轴承的游隙是指套圈和滚动体间的内部间隙。对径向游隙来说,其意义为如将一个套圈固定,另一个套圈沿径向由一个极限位置到另一个极限位置的移动量。径向游隙又分为: (1)原始游隙:是指轴承在未安装到轴和轴箱内自由状态的游隙,即规范上的游隙。 (2)配合游隙:是指轴承安装到轴和轴箱以后的游隙。由于轴承内圈是从过盈形式与轴配合的,所以配合游隙小于原始游隙。 (3)工作游隙:是指轴承在实际运转状
Bearing clearance refers to the internal gap between the ring and the rolling body. For radial clearance, the meaning is the amount of movement of one ferrule in the radial direction from one limit position to the other limit position. Radial clearance is divided into: (1) The original clearance: refers to the bearing is not installed in the shaft and axle box free state clearance, that is, the standard clearance. (2) with the clearance: refers to the bearing installed to the shaft and axle box after the clearance. As the bearing inner ring is interference form with the shaft, so with the clearance less than the original clearance. (3) work clearance: refers to the actual operation of the bearing
