钻机用柴油发电机组两主轴对中问题的探讨

Alignment of two main shafts of diesel generator set for drilling rigs.

钻机用柴油发电机组两主轴轴线的对中效果不理想 ,会导致联轴器的早期失效 ,并影响整个系统的工作质量。两主轴的正确对中方法是通过对联结盘和飞轮的找正 ,使联结盘和飞轮既平行又同心来实现的。找正时 ,先将柴油机和发电机固定于同一底盘 ,然后 ,通过测量 ,判断两轴在空间的相对位置并确定其相对位移量 ,再改变发电机的支脚螺栓的垫片厚度及移动发电机主轴位置 ,来达到两主轴轴线同轴。对中测量时 ,用轴销将飞轮和联结盘松动连接 ,使两主轴一起转动。对中调整时 ,必须先调整发电机主轴轴线与柴油机主轴轴线平行后 ,再调整两轴线同轴。这种对中方法也适用于其它机械的轴对中装配。

Inaccurate alignment of the axes of the two main shafts on the diesel engine and electric generator for drilling rigs will result in early failure of the shaft coupling. Accurate alignment of the shafts can be realized by centering the coupling disk and the flywheel to make them parallel and concentric. The approach to the shafts alignment is offered and the points for attention are given.
