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 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.

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： 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： 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： 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： 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： In a silent chain comprising interleaved and relatively pivotable rows of link plates, protrusions formed in the link plates contact relatively pivotable link plates in adjacent rows so that the area of contact is reduced. The protrusions can be annular, or they can be in the form of arcs that are of a size and position such that the arcuate protrusions of each plate do not interfere with the arcuate protrusions of an adjacent plate as the chain bends during use. The plates can have rectangular protrusions, or arcuate protrusions each consisting of an arc-shaped collection of dot-shaped protrusions.
