ABSTRACT:
A constant velocity joint for a drive system having a first rotating shaft and a second rotating shaft, wherein the constant velocity joint comprises: a hollow housing fixed to an end of the first rotating shaft, an inner face of the housing including a plurality of guide grooves extending in an axial direction of the housing, each groove having a pair of opposing side faces; and a tripod disposed at an end of the second rotating shaft, having a plurality of trunnions each positioned in a corresponding one of the guide grooves; and, an inner roller mounted to an outer end portion of each of the trunnions, an outer roller mounted on an outer face of each inner roller with needle rollers engaged between the inner and outer rollers for transmitting a load between the first and second rotating shafts to drive the driving system. Each trunnion includes an at least partially spherical surface in a circumferential area subjecting to the load, and a cylindrical protrusion disposed at the at least partially spherical surface and protruded to a distance from the at least partially spherical surface in a direction normal to the axis of the respective trunnion for surface-to-surface contact with an at least partially spherical inner face of the respective inner roller while defining a gap around the cylindrical protrusion and between the at least partially spherical surface of the respective trunnion and the at least partially spherical inner face of the respective inner roller.
