The invention relates to a special tool for extracting and mounting the rotor of a generator. The tool includes a roller pin bearing device, a shaft end support bracket device, an arc-shaped transition connection device and a rotor extracting and mounting mechanism, wherein the roller pin bearing device and the shaft end support bracket device are assembled to the rotor extracting and mounting mechanism in a matched manner through the arc-shaped transition connection device. With the special tool for extracting and mounting the rotor of the generator of the invention adopted, the problem of high difficulty in generator rotor extracting and mounting can be solved; the rotor can be extracted out in a short time, and expected safe and quick rotor extracting and mounting work can be realized; maintenance efficiency can be improved; and a guarantee can be provided for long-period stable operation of the generator set.
Description
technical field [0001] The invention belongs to the field of machinery, and relates to a special extraction tool for generator maintenance, in particular to a special extraction tool for generator rotors. Background technique [0002] In the inspection and maintenance of domestic steam turbine units, the main difficulty is that the generator rotor is the most difficult to install. Because the stator of the generating set is inseparable as a whole, the generator is installed as a whole when the equipment is installed. After the steam turbine, gearbox and generator are all installed, it is very difficult to pump and install the generator rotor during maintenance. And if the movement deviation when pumping the rotor is greater than the maximum gap between the rotor and the stator, serious equipment damage accidents will be caused. Therefore, it is very necessary to consider designing and manufacturing a set of rotor extraction tools that can be adjusted in height and can be pu...
