<p>A joint assembly is disclosed for connecting two spaced drive shafts (36, 38), such as in a submergible pumping system. The joint assembly comprises a connecting shaft (34) having enlarged bodies (40) on each end thereof, a housing (44) surrounding each enlarged body, each housing connectable to one of the drive shafts, lock devices (46, 48) for preventing relative rotational movement of the connecting shaft (34) with respect to the drive shafts (36, 38), and mechanisms (56,60,66; 56,60,64) within each housing acting upon the enlarged bodies (40) to bias the connecting shaft into coaxial alignment with the drive shafts. With this joint assembly lateral displacement or "wobble" of the drive shafts (36, 38) is permitted, yet the bias mechanisms (56,60,66; 56,60,64) tend to restore the drive shafts to coaxial alignment. <IMAGE></p> |
