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 uniform rotor-type compressor structure in rotor gap.
Background technique
Present rotor-type compressor needs heated shell when stator is installed, carry out hot jacket, stator behind the hot jacket and housing, and the coaxality of the pump housing is difficult for assurance, thereby can make the performance of compressor receive certain influence, makes the working efficiency of this compressor descend.In addition, common rotor compressor is the common welding of cylinder or upper cylinder cover mostly, and the heat of welding causes thermal distortion, and the coaxality of compressor is also had certain influence, and causing the gap between the rotor is not very evenly.
Summary of the invention
The object of the invention is exactly to provide the rotor gap that coaxality is good between a kind of coaxial elements uniform rotor-type compressor structure for the defective that overcomes above-mentioned existing technology existence.
The object of the invention can be realized through following technological scheme: the uniform rotor-type compressor structure in rotor gap; Comprise upper casing cover cap, stator, rotor, bent axle, housing, upper cylinder cover, cylinder, piston, following 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 the integral type frame, and the top of this integral type frame is provided with concave station in; Should be provided with concave station plane in by interior concave station, the lower end of described stator is fixed on the interior concave station plane.
Described stator is connected through viscose glue or bolt with interior concave station plane.
Described integral type frame is through the casting once-through.
Described integral type frame is to be formed by metal material processing.
Described metallic material is a cast iron.
The top of described integral type frame is connected with the upper casing cover cap.
The bottom of described integral type frame is connected with the lower casing cover cap.
Described integral type frame is connected through welding or viscose glue with upper casing cover cap, lower casing cover cap.
Compared with prior art; The present invention directly casts or processes synthetic parts with housing and upper cylinder cover; And on the compressor upper cylinder cover processing one platform (interior concave station plane), stator is installed on this platform, well solve compressor assembling after; Stator and housing, the bad problem of upper cylinder cover coaxality have solved the uneven problem in rotor gap simultaneously.
Description of drawings
Fig. 1 is a 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 the 8-, 9-lower casing cover cap, concave station plane in the concave station in the 10-inlet pipe connection, 11-, 111-.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
As shown in Figure 1; The uniform rotor-type compressor structure in rotor gap; Comprise upper casing cover cap 1, stator 2, rotor 3, bent axle 4, integral type frame 5, cylinder 6, piston 7, following cylinder cap 8, lower casing cover cap 9, inlet pipe connection 10; Integral type frame 5 is by metallic material, and for example cast iron (FC250) is through the casting once-through.The top of integral type frame 5 is connected fixing with upper casing cover cap 1 through laser bonding; The bottom is connected fixing with lower casing cover cap 9; The top of this integral type frame 5 is provided with concave station 11 in; Should be provided with concave station plane 111 in by interior concave station 11, the lower end of stator 2 is connected on the interior concave station plane 111 through bolt.
Because with upper cylinder cover and the integrated processing of housing, uniting two into one is integral open frame 5, and on this integral type frame 5, process concave station plane 111 in; Stator is directly installed on the interior concave station plane 111; Use adhesive to fix, stator is installed on this step-like platform, can effectively stop it to move radially; Make the stator location; Thereby can guarantee the problem of coaxality between upper cylinder cover and the stator well, avoid of the influence of hot jacket high temperature, also there is good assurance in the gap between the rotor stator generation thermal distortion.
Referring to Fig. 1; The uniform rotor-type compressor structure in rotor gap; Wherein, the top of integral type frame 5 is connected through viscose glue with upper casing cover cap 1 to be fixed, and its underpart is connected fixing with lower casing cover cap 9 viscose glues; On the concave station plane 111, all the other structures were identical with embodiment 1 in the lower end viscose glue of stator 2 was fastened on.
