    摘要： A power roller of a power roller bearing in a half-toroidal type continuously variable transmission is manufactured as follows. In step S1, a work used as material is heated up to a temperature suitable for forging. In step S2, the work is pressed by using a first die set, with its end face being held. In step S3, the work is forged by using a second die set. The work is formed into a work having a curved face corresponding to a traction surface, a hole corresponding to a center hole, and a recess corresponding to a raceway groove. In step S4, the work is punched by using a third die set. In step S5, the work is subjected to a cutting process and a heating process, thereby obtaining the power roller.

    摘要翻译： 如下制造半环型无级变速器中的动力滚子轴承的动力辊。 在步骤S1中，将用作材料的工件加热至适于锻造的温度。 在步骤S2中，通过使用其端面保持的第一模具组来按压工件。 在步骤S3中，通过使用第二模具组件来锻造工件。 工件形成为具有与牵引面对应的曲面，与中心孔对应的孔和对应于滚道槽的凹部的工件。 在步骤S4中，通过使用第三模具冲压工件。 在步骤S5中，对作业进行切割处理和加热处理，从而获得动力辊。
