Crankshaft, compressor and vehicle

Abstract

The invention provides a crankshaft, a compressor and a vehicle. The crankshaft comprises a first shaft body and a second shaft body, wherein the first shaft body is provided with a first axis line, an eccentric hole deviating from the first axis is formed in the end surface of one end of the first shaft body, the second shaft body is provided with a second axis line, an eccentric column deviatingfrom the second axis line is formed in the end surface of one end of the second shaft body, the eccentric column is inserted into the eccentric hole, a one-way rotation limiting mechanism is arrangedbetween the eccentric column and the eccentric hole, and the one-way rotation limiting mechanism is used for ensuring that the eccentric column rotates in a first rotation direction relative to the eccentric hole and cannot rotate in a second rotation direction opposite to the first rotation direction. According to the crankshaft, the compressor and the vehicle, the eccentricity of the eccentricpart of the crankshaft can be adjusted, and high universality is achieved.

Description

technical field [0001] The invention belongs to the technical field of compressor manufacturing, and in particular relates to a crankshaft, a compressor and a vehicle. Background technique [0002] The crankshaft is the power transmission part of the compressor. The motor transmits power to the compressor through the crankshaft, and drives the compressor to compress the refrigerant or air. The traditional processing method of the crankshaft is to use a lathe to turn. Since the eccentric part needs to be turned, the processing efficiency is low and the operation is difficult. It is difficult to ensure the stability of the processed parts and it is prone to defects. The shaft and the eccentric part are separately processed and assembled into a split crankshaft, but the eccentricity of the existing split crankshaft cannot be adjusted, which leads to the replacement of a new crankshaft when the eccentricity of the crankshaft needs to be adjusted, which is time-consuming and labo...

Problems solved by technology

The traditional processing method of the crankshaft is to use a lathe to turn. Since the eccentric part needs to be turned, the processing efficiency is low and the operation is difficult. It is difficult to ensure the stability of the processed parts and it is prone to defects. The shaft and the eccentric part are separately processed and assembled into a split crankshaft, but the eccentricity of the existing split crankshaft cannot be adjusted, which leads to the replacement of a new crankshaft when the eccentricity of the crankshaft needs to be adjusted, which is time-consuming and laborious, and not economical Good, and it is very easy to damage the connected motor components such as the rotor during the replacement process, which will affect the performance of the motor and even the compressor
