ROTOR AND ROTARY MACHINE

Document Type and Number:

Japanese Patent JP2003065392

Kind Code:

A

Abstract:

To provide a rotor capable of suppressing rotation-oscillation of a rotor body and capable of reducing noise.

A power transmission mechanism PT fitted to a compressor comprises a bearing member 42 secured to a drive shaft 16 and pulley 17 which is action-connected to the bearing member 42 while supported by the housing of the compressor. The pulley 17 is provided with a recessed part 17D for housing roller 46. The roller 46 moves along a rolling-guide surface 17E of arc in cross section which is formed in the recessed part 17D, to provide an action of pendulum. The action of pendulum suppresses rotation-oscillation generated at the pulley 17. A lid 47 provided to an opening of the recessed part 17D and the pulley 17 are made from resin to reduce noises generated by collision between the roller and the inside surface of the recessed part 17D and the lid 47.
