变速器滚子轴承常见失效原因分析

Common Failure Reasons Analysis for Transmission Roller Bearing

变速器中输入轴、被动齿轮和行星齿轮常用圆柱滚子或滚针轴承支撑,因设计和制造原因,有时会出现早期失效。本文论述了重型特种车辆变速器中两种典型的滚子轴承失效机理,并提出了相应的解决方法。

Based on the sometimes occurredearly failureproblems ofthe cylindrical roller or needle bearing support commonly used in transmission input shafts,passive gears and planetary gears,due to design and manufacturing reasons.Two typical discusses two typical failure mechanisms for roller bearings of heavy-duty special vehicletransmission,and corresponding solutions are proposed.
