STRUCTURE OF A BALL BEARING TYPE SMALL RECIPROCATING COMPRESSOR

WIPO Patent Application WO/2019/027131

A1

The structure of a ball bearing type small reciprocating compressor according to the present invention comprises: a block; a tubular cylinder coupled to the block; a valve assembly comprising a suction valve and a discharge valve to block a front end of the cylinder; a valve cover covering the valve assembly to form a suction space and a discharge space on an upper part of the valve assembly; at least one pressing bolt coupling the valve cover and the block so as to press the cylinder between the valve cover and the block; a piston conducting linear reciprocating motion in the cylinder; a stator coupled to the block; a rotor located to rotate relative to the stator; a rotation shaft coupled to the rotor to rotate integrally with the rotor so as to be rotatable and axially supported to the block; a crank part converting a rotation motion of the rotation shaft to a linear reciprocating motion of the piston; a connecting rod formed with an insertion cylindrical part and a rod part into which a journal and a bearing of the crank part are inserted; and an upper ball bearing and a lower ball bearing installed on an upper part and a lower part of the rotation shaft, respectively, wherein the lower ball bearing is installed inside an insertion cylindrical part protrudingly formed in the middle of the lower housing.
