  • the present invention relates generally to joint assemblies for operatively coupling rotating parts. More specifically, the present invention relates to joint assemblies comprising multiple joint members with one of the joint members having a centering flange for mounting to one of the rotating parts.
  • a typical CV joint comprises a first joint member for mounting to a first rotating part and a second joint member for mounting to a second rotating part.

  • tolerances between the centering flange and the second rotating part can be increased.
