SANTA MARIA, CA — Helical Products Company’s “machined” springs can provide linear deflection rates. Unlike traditional wire wound springs, virtually all residual stresses are absent. There are no internal stresses to overcome before deflection occurs, which can be the case with traditional springs. With machined springs, all coils deflect under load.
One big advantage of machined springs with two or more integral coils is that not only are there redundant elastic elements should a failure occur, but a failed element (coil) will be physically trapped by a second coil, (or multiple coils). In many cases a broken spring will continue to function.
There is no tendency for machined springs to squirm when deflected and no restraint is required to resolve the free moment. Multiple starts (coils) make loading points irrelevant on the radius of the spring and also increase parallelism accuracy. With machined springs, perpendicularity, parallelism, lateral bending, axial and torsional rates can be for all intents and purposes guaranteed.
