Abstract
The invention discloses a replacing tool for a high-speed shaft bearing outer ring of a wind generating set gearbox. The replacing tool comprises a disc-shaped part, a guiding lead screw, a hollow jack, a supporting base and two supporting fixing lead screws. One end of the guiding lead screw is connected to a center hole of the disc-shaped part. The hollow jack is fixed to the guiding lead screw through a first gasket and a first nut. A threaded hole is formed in the center of the supporting base, and the guiding lead screw penetrates through the threaded hole. One end of each supporting fixing lead screw penetrates through a strip-shaped hole in the supporting base. The invention further discloses a method for installing and detaching the bearing outer ring by using the tool. The tool is used for solving the problem that the bearing outer ring is not easy to detach. The tool is easy to operate, the hollow jack is used, and therefore lots of manpower and material resources are saved. All the components of the tool are convenient to carry and easy to use in the process of maintaining a fan in air t.
