Description

Generator rotor support

Technical Field

The utility model relates to the technical field of support, in particular to a generator rotor support structure.

Background

The generator rotor is the rotating part of the generator. The wind driven generator set mainly comprises a conductive rotor winding, a magnetic iron core, a rotor shaft extension, a guard ring, a center ring, a fan and the like, wherein the damage faults of a wind driven generator set bearing and the maintenance of a generator stator and a generator rotor are relatively high in unit maintenance, and the fixing mode and the method are adopted in the process of replacing the generator bearing and the motor stator and rotor maintenance of each unit manufacturer. During maintenance, the generator rotor is suspended, and because the replacement time is long, the bearing at the other end of the rotor bears the pressure and the torsion of the mass (more than 1 ton) of the rotor body, and the bearing is extremely easy to fatigue and damage; the rotor is also prone to friction and impact between the stator and rotor core during the descent process.

When the rotor is maintained, most of the rotors are placed on the ground, then maintenance personnel need to rotate the rotors in time to carry out maintenance work, and before a dummy shaft is installed, heavy sleepers are usually adopted as supporting pieces to support the generator rotors, so that movement and adjustment are difficult, a large amount of manpower resources are required to be consumed, and a generator rotor supporting structure is required to be provided.

Disclosure of Invention

The utility model aims to provide a generator rotor support to solve the technical problems that a generator rotor is not supported, the process hidden trouble exists in the process of replacing a generator bearing, and impacts are caused to gaps of a side bearing, a stator, a rotor iron core, a coil, a bearing, a fixed sleeve and the like.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the utility model provides a generator rotor support, wherein a shaft type structure is arranged at a right-angle side structure above a support base and is connected with a reverse rotation screw rod, a forward rotation screw rod is arranged right above the reverse rotation screw rod, an adjusting sleeve is arranged between the two screw rods, an adjusting hole is arranged in the middle of the adjusting sleeve, and a round support disc with a stable structure is welded at the tail end of the forward rotation screw rod. The reverse rotation screw rod and the shaft structure above the support are provided with a sleeving part. The middle of the reverse rotating screw rod and the forward rotating screw rod are connected by means of sleeve adjustment. The forward rotating screw rod and the support disc at the top of the support are of a welded integrated structure. When the rotor support works and rotates, the forward rotating screw rod and the reverse rotating screw rod below keep the original structure unchanged through forward and reverse rotation.

Based on the technical scheme, the embodiment of the utility model at least has the following technical effects:

(1) According to the generator rotor support provided by the utility model, the generator is generally in a narrow space, oil pipes and wiring are distributed near the rotor, and the large-scale tooling is not beneficial to maintenance and replacement.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The utility model provides a technical scheme that: the utility model provides a generator rotor support, includes support base 1, a counter-rotating screw rod 2 has been cup jointed to base 1 top, counter-rotating screw rod 2 top is connected with adjustment sleeve 3, and the sleeve center is provided with adjustment hole 5, adjustment sleeve 3 top is connected with a forward rotating screw rod 4, forward rotating screw rod 4 end is fixed with circular supporting disk.

The upper part of the support base 1 is designed into a right-angle structure, two inherent structures exist on the surface of the support base, and the support base is connected with the counter-rotating screw rod 2 to form a shaft type structure, so that the migration adjustment of the left end and the right end is facilitated.

The sleeving part of the reverse rotation screw rod 2 and the support base 1 is welded, so that the reverse rotation screw rod 2 is connected with the support base 1 in a T-shaped structure.

The reverse rotation screw rod 2 and the forward rotation screw rod 4 are connected with the adjusting sleeve 3 in a positive and negative rotation mode, and are fixed through corresponding relation adjustment and combining with an adjusting hole above the adjusting sleeve 3, so that the support rotor is stabilized, the adjustable range is 400-600mm, and the support rotor is suitable for units of different manufacturer types.
