Design and research on monitoring system of driving gear wear of shearer in coal mine production environment

The coal cutter is one of the key equipment for comprehensive mechanized coal mining in modern mines. In the production and use stage, the main factors that directly affect the safe operation of the coal cutter and the economic benefits of coal mines are gear strength and life span. Gear failure will lead to shearer equipment failure and production accidents, so it is of great significance to study the wear state of shearer transmission teeth for the normal work and daily maintenance of shearer. In this paper, the wear state of shearer drive teeth is studied, and a real-time monitoring system of shearer with certain integration and reliability is developed under the background of complex environment of coal mine. Through monitoring the physical and chemical properties of oil and wear particles, the change law and influencing factors of viscosity and wear debris morphology in the process of oil use are studied. The wear state of the transmission gear of the shearer is analyzed and studied, which provides a guarantee for the safe production of modern mines.
