    • 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.
    • 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。

    • 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.
    • 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。

    • 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.
    • 耐磨无声链包括大量连接板,它们通过各自由长销和短销组成的摇臂接头销以无限制的方式连接在一起。 长销和短销具有外周表面,该外周表面至少形成为凸形弓形的摇杆表面,其与另一销的凸弧形摇臂表面相邻,在与摇臂表面相对的一侧上的承载表面并且坐着 在每个链板中形成的一对销孔的每一个的内周面上,以及一对润滑剂引导表面,每个润滑引导表面基本上从承载表面的一个周向端部延伸到相对的摇臂表面的周向端部, 相对于每个所述销孔的内周表面发散。 润滑导向面提供了大量的润滑剂收集区域,其足以用足够量的润滑油润滑承载表面,从而防止每个销孔的内周表面和每个销孔的承载表面之间引起的局部磨损 销。
