    • A durable V-belt formed by fastening plate-like elements juxtaposed annularly using a ring. The element comprises a saddle face on which the ring is disposed, columns extending radially outwardly from lateral ends of a saddle face, and flank faces formed on lateral ends of the column to be contacted with a groove of a V-pulley to transmit power. An angle between outer circumferential portions of the flank faces is substantially identical to or smaller than an open angle of the groove of the V-pulley; and an angle between inner circumferential portions of the flank faces is larger than the angle between the outer circumferential portions.
    • 一个耐用的V形皮带,通过使用环形环状平行地固定板状元件而形成。 该元件包括一个鞍形面,环上设置有鞍形面,从鞍面的横向端部径向向外延伸的柱,以及形成在柱的横向端部上的与U形皮带轮的槽接触以传递动力的侧面。 侧面的外周部之间的角度与V形带轮的槽的开度角大致相同或相等; 并且所述侧面的内周部之间的角度大于所述外周部之间的角度。
