Abstract
The present invention relates to a rolling rotor type compressor flange component connecting structure of rolling rotor type compressor, which includes a cylinder, an upper and lower cylinder cover, a bent shaft, a piston and blade, wherein the cylinder is set between the upper and lower cylinder cover, and constitutes a pump body with a housing; a flange that fixed with the pump body through bolt. The relative position of the flange and pump body is adjustable so as to keep the bent shaft center in accordance with the housing center. Compared with prior art, the present invention is provided with degree of consistency that can improve air gap in the compressor assembling process, can improve assembly quality, and miniaturize the compressor.
Description
Technical field
The present invention relates to compressor, be specifically related to a kind of flange component connection structure of rolling rotor type compressor.
Background technique
The mode that the welding of compressor pump and housing now adopts cylinder welding and upper cylinder cover to weld more.Cylinder welding manner mode because the influence in the assembly process can not be consistent the center of bent axle and housing center, causes the electric machine rotor air gap inhomogeneous, makes the product workmanship produce fluctuation.Because the welding heat influence makes cylinder produce distortion, influence compressor performance simultaneously.The upper cylinder cover welding manner though solved the problems referred to above, because upper cylinder cover is bigger, makes on the motor position and moves, and easily produces problems such as electromagnetism sound, is unfavorable for the miniaturization development of compressor simultaneously.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of uniformity that improves air gap in the compressor assembly process for the defective that overcomes above-mentioned prior art existence, improve assembly quality, make the flange component connection structure of the rolling rotor type compressor of compressor miniaturization simultaneously.
Purpose of the present invention can be achieved through the following technical solutions: a kind of flange component connection structure of rolling rotor type compressor, comprise cylinder, cylinder cap, bent axle, piston, blade up and down, cylinder is arranged on up and down between the cylinder cap, form the pump housing with housing, it is characterized in that also comprise flange, flange is fixed by the bolt and the pump housing, the relative position of the flange and the pump housing can be adjusted, so that crankshaft center and housing center are consistent.
Described flange is concentric with bent axle.
Described flange is welded on the housing.
Compared with prior art, the present invention has adopted a kind of structure of flange plate, can adjust cooperating of flange and the pump housing in the compressor assembly process, and crankshaft center is overlapped with the housing center.Reduce the influence of welding simultaneously, improve the efficient of compressor pump housing precision.After adopting flange arrangement, in the compressor assembly process, can adjust the relative position of the pump housing and flange, crankshaft center and housing center are consistent, improve the uniformity of compressor rotor air gap, improve the compressor assembly quality.And, owing to adopted flange arrangement, and being welded on the flange of the pump housing and housing, so reduced the influence of welding deformation, improved the performance of compressor for the pump housing.Owing to there is not higher upper cylinder cover, can effectively reduce the height of compressor simultaneously, make the compressor miniaturization.
Description of drawings
Fig. 1 is the schematic representation of the flange assembling of rolling rotor type compressor of the present invention;
Fig. 2 is the flange schematic representation of rolling rotor type compressor of the present invention;
Fig. 3 is the A-A sectional view of Fig. 2;
Fig. 4 is the B-B sectional view of Fig. 2.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Shown in Fig. 1～4, a kind of flange component connection structure of rolling rotor type compressor, flange 1 is fixed by bolt 2 and cylinder 3, can adjust the relative position of the flange 1 and the pump housing in the compressor assembly process, guarantees that bent axle 6 centers and housing 7 centers are consistent.
During assembling, earlier by the common fit assembling pump housing (cylinder 3, cylinder cap 4,5, bent axle 6, piston, blade) up and down, mounting flange 1 then, guarantees that flange 1 is concentric with bent axle 6, carries out the rotor hot jacket again.When the compressor general assembly, flange 1 is welded on the housing 7, carry out air gap inspection.If air gap is bad, can simply dismantle fixing bolt 2, carry out the pump housing again and install, to guarantee the position at bent axle 6 centers and housing 7 centers, guarantee the uniformity of rotor air gap.
