Abstract
A structure for a tripod constant velocity joint and a method of assembling a roller assembly maintains the structural stability of the tripod constant velocity joint, and minimizes the frictional force between a trunnion and a track, thus remarkably reducing the generation of axial force, therefore ensuring the stable operation and durability of the constant velocity joint. The structure for the tripod constant velocity joint includes an inner roller and an outer roller provided between a track of a housing and a trunnion of a spider. A roller groove is formed on a central portion of an outer surface of the outer roller in a circumferential direction of the outer roller. Further, a plurality of recesses is formed on a surface of the trunnion to reduce a contact area with the inner roller.
