Problems solved by technology

Since the fixing direction of the bolts for installing the fixed scroll (6) is also parallel to the axial direction, therefore, affected by the air pressure in the compression chamber, the bolts will loosen during the operation of the compressor, which in turn will cause the leakage of compressed gas and The noise and vibration of the compressor itself

Abstract

The invention discloses a fixed scroll disk fixing structure of scroll compressor. Said scroll compressor includes upper support frame mounted in the interior of external shell, fixing scroll disk fixed on the upper support frame and movable scroll disk which can be meshed with fixed scroll disk and can be used for forming several comperssion chambers. In the scroll disk mounting structure of scroll compressor at least one fixed scroll disk whose screw holt is inclined to oxial direction. Said scroll disk mounting structure can prevent leakage of compressed air and vibration due to noise so as to raise the performance and reliability of compressor.

Description

technical field [0001] The present invention relates to the structure of a scroll compressor, more specifically to a fixed scroll fixing structure of a scroll compressor that can improve the fixing strength in the axial, radial and tangential directions when fixing the upper bracket and the fixed scroll. Background technique [0002] Generally speaking, the scroll compressor is one of the compressors with high efficiency, low noise and widely used in various fields. It can form multiple compression chambers through the relative rotational movement of the fixed scroll and the movable scroll. When the compression chamber gradually moves to the central position, the volume of the compression chamber also gradually decreases, so that the continuous process of suction→compress gas→exhaust can be repeated. [0003] figure 1 It is the longitudinal section front view structural diagram of the existing scroll compressor, figure 2 It is a schematic diagram of the pressure force in...
