滚动轴承内、外环滚道和滚动体之间的间隙称作游隙,是轴承的重要精度指标。轴承游隙的大小,不仅影响轴承装配的旋转精度,而且对轴承的工作性能和疲劳寿命也有直接影响。因此,准确地保证轴承的游隙值,是轴承装配工作过程中的重要环节。一般轴承的游隙,是在装配过程中,凭实际经验经过多次合套选配而得到的。这种多次选配的过程,往往造成轴承滚道和滚动体的表面划伤,破坏 Rolling bearing, the outer ring raceway and the gap between the rolling body is called clearance, is an important indicator of precision bearings. The size of bearing clearance, not only affects the accuracy of bearing assembly rotation, but also the bearing performance and fatigue life also have a direct impact. Therefore, to accurately guarantee the bearing clearance, bearing assembly process is an important part of the process. General bearing clearance is in the assembly process, with actual experience after many sets of matching and get. This multiple matching process, often resulting in bearing raceway and rolling body surface scratches, damage
