The utility model adopts the following technical scheme:
the utility model is used for disassembling a generator bearing on a rotating shaft of a golden S50/750 wind generating set, the outer diameter of one side of the rotating shaft, which is far away from the wind generating set, is gradually reduced, the generator bearing comprises a bearing body, a bearing hole, a rear end cover and a plurality of threaded mounting holes, wherein the bearing hole is arranged in the middle of the bearing body and is sleeved on the rotating shaft, the rear end cover is fixedly arranged on the circumferential surface of the bearing body, the threaded mounting holes are arranged on the rear end cover, the bearing hole is in interference fit with the rotating shaft, the generator bearing also comprises a supporting plate, a supporting hole A, a plurality of supporting holes B, a plurality of screw rods, the screw rods are in threaded connection with the threaded mounting holes and are sleeved on the inner sides of the supporting holes B, and nuts are in threaded connection with the screw rods and are in contact with the left side of the supporting plate, the aperture of the supporting hole A is smaller than the aperture of the bearing hole and larger than the outer diameter of the leftmost end of the rotating shaft, the distance between the threaded mounting hole and the axis of the rotating shaft is equal to the distance between the support hole B and the axis of the rotating shaft.
A spring pad is arranged between the left side surface of the support disc and the nut.
The utility model has the following positive effects:
1. the support hole A can clamp the support plate on the rotating shaft on the left side of the bearing body, the nut is screwed, the screw rod can move leftwards on the inner side of the support hole B to drive the rear end cover to move leftwards, and the generator bearing can be detached as the outer diameter of the rotating shaft on the side far away from the wind generating set is gradually reduced.
2. The spring washer can prevent the damage of the nut and the support plate.

FIG. 4 is a schematic view of the structure of the bearing body of the present invention.
In the drawings: 1. a rotating shaft; 2. a generator bearing; 3. a bearing body; 4. a bearing bore; 5. a rear end cap; 6. a threaded mounting hole; 7. a support disc; 8. a support hole A; 9. a support hole B; 10. a screw; 11. a nut; 12. a spring pad.
Detailed Description
As shown in the attached figures 1-4, the utility model comprises the disassembly of a generator bearing 2 on a rotating shaft 1 of a golden wind S50/750 wind generating set, the outer diameter of one side of the rotating shaft 1 far away from the wind generating set is gradually reduced, the generator bearing 2 comprises a bearing body 3, a bearing hole 4 which is arranged in the middle of the bearing body 3 and is sleeved on the rotating shaft 1, a rear end cover 5 which is fixedly arranged on the circumferential surface of the bearing body 3, a plurality of thread mounting holes 6 which are arranged on the rear end cover 5, the bearing hole 4 is in interference fit with the rotating shaft 1, a supporting plate 7 which is arranged on the left side of the bearing body 3, a supporting hole A8 which is arranged in the middle of the supporting plate 7 and is sleeved on the rotating shaft 1, a plurality of supporting holes B9 which are arranged on the side surface of the supporting plate 7, a plurality of screw rods 10 which are in threaded connection with the thread mounting holes 6 and are sleeved on the inner side of the supporting holes B9, and nuts 11 which are in threaded connection with the screw rods 10 and are in contact with the left side surface of the supporting plate 7, the diameter of the supporting hole A8 is smaller than that of the bearing hole 4 and larger than the outer diameter of the leftmost end of the rotating shaft 1, and the distance between the threaded mounting hole 6 and the axis of the rotating shaft 1 is equal to the distance between the supporting hole B9 and the axis of the rotating shaft 1. The support hole A8 can clamp the support disc 7 on the rotating shaft 1 on the left side of the bearing body 3, the nut 11 is screwed, the screw 10 can move leftwards on the inner side of the support hole B9, the rear end cover 5 is driven to move leftwards, and the generator bearing 2 can be detached as the outer diameter of one side of the rotating shaft 1, which is far away from the wind generating set, is gradually reduced.
A spring pad 12 is arranged between the left side surface of the supporting plate 7 and the nut 11. The spring washer 12 prevents damage to the nut 11 and the support disk 7.
