20080232979 | Compressor - A swash plate compressor ( | 09-25-2008 |
20080236979 | Power transmission apparatus - A power transmission apparatus comprising a pulley | 10-02-2008 |
20080305905 | Hub for power transmission apparatus - A hub for use in a power transmission apparatus comprises cylindrical portion | 12-11-2008 |
20080314709 | Power transmission apparatus - A power transmission apparatus comprises a pulley mounted rotatably on a casing of a rotary device, a hub coupled to the pulley by fitting between depressions and protrusions, a power shutoff member for preventing excessive torque between a rotary shaft and the hub, and an engaging device for engaging the hub and the pulley each other. The engaging device includes a first stepped portion formed radially on the outer periphery of the hub and a second stepped portion formed radially on the inner peripheral wall of a rim of the pulley in such a manner as to engage the first stepped portion in the axial direction. | 12-25-2008 |

20110127136 | CLUTCH MECHANISM - A clutch mechanism includes a pulley, an armature, an electromagnet, a plate spring, and a damper. The armature is joined to the pulley in a direction of a rotation axis. The electromagnet generates attracting magnetic force, which attracts the armature in a joining direction. The plate spring generates resilient force, which urges the armature in an opposite direction from the joining direction. The damper includes an impact mitigation part mitigating an impact when the armature collides with the pulley. The pulley, the armature, the damper, and the plate spring are arranged in this order in the direction of the rotation axis. The damper includes a contact portion in contact with part of the armature in the direction of the rotation axis. The plate spring includes a pressing part pressing the contact portion on the armature both at time of joining and at time of unjoining between the armature and the pulley. | 06-02-2011 |
20150292573 | CLUTCH - A recess, which has a bottom, is formed in at least one of a contact surface of a rotor and a contact surface of an armature. A solid material, which is made of thermoset resin that contains powder of metal oxide or metal dispersed in the thermoset resin, is formed in an inside of the recess. | 10-15-2015 |
