滚动轴承的磨损与维护一、轴承的磨损现象１．疲劳破坏（即点蚀）轴承的内外滚道及滚动体，都要受到周期性的脉动载荷，从而产生脉动的接触应力，当轴承使用时间过长时，这个应力的循环次数越来越多，达到一定数值后，这些受力体就会出现疲劳小裂纹。继续下去，由于应力作... Rolling bearing wear and maintenance First, the phenomenon of bearing wear 1. Fatigue damage (ie, pitting) bearing inner and outer raceways and rolling elements, are subjected to periodic pulsating load, resulting in pulsating contact stress, when the bearing is used for too long, the stress cycle more and more, After reaching a certain value, these stress bodies will appear fatigue crack. Keep going, due to stress ...
