RECIPROCATING COMPRESSOR AND REFRIGERATING MACHINE HAVING THE SAME

摘要

Disclosed are a reciprocating compressor and a refrigerating apparatus (200) having the same, wherein a magnet bearing is inserted between facing surfaces between a cylinder block and a crank shaft and the magnet bearing (300) so as to generate a magnetic force both in a shaft direction and in a radial direction, so that the cylinder block (210) and the crank shaft (220) can be supported both in the shaft direction and in the radial direction, thereby reducing a frictional loss due to an eccentric load of the crank shaft (220), and also, both magnets (310, 320) are disposed to overlap each other so as to prevent an increase in an input load due to the magnetic between the magnets (310, 320), resulting in further improvement of energy efficiency of the compressor.
