On the critical amplitude in oscillating rolling element bearings

Small oscillating amplitudes (~0. 1°) and larger (> can both lead to wear, which complicates the evaluation of operating conditions. In this work, a simulation model is used discuss critical amplitudes. The parametric study, includes 125 simulations, shows effect load coefficient friction on frictional work density for ranging from 0.1 2.5°. study concludes that increases with amplitude up certain point, where it becomes almost constant in relation amplitude. This point reached when so large continuous overlapping contact zone no longer occurs. It precisely marks oscillation
