    摘要： The tool is designed to carried out maintenance operations on a bearing assembly comprising a bushing split into at least two shells; the maintenance tool comprises a device arranged to act on and rotate the bushing shells. In particular, the device comprises a slide and a pin; the slide has a hole transversal to its sliding direction and the pin is slidably mounted inside the hole and protrudes from the hole; in a first operating position the pin acts on a shell and in a second operating position the pin does not act on any shell. The method provides to rotate the bushing shells without rotating the supported shaft, and to carry out maintenance operations on a shell at a time while leaving the shaft supported by the other shell.

    摘要翻译： 该工具被设计成对包括分成至少两个壳体的衬套的轴承组件执行维护操作; 所述维护工具包括布置成作用于所述衬套壳体并旋转所述衬套壳体的装置。 具体地，该装置包括滑动件和销; 滑块具有横向于其滑动方向的孔，并且销可滑动地安装在孔内并从孔突出; 在第一操作位置，销作用在壳体上，并且在第二操作位置，销不会作用在任何壳体上。 该方法提供了在不旋转支撑轴的情况下旋转衬套壳体，并且一边离开由另一壳体支撑的轴线一次一边对壳体进行维护操作。
