[utility model content]
It is a kind of simple in structure, easy to process that the utility model provides, and assembling is reliable, can save the rotor of the rotary compressor of rotor turning processing.
In order to realize above-mentioned utility model object, the technical solution adopted in the utility model is:
The rotor of rotary compressor, this rotor is made up of the large-diameter rotor section in axial direction arranging and minor diameter rotor section, minor diameter rotor section and large-diameter rotor section are in axial direction setting up and down, and laminating of minor diameter rotor section concentric forms whole rotor in large-diameter rotor section; Described minor diameter rotor section and large-diameter rotor section Thickness Ratio are in the axial direction 1:4; Described minor diameter rotor section and the large-diameter rotor section that is superimposed on downside form the step of a circle.
Preferably, the direct concentric of multiple major diameter silicon steel sheets that described large-diameter rotor section is stamped to form by major diameter diel is overrided to form.
Preferably, the direct concentric of multiple minor diameter silicon steel sheets that described minor diameter rotor section is stamped to form by minor diameter diel is overrided to form.
Preferably, the monolateral clearance distance between the stator inner circle that the large-diameter rotor section cylindrical of described rotor is mated is not less than 0.5mm.
Preferably, the monolateral clearance distance between the stator inner circle that the minor diameter rotor section cylindrical of described rotor is mated is not less than 0.7mm.
The beneficial effects of the utility model are:
Rotary compressor motor rotor of the present utility model adopts the structure of two section type, is made up of the large and small diameter rotor section in axial direction arranging, and laminating of minor diameter rotor section concentric forms whole rotor in large-diameter rotor section, because the silicon steel sheet diameter of minor diameter rotor section is less than the silicon steel sheet diameter of large-diameter rotor section, and the Thickness Ratio of minor diameter rotor section and large-diameter rotor section is 1:4 in the axial direction, make minor diameter rotor section and the large-diameter rotor section that is superimposed on downside form the step of a circle, make the monolateral clearance distance between stator inner circle that minor diameter rotor section cylindrical is mated be greater than the monolateral gap that large-diameter rotor section forms, like this, when after bent axle after rotor hot jacket, can effectively avoid bent axle in the axial direction amount of deflection change the impact on rotor top, reserved step meets the hot jacket distortion needs of rotor, can make rotor directly be assemblied in motor stator, save existing rotor outer circle turning manufacturing procedure, save processing cost, assembly technology is effectively improved simultaneously, save the rotor machining time, assembling process environmental protection and improved production efficiency.
