【摘要】：基于破煤理论建立了采煤机的力学模型,采用ADAMS建立采煤机刚柔耦合模型,并解决了边界条件添加、接触法向力提取等技术问题,分析了行星轴、架的可靠性;基于行星减速机构强度校核基本原理,开发了行星齿轮强度校核软件,以虚拟仿真中的动态接触法向力为输入,对某公司两种行星减速机构设计方案中各齿轮的接触应力和弯曲应力进行研究。该方法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。结果表明:二级行星减速机构采用4行星轮结构要优于采用3行星轮方案,传动更稳定、可靠。
[Abstract]:Based on the theory of coal breaking, the mechanical model of shearer is established, and the rigid-flexible coupling model of shearer is established by using ADAMS. The technical problems such as adding boundary conditions and extracting the contact normal force are solved, and the planetary axis is analyzed. Reliability of the frame; Based on the basic principle of planetary reducer structure strength checking, a planetary gear strength checking software is developed, with the input of dynamic contact normal force in virtual simulation. The contact stress and bending stress of each gear in two design schemes of planetary reducer in a certain company are studied. The method solves the problem that the gear force can not be determined in traditional analysis and that the finite element software is not able to solve the tooth root bending. Curved stress. The results show that the structure of the secondary planetary reducer is more stable and reliable than the scheme of the 3-planet gear, and the structure of the second-order planetary reducer is better than that of the 3-planet gear.
