Ring latch locking shaft coupling for bi-directional loading

A coupling assembly adapted to connect a first shaft with a second shaft, the coupling assembly comprising:

• a coupling cylindrical in shape with splines formed longitudinally along an inner surface;
• a thrust pin generally cylindrical in shape with an alignment feature and a retainer groove on an outer surface of an upper portion;
• a retainer bore extending into the first shaft comprising a retainer groove and a retaining ring;
• a pin bore extending into the second shaft;
• wherein a lower portion of the thrust pin is coupled with the pin bore of the second shaft;
• wherein the alignment feature on the thrust pin is configured to align the retainer groove on the thrust pin with the retainer groove within the retainer bore;
• and
• wherein the thrust pin is configured to transfer tensile stress from the first shaft to the second shaft by the retaining ring installed between the retainer bore of the first shaft and the retainer groove in the thrust pin.

A system, comprising:

• a first section comprising a first housing and a first drive shaft;
• a second section comprising a second housing and a second drive shaft;
• wherein the first and second housing are cylindrical in shape with an inner chamber, and wherein the first and second drive shaft are cylindrical in shape;
• wherein the first housing is configured to mechanically couple to the first housing, the second housing, or combinations thereof;
• a coupling assembly comprising an upper shaft, a lower shaft, a coupling, and a thrust pin, wherein the upper shaft is generally cylindrical in shape with splines formed on an outer surface and a retainer bore comprising a retainer groove and a retaining ring, wherein the lower shaft is generally cylindrical in shape with splines formed on an outer surface and a pin bore, wherein the coupling is generally cylindrical in shape with splines formed longitudinally along an inner surface, wherein the thrust pin is generally cylindrical in shape with a retainer groove on an outer surface of an upper portion;
• and
• wherein the coupling assembly is configured to transfer tensile stress from the upper shaft to the lower shaft by the retaining ring installed between the retainer bore of the upper shaft and the retainer groove in the thrust pin.
