Disk, sleeve and lower reinforcing rib being integrated cast aluminum construction, the external shell and upper being integrated of reinforcing rib cast aluminum construction.
Wherein, an annular space is provided between the external shell and sleeve, the lower reinforcing rib and upper reinforcing rib are equal
In annular space.
Wherein, external shell both ends end face is respectively arranged with annular convex platform.
Wherein, the one end of the external shell far from ring flange is provided with positioning end cap.
Wherein, the positioning end cap inner side end be disposed with outward using to position end cap central as the center of circle annular protrusion with
Annular positioning groove, the end face of the annular protrusion is squeezed with sleeve end face to be positioned.
Wherein, setting is evenly arranged with through-hole on the external shell.
Wherein, the ring flange outer end face and positioning end cap outer end face are respectively arranged with matched with respective annular convex platform
Connect bolt.
The beneficial effects of the utility model：A kind of lightweight assembling motor housing, using separate structure, assembly and disassembly are fast
Victory is locked using groove and boss positioning and then by bolt, external shell and inner shell can be dismantled and individually be tieed up
Shield is replaced, and light-weight, maintenance cost is low, reduces use cost.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The technical solution of the utility model is further illustrated with reference to Fig. 1 and by specific embodiment.
A kind of lightweight assembling motor housing, including：Inner shell 1 and external shell 2, the inner shell 1 are set with one heart
It puts in external shell 2, the inner shell 1 includes ring flange 11 and sleeve 12, and the sleeve 12 is arranged concentrically on ring flange
11 sides, the end face indent that the ring flange 11 is located at sleeve are provided with annular groove 13, and 12 outer circle of sleeve is evenly equipped with
The lower reinforcing rib 14 in 12 outside of sleeve is directed toward, the lower Positioning holes in 12 outer circle of sleeve are provided between the lower reinforcing rib 14
15,2 inner wall even distribution of external shell have with lower 14 corresponding upper Positioning holes 21 of reinforcing rib, set between the upper Positioning holes 21
There are upper reinforcing rib 22 corresponding with lower Positioning holes 15,14 being integrated cast aluminium knot of the ring flange 11, sleeve 12 and lower reinforcing rib
Structure, 22 being integrated cast aluminum construction of the external shell 2 and upper reinforcing rib, lower reinforcing rib 14 and external shell 12 on sleeve 12
On upper reinforcing rib 22 mutually support, form booster action, not only reduced housing gross mass, but also increase the intensity of electric machine casing, outside
Portion's housing 2 and inner shell 1, which can be dismantled, to be separately maintained or is replaced, and maintenance cost is low, reduces use cost.
