Influence of Installation Clearance of Pin Row of Coal Mining Machine on Contact Performance of Driving Wheel
Taking the driving wheel of MG132/320-WD coal mining machine and pin row as the research object,the meshing process of driving wheel and pin row was analysed,and the results showed that the maximum stress and the maximum deformation of the teeth of the driving wheel appeared in the position of the root of the teeth involved in the meshing.The influence of the installation clearance of the pin row on the contact stress of the driving wheel is analysed,and the results show that the larger the installation clearance of the pin row is,the larger the maximum contact stress suffered by the driving wheel when it engages with the pin row,which provides a very good technical support for the on-site installation of the pin row of the coal mining machine.
