Abstract

The invention provides a compressor. A motor and an air cylinder are contained in a shell. A bent axle is provided with a long axle part, an eccentric part and a short axle part. The bent axle transmits rotation force of the motor to the air cylinder to compress refrigerant. Compression space is jointly defined by a first bearing assembly, a second bearing assembly and the air cylinder, and the bent axle is supported. The first bearing assembly comprises a main bearing located between the motor and the air cylinder, and a thrust bush. The main bearing is provided with a disc part with a through hole and an inner edge part protruding upwards from the inner circumference of the disc part. The material of the thrust bush is more resistant to abrasion than the material of the main bearing. The thrust bush is provided with a bent axle supporting part and a thrust part bearing the bent axle. The bent axle supporting part is located in the through hole of the main bearing and provided with an inner hole supporting the bent axle so as to be arranged on the long axle part of the bent axle in a sleeving manner. The thrust bush is additionally arranged at the main bearing of the compressor, and the problem of friction abrasion of two friction faces can be solved at a time through one-time pressing.

Description

technical field

[0001] The invention relates to a compressor, in particular to a fully enclosed rolling rotor compressor. Background technique

[0002] In general, a hermetic compressor includes a motor for generating a driving force in an inner space of a hermetically sealed case, and a compression part coupled to the motor for compressing refrigerant. Hermetic compressors can be classified into reciprocating compressors, scroll compressors, and rolling rotor compressors according to different refrigerant compression mechanisms. Reciprocating compressors, scroll compressors, and rolling rotor compressors all utilize the rotational force of an electric motor.

[0003] The motor of the existing hermetic compressor utilizing rotational force has a crankshaft, and the rotational force of the motor is transmitted to the compression part through the crankshaft. figure 1 Shown is a structural schematic diagram of a rolling rotor compressor in the prior art. As shown in the figu...
