Abstract
The present invention is internal structure welding and supporting mode for rotary compressor. The internal structure includes stator and rotor with rotation shaft embedded in the center, and the rotation shaft is provided with cylinder, upper and lower bearings to support both rotation shaft and the cylinder. Outside the casing, there are liquid storage and exhaust pipe on the top cover. The said structure is supported via upper bearing and welding to the casing inside the casing, and near the welded points there are slots for absorbing and remitting heat deformation of the main shaft during welding. The present invention can ensure the fit precision, and the slots results in saving in material and raised performance/cost ratio.
Description
Technical field
The present invention relates to the invention of a kind of rotary compressor welding supporting way aspect.Further say so at the rotary compressor upper bearing, reduce the rotary compressor internal structure welding supporting way that when welding, causes main bearing temperature distortion amount by slotted eye is set.
Background technique
Under the ordinary circumstance, rotary compressor be with running shaft that motor combines on off-centre be combined with press part and roll ring, roll ring and in circular cylinder, carry out linear motion, suck refrigerant and compress and discharge.
Tradition rotary compressor structure as shown in Figure 1, it is to be made of following structure: be provided with suction port 109a and output tube 118, and the inside that is filled with the shell A of certain gauging is equipped with the stator 103 and the rotor 102 of motor; And be pressed into running shaft 105 at the center of its rotor 103; Below running shaft 105, be provided with the press part that absorbs compression refrigerant.
Press part is made of following structure: the circular cylinder 109 that is fixed on the inner peripheral surface of shell A and connects with suction pipe; The upper bearing 110 and the lower bearing 111 of combining closely and in the bi-side of cylinder 109, being through with running shaft 105; With running shaft 105 is the center, and that carries out in cylinder 109 simultaneously that off-centre rotatablely moves rolls ring 107, and is provided with the compression volume 108 that forms compression refrigerant gas when rolling ring 107 rotations with upper bearing 110, lower bearing 111.
Be provided with the liquid-storage container 117 that prevents that liquid refrigerant from entering in the suction port 109a of cylinder 109 connection, and on seal container A, be provided with the output tube 118 of the high pressure refrigerator gas of output compressor section 112 compressions.
After the existing closed rotary compressor that as above constitutes connected power supply, the rotor 102 of motor part 104 drove the rotating shaft 105 that is pressed in rotor 102 and together rotates.Rotation along with rotating shaft 105, the eccentric part 106 that rotating shaft 105 lower ends form and roll ring 107 rotations with eccentric part 106 combines will enter the refrigerant gas that compression volume 108 interior low-temperature low-pressure refrigerant gas compressions become High Temperature High Pressure through the suction port 109a of cylinder 109.
Exported by valve member through as above process compressed refrigerant, the inside by the through hole 116a of baffler 116 exports seal container A to is outputing to the outside through the slit between rotor 102 and the stator 103 by output tube 118 afterwards.
As shown in Figure 2, original rotary compressor adopts the supporting way that cylinder 109 and shell A weld mostly.The combination of this welding, because the internal diameter of cylinder body 109 is relatively large, the thickness of edge section is less relatively, causes malformation easily when welding, simultaneously less relatively because of the thickness of edge section, the soundness of welding is also relatively poor relatively.Now just progressively adopt the supporting way of main bearing and shell welding.Promptly as shown in Figure 2, adopt the supporting way of upper bearing and shell welding.But this welded structure because the bearing heat absorption area is bigger, also very easily causes the main bearing temperature distortion.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of under the prerequisite of proof strength, can absorb and alleviate the rotary compressor internal structure welding supporting way of the main bearing temperature distortion amount that causes when welding to greatest extent.
The technical solution adopted in the present invention is: a kind of rotary compressor internal structure welding supporting way, and its compressor is the container that is made of upper and lower cover and housing, the internal structure of container includes stator and the rotor of forming motor; And be pressed into rotating shaft in its centre of rotor; The outside of the eccentric part that forms in the lower end of rotating shaft is provided with rolling in eccentric part and encircles when rotating, constitute the cylinder of the compression volume of compression refrigeration gas, also support when supporting the rotating shaft lower end cylinder on, lower bearing, be provided with the liquid-storage container that the suction port that forms with the compression volume side of cylinder links to each other in the outside of housing, be arranged on loam cake above, compressed refrigerant is outputed to the outlet pipe of outside of containers, on upper bearing, be with baffler, above-mentioned internal structure is that the mode that adopts upper bearing and housing welding to support is fixing within the outer shell, and at the circle of upper bearing, near solder joint and do not have the place of solder joint to have several can to absorb and alleviate the slotted eye that when welding, causes main bearing temperature distortion amount near cylindrical.
The present invention has several annular slotted holes at circumference when satisfying join strength, and the bond pad locations that main bearing is connected with external casing is chosen in approaches the circular groove place.Therefore, under the prerequisite of proof strength, slotted eye can absorb and alleviate the amount of the main bearing temperature distortion that causes to greatest extent when welding, guaranteed the requirement that cooperates with other parts.Because of being provided with several slotted eyes, effectively save raw material simultaneously, had high cost performance.
