本文对目前国外引进的几种主要型号采煤机的摇臂形星齿轮传动机构进行比较详细的分析,提出合理的行星传动机构,并建议采用综合性能指标来评价采煤机行星传动机构性能的优劣.在消化国外采煤机设计参数的基础上,综合了三种行星传动齿轮变位系数选取的基本原理和计算方法,分析了合理的变位系数选取与其它啮合参数的变化关系,并列表计算了几种引进采煤机行星传动齿轮的主要几何参数.
This paper analyzes the rocker arm gear mechanism of several main types of shearer introduced in foreign countries in detail and puts forward a reasonable planetary gear mechanism and proposes to use the comprehensive performance index to evaluate the performance of shearer planetary gear mechanism On the basis of digesting design parameters of overseas shearer, this paper synthesizes the basic principle and calculation method of selecting three kinds of planetary transmission gear displacement coefficient, analyzes the relationship between reasonable displacement coefficient selection and other meshing parameters, and The list calculates several major geometrical parameters for the introduction of sheave planetary gears.
