Problems solved by technology

[0007] Also, when a plurality of bearings are installed close together to prevent the crankshaft from bending, the behavior of the crankshaft can be stabilized, but since the bearing area increases due to the increase in the number of bearings, frictional loss increases, and the service life of the bearings increases due to the increase in the number of bearings. Bearing location shortened
[0008] Increased friction loss and shortened bearing life will result in lower compressor efficiency and shorter bearing replacement intervals

Abstract

A hermetic compressor includes: a crank shaft rotated by using an axial direction as a rotational axis; a stator rotating the crank shaft; a first bearing penetrated by the crank shaft and rotatably coupled to one side of the crank shaft based on the stator to support one side of the crank shaft when the crank shaft is rotated; a support part having one side provided at the stator and the other side disposed to be adjacent to the other side of the crank shaft, based on the stator; and a second bearing coupled to the other side of the support part and supporting the other side of the crank shaft.

Description

technical field [0001] The present invention relates to a hermetic compressor, and more particularly, to a hermetic compressor capable of reducing frictional loss of a crankshaft and prolonging the service life of a bearing supporting the crankshaft. Background technique [0002] A common hermetic compressor includes a motor part disposed in a hermetic container and generating power, and a compression part that operates when receiving power from the motor part. Hermetic compressors may be classified into reciprocating compressors, rotary compressors, vane compressors, scroll compressors, etc. according to how refrigerant (compressible fluid) is compressed. [0003] In the hermetic compressor, a crankshaft coupled to a rotor of the motor part transmits power while rotating together with the rotor, and an interconnection member coupled to the crankshaft and receiving power from the motor part forms a compression chamber to compress refrigerant. [0004] In the hermetic compre...
