Abstract: Disclosed are a method of manufacturing cage for a constant velocity joint and a cage for a constant velocity joint manufactured using the same for providing a cage having improved hardness, strength, and elongation while having a structure with a uniform core part and surface and for ensuring economic feasibility by reducing manufacturing time. The method includes a cutting operation of forming a structure having an outer shape by cutting a cylindrical pipe, forming an outer circumference of the cut structure to have a curved surface thereon, performing a turning operation on a surface of the formed structure, a punching operation of forming a window in the surface of the structure on which the turning operation is performed, a broaching operation of processing an edge of the window formed via punching, and a heat treatment operation of fully hardening the completely broached cage via austempering.

Abstract: A method for manufacturing a trunnion for a constant velocity joint, the trunnion having a plurality of journal units provided outside around a hub unit, the method including a first step of manufacturing the trunnion, a second step of thermally treating a rounded outer circumferential surface of the journal unit, and a third step of thermally treating a connection unit disposed between the journal unit and the hub unit and having a diameter smaller than that of the journal unit.

Abstract: In a CV joint-bearing mounting structure, a steering unit, including a CV joint and a bearing, is engaged with a knuckle via tapered portions, a first nut is mounted to the outer end of the bearing, a disk is engaged with an engagement part of the CV joint via toothed portions, and a second nut is mounted to one end of the CV joint. The quality of the bearing is improved, the tolerance of the assembled components is reduced, and the types and number of the components are reduced, thereby improving the efficiency of assembly of the components.

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.
