Abstract
A torque limiting mechanism includes an axial space formed in a cylindrical wall of a pulley, and a pin protruding and extending from a back surface of a discharge disc. The pin is inserted into the axial space, and a rubber damper is installed between the inner surface of the axial space and the pin. When torque difference between the pulley and the discharge disc exceeds a threshold, a root portion of the pin is broken to separate the discharge disc from the pulley, thereby interrupting rotation transmission from the pulley to the discharge disc.
Claims9
A rotation transmitter, comprising:
- a pulley including a cylindrical wall;
- and
- a hub rotating by receiving rotation force from said pulley, said hub including a torque limiting mechanism to interrupt rotation transmission from said pulley to said hub when a torque difference between said pulley and said hub exceeds a threshold, wherein
- said torque limiting mechanism is disposed within an axial dimension of said cylindrical wall;
- said torque limiting mechanism includes a break portion to be broken to interrupt the rotation transmission from said pulley to said hub when the torque difference between said pulley and said hub exceeds said threshold;
- said break portion is provided at a particular position where stress caused by torque transmission to said hub mainly acts;
- said rotation transmitter is used for a rotary machine;
- said rotation transmitter further includes a connection portion connecting to a rotating shaft of said rotary machine;
- and
- said connection portion is provided radially inwardly from said particular position.
