采煤机行走轮轮齿性能的优化研究

Research on Optimization of Tooth Performance of Shearer Wheels

行走轮作为采煤机中重要的组成部分,其轮齿失效会对整个机器的可靠性产生不良影响.基于此,对采煤机行走机构主要结构和原理进行简要介绍,利用有限元方法建立了行走轮轮齿与销排销齿的啮合模型,分析了两齿面接触时的情况,根据分析结果提出行走轮轮齿性能优化措施.

As an important part of the shearer,the walking gear failure will adversely affect the reliability of the entire machine.This paper briefly introduces the main structure and principle of the shearer walking mechanism.The finite element method is used to establish the meshing model of the teeth of the walking wheel and the pin row and pin.According to the analysis results,the measures to optimize the tooth performance of walking wheels are proposed.
