  • Publication number: 20190368554
    Abstract: Disclosed herein are a clutch and a compressor including the same. The clutch includes a hub fastened to a rotary shaft of the compressor to be rotatable together with the rotary shaft in a state in which a position of the hub is fixed, a disk fastened to the hub to be rotatable together therewith, a pulley rotated by power transmitted from a drive source of the compressor, an elastic member for fastening the hub and the disk such that the disk is movable toward or away from the pulley with respect to the hub, a field coil assembly magnetized when electric power is applied thereto to allow the disk and the pulley to come into contact with or separate from each other, and an attenuation member interposed between the elastic member and the disk. Accordingly, it is possible to reduce noise and vibration due to contact and separation between the disk and the pulley by the elastic member and the attenuation member.

  • Publication number: 20080073175
    Abstract: In a power transmission apparatus for a compressor according to the present invention, a package of the compressor is reduced in size by shortening the longitudinal length of a one-way bearing while a predetermined level of transmission torque is sustained by optimizing the locations of the one-way bearing and a ball bearing module. Therefore, the mountability thereof can be improved. Also, the one-way bearing is disposed at an outer side from the ball bearing module in a radial direction so as to increase the number of rollers constituting the one-way bearing. Therefore, the transmission torque can be kept identically to that of the related art although the length of the one-way bearing is shortened.
