ABSTRACT:
A shaft coupling including a first gear on an end of a first shaft, a second gear on an end of a second shaft meshing with the first gear, a tubular sleeve around the meshing first and second gears, a universal thrust bearing between the tubular sleeve and the first shaft, and a self-locking linear retainer between the tubular sleeve and the second shaft. The self-locking linear retainer includes a cylindrical bushing attached to the second shaft, a plurality of windows in the tubular sleeve, and a plurality of resilient barbs on the cylindrical bushing which are flexed inward when the end of the second shaft having the second gear thereon is plugged into the tubular sleeve and which resiliently expand into the windows to prevent dislodgment of the second shaft from the tubular sleeve. The universal thrust bearing includes a spherical shoulder on the first shaft, a bearing ring seated on the spherical shoulder, an annular washer seated on a plurality of dimples on the tubular sleeve, and a spring compressed between the bearing ring and the washer which concurrently thrusts together the bearing ring and the spherical shoulder and the first and the second gears.
