摘要： A silent chain is constituted by a number of articulately connected link plates each having an engagement surface for meshing engagement with teeth of a sprocket. The link plates are press-formed so that the engagement surface includes a smooth sheared surface. All of the link plates have respective sheared surfaces along not more than 60% of the thickness of the link plates. In order to reduce noises produced when the link plates mesh with the sprocket teeth, more than 50% of the link plates have respective sheared surfaces along 7 to 15% of the thickness of the link plates and are arranged randomly in the silent chain.

摘要： Each link plate of a low noise silent chain has an inside meshing surface formed on the inside flank of each link tooth. The inside meshing surface includes a convexly arcuate mesh start portion disposed on a tip side of each link tooth, and a convexly arcuate mesh guide portion disposed on a root side of each link tooth. The arcuate mesh guide portion has a radius of curvature and a circular arc length which are greater than a radius of curvature and a circular arc length, respectively, of the convexly arcuate mesh start portion. When the silent chain engages a sprocket, the engagement proceeds smoothly and continuously from the inside meshing surface to the outside meshing surface. This contributes to the reduction of the noise level of the silent chain as a whole through suppression of meshing sound of the outside meshing surface and vibratory chain noise.
摘要翻译：低噪声无声链的每个链板具有形成在每个连杆齿的内侧面上的内啮合表面。内部啮合表面包括设置在每个连接齿的末端侧的凸起的弓形网格起始部分和设置在每个连接齿根部侧的凸形弓形网状引导部分。弧形网状引导部分具有分别大于凸弧形网格开始部分的曲率半径和圆弧长度的曲率半径和圆弧长度。当无声链与链轮接合时，接合从内啮合表面平滑地连续地进入到外啮合表面。这有助于通过抑制外啮合表面的啮合声和振动链噪声来整体降低无声链的噪声水平。

摘要： A silent chain for use with a sprocket has a plurality of interleaved rows of link plates connected together in an endless fashion, each link plate having a pair of teeth. Each of the teeth has an inside flank and an outside flank surface merging at a tip of the tooth. The inside flank has a smooth contact surface which is smaller in width than the smooth contact surface of the outside flank surface. The point where the link plate starts to move into contact with the tooth flank of the sprocket is set to locate in an area having the smooth contact surface at a relatively high rate of occupancy. With this arrangement, noise occurring at the mesh between the link plate and the sprocket can be reduced. The point where the meshing engagement completes is set to locate in an area having the smooth contact surface at a relatively high rate of occupancy. This arrangement improves the wear resistance and fatigue strength of the link plate.

摘要： In a transmission comprising an endless silent chain and a sprocket the inside tooth faces of the link plates of the chain are identical to tooth profiles, arranged axially, of a hob cutter for forming teeth of the sprocket. The inside and outside tooth faces also satisfy Hi=Ho+Hs, where Hi is the distance from a pin center line Lp to a pitch line Li of the inside tooth faces, Ho is a distance from the pin center line to a pitch line Lo of the outside tooth faces, and Hs is the amplitude of polygonal motion of the chain. Each link plate also has a concave bottom surface between its teeth to avoid interference with edges of the involute teeth arising due to the chain polygonal motion amplitude when the outside tooth faces are brought into meshing engagement with the involute teeth and become seated thereon.

摘要： A rocker pin for use in a power transmission chain has an identifying mark for distinguishing the rocker pin from another rocker pin having a different thickness or a different rocker surface. The identifying mark may include a groove, ridge, colored mark, lustrous streak or the like provided on a peripheral surface except a rocker surface in the longitudinal direction of the rocker pin. The rocker pin having such identifying mark can be visually identified with ease so that the rocker pin is prevented from being mixed with a different kind of rocker pins. This enables easy and confusion-free storage of the rocker pin and prevents incorrect combination of a longer pin and a shorter pin, which may occur when they are used in combination to form a single rocker joint.

