摘要： A chain, wound to span between two pulleys each having facing conical surfaces able to change a distance therebetween and sandwiched by the facing conical surfaces, includes: link units each configured such that plate-shaped links, each having openings, are oriented in a chain circumferential direction and arranged in a chain width direction; and pins each extending through the openings of the links of the link units adjacent in the chain circumferential direction and each contacting the conical surfaces of sheaves at both ends thereof. A curvature radius of a shape curve representing a shape of each end face of each pin in a plane perpendicular to the chain circumferential direction is larger at an inner side in a pulley radial direction than at an initial contact point that is a contact point at the time when a load on each pin is 0.

摘要： Three links within one width-direction unit are included in respectively different link units. The links in the first row and the sixth row from the right end and the left end of a chain are included in the same link unit. The links in the second row and the fifth row are included in the same link unit. The links in the ninth row and the tenth row are included in the same link unit other than the link unit in which the links in the second row and the fifth row are included. With the above structure, the stress amplitude of the links forming a chain for a chain-type continuously variable transmission can be reduced.

摘要： Three links (40) within one width-direction unit (54) are included in respectively different link units (46). The links in the first row and the sixth row from the right end and the left end of a chain are included in the same link unit (first link unit 46-1). The links in the second row and the fifth row are included in the same link unit (second link unit 46-2). The links in the ninth row and the tenth row are included in the same link unit other than the link unit in which the links in the second row and the fifth row are included (first link unit 46-1 or third link unit 46-3). With the above structure, the stress amplitude of the links forming a chain for a chain-type continuously variable transmission can be reduced.

摘要： A chain is formed by coupling chain elements including plate-shape links arranged in the width direction of the chain and pins (42) extending through the links in the width direction of the chain, in the circumferential direction of the chain. The pin (42) is clamped between two opposing substantially conical surfaces 24 and 26 of a pulley (12). The deformation ratio of the pin length when the pin is clamped by the pulley is set to be 1.3×10−6 (1/N) or greater. The deformation ratio of the pin length is represented by (deformation ratio)=ΔL/(F×L), wherein L indicates a length of the pin, F indicates a load applied to the pin, and ΔL indicates a deformation quantity. Thus, noise of a chain-type continuously variable transmission in the frequency band of 3 to 5 kHz can be reduced.
摘要翻译：通过将链条沿链条的宽度方向布置的链条和在链条的宽度方向上延伸穿过链节的销钉（42）在链条的圆周方向上联接链条形成链条。销（42）被夹紧在滑轮（12）的两个相对的基本上圆锥形的表面24和26之间。当销被皮带轮夹紧时，销长度的变形率设定为1.3×10-6（1 / N）以上。销长度的变形率由（变形率）= DeltaL /（F×L）表示，其中L表示销的长度，F表示施加到销的负载，DeltaL表示变形量。因此，能够降低3〜5kHz的频带的链式无级变速器的噪声。
