摘　　要：针对摇臂在加载试验过程中出现的行星减速机构运转异响和噪声大的问题,从构成行星减速机构的各零件制造工艺进行原因分析,并从齿轮加工的参数、刀具、工艺等方面提出改进方案。通过实践验证,经过制造工艺的优化改进,行星减速机构稳定性得到了大幅提升,解决了行星机构运转异响,并有效降低了啮合噪声,延长了采煤机齿轮传动系统的使用寿命。Aiming at the problems of abnormal sound and loud noise of the planetary gear reducer during the rocker arm′ s loading test, improvement scheme was proposed based on the analysis of manufacturing process of each part of the planetary gear reducer, and the parameters, tools, technology,etc. of gear processing. Through experimental verification, after the optimization and improvement of manufacturing process the stability of the planetary gear reducer has been improved significantly,abnormal sound of planetary gear reducer has been solved, the meshing noise has been effectively reduced,and also the service life of the coal mining machine gear transmission system has been extended.
