摘要

采用Matlab与Excel联合编制了采掘机械行星齿轮强度校核软件,软件以采掘机械动力学仿真中的接触法向力作为软件的输入,通过输入齿轮必要的设计及材料参数,便可实现齿轮齿面接触应力及齿根弯曲应力的校核,解决了传统分析中齿轮受力无法确定以及采用有限元软件无法求解齿根弯曲应力、求解接触应力时间过长的不足。以某公司生产的EBZ220型掘进机为例,通过校核发现该掘进机截割机构的二级行星轮齿根弯曲应力不满足强度要求,该掘进机不适合以1.38 m/min截割f值为8的岩石。研究为齿轮强度校核提供了一种新的的理念和方法,具有重要的理论意义及较强的工程应用价值。

Abstract

The planetary gear strength checking software has been developed by combined programming of MATLAB and EXCEL. Take the contact normal force from mining machinery dynamics simulation as the input of the software with other necessary gear’s design and material parameters,the software can achieve gear tooth surface contact stress and root bending stress checking. The shortages of unable to determine the gear force in traditional analysis,unable to solve bending stress and solve contact stress for a long time by using the finite element software have been solved. Taking the EBZ220 roadheader as engineering object,though the checking result,the roadhead cutting unit’s second stage planetary gear’s root bending stress does not meet the strength requirement,that means this roadhead Not suitable for cutting rock,whose f value greater than 8 at the speed 1. 38 m/min. this research provides a new concept and method for gear strength checking,which has theoretical significance and strong engineering application value.
