ABSTRACT:
In a quick disconnect between a driving shaft and a driven shaft, in which a first annular bracket is mounted on an end of the driving shaft and a second annular bracket is mounted on an end of the driven shaft facing the first bracket but spaced substantially from the first bracket, each of the brackets having radially inwardly, axially extending splines, and a spool having annular flanges at each axial end extending radially outwardly and having radially outwardly extending splines complementary to the inwardly extending bracket splines, the spool having an annular channel defined by spaced radially outwardly extending annular walls, a yolk is provided having two substantially diametrically opposite, radially outwardly extending arms and a roller-carrying section connected to the arms, the roller-carrying section extending around the channel and extending radially between the channel walls and carrying two, diametrically opposed rollers within the channel the rollers projecting axially beyond sides of the roller-carrying section to permit the rollers selectively to be forced into engagement with one or the other of the channel-defining walls, the arms extending radially beyond the reach of the brackets, and the arms being operatively connected to spool shifting cylinder and piston assemblies, the cylinder and piston assemblies being positioned radially outboard of the brackets.
