Research on Traction Characteristics of Coal Mining Machine with Dual Motor Drive
In order to further improve the productivity and reliability of the coal mining machine,the traction drive system of the coal mining machine is taken as the research object,based on the comprehensive analysis of its structure and main parameters,the virtual prototype simulation model of the coal mining machine is established on the basis of ADAMS software,and the accuracy of the virtual prototype model is verified through the kinematics and dynamics analyses of the model;finally,it is found out that the clearance of the pin-rail connection is the main reason of load impacts on pin rails and pin wheels,and also the main reason of broken teeth of the pin wheels.Finally,it is found that the gap between the pin-rail connection and the pin wheel is the main reason for the load impact between the pin rail and the pin wheel,which also leads to the broken teeth of the pin wheel.
