Performance Improvement of Shearer Running Sprocket
The running sprocket is one of the main parts of the shearer's running gear.In recent years,due to the demand of the market,the shearer is developing in the direction of high power and large mining height.However,the high power operation of the shearer is easy to cause the failure of the running sprocket.Tooth fracture,tooth surface wear and tooth plastic deformation are the main failure forms of running gear sprocket.Once the failure phenomenon occurs,it will bring great safety risks to coal mine production,and seriously affect the production efficiency of coal mines.Therefore,the experimental analysis on the performance improvement of shearer sprocket was carried out.
