Title:

POWER TRANSMISSION MECHANISM

Document Type and Number:

WIPO Patent Application WO/1999/028643

Kind Code:

A1

Abstract:

A power transmission mechanism for power-transmittably coupling a rotating unit of a compressor (11) composed of a drive shaft (17), a rotating support (23) and a swash plate (27) with an engine (62), comprising a pulley (56) and an armature (58), both of which constitute a first rotating body provided on a side of the engine, a hub (57), which serve as a second rotating body coupled to the drive shaft of the compressor, and a spring (64), which serves as an elastic means for coupling the first and second rotating bodies. A spring constant of the spring (64) is set such that a resonant frequency (fR) determined by the spring constant and a sum of a moment of inertia of the rotating unit of the compressor and a moment of inertia of the second rotating body as dominant factors is made smaller than a minimum frequency (f1) of torque variation produced on the compressor and more preferably smaller than a minimum frequency (f2) of torque variation produced on the engine.
