摘要： A method of producing a cam lobe piece of an assembled camshaft in a valve operating system for an internal combustion engine. The method comprises (a) forming a profile of the cam lobe piece by upsetting a material under forging to obtain an intermediately formed body; (b) piercing a central portion of the intermediately formed body to form a shaft bore; and (c) ironing an inner peripheral surface of the pierced intermediately formed body to form unevenness at the inner peripheral surface, all accomplished by cold working. The material at the forming the profile of the cam lobe piece has a first section located on a side of a cam nose of the cam lobe piece, and a second section located longitudinally opposite to the first section. The material has a thickness which gradually increases in a direction from the second section to the first section.

摘要： A pulley useable with a driving belt in a continuously variable transmission, including a moveable pulley half having an integral cylinder portion integrally formed therewith by plastic working. The moveable pulley half includes an axially extending hollow shaft portion, a radially outwardly extending flange portion having a contact surface frictionally contacted with the driving belt, and the integral cylinder portion axially extending at near an outer peripheral portion of the flange portion. The plastic working includes forming a workpiece, machining the workpiece, spinning the workpiece to form the integral cylinder portion, heat-treating the workpiece and finishing the workpiece to complete the moveable pulley half.