摘要： A silent chain includes guide link rows and joint link rows arranged alternately and articulately connected in an endless fashion by rocker joint pins each composed of a longer pin and a shorter pin. In each guide link row, the longer pin is fitted with two guide plates and also inserted through link plates disposed between the guide plates. In each joint link row, the shorter pin is inserted through link plates. The longer pin and the shorter pin are initially formed in a straight configuration and have the same cross-sectional shape. When the silent chain is stretched substantially straight after having been subjected to a proof load, the pitch of the guide plates is made slightly greater than the pitch of adjacent contact points between the longer pins and the shorter pins of the rocker joint pins in the guide link rows so that the longer pins are elastically deformed into a bow-like configuration bent toward the mating shorter pins. The rocker joint pins having the elastically deformed longer pins acquire spring or cushioning properties which are effective to improve the strength of the chain and reduce the operation noise of the silent chain.
摘要翻译：无声链包括交替地布置的引导链节排和关节链节列，并且通过每个由较长销和较短销构成的摇臂关节销以无限制的方式铰接连接。在每个导向连杆列中，较长的销装配有两个导板，并且还通过布置在导向板之间的连接板插入。在每个接头连接列中，较短的销通过链板插入。较长的销和较短的销最初形成为直的构造并且具有相同的横截面形状。当无声链在受到证明载荷之后大致直线地拉伸时，引导板的间距略大于引导件中的较长销和摇臂接头销的较短销之间的相邻接触点的间距连接行，使得较长的销弹性变形成向配合的较短销弯曲的弓状构造。具有弹性变形的更长销的摇臂接头销获得弹簧或缓冲性能，这有助于提高链条的强度并降低无声链的操作噪音。

摘要： A rocker joint silent chain includes rocker joints articulately connecting together multiple interleaved link plates and guide plates located outside the interleaved link plates in the widthwise direction of the chain. Each of the rocker joints is composed of a longer pin firmly fitted at opposite ends thereof in a pair of aligned pin-accommodation holes of two opposed guide plates, and a shorter pin having opposite ends projecting from opposite outer surfaces of the interleaved link plates. The ends of the shorter pin are in slight contact with inner surfaces of the guide plates. High-frequency noise and abrasive wear of the rocker joints and link plates, which may occur due to free movement of the shorter pin in the widthwise direction of the chain, can be avoided.

摘要： A chain includes a pair of rocker joint pins inserted through laterally aligned pin holes of two adjacent link plates. The pin holes have a pair of upper and lower pin-position constraining surfaces arranged to face upper and lower flat surfaces, respectively, of each rocker joint pin with a very small clearance defined therebetween so that the rocker joint pin is always kept in position against displacement in a vertical direction relative to the link plates. When the chain is urged to warp or bend into a V shape, each of the rocker joint pins is gripped by the upper pin-position constraining surface of one of the two adjacent link plates and a warp blocking surface of the other of the two adjacent link plate. Thus, such warping of the chain does not take place.

摘要： A silent chain includes guide links and articular links arranged in the longitudinal direction of the chain. The guide links each include one or more guide link plates, and the articular links each include two or more articular link plates. When the chain is in the straight-line state, the inside flank of each meshing tooth of any one of the link plates projects outwardly from the outside flank of each meshing tooth of another laterally adjacent one of the link plates. The projecting length of the inside flank relative to the outside flank is allowed to vary between the adjacent links, either in a random fashion or in a regular alternate fashion, along the length of the chain. By thus providing different projecting lengths of the chain's inside tooth flanks, the sliding engagement start time of sprocket teeth relative to the inside tooth flanks of the individual link plates is allowed to vary between the adjacent links, so that the periodic meshing sounds can be prevented from resonating to get louder, with the result that the overall noise level can be minimized.
摘要翻译：无声链包括沿链条纵向布置的导向连杆和关节连杆。引导连杆各自包括一个或多个引导连接板，并且关节连接件各自包括两个或更多个关节连杆板。当链条处于直线状态时，任何一个连接板的每个啮合齿的内侧面从另一横向相邻的一个连接板的每个啮合齿的外侧面向外突出。允许内侧面相对于外侧面的突出长度在相邻链节之间沿着链的长度以随机方式或以规则的交替方式变化。通过这样提供链的内侧齿面的不同突出长度，链轮齿相对于各个链板的内侧齿面的滑动接合开始时间被允许在相邻链节之间变化，从而可以防止周期性啮合声音从共鸣到更大声，结果可以将整体噪声水平降至最低。

摘要： A wear-resistant silent chain includes a large number of link plates articulately connected together in an endless fashion by rocker joint pins each composed of a long pin and a short pin. The long and short pins have an outer peripheral surface formed by, at least, a convexly arcuate rocker surface which is adjacent to the convexly arcuate rocker surface of another pin, a load-bearing surface on the side opposite to the rocker surface and being seated on an inner peripheral surface of each of a pair of pin holes formed in each link plate, and a pair of lubricant guide surfaces each extending substantially linearly from one circumferential end of the load-bearing surface to an adjacent circumferential end of the rocker surface while extending divergently with respect to the inner peripheral surface of each of said pin holes. The lubricant guide surface provides a large lubricant collecting area which is sufficient to lubricate the load-bearing surface with an enough amount of lubricating oil and thereby prevents local wear caused between the inner peripheral surface of each pin hole and the load-bearing surface of each pin.
