Influence of Tooth Shape on Meshing Contact Strength of Coal Mining Machine Toothed Track Wheels
Aiming at the problem that the life span of domestic toothed rail wheel of coal mining machine is lower than that of imported toothed rail wheel,ABAQUS simulation and analysis software was used to complete the analysis of contact strength of two kinds of toothed rail wheels,and the results show that the maximum stress of imported toothed rail wheels throughout the meshing process is lower than that of domestic gears,which shows that the contact performance of the composite curvilinear tooth surface of the imported toothed rail wheels is superior to that of the domestic toothed rail wheels with involute tooth surface.At the same time,the imported toothed rail wheel toothed circle diameter,tooth thickness and root thickness are better than domestic toothed rail wheel.Therefore,low meshing contact stress and large structural size are the main reasons why the service life of imported toothed rail wheel is higher than that of domestic toothed rail wheel,and it is the key consideration direction for the optimisation of domestic toothed rail wheel.
