In order to solve the problem that when an existing screw shaft rotating tool assists a rotating shaft to rotate, the rotating track of the rotating shaft cannot be limited and monitored, the following scheme is provided, the screw shaft rotating tool comprises two rotating shells arranged on the outer wall of the rotating shaft, and ball grooves are formed in the inner walls of the rotating shells; a ball groove is formed in the rotating shell, a plurality of balls are connected into the ball groove in a rolling mode, the outer walls of the balls are rotationally connected with the same inner ring, a waterproof pad groove is formed in the inner wall of the rotating shell, two waterproof pads are fixedly connected to the inner wall of the waterproof pad groove, and the two waterproof pads are located on the two sides of the inner ring; in the rotating process of the rotating shaft, the rotating track of the rotating shaft can be limited and monitored, the rotating shaft can be matched with the waterproof pad, seawater is prevented from entering a water body along the outer wall of the rotating shaft, meanwhile, friction force in the rotating process of the rotating shaft is reduced through cooperation of the balls, and the following process is smoother.

    本发明公开了一种艉轴转动工装,针对现有的艉轴转动工装辅助转轴转动时不能对转轴转动轨迹进行限位和监测的问题,现提出如下方案,其包括设置在转轴外壁的两个转动外壳,所述转动外壳的内壁设有滚珠槽,所述滚珠槽内滚动连接有多个滚珠,多个所述滚珠的外壁转动连接有同一个内环,所述转动外壳的内壁设有防水垫槽,所述防水垫槽的内壁固定连接有两个防水垫,且两个防水垫位于内环的两侧,本发明在转轴转动过程中可以对转轴转动的轨迹进行限位,进行监测,也能和防水垫之间进行配合,防止海水顺着转轴的外壁进入到水体内,同时滚珠的配合降低转轴转动过程中的摩擦力,使顺着过程更顺畅。
