Description
Technical field
The present invention relates to scroll compressor and assembling method thereof, particularly relate to, make main frame and auxilliary framework coaxial, thereby can improve the scroll compressor and the assembling method thereof of compression efficiency and reliability by when auxilliary framework is set, supporting auxilliary framework.
Background technique
Generally speaking, compressor is the machine that is used for mechanical energy is converted to the compression energy of compressibility liquid.Usually, compressor can be divided into following several: reciprocating type, eddy type, centrifugal and blade type.The characteristics of scroll compressor are as follows: be different from and utilize the straight-line reciprocating type of piston, as centrifugal or blade type, utilize solid of rotation to suck gas and compress the compressor that discharge the back.
Fig. 1 is the profile diagram of the scroll compressor of prior art.Fig. 2 is the precedence diagram of packing engineering of the scroll compressor of prior art.As shown in Figure 1, the scroll compressor of prior art comprises following components and constitutes: the inner housing 10 that forms airtight containing space; Be arranged at the inner region of housing 10, after the refrigerant that sucks from the outside is compressed, be discharged to the press part 20 of the outside of housing 10; Be arranged at the downside of press part 20, the drive motor portion 30 of driving force is provided to press part 20.
Drive motor portion 30 comprises following components and constitutes: the stator 31 that is fixedly set in the inside of housing 10; The rotatable rotor 33 that is arranged at the inside of stator 31; Combine with rotor 33 one, be used to transmit the crankshaft 35 of the rotating force of drive motor.
In addition, the inner region of housing 10 is provided with main frame 37, and main frame 37 can support fixation whirlpool dish 21 and crankshaft 35.The middle section of main frame 37 is formed with the through hole 38 that can accommodate crankshaft 35.The main frame bearing 39 that is combined with drum is inserted in the inside of through hole 38, and main frame bearing 39 can be accommodated crankshaft, and rotatable support crankshaft 35.
The lower end area of crankshaft 35 is provided with auxilliary framework 41, and auxilliary framework 41 can be accommodated the lower end of crankshaft 35, and rotatable support.The middle section of auxilliary framework 41 is formed with auxilliary frame bearing 42, and auxilliary frame bearing 42 is contacted with the side edge and the lower end of crankshaft 35 respectively, can support the rotation of crankshaft.At this moment, main frame bearing 39 and auxilliary frame bearing 42 should maintain coaxial precision in a few μ m to tens mu m ranges, and crankshaft is rotated smoothly, thereby improve the performance of compressor.
As shown in Figure 2, the assembling method of the scroll compressor of aforesaid prior art is divided into following step and carries out: with 1st step 51 of main frame 37 secure bond in housing 10; One side of crankshaft 35 is inserted in the 2nd step 52 of main frame 37; Auxilliary framework 41 is incorporated into the 3rd step 53 of the opposite side of crankshaft 35; With auxilliary framework 41 secure bond in the 4th step 54 of housing 10.
Here, in the 4th step 54, be to utilize 3 spot welding modes will assist the mode that framework 41 is incorporated into housing 10 to carry out.At this moment, the welding deformation that cooling is shunk will take place in the molten metal of the high temperature around the weld part.In addition, because the temperature variation of parent metal and weld part is unbalanced, can suppress the contraction of expanding freely, therefore inner meeting produces residual stress.Because influences such as welding deformation and residual stress, auxilliary framework 41 can depart to specific direction not all the time, consequently, can cause being incorporated into the main frame bearing 39 of main frame 37 and be formed at the inconsistent phenomenon of central shaft between the auxilliary frame bearing 42 of auxilliary framework 41.As mentioned above, main frame 37 and auxilliary framework 41 can not be coaxial situation under, crankshaft can not rotate smoothly, and the rotating force that produces from drive motor portion 30 well can not be delivered to press part 20, therefore, can cause the compression efficiency of compressor and reliability to descend.
