Description
Technical field
The utility model relates to a kind of electric big bus drive motors water-cooling structure, especially water cooling construction for shell cover.
Background technology
At present, driving motor for electric automobile cooling structure is generally on support and designs cooling-water duct, mainly concentrate on iron core part is carried out cooling, and cooling not to the most serious winding overhang part of heating; Simultaneously for electric bus drive motors, because its transmitting torque is large, not only larger to need water to carry out cooling for the loss of iron core part, also can not be ignored as the heating problem of main stressed member bearing simultaneously, but the mode that designs cooling water channel on traditional support can not meet the radiating requirements of bearing, if adopt special high temperature resistant bearing, the significantly rising of cost will be caused; In order to meet the cooling needs of winding overhang and bearing, at this, water cooling construction for shell cover is proposed.
Utility model content
The purpose of this utility model is to provide a kind of novel water cooling construction for shell cover, and this structure can realize cooling to winding overhang and bearing, thereby can realize the effective cooling of winding overhang and adopt plain bearing to reach the object that reduces motor holistic cost.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of electric big bus drive motors water cooling construction for shell cover, comprise end cap body and be located at the bearing pedestal on end cap body, described end cap body one side is provided with end cap water inlet and end cap delivery port, on described end cap body taking bearing pedestal as the center of circle, be provided with the first water annulus and the second water annulus, described the first water annulus and the second water annulus interval arrange, described end cap water inlet is the first dividing plate being oppositely arranged, second partition, the first dividing plate extends to bearing pedestal from end cap body one side, second partition extends to first water annulus one end from end cap body one side.
Described first water annulus one end connects second partition, and the other end is free end.
Described second water annulus one end connects the first dividing plate, and the other end is free end.
Described bearing pedestal is adjacent with the first water annulus.
Described the first water annulus and the second water annulus upper surface are lower than end cap body end face 5mm.
Described end cap body is provided with circular cover, and circular cover is located at annular opening place.
Described circular cover circumference has groove, and described circular cover thickness is 5mm.
The beneficial effects of the utility model: the utility model is by the first water annulus and second water annulus of end cap body, the heat of winding overhang and the generation of bearing place can be taken out of in time, thereby guarantee motor entirety is moved in reliable temperature range, and this motor end cap structure is simple, is easy to production and processing.
Brief description of the drawings
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the utility model end cap body schematic top plan view.
Fig. 2 is the utility model end view.
Embodiment
As Fig. 1, shown in Fig. 2, a kind of electric big bus drive motors water cooling construction for shell cover, comprise end cap body 5 and be located at the bearing pedestal 1 on end cap body 5, described end cap body 5 one sides are provided with end cap water inlet 2 and end cap delivery port 3, on described end cap body 5 taking bearing pedestal 1 as the center of circle, be provided with the first water annulus 9 and the second water annulus 10, described the first water annulus 9 and the second water annulus 10 intervals arrange, first dividing plate 7 of described end cap water inlet 2 for being oppositely arranged, second partition 8, the first dividing plate 7 extends to bearing pedestal 1 from end cap body 5 one sides, second partition 8 extends to first water annulus 9 one end from end cap body 5 one sides.Described first water annulus 9 one end connect second partition 8, and the other end is free end, is not connected with the first dividing plate 7.Described second water annulus 10 one end connect the first dividing plate 7, and the other end is free end, is not connected with second partition 8.Bearing pedestal 1 is adjacent with the first water annulus 9.Described the first water annulus 9 and the second water annulus 10 upper surfaces are lower than end cap body 5 end face 5mm.Described end cap body 5 is provided with circular cover 6, and circular cover 6 is located at annular opening 4 places.Described circular cover 6 circumferences have groove, and described circular cover 6 thickness are 5mm.
In Fig. 1, the first water annulus 9 and the second water annulus 10 form five water channels, and cooling water enters after end cap by direction shown in arrow in figure by end cap water inlet 2 places, and cooling water outwards flows from bearing pedestal 1, finally flow out from end cap delivery port 3, and be connected in support water pipe by 3.This structure can farthest be taken away the heat of winding overhang and the generation of bearing place in time, thereby ensures that motor moves in reliable temperature range.Circular cover 6 is located at annular opening 4 and can opens corresponding groove according to welding procedure and weld, and should ensure that commissure can ensure to bear 0.35Mpa hydraulic pressure 45min ne-leakage after welding.After having welded, just can and select bearing size to carry out the processing of corresponding size according to the concrete fit dimension of end cap, add the location conflicts that should prevent processing dimension and water channel man-hour.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendments to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, all should belong to protection range of the present utility model.
