目前，潜孔钻机普遍采用冲击回转凿入系统，用以产生回转力矩，对岩石产生剪切作用而成颗粒分离。
Currently, the DTH RIGS use generally a percussion rotary penetration sys-tem to generate the rotating torque that produces a shearing action for breaking rock.
如果不能做到这一点，筒子的回转力矩会使它继续转动并退绕纱线，而退绕的纱线不能被卷绕到新卷装上。
If this is not done, the rotational momentum of the spool will cause it to remain in motion allowing yarn to be unwound without being taken up.
振动力完全平衡后机构的振动力矩，可通过调整附加机构中偏心齿轮的回转中心得到部分平衡。
The shocking moment after the complete balance of shocking force can get partial balance through the adjustment of eccentric gear in the attached mechanism.
