2008-7-22 · 1.. IntroductionThe linear theory of vibration isolation is well documented in the literature,,, .A linear isolator attenuates transmitted vibrations above an excitation frequency, Ω, which exceeds the value of 2 ω n, where ω n is the undamped natural frequency of the isolator. The transmitted force, F t (or displacement, X 0), reaches a value less than the excitation …

A shaft mounted gear reducer was used in most applications. These reducers had a fixed speed ratio between their input and output speeds generally of 5:1, 9:1, 15:1 or 25:1. This resulted in the use of v-belt and pulley speed reduction or speedup between the motor shaft and the gear reducer input shaft.
