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
The present invention relates to closed rotary compressor, especially the rotor structure of closed rotary compressor.
Background technique
Traditional closed rotary compressor as shown in Figure 1, 2, is provided with motor part 20 at the upside of seal container 10 inside of compressor 1, is keeping at a certain distance away with motor part 20, near downside, compressor section 30 is installed.Motor part 20 comprises according to the stator 21 of the power generation magnetic force applying; Because the magnetic force of stator 21 forms the rotor 22 that the variation of magnetic flux is rotated, be pressed into the running shaft 23 that is fixed on rotor 22 center and transmits rotating force.Compressor section 30 comprises the cylinder 31 that the refrigerant of suction is compressed to discharge afterwards and arrange; Be assembled in the top and the bottom of cylinder 31, and in cylinder, form pressing chamber P; Be connected with running shaft 23 respectively, and the upper bearing 32 of supporting rotating shaft and lower bearing 33.
In the pressing chamber P inner side of cylinder 31, be provided with the eccentric cam 24 with eccentric part with the eccentric certain distance in running shaft 23Zhou center.Contact inserts on the outer circumferential face of eccentric cam 24, and the annular piston 34 that revolves round the sun of the rotating force transmitting according to eccentric cam 24.
In figure, the 26, the 27th, the bearing fixture of running shaft, the 42nd, the refrigerant tap hole of upper bearing, the 43rd, exhaust valve assembly, the 44th, baffler, the 45th, refrigerant suction pipe, the 46th, refrigerant discharge tube.
Traditional closed rotary compressor of said structure, when applying power supply to motor part 20, the magnetic flux between stator 21 and rotor 22 will produce driving force, and driving force is fixed on rotor 22 running shaft 23 by being pressed into transmits; Eccentric cam 24 is formed on the inside of the cylinder 31 of running shaft 23, in the outer axial face of eccentric cam, Intercalation has annular piston 34, ring turns piston 34 with outer axial face together motion continuously, when annular piston 34 and baffle plate (not shown) be in the state that is in contact with one another it, annular piston will revolve round the sun in the inner space of cylinder 31 centered by eccentric cam.
The inner space of pressing chamber is to consist of the inner peripheral surface of cylinder pressing chamber P and the outer circumferential face of annular piston 34, by the revolution of annular piston 34, there is Volume Changes in pressing chamber inner space, this Volume Changes causes the refrigerant of high-temperature high-pressure state by inlet hole 40, to be inhaled into the inner space of inlet casing, is compressed into high-temperature high-pressure state.
As shown in Figure 3,4, the rotor 22 of the closed rotary compressor of prior art is superposeed and is formed by multiple laminations 38, and the lamination 38 of prior art is circular, and middle circular hole 28 stacks form the space that running shaft 23 is installed.The top of running shaft 23 directly communicates with upper space, so refrigerator oil directly mixes with refrigerant by rotor center and discharges compressor from running shaft mesopore, but refrigerator oil can affect compressor performance after discharging too much, causes air conditioner for matching to occur a lot of problems.
Summary of the invention
Technical problem to be solved by this invention is: a kind of rotor structure that reduces compressor closed rotary compressor of the discharge-amount of refrigerator oil in operation process is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of rotor structure of closed rotary compressor, rotor is superposeed and is formed by multiple laminations, except being positioned at the first lamination running shaft top, that form rotor the top, other lamination is circular, and the middle circular hole stack of circular lamination forms the space that running shaft is installed; Be positioned at running shaft top, to form rotor the first lamination be topmost discoid, with below the overlapping part of the middle circular hole of circular lamination be formed with multiple through holes.
The through hole of the first described lamination forms along the middle circle hole ring edge of circular lamination.
The through hole of the first described lamination is elongated circular-arc, along ring edge one circle of the middle circular hole of circular lamination, forms four.
The ring edge of circular hole in the middle of described four through hole Equal round ring-type laminations.
The invention has the beneficial effects as follows: be positioned at the first lamination punching press running shaft top, that form rotor the top and fall annular portion, intermediate portion is not had punching press to fall, play the oily effect of gear, reduce the discharge-amount of compressor refrigerator oil in operation process, improve performance and the efficiency of product.

Embodiment
Below in conjunction with the drawings and specific embodiments, the rotor structure of closed rotary compressor of the present invention is described in further detail:
The working principle of closed rotary compressor of the present invention is identical with prior art, can be with reference to prior art, thus no longer narration, and with reference to the reference character of prior art, the present invention is that rotor structure is different from the difference of prior art, is described in detail below:
As Fig. 3, 5, shown in 6, the rotor structure of closed rotary compressor of the present invention, rotor 22 is superposeed and is formed by multiple laminations, except being positioned at running shaft 23 tops, form outside rotor 22 the first lamination 7 topmost, other lamination 38 is circular, middle circular hole 28 stacks of circular lamination 38 form the space that running shaft 23 is installed, that is to say same as the prior art, be positioned at running shaft 23 tops, it is discoid forming rotor 22 the first lamination 7 topmost, with below the overlapping part of the middle circular hole 28 of circular lamination 38 be formed with multiple through holes 8.
The through hole 8 of the first described lamination 7 is elongated circular-arc, along ring edge one circle of the middle circular hole 28 of circular lamination 38, forms four.Four through hole 8 grades are divided the ring edge of the middle circular hole 28 of lamination 38.
The present invention falls annular portion by rotor 22 7 punching presses of the first lamination topmost, and intermediate portion does not have punching press to fall, and forms as Fig. 5 structure.The part not being stamped by the first lamination 1 center from running shaft 23 mesopores refrigerator oil is out blocked, and discharges compressor after avoiding mixing with refrigerant, and the oil having reduced in compressor operation process spues.
In sum, in the embodiment that content of the present invention is not confined to, the knowledgeable people in same area can propose easily other embodiment within technological guidance's thought of the present invention, but this embodiment comprises within the scope of the present invention.
