Linear Springs

Product catalog summary

Overview of Smalley Linear Springs
Smalley Linear Springs are continuous wave-formed wire lengths made from spring-tempered materials. They function as load-bearing devices with similar load/deflection characteristics to wave springs. These springs are used in various applications, including detent preload and rotary vane pumps, to provide precise load and resistance.

Specifications and Formulas

Single Wave Linear Spring (N=1):
Deflection: f = (P * L^3) / (4 * E * b * t^3)
Operating Stress: S = (3 * P * L) / (2 * b * t^2)
Multiple Wave Linear Spring (N>1):
Deflection: f = (P * L^3) / (16 * E * b * t^3 * N^4)
Operating Stress: S = (3 * P * L) / (4 * b * t^2 * N^2)

Material and Sizes
Stock sizes are available in carbon and stainless steel, with over 200 sizes. Special orders can be made with no tooling costs and exotic alloys.

Applications

Detent Preload: Used to load pins in grooves for specific rotational positions.
Rotary Vane Pump: Used to radially load vanes for better sealing against the bore.

Linear Spring Applications Rotary Vane Pump Smalley Linear Springs are used to radially load the bottom of the vanes in the pump. The springs energize the vanes against the bore for better sealing. Detent Preload Smalley Linear Springs are used to load pins that are positioned inside grooves so a rotating element can detent to specific positions. The springs are designed to exert a precise load to give the rotation a desired resistance. Engineering Smalley Linear Springs are a continuous wave formed (marcelled) wire length produced from spring tempered materials. They act as a load bearing device having approximately the same load/deflection characteristics as a wave spring.
