SPRING HAVING A HIGH NATURAL FREQUENCY AND A LOW SPRING RATE

摘要

A compound spring (10,24) is disclosed that has the benefit of a low preload force and a relatively high natural frequency. In its most basic form it is a helical spring having a cylindrical section (#1) and a tapered section (#2). In the preferred embodiment the preload force is linear with increased spring deflection and the spring is unaffected by the harmonics of the surrounding machine. Deflection in the axial direction is a small percentage of the free length. In the preferred embodiment the wire cross-section is constant.
