An Analysis of Coal Mining Machine Toothed Track Wheel and Pin Row Engagement Based on Abaqus
At present,the coal mining machine mainly adopts toothed rail wheel-pin row traction mode,and both of them often have serious tooth surface wear and even tooth fracture and other phenomena;by analysing the 126 mm pitch toothed rail wheel produced by a company and the mainstream two types of pin row mesh on the market,it can provide the basis of the matching between the toothed rail wheel and the pin row;on the premise of not changing the tooth shape of the toothed rail wheel and the pin row without increasing the cost,the matching can be prolonged by reasonable matching between the toothed rail wheel and the pin row.On the premise of not changing the tooth shape of the wheel and pin and not increasing other costs,the service life of the wheel and pin can be extended through reasonable matching.In the gear wheel and pin row of the meshing process tooth surface often appear wear,and wear related to the main factors is the contact stress,so the use of Abaqus software were established two groups of gear wheel-pin row meshing model for finite element analysis,and analysis of contact stress;contact stress fluctuation is small and smooth decline of a group of model matching is more good,in the actual production of the proposed group of gear wheels and pins with the row with the In actual production,it is recommended to use this group of toothed track wheel and pin row together.
