薄煤层采煤机摇臂输出轴轴承特性分析

摘要

Research on the output terminal bearing of rocker arm coal mining machine ,using the project team to develop the coal mining machine load simulation program to get the force curve ,through the analysis of the whole force of the coal mining ma-chine,get the load of output terminal bearing .Comprehensive consideration of the constraints of the bearing in the work and the external environment and other factors , using ANSYS-DYNA to display the dynamic simulation , establish to the finite element model of bearing ,obtain the stress characteristics of the bearing ,in order to provide a basis for futher research on the motion characteristics of the rolling bearing of the output terminal .%研究采煤机摇臂输出轴轴承,利用项目组开发的采煤机载荷模拟程序得到采煤机受力曲线,通过对采煤机的整体受力分析得到输出轴轴承的载荷.综合考虑轴承在工作中所受到的约束及外界环境等因素,利用ANSYS-DYNA软件对其进行显式动力学仿真,建立轴承的有限元模型,获取轴承的应力特性,为进一步研究输出轴轴承的运动特性提供了依据.
