As the main mechanical equipment for fully mechanized coal mining,the shearer plays a very important role in the entire coal mining process.The guide shoe is one of the components of the external traction system of the shearer.In practical applications,failure often occurs,mainly manifested as fracture and wear on the contact surface.Once a failure occurs,the shearer has to stop running,which not only seriously affects the production efficiency of the coal mine,but also brings safety hazards.Therefore,it is very necessary to improve and study the performance of the guide shoes of the shearer.
