Abstract
PURPOSE: To protect a working device by disconnecting a power source when abnormal torque is generated, by converting generated torque into motion in the axial direction proportional to the torque values.
CONSTITUTION: The turning effort of a motor 4 is transmitted to an output shaft 1 of a working device through a worm shaft 3 and a worm gears 2. The worm shaft 3 is integrally formed with a shaft of the motor 4, and motion in the axial direction is supported by a casing through springs 5, 5'. A rack gears portion 31 is mounted to a nose of the worm shaft 3, and engages with a pinion gears 6 for conversion transmitting motion in the axial direction of the worm shaft 3 to a main shaft 7 of a torque switch mechanism as rotary displacement.
