The design of shearer drum
Abstract
The shearer is a medium-low power electric haulage shearers mining medium-thick seam, for coal seam thickness , mining height ,coal bed pitch less than it, it can be used for hard coal mining.
This pleted 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 ponents,it also introduced the specific structure of shearer rocker.
In the design process, completed the calculation and design of the reducer drive scheme and ponents. First, completed the rocker reducer transmission ratio , speed and transfer power distribution calculation. Secondly, pletion 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 ary gear train. Thirdly, pletion of the selection and check the spline for connection. Finally, the three-dimensional modeling.
