Original Abstract Submitted
a reciprocating compressor according to an embodiment of the present disclosure includes a crankshaft including a shaft portion, an eccentric mass portion, and a pin portion, and an oil groove positioned on an outer surface of the pin portion is configured to supply an oil to a pressurized portion of a bearing immediately before entering a section in which a gas load increases. for example, the oil groove can supply the oil to the bearing in a stroke section immediately before a crank angle reaches 270�. according to the above configuration, the oil is supplied to the pressurized portion of the bearing formed by the pin portion of the crankshaft and a connecting rod immediately before entering a stroke section subjected to a high load. accordingly, lubrication by the oil can be smoothly performed in the stroke section subjected to the high load, and oil shortage can be improved even if the oil groove adopts a structure in which the bearing is open at the top and bottom.
