工程钻机圆锥滚子轴承的预紧装置

Pre-tightening Device for Taper Roller Bearing of Construction Drill

摘要:

分析了工程钻机在施工过程中轴承游动间隙对钻机的影响。提出了在钻机输出轴圆锥滚子轴承的外端，加装一套碟形弹簧预紧装置，有效地解决轴承的游动间隙。

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.
