Problems solved by technology

Also, after the assembly of the shaft seal is completed, the holder needs to be assembled, so the number of parts increases and the assembly process also increases, thereby reducing cost competitiveness
In addition, if there is a tolerance in the processing part for placing the holder, the holder may come off and the quality of the compressor may deteriorate.

Embodiment Construction

[0028] Hereinafter, an electric compressor according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0029] First, using an electric compressor as an example, the structure of the drive unit will be briefly described.

[0030] The electric compressor 100 of the present invention is driven by a motor and an inverter, and is roughly divided into a drive unit 103 , a compression unit 105 and a control unit 107 .

[0031] The driving unit 103 includes: a main housing 100a for forming an appearance; and a stator 135 and a rotor 141 coaxially attached inside the main housing 100a. Also, the compression unit 105 includes: a compression unit housing 150 combined with the rear of the main housing 100a to form an appearance; Install. Simultaneously, control part 107 comprises: cover housing 163, is combined with the front of main housing 100a, is used to form outward appearance; .

[0032] When the refrigerant is compressed by ...

Abstract

The present invention relates to an electric compressor capable of fixing a shaft seal without a fixing retainer of the shaft seal, the electric compressor comprising: a shaft (300) rotatably coupledinside a main housing (100a); and a shaft seal (500), which is press-fitted between the shaft (300) and the main housing (100a), seals a gap between the shaft (300) and the main housing (100a) by an elastic structure, prevents deformation of the elastic structure by means of a rigid structure formed integrally with the elastic structure, and maintains a coupling position through the frictional force of the elastic structure.

Description

technical field [0001] The present invention relates to an electric compressor, and more specifically, to an electric compressor capable of fixing a shaft seal without a fixing fixture for the shaft seal. Background technique [0002] Generally, a compressor suitable for an air-conditioning system has a function of sucking gas refrigerant passing through an evaporator to compress it into a high-temperature and high-pressure gas refrigerant state, and discharging it through a refrigerator. The above-mentioned compressor uses a reciprocating Mobile, rotary, scroll, swash plate and other types of compressors. [0003] Generally, among such compressors, a compressor using an electric motor as a power source is called an electric compressor. An electric compressor is disclosed in Korean Patent Publication No. 2014-0007706. [0004] The swash plate type compressor in the existing literature includes: a drive shaft, which is rotatably supported in combination with a shaft seal pr...
