動力伝達機構
Document Type and Number:
Japanese Patent JP4135632
Kind Code:
B2
Abstract:
In order to transmit a torque from a hub 5 (rotating body) integrally formed together with a pulley 4 to, for example, a sleeve 6 inserted under pressure into a rotating shaft 1 of a refrigerant compressor 2 , end surfaces 5 e and 6 a, which act as a bearing surface, are brought into frictional contact with each other. An axial pressing force is generated by the engagement of screws 1 a and 5 d of the rotating shaft 1 and the hub 5 . An annular cut-out part 7 , etc., is provided to form an annular space 10 in a part of the bearing surface around the rotating shaft 1 . Thereby, the equivalent diameter of the bearing surface is increased, a slip is more unlikely to occur on the bearing surface, and it is therefore no longer necessary to apply an excessive pressing force to obtain a large friction torque.
