In an embodiment, described bent axle is sleeved in the inner circle of described rotor therein.
In an embodiment, the end face of described rotor is provided with circular groove therein, and described magnet ring is arranged in described circular groove.
In an embodiment, between the circular groove of described rotor and described magnet ring, be interference fit therein.
In an embodiment, described magnet ring is bonded in the circular groove of described rotor by viscose therein.
In an embodiment, described upper flange is flat therein, and and the end face of described cylinder and the outer side wall of described magnet ring between form confined space.
In an embodiment, described electric machine assembly is disk permanent-magnet dc motor therein.
Therein in an embodiment, described stator is arranged in described housing by hot jacket or the mode of colding pressing.
In an embodiment, described pump assembly is fixed in described housing by three spot welding or six spot welding therein.
The rolling rotor type compressor that the utility model provides, electric machine assembly and pump assembly are designed to integrated form, the rotor that is about to motor is assembled to pump assembly inside, and rotor has replaced the roller in traditional compressor, has realized integrated in rotor and roller function; Thereby greatly reduce the axial dimension of compressor, make that compressor weight is light, volume is little, compact structure, being specially adapted to small-sized or microminiature refrigeration system etc. has the occasion of strict restriction for installing space.
Accompanying drawing explanation
Fig. 1 is the complete machine sectional view of the utility model rolling rotor type compressor;
Fig. 2 is the plan view of the part-structure of compressor shown in Fig. 1;
Fig. 3 is that the A-A of the part-structure of compressor shown in Fig. 2 is to view.
Embodiment
Referring to Fig. 1 to Fig. 3, the utility model provides a kind of rolling rotor type compressor, comprise electric machine assembly 100, pump assembly 200 and housing 300, electric machine assembly 100 comprises stator 110, rotor 120 and magnet ring 130, pump assembly 200 comprises cylinder 210, bent axle 220, slide plate 230, upper flange 240 and lower flange 250, stator 110 is positioned at the top of described cylinder 210 and is arranged on housing 300, and rotor 120 is arranged on the inside of cylinder 210, and magnet ring 130 is fixing with rotor 120; Slide plate 230 is arranged on the sidewall of cylinder 210 and contacts with the outer side wall of rotor 120.Upper flange 240 and lower flange 250 are arranged on the both sides of cylinder 210, for fixing cylinder; The outer side wall 122 of rotor 120 forms with the madial wall of cylinder 210 212 sealed cavity 400 that a position constantly changes, and reciprocating slide plate 230 is divided into two-part by sealed cavity.Preferably, sealed cavity 400 is crescent shape, and refrigeration working medium is interior compressed at crescent shape sealed cavity 400.The compressor that the utility model provides, because rotor 120 is arranged on the inside of cylinder 210, greatly reduces the axial dimension of compressor, makes that compressor weight is light, volume is little, compact structure.
As a kind of embodiment, rotor 120 is eccentric structure, the inner circle of rotor 120 and cylinder 210 concentric fits.Eccentric rotor 120 has replaced roller of the prior art, and between cylinder, forms closed cavity, in order to compression refrigeration working medium.Preferably, bent axle 220 is sleeved in the inner circle of rotor 120, and this mode is assembled simply, direct driving crank when rotor rotates, and the while has effectively been utilized space, is conducive to the miniaturization of compressor.
As a kind of embodiment, electric machine assembly 100 is disk permanent-magnet dc motor, and stator 110 and rotor 120 are the axial reciprocity axial air-gap magnetic field that arranges and produce.Disk permanent-magnet dc motor volume is little, and quality is light, has saved space, has reduced the volume of compressor.
As a kind of embodiment, magnet ring 130 can be arranged on rotor 120 by circular groove 124, the circular groove 124 matching at end face setting and the magnet ring 130 of rotor 120, then magnet ring 130 is embedded wherein.This mode is easy to assembling, and has saved axial space, has reduced the axial dimension of compressor.For the mechanical robustness between reinforcing member, circular groove 124 can closely combine by interference fit with magnet ring 130.In addition, magnet ring 130 can also be bonded in the circular groove 124 of described rotor by viscose.
In an embodiment, for guaranteeing the sealing of compressor, upper flange 240 designs become slab construction therein.Between the outer side wall of the end face of this structure and cylinder 210 and magnet ring 130, form airtight space, effectively prevented the leakage of refrigeration working medium.
