Bearing cooling structure of hermetic compressor

摘要

The present invention relates to a bearing cooling structure of a hermetic compressor that enables the bearing to be cooled effectively by oil drawn up as the crankshaft rotates.;In a hermetic compressor including a crank shaft having an oil bank and an oil supply groove formed on an outer circumferential surface thereof to allow oil to be sucked up, and a bearing fitted to an outer circumferential surface of the crank shaft.;At least one oil hole is formed in the boss portion of the bearing such that an upper surface of the bearing and an inner circumferential surface of the bearing corresponding to the oil bank communicate with each other so that a portion of the oil stored in the oil bank is transferred to the bearing through the oil hole. Characterized in that the discharge to the outer wall surface.
