Title:
POWER TRANSMITTING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2010/147220
Kind Code:
A1
Abstract:
A power transmitting mechanism comprising: a first rotating body mounted to a rotating shaft of a drive device so as to be rotatable with the rotating shaft; a second rotating body configured so as to be rotatable with and relative to the first rotating body; an elastic body disposed between the first rotating body and the second rotating body and absorbing the rotational difference between the first rotating body and the second rotating body when the first and second rotating bodies rotate relative to each other; and switching section provided with a mass body mounted to one of the first and second rotating bodies so as to be rotatable therewith and also with a pressing member for pressing the mass body to the other rotating body, the switching section being configured in such a manner that, when the rotational frequency of the rotating shaft is less than or equal to a predetermined rotational frequency, the pressing force of the pressing member makes the mass body come in contact with the other rotating body to generate a frictional force between the contacting surfaces to thereby prohibit the relative rotation between the first and second rotating bodies, and when the rotational frequency of the rotating shaft exceeds the predetermined rotational frequency, the centrifugal force generated by the rotation of the rotating shaft makes the mass body displaced against the pressing force of the pressing member to separate the mass body from the other rotating body to thereby permit the relative rotation between the first and second rotating bodies through the elastic body.
