Embodiment 1

[0020] figure 1 and figure 2 Embodiment 1 is given, which is an embodiment in which the outer spiral teeth of the movable scroll member are thickened. This embodiment is designed for a compressor that is symmetrical to the compression chamber. The thickened area of ​​the scroll tooth is within the range of 180° at the outermost spread angle of the scroll tooth. In this area, the bottom profile line of the outer scroll tooth is a vortex line whose pitch increases with the increase of the spread angle. The thickness of the tooth starts from the outermost spread angle of the scroll tooth at 180 degrees, and increases with the increase of the scroll tooth spread angle, until the end of the scroll tooth, the thickness of the tooth top of the scroll tooth reaches 4mm, and the thickened surface is a The slope is inclined outward along the tooth top of the scroll tooth to the bottom of the tooth, the inclination angle is 15 degrees, and the cross-sectional shape of the scroll tooth...

Embodiment 2

[0025] image 3 and Figure 4 Embodiment 2 is given, which is an embodiment in which the outer side of the scroll is thickened, and is designed for a compressor with an asymmetrical compression cavity. The thickened area is within the range of 90° outside the compression chamber. The tooth thickness of the scroll tooth in the thickened area is a fixed value. It starts to thicken from the 90° outside of the scroll compression chamber to the end of the scroll tooth. , the increased thickness of the spiral is 4mm, and the thickened spiral has a rectangular section. The advantage of this embodiment is that the processing is more convenient than the first embodiment.

Abstract

The invention discloses reinforced volute teeth of a scroll compressor, which comprise a movable volute part and a fixed volute part, and are characterized in that: the tooth walls of volute teeth, unmeshed with the fixed volute part, at the outmost section of spiral volute teeth arranged on the movable volute part have an extra thickness which is 0.5 to 8mm; and the strength of the volute teeth at the section is more than or equal to that of volute teeth in an adjacent inner circle. The reinforced volute teeth of the scroll compressor have the advantages of increasing the strength of the volute teeth at the outmost section, solving the problem of damages to the volute teeth due to bending moment stress, improving the service life of the volute parts, and reducing maintenance and maintenance cost. The reinforced volute teeth of the scroll compressor also have the advantages of simple structure, convenient manufacture, less changes in the structural shape of original volute teeth and low manufacturing cost.

Description

technical field [0001] The present invention relates to a scroll compressor, in particular to a helical wrap on a movable scroll member of the scroll compressor. Background technique [0002] Traditional scroll compressors all have a fixed scroll part, a movable scroll part, and a cross ring moving part that can prevent the movable scroll part from rotating. Between the fixed scroll part and the movable scroll part, there are mutually matched spiral scroll teeth, and the mutually matched spiral scroll teeth form a chamber, and the mutual cooperative movement of the spiral scroll teeth forms the suction, compression and discharge chambers In this continuous movement, the refrigerant forms a continuous movement of suction, compression and discharge. For the curvature of the scroll tooth on the scroll part of the scroll compressor, the characteristic of its change is that the curvature becomes smaller and smaller as the spread angle of the scroll line increases. The strength ...
