Reference to the domestic and international thick seam Shearer circumstances, Cutting completed the electrical power of 180 KW total installed power of 450 KW of cutting-cylinder hydraulic traction Shearer Whole program design and right shearer cutting focus of the Department of Design. Host overall body structure, eliminating a long stud, and the traditional sense of the bolt; This structure is simple, reliable, and small size, greatly reducing the height of Shearer's fuselage. Cutting Part 4 used to drive before three straight tooth drive, the fourth level of planetary transmission. The former three straight drive gear teeth through the direct transmission of the general design principles, designed for cutting the Department of Gear were divided into a closed shaft, the shaft an inert, as of two shaft, up 3 shaft, and inert two shafts; using two inert shaft is the innovation in design, It is a drive to meet the strength to meet the demands of the cutting height on the cutting Minister degree requirements. In the fourth grade planetary transmission, and use Win two KH planetary reducer design principle, designed for cutting the Department of a two-KH planetary reducer, and it will directly link drum, greatly simplified the cutting of the design, saving materials and space. In addition to cutting the Department of the other parts such as clutch, which spray system also carried out a detailed design and a calibration.
