摘要： Link plates connected together by connecting members to form an endless silent chain each include a pair of teeth and a pair of connecting holes each receiving therein one of the connecting members. The teeth each have an outer flank, an arcuate tip end portion, and an inner flank. The outer flank has a rectilinear tooth face having an intermeshing point, and a tooth length extending from the intermeshing point toward a tip end of each tooth. The tooth length is 5 to 15% of a pitch between the connecting members. The tip end portion has a first arc adjacent to the outer flank and a second arc adjacent to the inner flank, the second arc having a smaller radius of curvature than the first arc. The shortest distance from a junction between the first and second arcs of the arcuate tip end portion to a face angle forming line of the outer flank is 0.5 to 3.0% of the pitch between the connecting members. With this construction, the silent chain can decrease a collision speed with respect to the tooth face of a sprocket at the time of intermeshing to thereby reduce noises, and provide a smooth and positive intermeshing with the sprocket.
摘要翻译：通过连接构件连接在一起以形成无声无声链的连接板各自包括一对齿和一对连接孔，每个连接孔在其中容纳连接构件中的一个。齿各自具有外侧面，弓形末端部分和内侧面。外侧面具有具有相互啮合点的直线齿面和从啮合点朝向每个齿的末端延伸的齿长。齿长为连接部件间距的5〜15％。前端部分具有邻近外侧面的第一弧形部分和与内侧面相邻的第二弧形部分，第二弧形部分具有比第一弧形部分更小的曲率半径。从弓形末端部的第一弧和第二弧之间的接合处到外侧面的面角成形线的最短距离为连接部件之间的间距的0.5〜3.0％。利用这种结构，无缝链可以减少啮合时相对于链轮齿面的碰撞速度，从而减少噪音，并提供与链轮的平滑和积极的啮合。

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 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： 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.

摘要： A silent chain include a number of link modules articulately connected together in an endless fashion by rocker joint pins. The rocker joint pins include a first rocker joint pin composed of a first longer pin and a first shorter pin each having a different first thickness in a direction of pitch of the rocker joint pins, and a second rocker joint composed of a second longer pin and a second shorter pin each having a different second thickness in the direction of pitch of the rocker joint pins. The second thickness of the second longer or shorter pin is different from the first thickness of a corresponding one of the first longer and shorter pins. The first joint rocker pin and the second rocker joint pin are arranged in a random pattern along the length of the silent chain so as to suppress generation of periodic noise when teeth of the silent chain and teeth of a sprocket engage with each other.

摘要： Two rocker pins inserted into each of two pin holes of each link plate of a silent chain each include a rocker surface, a first non-contact surface opposed to an inner peripheral surface of the pin hole on a side opposite to the rocker surface, a pair of load-bearing surfaces contiguous with both circumferential ends of the first non-contact surface, and two second non-contact surfaces interconnecting the pair of load-bearing surfaces and both circumferential ends of the rocker surface, respectively. A part of the inner peripheral surface of the pin hole is formed in a pair of pin-seating surfaces which is in register with the pair of load-bearing surfaces of each rocker pin, respectively, to prevent rotation of the rocker pin within the pin hole. Since the load-bearing surfaces are supported by the pin-seating surfaces in an exactly matched or registered condition, rotation and wobbling of the rocker pin within the pin hole are securely prevented. Thus, the rocker pins and the link plates are substantially free from local wear which may often result in an excessive wear elongation of the silent chain.
摘要翻译：插入无声链的每个连接板的两个销孔中的每一个的两个摇杆均包括摇杆表面，与摇杆表面相对的一侧的销孔的内周表面相对的第一非接触表面，一对与第一非接触表面的两个周向端部邻接的承载表面和两个第二非接触表面，分别将一对承载表面和摇臂表面的两个周向端部互连。销孔的内周面的一部分形成有一对销座，其分别与每个摇杆的一对承载表面对准，以防止摇杆在销的内部旋转孔。由于承载表面以精确匹配或注册状态的销座表面支撑，所以可靠地防止了销孔内的摇杆的旋转和摆动。因此，摇臂销和连接板基本上没有局部磨损，这常常导致无声链的过度的磨损延伸。

摘要： A silent chain power transmitting device includes a driving sprocket and at least one drive sprocket, and a silent chain stretched over the driving and driven sprockets to provide a tension run and a slack run on opposite sides of the driving sprocket. The driving and driven sprockets have a sprocket pitch (chordal pitch) designed to become substantially equal to a chain pitch of the tension run of the silent chain while operating under load. By thus designing the sprocket pitch relative to the chain pitch, toothed link plates of the silent chain are smoothly guided into sliding contact with teeth of the sprockets without causing objectionable interference or collision. The sprockets and silent chain are substantially free from abnormal wear and hence have an increased degree of durability.

摘要： A silent chain includes double rocker joint pins articulately connecting together adjacent links of the chain. The double rocker joint pins are each composed of a longer pin and a shorter pin. The longer pin has a cross-sectional shape different from that of the shorter pin, and the thickness of the longer pin as measured in a direction parallel to a chain pitch line is made greater than the corresponding thickness of the shorter pin. By thus designing the longer pin relative to the shorter pin, the longer pin has a large mechanical strength sufficient to withstand not only an impact force applied when the longer pin is swaged or riveted at opposite ends thereof, but also a shear force and a bending force applied at one time to opposite end portions of the longer pin during power-transmitting operation of the chain.

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 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.
