| Abstract: | Taking the cutting part of the MG300/700-WD shearer as the research object, used MATLAB programming to analyze the influence of different coal seam properties and the height and position of the gangue layer on the cutting force. The ANSYS Workbench software was used to analyze the dynamics of the high-speed end gears of the cutting part,and the nCode Design Life software was used to analyze the fatigue life. The positions that are prone to fatigue are the location of the contact of two gear tooth surfaces and the life is about 163 days, which is of great significance to the preventive maintenance of the shearer. |
