摘要： The present invention improves accuracy in the axial dimension of rolled parts for a chain such as bushings, rollers and similar. A rolled part is manufactured by cutting a strip of steel into a rectangular shape to obtain a rectangular base material having a predetermined dimension, The rectangular base material is rolled into a clindrical shape to obtain a cylindrically formed part having cut end surfaces face each other. A core is inserted for rolling the rectangular base material into the cylindrically formed part. The cylindrically formed part is then pressed through a die having a circular opening. The rolled part has a plurality of blind grooves on a surface thereof. While the cylindrically formed part is being pressed through the die having a circular opening, a plastic flow of the material of the cylindrically formed part intensively occurs in a direction toward the blind grooves. Since the plastic deformation of the rolled part is absorbed by the blind grooves, axial dimension of the rolled part hardly varies,

摘要： An improved friction drive chain especially for a continuously variable transmission has a plurality of friction plates, each of the friction plates being substantially I-shaped in lateral section. The friction plates are arranged adjacent one another and connected by connecting link elements received in recesses formed in both lateral sides of the friction plates between upper and lower beam members of said friction plates. The connecting link elements are laterally grooved to bear longitudinally against the friction plates. The outer surfaces of the lower beam members of the plates define friction drive surfaces for contact with driving and/or driven pulleys. The friction plates are heat treated to increase strength, for example by quenching and annealing. The friction drive surfaces are formed with hardened layers by surface hardening treatment such as by electron beam or laser.

摘要： An improved rocker joint pin type CVT chain has link plates connected by rocker joints, each including a rocker pin and a seat pin in an insertion bore of the link plate, the rocker pin and the seat pin making rolling contact along opposing rolling arcuate surfaces thereof as the chain bends and straightens when passing around a pulley. At respective minimums, the sectional area of the link plate formed between the link plate insertion bore and the outer periphery of the link plate relative to the pulley, is greater than the sectional area formed between the link plate insertion bore and the inner periphery. The radii of curvature of the inner rolling contact surfaces of the rocker pin and seat pin are smaller than those of the outer rolling contact surfaces. The fatigue strength at the minimum sectional area portions is thereby increased and the deviation from the chain center line of the contact point of the opposing rolling contact surfaces is minimized in a straightened position of the chain, thereby reducing the load applied to the inner minimum sectional area portion.
摘要翻译：一种改进的摇臂接头销式CVT链条具有通过摇臂接头连接的连接板，每个链板包括在连杆板的插入孔中的摇杆和座销，摇杆销和座销沿相对的滚动弓形表面进行滚动接触当链条绕过滑轮时弯曲和拉直。在相应的最小值处，形成在链板插入孔和连接板的外周之间的链板相对于皮带轮的截面积大于在链板插入孔和内周之间形成的截面面积。摇杆销和座销的内滚动接触面的曲率半径比外滚动接触面的曲率半径小。因此，在链条的拉直位置上，最小截面积部分处的疲劳强度增加，并且相对的滚动接触面的接触点的链中心线的偏离最小化，从而减小施加到内部最小部分区域部分。
