Experimental studies on the dynamic characteristics of rolling element bearings

摘要

The effect of varying parameters on the stiffness and damping of an angular contact ball bearing was studied under rotating conditions. Axial and radial preloads have the most significant effect on dynamic characteristics of bearings, as there is a dependence of the characteristics on oil viscosity. The differential heating of the bearing components could also be a very sensitive factor. It was concluded that the joint between the bearing and the housing has a significant effect on the total dynamic characteristics of the bearing assembly.
