Example Embodiment

[0010] Refer to figure 1 , The guide shaft is a cylindrical structure, one end of the guide shaft is matched with the large bearing assembly surface of the stator main shaft and supported on the end surface of the inner ring of the large bearing, and the other end is matched with the small bearing assembly surface of the stator main shaft. In order to avoid deformation of the guide shaft, 2 to 3 reinforcement ribs are welded inside. In order to prevent the guide shaft from scratching the assembly surface of the stator spindle bearing, a guard plate 1 and a guard plate 2 are fixed on the mating surface of the guide shaft and the stator spindle. The guard plate is: 5-15 (preferably 8~ 12 pieces) about 4 to 5 mm thick, 40 to 60 mm wide brass plate or bonded polytetrafluoroethylene plate. In order to enable the sliding sleeve to enter the guide shaft smoothly, the end of the sliding sleeve on the guide shaft is made into a tapered structure of 80-100 mm.

Abstract

The invention provides a generator stator and rotor assembling method and a device, which uses a guiding axle and a sliding bush to achieve the assembly of the generator stator and rotor, and is characterized in that the sliding bush and the guiding axle are fixed on the rotor and the stator through a connecting piece respectively; the inner surface of the sliding bush is moved from the top down along the outer surface of the guiding axle, so that the rotor is assembled on the stator; the rotor and the stator are separated from the sliding bush and the guiding axle respectively. The device for realizing the method includes a guiding axle and a sliding bush. The generator stator and rotor assembly is more convenient, saves manpower, and the device has simple and practical structure, disassembly and transportation are convenient.

Description

technical field [0001] The invention relates to a generator stator and rotor assembly method and device Background technique [0002] The existing generator stator-rotor package device is mainly composed of a triangle hanger, a hand wheel, a screw lift, a support leg and the like. The rotor is suspended on a triangular hanger suspended by three steel wire ropes. When the hand wheel of the screw lift is manually shaken, the rotor descends slowly. Since the lengths of the three wire ropes cannot be exactly the same, and the diameter of the rotor is relatively large, this method of fitting will make the levelness of the rotor worse. During the assembly process, since the speed of the operator's operation cannot be completely consistent, the rotor will be tilted to varying degrees and even the surface of the stator will be scratched, which will make the stator and rotor assembly difficult and may even require rework and reassembly. Contents of the invention [0003] In order...
