Analysis and stabilizing design of self-excited oscillation in a loading cam using a wedge effect

This paper describes a design method of friction reducer device using loading cam to suppress unstable vibration. Nonlinear simulation and energy analysis numerical solutions demonstrates that destabilization is caused by the large phase difference between slipping velocity in translation direction rotation direction. It was found similarly vibration occurs various structures wedge rollers with translational rotational motion. The analytical equation could be simplified focusing on motion factor affects slip power transmission surface, which Consequently, for suppressing expressed mathematical formula. validated results experiments conducted previous work current authors. Furthermore, from this equation, we proposed suppressed parameter balance without damping. surface slips when quick torque input damping used. can handle response reduce weight reducer. Specifically, shape roller made lighter, so moment inertia not lowered, or set as small roller.
