Rotor structure of closed type rotary compressor

Abstract

The invention discloses a rotor structure of a closed type rotary compressor. The rotor is formed by superposing a plurality of laminates, all laminates, except the first laminate located above a rotating shaft and forming the upmost end of the rotor, are circular ring-shaped, and the central circular holes of the circular ring-shaped laminates are superposed to form a space for installing the rotating shaft; the first laminate located above the rotating shaft and forming the upmost end of the rotor is circular disc-shaped, and the part of the first laminate, superposed with the central circular holes of the lower laminates, is provided with a plurality of through holes. The through holes of the first laminate are long and thin circular arc-shaped, and four through holes are formed along the annular edges of the central circular holes. Only the annular part of the first laminate located above the rotating shaft and forming the upmost end of the rotor is stamped off, the central part is not stamped off and plays the function of baffling oil, the discharge amount of refrigerating machine oil in the running process of the compressor is reduced, and the performance and the efficiency of the product are improved.

Description

technical field [0001] The invention relates to a hermetic rotary compressor, in particular to a rotor structure of the hermetic rotary compressor. Background technique [0002] Traditional hermetic rotary compressors such as figure 1 , 2 As shown, a motor part 20 is installed on the upper side of the airtight container 10 of the compressor 1, and a compressor part 30 is installed on the lower side at a certain distance from the motor part 20. The motor part 20 includes a stator 21 that generates magnetic force according to applied power; a rotor 22 that rotates due to a change in magnetic flux due to the magnetic force of the stator 21 ; The compressor unit 30 includes a cylinder 31 that compresses the sucked refrigerant and then discharges it; it is assembled and combined with the upper and lower parts of the cylinder 31 to form a compression chamber P in the cylinder; it is connected to the rotating shaft 23 and supports the upper part of the rotating shaft Bearing 32 ...

AI Technical Summary

Problems solved by technology

The top of the rotating shaft 23 directly communicates with the upper space, so the refrigerating machine oil is directly mixed with the refrigerant through the center of the rotor and discharged from the compressor through the middle hole of the rotating shaft. However, too much refrigerating machine oil will affect the performance of the compressor and cause many problems in the matching of the air conditioner.
