The Summary of the Rolling Bearing Contact Fatigue Failure Mechanism and Fatigue Life Model

To prolong the fatigue life,most of all,to extend the rolling contact fatigue life(FCF) of rolling bearing,is a very important research project for bearing staff at all times.This article first summarizes the rolling bearing contact fatigue failure mechanism and reasons of the formation and sum up of the rolling bearing contact fatigue life calculation in the different stages;then analysis the distinction among the different models of rolling bearing contact fatigue life.Finally a surface coating of the rol...
