螺旋滚筒式采煤机在工作时，如果旋叶上截齿为重复排列方式，则会产生沿滚筒轴线方向指向煤壁侧的轴向力，旋叶装煤时也将产生指向煤壁方向的轴向力。2种轴向力的存在对采煤机截割部的工作有很大危害，必须加以平衡。经过理论分析及实际工作证明，采用端盘L设置不同个数和不同 Spiral drum shearer at work, if the rotation of the pick on the teeth for the repeat arrangement, it will produce along the axis of the cylinder wall pointing to the axial force of coal, rotary vane coal will also have a point to the direction of the coal wall Axial force. The existence of 2 kinds of axial forces has a great harm to the work of shearer cutting department and must be balanced. After theoretical analysis and practical work to prove that the use of the end plate L set a different number and different
