摘要： The present invention improves accuracy in the axial dimension of rolled parts for a chain such as bushings, rollers and similar. A rolled part is manufactured by cutting a strip of steel into a rectangular shape to obtain a rectangular base material having a predetermined dimension, The rectangular base material is rolled into a clindrical shape to obtain a cylindrically formed part having cut end surfaces face each other. A core is inserted for rolling the rectangular base material into the cylindrically formed part. The cylindrically formed part is then pressed through a die having a circular opening. The rolled part has a plurality of blind grooves on a surface thereof. While the cylindrically formed part is being pressed through the die having a circular opening, a plastic flow of the material of the cylindrically formed part intensively occurs in a direction toward the blind grooves. Since the plastic deformation of the rolled part is absorbed by the blind grooves, axial dimension of the rolled part hardly varies,

摘要： A low-noise chain member comprises a bushing, a roller and oil grooves in which a wedge or squeeze effect of a lubricating oil, which is interposed between the bushing and the roller, is effective in reducing noise. The oil grooves are provided on at least one of the outer surface of the bushing and the inner face of the roller. The inner face of the roller is formed with a curved surface so as to conform to the contour of a curved outer surface of the bushing. A clearance between the inner face of the roller and the outer surface of the bushing is not widened around both ends of the roller. Only a small amount of the lubricating oil between the roller and the bushing escapes to the outside, of the roller and bushing, so that a fluid lubricating state between the bushing and the roller is maintained.
摘要翻译：一种低噪声链条构件包括衬套，辊和油槽，其中插入在衬套和辊之间的润滑油的楔形或挤压效应有效地降低了噪音。油槽设置在衬套的外表面和辊的内表面中的至少一个上。辊的内表面形成有弯曲表面，以符合衬套弯曲外表面的轮廓。辊的内表面与衬套的外表面之间的间隙不会在辊的两端加宽。辊和衬套之间只有少量的润滑油逸出到辊和衬套的外部，从而保持衬套和辊之间的流体润滑状态。

摘要： A barrel-shaped coil spring roller is formed by closely winding spring wire rods having fine crepe-like concave-convex surfaces on the surface of the barrel-shaped coil spring roller. The fine crepe-like concave-convex surfaces serve as a lubricating oil reservoir and are formed by a shotpeening process. Lubricating oil is retained on the fine crepe-like concave-convex surfaces formed by the shot-peening process. Sliding noises between the spring wire rods adjacent to each other, which noises are generated by elastic deformation of the barrel-like coil spring roller when in engagement with the toothed surface of the sprocket, are reduced by the lubricating oil. The wear on both of the barrel-shaped coil spring roller and the sprocket is lessened and the power loss is reduced. The low noise chain is capable of retaining a lubricating oil on the surface of spring wire rods of a barrel-shaped coil spring roller for long periods of time, while still maintaining a noise reduction effect.
摘要翻译：桶形螺旋弹簧辊通过在筒状螺旋弹簧辊的表面上紧密地卷绕具有细绉状凹凸表面的弹簧丝杆而形成。细绉状凹凸面用作润滑油储存器，并通过喷丸处理形成。润滑油保持在通过喷丸处理形成的细绉状凹凸表面上。通过润滑油减少了与链轮的齿形表面接合时，筒状螺旋弹簧辊的弹性变形产生的彼此相邻的弹簧线棒之间的滑动噪声。筒状螺旋弹簧辊和链轮两者的磨损减小，功率损耗降低。低噪声链条能够长时间保持桶形螺旋弹簧辊的弹簧线棒的表面上的润滑油，同时仍然保持降噪效果。

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.
摘要翻译：公开了一种用于链条的轧制产品和用于生产轧制产品的方法。多个凹坑在轧制品的内周面和外周面的至少一个中以锯齿形形成，当轧制产品被迫通过模具的圆形孔时，凹坑吸收轧制工件的塑性变形，并且多个凹部由在轧制产品的轴向上的凹凸表面上的任何假想直线上的凹坑限定。由凹坑吸收塑料流动防止在轧制产品的端面发生波动现象。当轧制产品用作诸如衬套或辊子的链条部件时，可以防止润滑剂在轧制产品的轴向上泄漏，并且因此可以改善旋转和滑动部分中的润滑剂保持性能。
