[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.
