CONSTANT VELOCITY JOINT AND INSTALLATION ABSTRACT An improved constant velocity joint is disclosed which is embodied in a constant velocity joint (10) for specific use in connecting a yoke (14) to a mast (12) in a helicopter and in a constant velocity joint (200) for interconnecting a first shaft (202) to a second shaft (204) for bidirectional drive. The constant velocity joint employs a carrier (40, 218) which is formed with a series of apertures for receiving elastomeric bearing assemblies (42, 80, 220). The elastomeric bearing assemblies are provided with a spherical elastomeric bearing (60) and a cylindrical elastomeric bearing (48). Certain of the elastomeric bearing assemblies connect the carrier to one of the rotated members while the remaining elastomeric bearing assemblies connect the other rotating member to the carrier. The axis of symmetry of the carrier (68) will always bisect the angle of misalignment between the two rotating shafts or members to assure that a constant velocity joint is achieved.
