High-temperature-resistance crankshaft for compressor

The invention discloses a high-temperature-resistance crankshaft for a compressor. The crankshaft comprises a clump weight, a link shaft neck is fixed to one end face of the clump weight, and an input end is fixed to one end of the link shaft neck; the outer surface of the clump weight is provided with an air inlet and an air guide cover, the air guide cover and the clump weight are of an integrated structure, the air inlet runs through the outer surface of the clump weight, extends to the inner side of the clump weight and is located below the air guide cover, and an air blowing hole is formed in the inner side of the clump weight. Through arrangement of the air guide cover, the air inlet, the air blowing hole and heat dissipation protrusions, the situation is avoided that friction heat generated when a link drives a main shaft to move is transmitted to the clump weight, the whole crankshaft is easily heated, and the fatigue of the crankshaft is influenced. Through arrangement of a first scrap discharging groove, a second scrap discharging groove and contact protrusions, small particles generated through friction between a bearing bush and the main shaft are conveniently discharged, and the situation is avoided that since the particles are increased, the main shaft is more severely worn, and accordingly the service life of the main shaft is influenced.
