Abstract
A brake to decelerate the driving movement of an actuating rod along an axis. The actuating rod is driven relative to a frame by an actuating mechanism. The actuating rod has an external tapered surface whose lateral dimension decreases in the direction in which it is driven. The brake includes a case attachable to the frame which contains within it a peripheral cylindrical brake band and a wedge member. The wedge member has an outer wall, and a tapered inside wall with substantially the same taper angle as the actuating rod. The wedge member and the brake member are disposed inside a passage in the case, with the brake band disposed between the case wall and the wedge member. There is a spacing between the wall of the passage and the outer wall of the brake band. The tapered inside wall is axially aligned with at least a portion of the inside wall of the brake band. When the tapered surface on the actuating rod enters the tapered inside wall, it presses the wedge member against the brake band and the resulting hoop-expansion of the brake band exerts a restraining force on the actuating rod so as to decelerate and arrest its motion.
