Comparative Simulation Analysis of Toothed Track Wheels with Different Tooth Shapes of Coal Mining Machine
Aiming at the frequent occurrence of wear,fracture,plastic deformation and other forms of failure of the toothed rail wheel of the travelling mechanism of the coal mining machine due to the poor production conditions in actual production,on the basis of the analysis of the meshing characteristics of the toothed rail wheel to obtain the poor working conditions,we constructed the pin-rail-toothed-rail wheel mesh model based on Pro/E,and completed the setting of the load and boundary conditions in conjunction with the working conditions,focusing on the comparison of the contact stress and bending stress of the domestically produced and imported toothed-rail wheel in three different working conditions.Focusing on the three different working conditions of domestic and imported toothed rail wheel contact stress and bending stress comparison,concluded that the performance of imported toothed rail wheel is better than domestic toothed.
