Abstract:
1. A method of manufacturing a tripod constant-velocity joint having a tubular outer member coupled to an end of a transmission shaft and having a plurality of axially extending guide grooves defined in an inner circumferential surface thereof and spaced at predetermined intervals, a plurality of trunnions projecting respectively into said guide grooves, a ring-shaped roller engaging in each of said guide grooves and fitted over each of said trunnions, and a plurality of rolling elements rollingly interposed between each of said trunnions and said roller, said method comprising the steps of: providing first and second flanges on axially spaced opposite ends of an inner circumferential wall surface of said roller, said first and second flanges projecting radially inwardly and holding said rolling elements therebetween; and arranging all rolling elements except a plurality of remaining rolling elements along said inner circumferential wall surface of said roller, and then simultaneously pressing said remaining rolling elements radially outwardly respectively into circumferentially spaced gaps between adjacent ones of the rolling elements arranged along said inner circumferential wall surface.
