Generator rotor jacking assembly and methods of use

摘要

A generator rotor jacking assembly includes a saddle secured to a generator end shield in the place of an outer oil deflector removed from the end shield. A yoke is located above the saddle and underlies the rotor end. Fluid-actuated cylinders are interposed between anvils on the saddle and flanges on the yoke to elevate the rotor end from the bearing, relieving the bearing from the weight of the rotor. A sling is then disposed about the rotor to support the rotor in an elevated position. The lower end shield is then lowered, carrying with it the associated parts for repair and maintenance.
