Abstract
The utility model, which belongs to the generator field, discloses a modularized engine base for a wind driven generator. The modularized engine base mainly comprises an engine base sleeve fixed at a stator, a transmission-side bearing seat detachably fixed at one end of the engine base sleeve, and a non-transmission side bearing seat detachably fixed at the other end. Because of different stress properties of all components of the engine base of the motor, the engine base is modularized, so that the volume and the weight of the motor are reduced to some extent. Meanwhile, the whole rigidity of the motor is not influenced. According to the traditional processes, stator inserting coil operation is carried out, the stator is then sleeved thermally into the stator base, and welding is carried out finally; compared with the prior art, the provided modularized engine base has the advantages in the requirement of a lifting tool and a difficult degree of a welding operation and the like; and moreover, the provided engine base also has the obvious advantage in batch motor production.
Description
Technical field
The utility model belongs to electrical generator fields, is specifically related to a kind of modularization support for wind-driven generator.
Background technology
The aerogenerator stator support has significant impact to the performance of motor and wind-powered electricity generation unit.Design a weight is little, intensity is high, shock resistance is strong out frame and be the necessary guarantee that motor can the high efficient and reliable operation.
Traditional electric machine stand mainly is by transmission side end plate and former, non-transmission side end plate and the integrally welded case structures such as former, left side plate, footing piece and reinforcement, by with the support end plate end cap that closes and bearing being realized the support of rotor and the stator and rotor casing that forms a relative closure.Be 20102064391.9 " motor damping support " such as China Patent No., adopt the mode of welding rectangle reinforcement and angle stiffener, although solved to a certain extent the problem of support rigidity and vibrations, but the support of this kind version takes up space greatly, quality is large, material does not obtain effective and reasonable utilization, follow-up stator winding installation and lifting operation are also more loaded down with trivial details, are unfavorable for realizing the motor mass production.
Summary of the invention
The technical problems to be solved in the utility model is that existing support takes up space greatly, quality is large, and material does not obtain effective and reasonable utilization, and follow-up stator winding installation and lifting operation are also more loaded down with trivial details, is unfavorable for realizing the problem of motor mass production.
The technical solution of the utility model is: be used for the modularization support of wind-driven generator, it is characterized in that: it is mainly by being fixed on the engine base sleeve on the stator and detachably being fixed on the transmission side bearing pedestal of engine base sleeve one end and the non-transmission side bearing pedestal of the other end consists of.
Further, described engine base sleeve one end is fixed with the engine base sleeve end plate and is spirally connected by engine base sleeve end plate and non-transmission side bearing pedestal, stator is positioned at engine base sleeve and is welded and fixed with engine base sleeve, and described stator one end has stator pressing ring, and described stator pressing ring and transmission side bearing pedestal are spirally connected.
Further, described engine base sleeve is for to roll the cylindrical tube that is welded by steel plate, and it radially has ventilation hole.
Further, described transmission side bearing pedestal and non-transmission side bearing pedestal all mainly are made of bearing pedestal end plate, bearing pedestal former, gusset, base anchor, and bearing pedestal end plate and bearing pedestal former are parallel to each other and by link of boards, have centering ring on the bearing pedestal end plate.
The utility model compared with prior art has following advantage:
1, in the utility model, for the different stressed character in each position of electric machine stand, reasonably with its modularization, the volume and weight of motor is reduced to some extent, do not affect the integral rigidity of motor simultaneously.
2, in the utility model, support both sides end plate all is monoblock steel plate cutting, its rigidity is better than traditional end cap and puts together on structure on the support end face, and support both sides end face and bearing assemble are in same sagittal plane, and its rigidity quality has a direct impact motor oscillating.
3, in the utility model, after stator core segment and stage casing engine base sleeve can being assembled, carry out again stator winding installation and the work of VPI dipping lacquer, very sufficient operating space is just arranged during stator winding installation like this, and carry out first the stator winding installation operation and again its hot jacket is entered the last again operation of welding of out frame and compare with traditional, to the requirement of lifting device, all advantageous to the aspects such as complexity of welding operation, when the mass motor was produced, advantage was more obvious.
