、ピストンの短小化が要求されている。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention primarily relates to a method for plating a rail ring of a combination oil control ring made of steel for a small internal combustion engine. [Prior Art] Small internal combustion engines, such as four-stroke gasoline engines such as automobile engines, are aimed at higher output, smaller size and lighter weight, and are required to have shorter and smaller pistons.
従ってピストンの構成部品であるピストンリングの上下
幅寸法も縮小を余儀なくされている。また、高回転、高
出力化を指向するピストンリングの慣性力低減策として
も幅寸法の縮小化は強く望まれている。Therefore, the vertical width dimension of the piston ring, which is a component of the piston, has also been forced to be reduced. Furthermore, reducing the width dimension is strongly desired as a measure to reduce the inertia of piston rings aimed at high rotation and high output.

っている。Examples of reductions in ring width include compression rings from 1.2 mm to 1.2 mm; It has been reduced to Om. Also, the oil control ring has gone from 4 holes to 2.5mm, and even 2 sections.
これらの寸法縮小は、リングの機能面及び製造面にいく

の必須条件でもある。These size reductions leave some challenges in terms of ring functionality and manufacturing, particularly in the case of prepared combination oil rings, the extremely thin rail ring width dimension is also a prerequisite for size reduction.

不可能になるめっき渡り現象が発生することがある。In the manufacturing process in which wear-resistant chrome plating is applied to the outer or inner circumference of rail rings, plating is continuously deposited between adjacent rings in the gaps where plating is performed with multiple rail rings stacked. A plating phenomenon may occur that makes it impossible to separate the rings individually.

より解決した。An object of the present invention is to solve the above-mentioned conventional problems and provide a plating method that does not cause the plating build-up phenomenon even when a sufficient thickness of wear-resistant plating is applied to a rail ring with a small vertical width dimension. [Means for Solving the Problem] The present invention solves the above problem in a method for plating a rail ring of a steel combination oil control ring having a wear-resistant plating layer on at least one of the outer periphery and the inner periphery. ,
A shape similar to that of the rail ring, having a dimension that satisfies at least one of a diameter that is somewhat smaller than the outer diameter of the rail ring or a diameter that is somewhat larger than the inner diameter between the individual rail rings that are stacked multiple times. The problem was solved by a rail ring plating method characterized by arranging an intermediate ring and performing the plating process.

めっき付着部分が中間リングによって離反されることに
なり、めっき渡りを生しない、また、輻消の中間リング
を使用すると隣接するレールリング間の距離間隔が極狭
となるため中間リング表面にめっきは付着されない。According to the present invention, a large number of rail rings to be plated are stacked with an intermediate ring interposed between them, and in this case, the outer diameter of the intermediate ring is smaller than the outer diameter of the rail ring, or the inner diameter of the intermediate ring is smaller than that of the rail ring. Since either the inner diameter is larger than the inner diameter, or both are satisfied, the intermediate ring portion is concave at one or both of the outer circumferential portion and the inner circumferential portion between the rail rings. Since it is plated in this state,
The part to which the plating is attached will be separated by the intermediate ring, and no plating will occur. Also, if a radiation-dissipating intermediate ring is used, the distance between adjacent rail rings will be extremely narrow, so the plating will not be applied to the surface of the intermediate ring. Not attached.
