape measure.

Roll-up doors: Some roll-up doors regulate their ascent and descent using a spring system.
Appliances: A spring offers auxiliary functionality or backup power in specific electrical gadgets.
Mechanical devices: Various mechanical devices, like spring clamps and switches, employ clockwork. the
