Universal joints and methods of manufacture

A mechanical joint for transferring rotational motion from a first shaft to a second shaft, comprising:

• a housing, the housing having a first open end and a second end;
• a first drive puck disposed in the first open end, the first drive puck comprising a first wing joined with a second wing by a connecting region, an inner slot, and a circular outer perimeter having an outer contact surface extending across the first and second wings and the connecting region;
• a first drive shaft coupled with the first drive puck, the first drive shaft comprising a first end and a second end, the first end pivotably coupled within the inner slot of the first drive puck by a first pin, the second end configured to couple with the first shaft;
• wherein the first and second wings of the first drive puck each comprise an inner planar surface forming the inner slot, and the first end of the first drive shaft comprises first and second opposite planar surfaces slidingly engaged with the inner planar surfaces, respectively;
• wherein the first drive shaft rotates in a first plane with respect to the housing about the first pin and rotates in a second plane with respect to the housing on the first puck;
• a first channel disposed in the first open end;
• and
• a first cap ring comprising a central opening and first and second channel segments, the first cap ring coupled with the first end of the housing with the first drive puck disposed within the first channel and the first and second channel segments, the outer contact surface of the first drive puck slidingly engaged with a bottom surface of the first channel, and the second end of the first drive shaft extending through the central opening of the first cap ring.
