新型驱动桥主动螺旋伞齿轮的装配方法

驱动桥主动螺旋伞齿轮总成装配时，主动螺旋伞齿轮处的轴承要有合适的预紧载荷。为减少该总成频繁拆卸，有效保护锁紧螺母、旋转油封和轴承的精度，利用装配过程模拟挑选出合适高度的隔套，使轴承的预紧载荷值在使用范围之内，达到降低劳动强度和提高装配精度的目的。

Assembly Method of Spiral Bevel Pinion in a New Type of Drive Axle

When spiral bevel pinion assembly in drive axle is installed, there is a proper pre-tightening load at the bearing of spiral bevel pinion. In order to reduce frequent disassembly of the part and to protect the locking nut, rotating oil seal and the bearing accuracy, a spacer sleeve with proper height is selected by assembly procedure simulation, which ensures the pre-tightening load value of the bearing in operation range and. at the same time, the labor strength is decreased and assembly accuracy is increa...
