对一些车型主减速器使用情况的分析表明,尽管轴承寿命的计算值与轴承样本中的规定值相符,甚至超过该总成规定的里程标准数倍,但轴承寿命不足仍是整个总成使用可靠性降低和过早损坏的原因之一。在提高主减速器和其它总成的轴承使用寿命中,存在的问题不仅表现在对装配过程中总成超差参数造成的问题研究不够,而且还表现在装配精度方面缺乏一定标准。这个问题中最本质的一点是,对影响主减速
Analysis of the use of some final drives shows that although the calculated bearing life is in line with the specified values in the bearing samples even several times the mileage standard specified for the assembly, insufficient bearing life is still a reliable indicator of overall assembly reliability One of the reasons for the decreased sexual and premature damage. In improving the service life of the main reducer and other assemblies, the existing problems are not only the lack of research on the problems caused by assembly tolerance parameters in the assembly process, but also the lack of certain standards in assembly accuracy. The essential point in this question is to influence the main deceleration
