摩托车发动机曲轴上的单列向心滚珠轴承,当其轴向间隙和径向间隙过大时,就必须更换新件。对于一些没有微分表测量工具的单位,只能凭手的感觉来判断间隙的大小,这是很不准确的。为此,我们介绍一种应用塞尺(厚薄规)来测量轴承轴向间隙和用游标卡尺测量轴承径向间隙的方法,简单方便,误差较小。 Motorcycle engine crankshaft single row radial ball bearings, when the axial clearance and radial clearance is too large, it must be replaced with new pieces. For some units without differential measuring instruments, it is very inaccurate to judge the size of the gap only by the feeling of the hand. To this end, we introduce a method using feeler gauge (thickness gauge) to measure bearing axial clearance and measure bearing radial clearance with vernier caliper, which is simple and convenient with less error.
