Abstract
MG600/1400-WD Shearer is linked with high-power electric traction Shearer, Shearer is Shearer cutting the Department of the main components of one of the main commitments with the latest coal and coal task. Cutting mainly by box, the original motor, the output shaft, the slowdown of the dust and cooling systems, lubrication system, and other components. Shearer cutting reducer mainly by the Ministry of fixed reducer and rocker slowdown from the planet composed of two parts, cutting mechanical transmission from two straight and two planetary gear transmission for transmission to achieve, Qiemo-round use of the sun floating Forms of planetary transmission. Rocker structure to take the form of increased drum of a loaded coal space further enhance the efficiency of coal; In order to adapt to different mining, through the replacement of a shaft and four-axis corresponding matching gear third gear transmission can be realized, the work achieved by the speed were 30.36 r / min, 35.2r/min, 40.6r/min. And at all levels and the corresponding drive shaft gear for the design calculations and the corresponding check, drawn Shearer cutting assembly of the structure of the plans and major parts map, the results meet the design requirements.
