High torque friction fit low moment hub joint assembly for a shaft

A hub joint assembly for frictionally connecting to a shaft of a first device, the hub joint assembly comprising:

• a coupling hub including a collar portion and a flange portion, wherein the collar portion includes a bore defining an inner surface that is configured to be positioned adjacent to an outer surface of the shaft, wherein the inner surface of the collar portion defines a keyway configured to receive a key defined on the shaft, wherein the collar portion further includes an outer surface, and wherein the flange portion extends from the collar portion to a terminal flange end;
• a clamp ring including a bore having an inner surface, wherein the inner surface of the clamp ring is configured to mate with the outer surface of the coupling hub, wherein the clamp ring further includes an outer surface and a terminal face surface, wherein a passage is defined in the clamp ring, wherein the passage extends from the outer surface of the clamp ring or the terminal face surface of the clamp ring to the inner surface of the clamp ring, and wherein the terminal flange end of the flange portion of the coupling hub extends beyond the outer surface of the clamp ring;
• and
• a connector having a first end, a second end and a side wall extending between the first and second ends, wherein the first end is secured to the flange portion of the coupling hub such that an open space is defined between the side wall of the connector and the outer surface of the clamp ring.
