Embodiment 1

[0032] combine Figure 4 and Figure 5 The eccentric sleeve of this embodiment will be described in detail.

[0033] The eccentric sleeve of the present embodiment includes a mounting part 101, and a through hole 102 is formed on the mounting part 101, such as Figure 4 or Figure 5 shown. The crankshaft 2 is assembled in the through hole 102 and forms a gap with the through hole 102 , and at least one oil return structure is provided on the installation part 101 , and the at least one oil return structure communicates with the gap.

[0034] In this embodiment, at least one oil return structure is provided on the installation part 101 of the eccentric sleeve, and the at least one oil return structure communicates with the gap formed between the crankshaft 2 and the through hole 102, so that the oil return structure appears in the through hole of the installation part during the operation of the compressor. 102 and the yellow grease and impurities on the end face 103 can be...

Embodiment 2

[0051] to combine Image 6 The oil return device and the scroll compressor of this embodiment will be described in detail.

[0052] The oil return device of this embodiment includes at least one oil return structure on the eccentric sleeve of any technical solution of this embodiment. At least one oil return structure on the eccentric sleeve in this embodiment can make the oil return and lubrication at the joints of the eccentric sleeve 1, the crankshaft 2 and the bracket assembly 7 smoother, thereby improving the oil return and lubrication effects of the compressor through the oil circuit circulation , reduce the amount of yellow grease attached, improve the service life of the compressor.

[0053] According to a preferred embodiment, the lubrication circuit of the preferred technical solution of this embodiment needs to pass through the following components: such as Image 6 As shown, during the operation of the compressor, the low-pressure gas enters the suction cavity th...

Abstract

The invention discloses an eccentric sleeve, an oil return device and a scroll compressor, and relates to the technical field of compressors. The technical problems that in the prior art, since yellowoil dirt and impurities appear at eccentric sleeve through holes and end faces, the heat dissipation and lubrication effects of a compressor are influenced are solved. The eccentric sleeve comprisesan installing part provided with a through hole, a crankshaft is assembled in the through hole, a gap is formed between the crankshaft and the through hole, the installing part is further provided with at least one oil return structure, and at least one oil return structure communicates with the gap. According to the eccentric sleeve, the yellow oil dirt and the impurities attached to the eccentric sleeve installing part can be discharged through gaps between at least one oil return structure and / or the crankshaft and the through hole, accordingly, the oil return and lubrication effects of thecompressor can be improved, and the service life of the compressor is prolonged.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an eccentric sleeve, an oil return device and a scroll compressor. Background technique [0002] Due to its small size and high efficiency, the scroll compressor has become the preferred compressor type in passenger cars, and the eccentric sleeve is a flexible sealing structure commonly used in the existing automotive scroll compressors. figure 1 It shows a structural schematic view of the assembled eccentric sleeve and the crankshaft in the prior art; figure 2 A top view of an eccentric sleeve in the prior art is shown; image 3 A cross-sectional view of a preferred embodiment of a prior art turbo compressor is shown. Such as Figure 1 ~ Figure 3 As shown, in the prior art, the eccentric sleeve and the crankshaft are in a gap fit, and there is no lubricating channel on the eccentric sleeve, and the effects of lubrication and heat dissipation can only be achieved through ...
