有链牵引采煤机的牵引方法是依靠固定在机体上的链轮与二端固定的煤机大链啮合而沿工作面溜子滑行。正常情况下,无论采煤机停在什么位置,煤机左右两个方向上的煤机大链在重力的作用下,都有一定的悬垂度,当煤机重新起动牵引时,链轮拉紧煤机大链,大链受横向拉力 Chain traction shearer traction method is to rely on fixed on the body of the sprocket and the two ends of the coal fixed chain meshing along the work surface slides. Under normal circumstances, no matter where the shearer parked coal around coal machine in both directions of the coal under the action of gravity, there is a certain degree of overhang, when the coal machine to restart the traction, the sprocket tension Coal machine chain, the chain by the lateral pull
