Abstract:
Disclosed are a crankshaft for a reciprocating compressor, the crankshaft comprising: a main shaft (1), a counter shaft (2) and a crank arm (3), the main shaft (1) and the counter shaft (2) being respectively arranged on two sides of the crank arm (3), the two sides of the crank arm (3) being respectively provided with a first counter bore (31) and a second counter bore (32), the main shaft (1) being installed in the first counter bore (31), and the counter shaft (2) being installed in the second counter bore (32), wherein a reciprocating compressor has the crankshaft. The main shaft (1), the counter shaft (2) and the crank arm (3) being separate parts enables the crankshaft to be formed simply and to be machined easily. Compared with traditional casting processes, the mass, the material cost and the machining cost of the crankshaft can be reduced; and the power of the reciprocating compressor during operation is reduced at least to a certain extent, improving the reliability of the reciprocating compressor.
