QUICK RELEASE DOWNHOLE MOTOR COUPLING Abstract of the Invention An improved quick release coupling assembly for a drive shaft of a downhole motor is disclosed. The quick release coupling has an internally tapered collar to cause the mating taper on the outside surfaces of the clutch dogs to be held firmly by the collar and in intimate engaging relationship between the mating tapered surfaces. The angle of the mating tapered surfaces is greater than a self- locking angle so that the quick release feature permits easy disassembly of the joint, and thus the tool, on the rig floor or as well as in the shop.
