  • TRIPOD CONSTANT VELOCITY JOINT AND METHOD OF PRODUCING THE SAME
    Publication number: 20150024855
    Abstract: A roller includes: an outer peripheral rolling contact surface which is shaped by a simultaneous process in a state where end faces of a plurality of rollers are in contact with each other; and a protrusion which is axially protruded further than an axial end of the outer peripheral rolling contact surface. The protrusion has a protruded end face which, when the outer peripheral rolling contact surface is ground, is in contact with the end face of one of the rollers which are adjacent to each other, and forms an axial gap between ends of the outer peripheral rolling contact surfaces of the rollers which are adjacent to each other, in a state where the protruded end face is in contact with the end face. The protrusion further has a gap with respect to a tool when the outer peripheral rolling contact surface is processed.
