Patent ID: 11815139

Abstract:
Unlaminated bearings (or Torque Transfer Elements, or TTEs) are disposed to slide and displace within pockets (or “housing cavity receptacles”) provided in the internal periphery of a housing in which an articulating shaft is received. As the shaft “tilts” about its untilted axial centerline during misaligned rotation, convex curved bearing surfaces on shaft pins slidably rotate against corresponding concave curved bearings surfaces on the T as received in the housing cavity receptacles. Further, substantially flat surfaces on the TTEs are disposed to slidably displace against corresponding bearing surfaces on the housing cavity receptacles as the shaft tilts and the convex curved bearing surfaces on the shaft pins slidably rotate against the concave curved bearing surfaces on the TTEs. The sliding displacement of TTEs with respect to the housing cavity receptacles during articulated rotation is in a direction generally parallel to the shaft's untilted axial centerline.
