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 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.

滚筒采煤机的工作原理
双滚筒采煤机工作时,前滚筒割顶煤,后滚筒割底部煤并清理浮煤。(双滚筒采煤机的工作原理如图1.2所示)因此双滚筒采煤机沿工作面牵引一次,可以进一次刀;返回时,又可以进一刀,即采煤机往返一次进两次刀,这种采法称为双向采煤法。
