Problems solved by technology

The main shaft drives the movable scroll through the eccentric sleeve. The eccentricity of the main shaft of the existing scroll compressor cannot be adjusted, which makes the scroll compressor less adaptable to different speeds and loads, and the main shaft pin hole and eccentricity on the main shaft There is a collision between the adjustment pins on the sleeve, which makes the scroll compressor have abnormal noise when it is started or stopped, and the noise is relatively large

Embodiment 1

[0031] Such as figure 1 As shown, the scroll compressor is a volumetric compression compressor, and the compression components are composed of a movable scroll 100 and a fixed scroll 200 . The main shaft 1 drives the movable scroll 100 to move through the eccentric sleeve 2. The eccentricity of the main shaft 1 of the existing scroll compressor cannot be adjusted, which makes the adaptability of the scroll compressor to different speeds and loads poor, and the There is a collision between the main shaft pin hole and the adjustment pin 21 on the eccentric sleeve 2, which makes the scroll compressor produce abnormal noise and relatively loud noise when it is started or stopped.

[0032] Such as Figure 2-Figure 3 As shown, this embodiment provides a radially flexible structure of a scroll compressor, including a main shaft 1 and an eccentric sleeve 2, the main shaft 1 is provided with a main shaft pin hole 11, the eccentric sleeve 2 is provided with an adjustment pin 21, and th...

Embodiment 2

[0038] Such as Figure 5 As shown, the radially flexible structure of the scroll compressor provided by this embodiment is roughly the same as that of Embodiment 1, the difference is that the outer peripheral wall of the transverse section of the adjustment sleeve 3 is in a C-shaped broken shape, and after the installation is completed , the C-shaped break-shaped slit is closed, and the outer peripheral wall of the transverse section is a complete circle after closing. Further, in this embodiment, the distances between the opposite peripheral walls of the longitudinal section of the adjustment sleeve 3 are equal.

[0039] It should be noted that in Embodiment 1 and Embodiment 2, the specific shape of the outer peripheral wall of the transverse section of the adjustment sleeve 3, whether the outer peripheral wall of the transverse section is closed, and the specific shape of the outer peripheral wall of the longitudinal section of the sleeve 3 can be combined arbitrarily. For ...

Abstract

The invention relates to the technical field of scroll compressors, in particular to a radial flexible structure of a scroll compressor and the scroll compressor. The radial flexible structure of the scroll compressor comprises a main shaft and an eccentric sleeve; the main shaft is provided with a main shaft pin hole and a positioning column; the eccentric sleeve is provided with an adjusting pin and a positioning hole; the adjusting pin can be matched with the main shaft pin hole; the positioning column is matched with the positioning hole; the radial flexible structure of the scroll compressor further comprises an adjusting sleeve; the adjusting sleeve is clamped between the pin hole of the main shaft and the adjusting pin; and the adjusting sleeve is an elastic adjusting sleeve, so that the adjusting pin can be finely adjusted left and right around the positioning column of the main shaft. According to the radial flexible structure of a scroll compressor and the scroll compressor, by arranging the adjusting sleeve between the main shaft pin hole and the adjusting pin, the adjusting pin on the eccentric sleeve can be finely adjusted left and right around the positioning column of the main shaft by utilizing the elasticity of the adjusting sleeve, so that the eccentricity of the main shaft is adjusted, and meanwhile, the collision between the outer wall of the adjusting pin and the inner wall of the main shaft pin hole is avoided, and abnormal sound generated when the scroll compressor is started and stopped is eliminated.

Description

technical field [0001] The invention relates to the technical field of scroll compressors, in particular to a radially flexible structure of a scroll compressor and the scroll compressor. Background technique [0002] The scroll compressor is a volumetric compression compressor, and the compression part is composed of a moving scroll and a fixed scroll. The main shaft drives the movable scroll through the eccentric sleeve. The eccentricity of the main shaft of the existing scroll compressor cannot be adjusted, which makes the scroll compressor less adaptable to different speeds and loads, and the main shaft pin hole and eccentricity on the main shaft There is impact between the adjustment pins on the sleeve, which makes the scroll compressor make abnormal noise when it is started or stopped, and the noise is relatively large. Contents of the invention [0003] The purpose of the present invention is to provide a radially flexible structure of a scroll compressor, so that ...
