A continuously variable, conical disk transmission including a torque-transmitting member in the form of a plate-link chain or a thrust link band. The chain includes plate links that are interconnected by pairs of rocker members that extend transversely relative to the chain movement direction. The thrust link band includes a number of thrust links that are in face-to-back contact and that extend transversely relative to the band movement direction. Each of the rocker members and the thrust links have ends that contact surfaces of the conical disks of the transmission for transmitting torque between the sets of disks. The ends of the rocker members and of the thrust links have a carbon-nitrided outer layer having a thickness of at least about 50 &mgr;m for increased durability. The surfaces of the conical disks that are contacted by the chain or the thrust link band can also be similarly treated.

Plate-link chain

A method of producing a rolling bearing race provided with a continuous rupture seam along at least one area of its periphery and having a seating surface and a race for rolling elements, the rolling bearing race surface being exposed before rupture along at least a portion of the intended course of the rupture seam to high-energy radiation with the local confines transerve to the intended course of the rupture seam and during rupture the surface area exposed to radiation is subjected to tensile stress by an external force, characterized in that the seating surface (2,8) of the bearing race (1,7) is exposed to the radiation and the external force is exerted as a pressure force onto the raceway surface (3,9) along an area directly opposed to the area (6,10) of the seating surface (2,8) exposed to radiation.
