In the recycling method, scrap of high-tensile steel plate and scrap of ordinary steel plate are collected together in a batch collecting process and, then, in a preparing process, the scrap steel plates collected are melted and if not less than 0.7 weight % manganese is contained in the hot metal, then the hot metal is prepared so that a sulfur content in the range of 0.02 to 0.2 weight % in the hot metal and rare earth element or misch metal which is two times as much as the sulfur content is added to the hot metal. To obtain spheroidal graphite cast iron, spheroidizing agent (which preferably comprises no rare-earth element but comprises bismuth) is added further to the hot metal after that.

摘要： In a sliding contact guide for a chain, a guide body is composed of a shoe having a front surface on which the chain slides, and a plate-receiving portion provided on the back of the shoe. The shoe and plate-receiving portion are integrally molded from a synthetic resin. A reinforcing plate is inserted and fitted into a longitudinal slot in the plate-receiving and the sliding contact guide is attached to a frame by a pivot pin which extends through aligned mounting holes in the guide body and the reinforcing plate. Locking pieces formed in the plate-receiving portion, have tapered surfaces on their tips that engage locking holes in the plate and exert a biasing force on edges of the locking holes which urges the plate against the back of the shoe. The reinforcing plate and the guide body are reliably secured together and, even when the guide is vibrated, movement of the reinforcing plate in the slot of the guide body is prevented, so that low noise and long life are attained.

摘要： A random arrangement type silent chain is provided, which restricts run-upon and reduces contact noise and vibration noise of the free span of the chain, and also restricts abnormal elongation and excessive load during power transmission. In the silent chain a first link plate, which begins to engage with a sprocket tooth by its inner crotch and sits on the sprocket teeth by its outer flanks, and a second link plate, which engages with and sits on the sprocket teeth only by engagement with its outer flanks, are mixed and combined in an endless chain in the longitudinal direction. The mixture ratio of the first link plates to the total link plates is less than 50%, at least one or more of the second link plates are arranged before and after each of the first link plates, and the number of second link plates arranged before and after each first link plate varies randomly along the length of the 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： 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 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.
