STRUCTURE OF DRIVING PART IN ELECTROMOTIVE SCROLL COMPRESSOR

摘要

PURPOSE: A structure of an electric-powered scroll compressor driving portion is provided to reduce the noise and vibration by coupling a driving shaft and a rotor while maintaining a fixed compression load balance. CONSTITUTION: A structure of an electric-powered scroll compressor driving portion comprises a housing, a stator(510), a rotor(520) and a driving shaft(530). The stator is located inside the housing. The rotor is located inside the stator. The driving shaft is axis-connected in the center of the rotor and is revolved with the rotor as one body. A key slot is formed in the inner circumference of the rotor along the longitudinal direction. The driving shaft comprises a key(600) corresponding to the key slot. The driving shaft is combined in the rotor along the key slot of the rotor. The balance hole is formed in the rotor. The balance hole is formed into the longitudinal direction of the rotor.
