Garter Springs

Design of Garter Springs

Design methods for garter springs are continuations of methods developed for helical compression and extension springs. Generally, they are designed with as low a rate as possible to provide a nearly constant force on a seal as it wears.

The garter is essentially a helical extension spring formed into a circular ring with the ends connected on the inside diameter. Thus a garter spring is an endless spring, ignoring that its ends are joined which does not affect the results and is easily identified in that it looks like a circle made up of a spring.

Joint Design and Considerations for Garter Springs

Garter spring ends may be fastened together by interlocking loops, staking one coil of the female end into the rib end, soldering (for belt applications) or by screwing one end into the other.

When considering garter spring design, its strength must be such that the joint will not separate when the spring is extended to its maximum diameter regardless of the connecting joint used.
