滚动轴承是承受载荷的相互滚动接触的零件,工作表面的剥落是其损坏的主要形式之一,这是轴承钢表面疲劳化,并且渗透到接触表层达到一定深度的结果。 轴承的疲劳剥落起始于钢中的夹杂物,这一结果已被人们广为接受。大量实验表明,轴承钢中非金属夹杂物的等级及类型是影响轴承滚动接触疲劳寿命及其他机械性能的重要因素。 Rolling bearings are load-bearing parts in rolling contact with each other, the working surface is one of the main forms of damage, which is the result of fatigue of the bearing steel surface and penetration to the surface to a certain depth. Fatigue spalling of bearings starts with inclusions in steel and this result has been widely accepted. A large number of experiments show that the grade and type of non-metallic inclusions in bearing steel are important factors affecting the rolling contact fatigue life and other mechanical properties of the bearing.
