Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0035] see image 3 and Figure 13 , four radially protruding first flanges are arranged at intervals on the outer periphery of the non-revolving scroll, and the first through holes 12, 14, 16 and 18 of the same aperture are respectively opened on the first flange along the axial direction, or gaps 12', 14', 16' and 18', a first threaded hole 20, 22, 24, 26, 28, 30, 32 and 34 is evenly distributed on both sides of each first through hole or notch.

[0036] see Figure 4 , the appearance of the first sleeve in the installation mechanism of the present invention is T-shaped, the first sleeve is provided with a second through hole 40 along the center of the axial direction, and the expansion part of the upper part forms the second flange 38, and the second flange 38 Both sides of the upper second through hole 40 are provided with third through...

Abstract

The invention discloses a non-revolving scroll installation mechanism of a scroll compressor and an installation method thereof. One of the parts of each installation mechanism is installed on the non-revolving scroll, and the other part is installed on the frame. Each installation mechanism is provided with a sliding mating surface, and the non-revolving scroll is installed by using this installation mechanism. On the frame, a small amount of axial movement of the non-orbiting scroll is allowed in the direction away from the orbiting scroll. The use of this installation mechanism can ensure that the processing accuracy and processing cost are reduced without reducing the assembly accuracy requirements, so that when the scroll compressor is working normally, the non-revolving scroll and the end plate surface of the revolving scroll are in close contact; When an abnormality occurs, the non-revolving scroll and the orbiting scroll can be separated in time to ensure the reliability of the compressor under severe working conditions.

Description

technical field [0001] The invention relates to a scroll compressor, in particular to a mounting mechanism and a mounting method for a non-revolving scroll of the scroll compressor. Background technique [0002] Existing scroll compressors include a non-revolving scroll with a scroll crimp on the bottom plate and an orbiting scroll with a scroll curl on the end plate, and the two scrolls face each other Meshing configurations compress fluid entering a scroll compressor by sequentially constricting a plurality of compression chambers formed between mutual curls. [0003] When the fluid sucked into the compression chamber contains liquid, because the liquid has little compressibility, a so-called liquid hammer is formed in the compression chamber, which damages the scroll of the compressor, causing the compressor to fail or even an accident. Therefore, it is necessary to set up a device to prevent such incidents. U.S. Patent 4,767,293 discloses a unique axially flexible insta...
