ABSTRACT:
This disclosure relates to a torque limiter for use in connecting a rotational drive to a part to be driven. The limiter includes a drive member adapted to be connected to the drive, a driven member adapted to be connected to the part and rotatable relative to the drive member, a clutch roller connected to the drive member and movable to an engaged position where it couples the drive and driven members and to a disengaged position where the driven member is uncoupled from the drive member, the driven member producing a reaction force on said clutch roller during the application of torque which tends to move the clutch roller to the disengaged position, a clutch member that is angularly movable relative to the drive member and is engageable with the clutch roller, the clutch member being angularly movable to a first position where it moves the clutch roller to its engaged position and to a second position where it permits the clutch roller to move to the disengaged position due to the reaction force, and adjustable force means connecting the clutch member to the drive member and tending to move the clutch member to the first angular position. At the upper torque limit, the reaction force is high enough that it overcomes the force means and moves the clutch member to the second position and the clutch roller to the disengaged position.
