Compressor, air conditioner and vehicle

Abstract

The invention is suitable for the technical field of refrigeration and heating, and provides a compressor, an air conditioner and a vehicle, the compressor comprises a crankshaft, a crank pin, an eccentric sleeve and a scroll plate assembly, one end of the crankshaft is provided with an eccentric hole, one end of the crank pin is inserted into the eccentric hole and is in clearance fit with the eccentric hole, and the other end of the crank pin is exposed out of the eccentric hole; the eccentric sleeve is fixedly connected or in clearance fit with the other end of the crank pin, and the vortex plate assembly is connected to the eccentric sleeve; due to the clearance fit of the crank pin and the crankshaft, the situation that the thin position, corresponding to the outer side of the eccentric hole, on the crankshaft deforms due to the fact that the crank pin is assembled on the crankshaft in an interference mode can be avoided, and therefore the problem that an inner check ring raceway of a main bearing matched with the crankshaft deforms is avoided, the shaft system rotating precision is further prevented from being reduced, and finally the shaft system rotating precision is improved. The operation vibration of the compressor is reduced, and further, the operation noise of the compressor is reduced, so that the operation vibration and noise of the compressor are low.

Description

Technical field [0001] The present application relates to the field of cooling heat, and in particular, there is a compressor, air conditioner, and vehicle. Background technique [0002] At present, with the development of new energy vehicles, consumers have further improved the noise, vibration and durability requirements of air conditioning compressors. [0003] figure 1 and figure 2 The display is a partial structure cross section of a scroll compressor 100 'applied to a vehicle. Generally, the structural design of the scroll compressor 100 'is compact, in order to improve the intensity of the crankshaft assembly, the crankshaft assembly is designed with a split structure, that is, the crankshaft 2', the crankshaft 2 ', the crank pin 3' (i.e., eccentric pin) Inserting the eccentric hole 1 ', the crankshaft 2' is connected in a manner with the crank pin 3 '. Since the crankshaft 2 'and the crank pin 3' are eccentric configuration, the wall thickness between the outer circumfer...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the embodiment of the present application is to provide a compressor, aiming at solving the problem of the interference fit between the crankshaft and the crank pin in the prior art, which causes the poor roundness of the outer peripheral surface of the crankshaft and the deformation of the inner retaining ring of the main bearing, which causes abnormal vibration of the compressor shaft system. , and then cause technical problems of abnormal compressor noise
