| Abstract: | Analysing C. . b's theory of the bit critical speed Of hole diggers during soil lifting,this paper makes a study of the motion and received-forces conditions of a soilunit body on the spiral surface of the bit. The calculating formula for the critical rotationalspeed of the bit has been derived and applied to a practical calculation. |
