Abstract: A reciprocating compressor includes a shell, a driving motor, a drive shaft, a piston, a cylinder block, and a support plate disposed between the driving motor and the cylinder block to support the cylinder block with respect to the drive motor in an axial direction of the drive shaft. The support plate has one side surface coupled to the stator and another side surface coupled to the cylinder block. The reciprocating compressor is light-weighted and/or miniaturized by reducing a weight of the cylinder block, and perpendicularity and roundness with respect to the cylinder portion and the bearing portion is secured to improve reliability.

Abstract: A rotary compressor, a method of manufacturing a rotary compressor, and an apparatus for manufacturing a rotary compressor are provided. The rotary compressor may include a case having an inner space, a stator to which power may be applied, the stator being disposed in the case, and a compression mechanism disposed on or at one side of the stator to generate a compression force of a refrigerant. The compression mechanism may include a rotational shaft, a cylinder that accommodates a roller coupled to the rotational shaft, a main bearing coupled a first side of the cylinder, and a sub bearing coupled to a second side of the cylinder. The main bearing may be press-fitted and fixed to an inner surface of the case.
