东风中重型车单级减速器双曲面齿轮损坏的分析

单级双曲面齿轮减速器过去仅在轿车、轻型车的主减速器上采用，随着加工工艺水平的提高和双曲面齿轮油产量的增，近年来国内中、重型载货车的驱动桥也大采用。由于其本身所具有的使用条件及工作特性，用户在使用中往往会遇到双曲面齿轮损坏的问题，本文结合东风中重型车双曲面齿轮损坏情况进行分析。

Damage Analysis of Hyperboloidal Gear in Single Reducerin Dong Feng Medium and Heavy Duty Truck

In the past,single reduction hyperboloid reducers are only applied in passenger car and light vehicles.In r ecent years,with improvement of process quality and increasing of hyperboloid oil output,hyperboloid reducers are widely applied in domestic medium-heavy t rucks.Because of their working conditions and working characteristics,hyperbol oid failures usually occur during transport operation.Failure analysis is done with failures of DONGFENG medium-heavy truck hyperboloid reducers as instances .
