Embodiment Construction

[0025] The present invention will be specifically described below in conjunction with the accompanying drawings and specific embodiments.

[0026] The scroll compressor in this embodiment, such as Figure 4 with 5 As shown, it includes a moving disk 240 with spiral teeth, a static disk 210, and a static disk cavity 230 for fixing the static disk 210. The bottom of the static disk cavity 230 is provided with at least two threaded holes 231, see Figure 5 , preferably, the at least two threaded holes 231 are equidistantly arranged at the bottom of the cavity 230 of the static disk 230 . The threaded hole 231 is provided with an adjusting screw 232, the top of which adjusts the screw 232 against the bottom of the static disk 210, and the bottom of the adjusting screw 232 is provided with a groove 233, see Image 6 .

[0027] The setting method of the groove 233 includes the following situations: it is arranged on the bottom end surface of the adjusting screw rod 232; on the i...

Abstract

The invention discloses a scroll compressor which comprises a moving disc and a static disc with scroll profile teeth, as well as a static disc cavity body for fixing the static disc, wherein, at least two threaded holes are formed at the bottom of the static disc cavity body, regulating threaded rods are arranged in the threaded holes, the top parts of the regulating threaded rods are pushed at the bottom of the static disc, and grooves are formed at the bottoms of the regulating threaded rods; and side walls of the scroll profile teeth of the moving disc and the static disc are arranged to be that the root parts are wider than the taper of the top parts. Compared with the prior art, the scroll compressor realizes the continuous adjustment of axial gap, reduces the time and the workload needed for regulating the axial gap and reduces the end surface abrasion between the moving disc and the static disc.

Description

technical field [0001] The invention relates to a compressor, in particular to a scroll compressor. Background technique [0002] The current scroll compressor structure is as follows: figure 1 As shown, the main components are two involute scrolls with the same shape but relative staggered angular positions by 180°. One is a fixed scroll (referred to as the stationary scroll 110), and the other is driven by an eccentric shaft. A moving scroll whose axis revolves around the axis of the static disk 110 (abbreviated as the moving disk 120). The static disk 110 and the static disk cavity 130 are fixedly connected by fixing bolts 135. The disk cavity 140 is fixedly connected to the static disk cavity 130 . [0003] Such as figure 2 As shown, after the installation of the moving disk 120 and the static disk 110 is completed, there is a certain axial gap 150 between them. The size of the axial gap 150 is critical. If the gap is too large, the leakage will be too large and the...
