ABSTRACT
The MG160/390-WD shearer is a medium-low power electric haulage shearers mining medium-thick seam, for coal seam thickness of 1.5~2.92m, mining height 1.3~3.0m,coal bed pitch less than 35°, it can be used for hard coal mining.
   Double drum coal shearer。A mining full-seam mining machine, one at each end of the drum. Front roller in cutting top coal, after cutting drum in under ground coal. Two roller are generally dorsal rotation, the driver left drum left spiral, the driver right right helical drum. Can also rotate in the opposite direction, the driver on the left with the right spiral drum, the drum with a left screw driver. Generally use the two-way mining, advanced shift after the head of the oblique cutting knife; also can be used to feed at the same time shift head tangent feeding mode.
   This paper completed the design of shearer rocker arm, including the layout and three-dimensional modeling of speed reducer, it described the current  status of domestic and international coal mining research and future development trends, the type of shearer, working principles and main components,it also introduced the specific structure of shearer rocker.
In the design process, completed the calculation and design of  the reducer drive scheme and related components. First, completed the rocker reducer transmission ratio , speed and transfer power distribution calculation. Secondly, the completion of the design and check of five shafts and the shaft driving gears inside the rocker arm shell,simply introduced the assembly relationships and intensity checking of the planetary gear train. Thirdly, the completion of the selection and check the spline for connection. Finally, the three-dimensional modeling.
