摘要

齿轮静动态啮合特性研究对提高齿轮承载能力和动力学性能具有很高的理论价值。主要通过试验和有限元对比的方法研究齿廓修形量的变化对齿根弯曲应力的影响。试验中采用机械功率封闭的标准FZG齿轮传动试验台,并通过导电滑环的使用实现了齿轮传动过程中齿根弯曲应力的动态测量。通过试验和有限元分析得到的主要结论有:齿廓修形可以明显地降低齿轮传动过程中齿轮副的齿根弯曲应力;齿轮副的转速越高,齿廓修形对齿轮副齿根弯曲应力的改善情况越明显。

Abstract

The study of static and dynamic meshing characteristics of gears has high theoretical value for improving gear carrying capacity and dynamics performance. The influence of tooth profile modification on bending stress is studied by experiment and finite element. The standard FZG gear drive test rig is used to measure the bending stress of the tooth root,and carbon slip rings is used to measure the bending stress of the tooth root dynamically. The main conclusions from the test and finite element analysis are as follow: the tooth profile modification can obviously reduce the tooth bending stress of the gear pair during the gear transmission,the higher the rotational speed of the gear pair,the more obvious the improvement of the bending stress of the tooth profile modification.
