Enhancing Coal Shearer Traction Units: Gearbox Optimization and Industry Applications

Abstract

As the modernization of the coal industry advances, the haulage department of coal mining machinery faces elevated demands. Two fundamental requirements imposed on the haulage unit of shearers by the contemporary coal industry are increased traction and reduced size. Addressing the issue of the excessive volume of the traction unit, the reduction in size is accomplished by enhancing the transmission mode of the reduction unit, configuring the gear ratios of transmission gears at various levels, and optimizing the gear parameters at each level.
