| Abstract:The effect of the bearing travel clearance on the drill in the operations is analyzed. It is proposed that a disc spring pre tightening device be fixed on the outer end of the taper roller bearing of the output shaft of the drill, which effectively eliminates the bearing travel clearance. |
