Abstract

The invention belongs to a scroll compressor, and relates to a fixing structure of fixed scroll of scroll compressor. It is characterized by that in the fixing structure of fixed scroll an upper supporting frame is set in the upper side of interior of closed container formed from upper top cover and tank body, and the fixed scroll is fixed on said upper supporting frame. Said fixing grooves are formed on the upper supporting frame, and on the undersurface of said fixed scroll several fixing pins which can be inserted and fixed in the fixing grooves are formed. Said invention also provides its fixing method, said structure is simple, and can prevent the fixed scroll from moving.

Description

technical field [0001] The invention belongs to a scroll compressor, in particular to a fixed scroll fixed structure of a scroll compressor which does not use bolts to fix the fixed scroll to an upper support to prevent its axial and radial movement. Background technique [0002] Figures 1 and 2 show scroll compressors in the prior art used in compressors for air conditioners and refrigerators, which are briefly described as follows. [0003] As shown in the figure, an upper support (2) is fixed on the inner upper part of the airtight container (1) having a receiving space inside, and a lower support (3) is fixed on the lower part thereof. [0004] A stator (4) is arranged between the upper support (2) and the lower support (3), and a motor (6) constituted by a rotor (5) rotatably coupled to the inside of the stator (4). The upper and lower parts of the rotor (5) are equipped with balance weights (BW) for adjusting the unbalanced rotation of the rotor (5) when it rotates. ...
