Abstract
Improvements in a torque limiter that uses a plurality of ball bearings that are retained in a cage. The ball bearings are compressed to create frictional drag on opposing flat plate surfaces. In some military vehicles the gun turret is rotated by personnel turning a crank that rotates the turret. The crank rotates a pinion or chain that turns the rack of the turret. When the turret does not move freely the personnel will typically apply more force that results in damaging the pinion, chain and or the rack. The torque limiter for a gun turret in this application connects between the crank and the drive train to allow the crank to turn without applying excessive torque forces on the pinion, chain and or the rack.
