In the present embodiment, the size of outer shroud 21 and internal ring 22 does not limits, and can design according to demand.But, internal ring 22 interior
Footpath needs consistent with diameter of a circle outside motor 3 end, fixing motor 3 that just can be reliable and stable, effectively prevents from fixing motor 3 rear motor
3 arbitrarily rock between the internal ring 22 of two collars 2, it is to avoid the abrasion of motor 3, extend the service life of motor 3.
Concrete, the internal ring 22 of each collar 2 is inwardly projecting is provided with the annular stop boss 25 that a circle is complete, along the collar
2 axial, the height of positive stop lug boss 25 is less than the height of internal ring 22.Further, the outer face of positive stop lug boss 25 and internal ring 22
Outer face at same plane, the inner face of positive stop lug boss 25 is arranged less than the inner face of internal ring 22.It is to say, positive stop lug boss
Form ledge structure between 25 and internal ring 22, motor 3 is fixed.After assembling motor 3, the two ends of motor 3 are respectively
It is resisted against on the medial surface of positive stop lug boss 25 of two collars 2.Along the radial direction of the collar 2, the thickness of positive stop lug boss 25 does not limits, it is possible to
Fixing motor 3.
The collar 2 of the present embodiment uses aluminum alloy materials to be once molded, simple and reliable for structure, lighter in weight, installs
Convenient, structural strength is high.
The motor 3 of the present embodiment is specific as follows with the assembling process of housing 1:
First one of them collar 2 is inlaid in housing 1, and is welded on housing 1 in the way of being perpendicular to housing 1 inwall
On inwall, then motor 3 is inlaid on the positive stop lug boss 25 of housing 1 this collar 2 interior, afterwards another collar 2 is inlaid in
In housing 1, making motor 3 be clamped between the positive stop lug boss 25 of two collars 1, two collars 2 are welded on abreast the most at last
On housing 1 inwall, thus realize the assembling of compressor electric motor 3 and housing 1.
The application eliminates the hot jacket operation of motor 3 and housing 1, solves the stress problem of hot jacket assembling, decreases electricity
Machine 3 deformation, improves manufacturability, increases the flow area of compressor simultaneously, enhances ventilation effect, reduces motor 3 and transports
Temperature rise during row, improves the performance of motor 3, further, since the existence of the collar 2, motor 3 need not do so big, also
Save the usage amount of stalloy, reduce the iron loss of motor 3, reduce the production cost of motor 3.
