  • Geared motor
    Patent number: 6577034
    Abstract: A spline is provided on a hollow shaft, and the key in the spline can couple directly a shaft to be driven of an external apparatus. Screw blocks rotational torque, thus screw is desirably located as far as possible from output shaft. Although the location is not illustrated, an anti-revolving function is desirably provided on the housing surface at the farthest place from the output shaft so that less force is required for fixedly securing the geared motor.

  • Torque reducer and torque transmitter including the same
    Patent number: 6302798
    Abstract: A torque transmitter includes (a) a driver, (b) torque transmitting means for transmitting the torque generated by the driver to a follower, (c) a rotary body on the follower side, and (d) a torque reducer that reduces (or discontinues) the torque transmission when excessive torque over a threshold torque value is loaded to the rotary body on the follower side, and the torque limiter has different threshold-torque-values responsive to rotating directions of the rotary body.
