ABSTRACT:
A brake stop for limiting the rotation of a rotating member to a predetermined amount comprises a brake which is actuable for stopping rotation of the rotating member and an actuator mechanism responsive to the rotation of the rotating member for actuating the brake after a predetermined amount of rotation of the rotating member. The actuator mechanism includes a differential counter gear set and a ball-ramp mechanism which converts rotary motion of the rotating member by way of the differential counter gear set into linear motion for actuation of the brake. Provision is made for sufficient lost motion or backlash in the differential counter gear set upon reversal of gear rotation to allow release of the brake from a braked condition upon reversal of the direction of rotation of the rotating member.
