Description
Technical field
The present invention relates to a kind of compressor.Particularly relate to and a kind ofly can avoid compressor leakage, thermal distortion, improve the body of compressor in compressor life-span and the fixed structure of housing.
Background technique
Usually compressor has following structure: the inside of compressor housing forms certain space; Press part is arranged on the inside of housing, by the refrigerant of compressing section compresses from the outside inflow of housing; Motor section is arranged on the top of press part, provides driving force by motor section to press part.
Fig. 1 is the compressor inner structure schematic representation of prior art.
As shown in Figure 1, the compressor of prior art its be to constitute by following structure: be provided with the motor section and the press part that constitute compressor block in the inside of compressor housing 4.
Motor section includes: the stator 3 of motor, rotor 2 and running shaft 1, and wherein, stator 3 constitutes concentric circle with rotor 2, and the outer circumferential face of the inner peripheral surface of stator 3 and rotor 2 keeps certain clearance; Running shaft 1 is pressed into the central part of rotor 2; Running shaft 1 lower end is formed with eccentric part, and eccentric part is arranged in the press part of absorption and compression refrigerant.
Press part is made of following structure: the circular cylinder 9 that is fixed on the inner peripheral surface of shell and connects with suction pipe; Combining closely connects the upper bearing 6 and the lower bearing 8 of running shaft 1 in the upper/lower terminal face of cylinder 9, be formed with the fixedly last axle journal 5 of running shaft 1 on its upper bearing 6; With running shaft 1 is the center, carries out simultaneously the ring that rolls that off-centre rotatablely moves in cylinder 9; And in cylinder, be formed with rolling when rotation ring and form the compression volume 18 of compression refrigerant gas with upper bearing 6, lower bearing 8.
After as above the closed rotary compressor that constitutes connected power supply, the rotor 2 of motor section drove the running shaft 1 that is pressed in rotor 2 and together rotates.Rotation along with running shaft 1, the eccentric part that running shaft 1 lower end forms and roll the ring rotation with eccentric part combines, to enter the cold media air that compression volume 18 interior low-temp low-pressure compressing refrigerant gas become High Temperature High Pressure through the suction port of cylinder 9, the cold media air of compressed High Temperature High Pressure is discharged from output tube 7 after motor section by press part.
In the prior art, the body of compressor is connected with the assembling of housing 4, earlier motor section and press part are assembled respectively, wherein, running shaft 1 is assembled in the press part, and then by running shaft 1 being inserted into the center of the rotor 2 of motor section, and motor section and press part are fitted together, and be installed in the housing 4 of compressor, the mode that adopts three spot welding is fixed together the body and the shell 4 of compressor.Specifically the upper bearing 6 of the press part mode by three spot welding is welded on the housing 4 of compressor, forms solder joint 15 as shown in Figure 1.
But, in the process of welding, high temperature during its welding passes to upper bearing 6, must produce high temperature thereon, cause it to produce thermal distortion, thereby cause the imprecision of compression volume 18 sealings, influence the working efficiency of compressor, and the place is easy to generate leakage at solder joint, and the welding slag of generation can influence the life-span of compressor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and can avoid compressor leakage, thermal distortion, the body of the compressor in raising compressor life-span and the fixed structure of housing.
The technical solution adopted in the present invention is: a kind of body of compressor and the fixed structure of housing, in compressor housing, comprise and being provided with: constitute motor section stator, be positioned at stator Zhou Bingyu its constitute concentrically ringed rotor, be pressed into the running shaft of centre of rotor portion, the lower end of running shaft is formed with eccentric part; Constitute on the cylinder of press part, the combine closely upper bearing that in the upper/lower terminal face of cylinder, connects running shaft and lower bearing, the upper bearing integrally formed be used for fixing running shaft on axle journal, the eccentric part of running shaft lower end is arranged in the compression volume of cylinder, is formed with the convex tendon of protrusion on the inner peripheral surface of housing; On the outer circumferential face of the stator of motor section be formed with correspondingly respectively on the outer circumferential face at upper bearing with the convex tendon on the housing, can embed the groove of convex tendon; The lower end that is positioned at upper bearing on the inner peripheral surface of housing also is formed with the boss that is used to support upper bearing.
The upper end that is positioned at stator on the inner peripheral surface of described housing also is formed with the boss that is used for fixing compressor block.
Convex tendon on the described housing be shaped as long prismatic shape.
Groove on the described stator periphery is connected the groove of the corresponding long prismatic shape of convex tendon on common formation and the housing with the groove on the upper bearing periphery.
Boss on the described housing and boss are provided with more than three along the circumference of housing separately.
The body of compressor of the present invention and the linkage structure of housing, owing to adopt the boss that support and fixed electrical machinery portion and press part are set on housing, and on housing, be provided with convex tendon, can embed simultaneously the groove of convex tendon outer circumferential face being provided with of the periphery of stator and upper bearing, make in the firm housing that is fixed on compressor of the body of compressor, also accurate in locating is in the housing of compressor.Avoided owing to welding the inhomogeneous thermal stress that produces of being heated.Also avoided simultaneously the leakage phenomenon that produces because of welding, and the pollution that causes of welding slag, the efficient and the working life of having improved compressor greatly.
