滚动轴承疲劳寿命的影响因素

对影响滚动轴承疲劳寿命的各种因素进行了综述，包括各种疲劳诱导应力(最大切应力、最大动态切应力、Von Mises应力和八面切应力)，切向力、残余应力和环向应力疲劳极限应力、表面粗糙度、弹流润滑、表面处理、润滑油中污染颗粒、温度、速度、不失效寿命和钢材纯净度(氧含量)的影响，为轴承寿命的准确预测提供参考。

Influence Factors on Fatigue Life of Rolling Bearing

The influencing factors on fatigue life of the rolling bearing are reviewed, such as fatigue inducing stresses which including the maximum shear stress, the maximum dynamic shear stress, Von Mises stress and octahedral shear stress, shear force, residual stress, hoop stress, fatigue limit stress, surface roughness, elastic hydrodynamic lubrication, surface treatment, contaminant in oils, temperature, speed, no failure life and oxygen content in steel etc. It is pointed out that the fatigue life of the rolling bearings is influenced and dominated by many factors, the profitable guide has been made to increase fatigue life of the bearings and to increase correct prediction of the bearing life and to improve design of the bearings.
