Shaft coupling alignment device

A coupling for attaching a pair of longitudinally aligned, rotatable shafts comprising:

• a) pair of circular hubs having an inner flat surface and an outer surface, each hub having a bore through a central axis thereof;
• means for fixing a shaft within each bore;
• a plurality of rounded coupling pins extending outwardly from the inner surface;
• b) a circular power ring positioned between the hubs;
• said ring having front and rear flat surfaces;
• a plurality of circular apertures extending through and spaced around the power ring;
• a hollow bushing positioned in each circular aperture;
• each of said coupling pins being, mounted within a corresponding one of the hollow bushings and wherein the circular power ring is free floating with respect to each hub.

A process for attaching a pair of longitudinally aligned, rotatable shafts comprising:

• i) providing a coupling comprising:
• a) a pair of circular hubs having an inner flat surface and an outer surface, each hub having a bore through a central axis thereof;
• means for fixing a shaft within each bore;
• a plurality of circular apertures through and spaced around each hub;
• a hollow bushing positioned in each circular aperture;
• b) a circular power ring positioned between the hubs;
• said ring having front and rear flat surfaces;
• a plurality of rounded coupling pins extending outwardly from each of the front and rear surfaces, and wherein the circular power ring is free floating with respect to each hub;
• ii) attaching a two shafts to said coupling, one shaft being attached to each circular hub through each bore;
• iii) mounting each of said coupling pins within a corresponding one of the hollow bushings.
