ABSTRACT:
A disengageable friction coupling is comprised of a hollow shaft having a tapered inner surface. An element defining an internal opening is mounted over the hollow shaft, the hollow shaft having a tapered inner surface in the region of said element. A plug is located inside the hollow shaft in the region of the element. The plug has a tapered outer surface which mates with the tapered inner surface of the hollow shaft. The tangent of the angle of taper is less than the coefficient of static friction between the mating surfaces of the plug and the shaft. A double-acting ram is mounted on the shaft and on the plug so that, when the ram drives in one direction, it presses the plug into the shaft so as to substantially elastically deform the shaft radially outward for frictional engagement with the element, and, when the ram drives in the opposite direction, it pulls the plug outward, allowing the shaft to return substantially to its normal, unstressed shape, and thereby releases the shaft from frictional engagement with the element.
