摘要： A rolled product for a chain and a method for producing the rolled product are disclosed. Plural dimples are formed in a zigzag pattern in at least one of inner and outer peripheral surfaces of the rolled product, the dimples absorbing plastic deformation of a rolled workpiece when the rolled product is forced through a circular orifice of a die, and plural recessed portions are defined by the dimples on any imaginary straight line on the dimpled surface in the axial direction of the rolled product. The absorption of plastic flow by the dimples prevents a waving phenomenon from occurring at the end faces of the rolled product. When the rolled product is used as a chain component such as bushing or roller, it is possible to prevent leakage of a lubricant in the axial direction of the rolled product, and hence possible to improve the lubricant retaining performance in a rotating and sliding portion.

摘要： A transmitting multi-row chain having easy disassembling or assembling such as dismounting or mounting a chain on its sprockets and, when even high load chain tension is applied, the high load is dispersed to each inner plate so that the load balance in the chain width direction is improved. A transmitting multi-row chain in which inner link units each comprising inner plates into which bushes are press-fitted are coupled in parallel with each other through intermediate plates in a width direction of the chain. The coupled inner link units are connected to each other in a large number by connecting pins having a diameter smaller than the diameters of the pin holes of the intermediate plate. The connecting pin is inserted into the pin hole 121 of the intermediate plate whose pitch between pin holes is narrower than the pitch between pin holes of the outer plate, the pin having a medial bend directed toward the pitch zone of the outer link in a state where chain tension is not generated. The bend extends substantially the full width between the outer and intermediate plates when chain tension is generated.

摘要： A transmitting multi-row chain in which the chain strength is high, the chain is lightweight, and the disassembly and assembly operation of the chain such as disconnecting and connecting of the chain and the like is simple. A transmitting multi-row chain has inner link units, each comprising a pair of right and left inner plates into which a pair of front and rear bushes is press-fitted. The inner link units are connected in rows to each other in large numbers in the longitudinal direction of the chain by connecting pins and the rows are disposed in parallel with each other through intermediate plates in a width direction of the chain. The connecting pins are press-fitted into outer plates disposed on the outermost sides in the width direction of the chain and are loosely fitted into pin holes of the intermediate plates. The intermediate plates are each formed in a plate height dimension smaller than the plate height dimension of each of the inner plate and the outer plate. The ends of the intermediate links are semi-circular with a bulge in the plate-shearing direction.
