As such scheme preferably, totally four pairs of described double threaded screws, described hydraulic jack below is lined with planchet plate, described planchet plate covers the flange hole exposing on rotor center part.Select the paired double threaded screw of reasonable quantity, can ensure the reliability of installation, reduce costs simultaneously; Set up planchet plate, avoid hydraulic jack to fall into flange hole.
Installation process is as follows: first all double threaded screws, kidney-shaped plate, backing plate, nut are in place, distance between kidney-shaped plate and backing plate is greater than the distance of the flange upper surface of rotor center part and the flange lower surface of generator's motor shaft, mention backing plate and make gapless between the kidney-shaped plate of paired double threaded screw bottom and nut and the flange of generator's motor shaft, place again hydraulic jack, and the nut of adjusting double threaded screw upper end makes backing plate compress the top of hydraulic jack and ensure that backing plate is in level.
The course of work is as follows: operation pressure oil pump is worked many hydraulic jack simultaneously, by backing plate and double threaded screw, generator's motor shaft is promoted equably, rotor shaft link bolt is installed equably in the flange hole of rotor center part and generator's motor shaft, when promoting, generator's motor shaft tightens rotor shaft coupling nut, make the flange docking stably symmetrically of rotor center part and generator's motor shaft, afterwards by hydraulic jack, double threaded screw, kidney-shaped plate, the dismountings such as backing plate, remaining rotor shaft link bolt and rotor shaft coupling nut are installed, on request rotor shaft link bolt is stretched symmetrically and evenly, tighten rotor shaft coupling nut simultaneously, completed the work of generator amature shaft coupling.
The utility model works many hydraulic jack by operation pressure oil pump simultaneously, utilizes backing plate and double threaded screw that generator's motor shaft is promoted equably, makes the flange docking reposefully symmetrically of rotor center part and generator's motor shaft.Can ensure the lifting of generator's motor shaft equalization stable, avoid rotor center part and generator's motor shaft run-off the straight and shaft coupling docking dislocation, also avoided the damage of shaft link bolt, improved the operating efficiency of generator shaft coupling, reduction personnel working strength, has improved the fail safe of rotor shaft coupling work.
