Abstract
The utility model discloses a stator rib structure of a stator core in a square box machine base. The stator rib structure comprises a stator rib body and bosses fixed on the stator rib body. The stator rib body is a U-steel, which is cut according to requirements for acquiring a required length; two ends of the bottom of the U-steel are welded with thin steel plates, which serve as the bosses matched with a machine base; and the stator rib body is provided with a plurality of vent holes, which are disposed in the bottom of the U-steel. Compared with a conventional stator rib structure, the stator rib structure of the stator core in the square box machine base realizes production cycle shortened by a quarter, U-steel weight reduced by two thirds compared with a conventional stator rib cut from a whole steel plate, material cost reduced by a quarter, and motor temperature rise reduced by 5-8 K.
Description
Technical field
The utility model relates to a kind of stator core, especially relates to the stator muscle structure of stator core in a kind of square chest support.
Background technology
See also Figure 1 and Figure 2, at present, stator muscle great majority in the domestic square chest support in the stator core are to adopt monoblock steel plate 10 to cut into strip, the two ends of steel plate 10 are fixed with the boss 11 that cooperates support, be welded on the outer surface of stator punching then, because whole piece steel plate 10 is welded on the stator core outer surface, this structure can cause that the part air duct is plugged, the motor internal wind path is inhomogeneous, the motor internal wind path reduces, finally cause electric machine temperature rise higher, influence the overall performance of motor, and this stator muscle is heavy, and material is wasteful, the cost height.
The utility model content
Technical problem to be solved in the utility model is to provide the stator muscle structure of stator core in a kind of square chest support, and this structure makes the air duct aeration flow normal, and the motor internal wind path is even, and electric machine temperature rise reduces, and the cost of material is low.
The purpose of this utility model is to be achieved through the following technical solutions:
The stator muscle structure of stator core in a kind of square chest support, it comprise stator muscle body and and be fixed in boss on the stator muscle body, wherein, offer several ventilation holes on the described stator muscle body.
Especially, described stator muscle body is a channel-section steel, offers several ventilation holes on the channel-section steel bottom surface.
Especially, described boss is the sheet metal that is welded on the channel-section steel.
Especially, described ventilation hole is circular, square and oval-shaped any or several combining.
The beneficial effects of the utility model are, the stator muscle structure of stator core uses channel-section steel as stator muscle body in the described square chest support, and on channel-section steel, offer several ventilation holes, compare with traditional stator muscle structure, make production efficiency shorten 1/4th, channel-section steel is with respect to the stator muscle of former whole piece steel plate cutting, and weight has lacked 2/3rds, material cost has saved 1/4th, and 5-8K has fallen in electric machine temperature rise.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the profile of traditional square chest steel plate support;
Fig. 2 is the vertical view of the stator muscle structure of stator core in the utility model square chest support;
Fig. 3 is the profile of the stator muscle structure of stator core in the utility model square chest support;
Fig. 4 is the vertical view of the stator muscle structure of stator core in the utility model square chest support.
Embodiment
Please refer to Fig. 3 and shown in Figure 4, Fig. 3 is the profile of the stator muscle structure of stator core in the utility model square chest support; Fig. 4 is the vertical view of the stator muscle structure of stator core in the utility model square chest support.
In the described square chest support stator muscle structure of stator core comprise it comprise stator muscle body 20 and and be fixed in boss 21 on the stator muscle body 20, in present embodiment, described stator muscle body 20 is for blocking out the channel-section steel of Len req as required, the two ends, bottom surface of described channel-section steel are welded with sheet metal, described sheet metal is as the boss 21 that cooperates support, and offer several ventilation holes 22 on the described stator muscle body 20, in present embodiment, described ventilation hole 22 is opened on the channel-section steel bottom surface, and it is a circular configuration.
The stator muscle structure of stator core uses channel-section steel as stator muscle body in the above-mentioned square chest support, and on channel-section steel, offer several ventilation holes, compare with traditional stator muscle structure, make production efficiency shorten 1/4th, channel-section steel is with respect to the stator muscle of former whole piece steel plate cutting, weight has lacked 2/3rds, and material cost has saved 1/4th, and 5-8K has fallen in electric machine temperature rise.
