Title:
COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2017/065032
Kind Code:
A1
Abstract:
This compressor is provided with a rotating shaft (12) having an eccentric part (26), an electric motor having a rotor (6) linked to the rotating shaft (12), a compression mechanism section driven by the electric motor via the rotating shaft (12), a first balancing weight (101) provided to one end, in the axial direction, on the side of the rotor (6) that faces the compression mechanism section, and a second balancing weight (102) provided to the other end of the rotor (6) in the axial-direction. The first and second balancing weights (101, 102) are disposed so that the centers of gravity of the first and second balancing weights (101, 102) are positioned at pre-set advanced angles θ1, θ2 in the rotational direction of the rotor (6), relative to a reference plane passing through the rotational center O of the rotating shaft (12), along the eccentric direction of the eccentric part (26). A compressor is thereby provided in which vibration and noise of the rotor can be reduced inexpensively and with a simple configuration, without adding any new components.
