<p>PROBLEM TO BE SOLVED: To provide a coupling which can maintain good actuation and buffering, and more reduce efficiently the vibration or the noise of a compressor by the tortional and the axial vibrations of a rotating shaft. SOLUTION: The coupling comprise a hub 1 installed on a rotating shaft f, an outer ring 2 installed to an armature g which is attached into a rotor b by an actuation of electromagnetic coil a, a main elastomer 3 connecting elastically the hub 1 to the outer ring 2, a sleeve 4 pressed to fit into the rim 13 of the hub 1, a mass part 5 concentrically arranged to the sleeve 4, and a sub elastomer 6 adhered into the distance between the sleeve 4 and the mass part 5. Furthermore, the sub elastomer 6 and the mass part 5 form an adsorption part D, and the natural frequency of the adsorption part D is set into a predetermined frequency range to reduce.</p> |
