ABSTRACT:
A coupling device for connecting an externally splined shaft having a circumferential groove therein to an internally splined member. The internally splined member has a plurality of radial openings in the sides thereof which receive a corresponding plurality of balls for protrusion between the splines in the groove in the externally splined shaft. A twist collar is positioned on the internally splined member and is rotatable through a predetermined angle. The twist collar has cam structure extending around the interior periphery with a plurality of dwells at spaced locations corresponding to the plurality of radial openings in the sides of the internally splined member. An inclined cam surface interconnects two adjacent dwells and is positioned to engage one of the balls during rotation of the twist collar to force the one ball into the groove in the externally splined shaft. A torsion spring connects the internally splined member and the twist collar and is constructed for rotation through the predetermined angle. The coupling device is normally in its locked position and is rotatable by an operator to an open position for installation of the internally splined member with respect to the externally splined shaft.
