Abstract
The invention relates to a rotary compressor structure with an uniform stator and rotor clearance, which comprises a cover of an upper casing, a stator, a rotor, a crankshaft, a casing body, an upper cylinder cover, a cylinder, a piston, a lower cylinder cover, a cover of a lower casing and an air inlet connecting pipe; the upper cylinder cover and the casing body combine two into one, and enable one shot forming to an one-piece frame, an inner concave platform is provided at the top of the one-piece frame, an inner concave platform plane is provided with the inner concave platform, the lower part of the stator is fixed on the inner concave platform plane. Compared with the prior art, the rotary compressor structure has the advantages of uniform stator and rotor clearance, good coaxiality between coaxial parts and the like.
Description
Technical field
The present invention relates to rotor-type compressor, especially relate to the rotor-type compressor structure of rotor gap uniformity.
Background technique
Present rotor-type compressor is when installing stator, and need heated shell, carry out hot jacket, the stator after hot jacket and housing, the coaxality of the pump housing not easily ensures, thus the performance of compressor can be made to be subject to certain impact, makes the work efficiency drop of this compressor.In addition, common rotor compressor is mostly cylinder or the common welding of upper cylinder cover, and the heat of welding causes thermal distortion, also has a certain impact to the coaxality of compressor, causes the gap between rotor not to be very even.
Summary of the invention
Object of the present invention is exactly provide the rotor-type compressor structure of the rotor gap uniformity that coaxality between a kind of coaxial elements is good to overcome defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions: the rotor-type compressor structure of rotor gap uniformity, comprise upper casing cover cap, stator, rotor, bent axle, housing, upper cylinder cover, cylinder, piston, lower cylinder cap, lower casing cover cap, inlet pipe connection, it is characterized in that, described upper cylinder cover and housing unite two into one, and once-through is integrated open frame, the top of this integral type frame is provided with concave station in, this interior concave station is provided with concave station plane in, and the lower end of described stator is fixed in interior concave station plane.
Described stator is fixedly connected with by viscose glue or bolt with interior concave station plane.
Described integral type frame is by casting once-through.
Described integral type frame is formed by metal material processing.
Described metallic material is cast iron.
The top of described integral type frame is connected with upper casing cover cap.
The bottom of described integral type frame is connected with lower casing cover cap.
Described integral type frame and upper casing cover cap, lower casing cover cap are by weld or viscose glue is connected.
Compared with prior art, synthesis parts are directly cast or processed to housing and upper cylinder cover by the present invention, and on the compressor cylinder cap processes a platform (interior concave station plane), stator is arranged on this platform, after good solution compressor assembling, the problem that stator and housing, upper cylinder cover coaxality are bad, solves the problem that rotor gap is uneven simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein, 1-upper casing cover cap, 2-stator, 3-rotor, 4-bent axle, 5-integral type frame, 6-cylinder, 7-piston, cylinder cap under 8-, 9-lower casing cover cap, 10-inlet pipe connection, concave station in 11-, concave station plane in 111-.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Figure 1, the rotor-type compressor structure of rotor gap uniformity, comprise upper casing cover cap 1, stator 2, rotor 3, bent axle 4, integral type frame 5, cylinder 6, piston 7, lower cylinder cap 8, lower casing cover cap 9, inlet pipe connection 10, integral type frame 5 is by metallic material, and such as cast iron (FC250) is by casting once-through.By laser bonding, the top of integral type frame 5 and upper casing cover cap 1 are connected and fixed, bottom and lower casing cover cap 9 are connected and fixed, the top of this integral type frame 5 is provided with concave station 11 in, this interior concave station 11 is provided with concave station plane 111 in, and the lower end of stator 2 is bolted to connection in interior concave station plane 111.
Owing to processing integrated with housing for upper cylinder cover, unite two into one integral open frame 5, and concave station plane 111 in is processed in this integral type frame 5, stator is directly installed in interior concave station plane 111, use adhesive is fixed, stator is arranged on this step-like platform, can it be effectively stoped to move radially, stator is located, thus the problem of coaxality between upper cylinder cover and stator can be ensured well, avoid hot jacket high temperature to produce the impact of thermal distortion to stator, also have good guarantee to the gap between rotor.
Embodiment 2
See Fig. 1, the rotor-type compressor structure of rotor gap uniformity, wherein, top and the upper casing cover cap 1 of integral type frame 5 are connected and fixed by viscose glue, its underpart and lower casing cover cap 9 viscose glue are connected and fixed, the lower end viscose glue of stator 2 is fastened in interior concave station plane 111, and all the other structures are identical with embodiment 1.
