Constant Force Springs - Learn About - Lee Spring

The constant force spring is an excellent device for applications where a constant load is required. Some of the many applications of constant force springs are in counterbalances, door closers, cable retractors, hose retrievers, tool head returns, cabinet furniture components, gym equipment, hair dryers, toys, electric motors, appliances, space vehicles, and other long-motion functions.

Search for Constant Force Springs - Lee Spring

Constant Force Springs. A Constant Force Spring is a pre-stressed flat strip of spring material which is formed into virtually constant radius coils around itself or on a drum. When the strip is extended (deflected) the inherent stress resists the loading force, the same as a common extension spring, but at a nearly constant (zero) rate.

Constant Force Spring Design and Equations - Engineers Edge

Generally constant-force springs are constructed as a rolled ribbon of spring steel such that the spring is relaxed when it is fully rolled up. As it is unrolled, the restoring force comes primarily from the portion of the ribbon near the roll.

CONSTANT FORCE SPRINGS - lesjoforsab.com

The constant force spring consists of strip material, which has been shaped and pre-tensioned into a tightly wound roll. The spring is used in a linear movement and produc-es almost constant force throughout its deflection. Constant force springs can be fitted in a number of ways and extended partly or completely. There is practically no

Constant-force spring - Wikipedia

Generally constant-force springs are constructed as a rolled ribbon of spring steel such that the spring is in a rolled up form when relaxed. The approximation of "constant force" comes from a long travel and a pre-loaded rest position, so that the initial force does not start from zero but a finite value.
