スパンダとの間で相互に円周方向に滑りを生じエンジン
の潤滑油消費量を多くするという弊害が起きる。The inner peripheral surface of the side rail of a conventional combination oil ring is manufactured to be smooth. By forming the inner circumferential surface smoothly, the inner circumferential surface of the side rail slides smoothly in the axial direction on the contact surface with the inclined protrusion of the spacer expander.
The side rail can press against the side surface of the oil ring groove of the piston in which the side rail is disposed, thereby sealing the lubricating oil between the side rail and the side surface of the oil ring groove. However, depending on the engine operating conditions, side rails with such smooth inner surfaces may slip circumferentially between themselves and the spacer expander, increasing the amount of lubricating oil consumed by the engine. .

り解決した。The present invention solves the above problem in a method for manufacturing a side rail of a combination steel oil ring, in which a straight band-shaped wire is passed between a plurality of bins and curved into an annular shape.
A side rail of a combination steel oil ring characterized in that the side that will become the inner periphery of the side rail is pressed against at least one bottle having an uneven surface to form minute irregularities on the side that will become the inner periphery of the side rail. The problem was solved by the manufacturing method.

転造する。According to the present invention, a side rail is manufactured by passing a thin straight band-shaped wire rod, which is a raw material for a side rail, through a plurality of bins and forming it into an annular curve. The inner circumferential surface of the side rail that comes into contact with the side rail is pressed against one bottle, and the inner circumferential surface of the side rail is rolled with fine unevenness in the axial direction.
本発明の詳細を図に示す実施例に基づき説明する。 The details of the present invention will be explained based on embodiments shown in the drawings.

、円環状のサイドレール８を製造する。In FIG. 1, a thin straight band-shaped wire rod 1, which is the raw material for the side rail, is sent out from a supply section 2, sent by a pair of feeding bins 3.4, and passed between a plurality of bins, in the example shown in the figure. It is curved during the passage between the three bins 5.6.7, producing an annular side rail 8.

ル８の内周面に転写される。As shown in FIG. 2, groove-like unevenness 9 extending in the axial direction is formed on the surface of at least one pin, for example, the second pin 6, to which the inner circumferential surface of the annular side rail 8 is pressed. The wire 1 is connected to the annular side rail 8 by the third pin 7 in FIG.
When the second pin 6 is bent so as to have an uneven surface, the second pin 6 having the unevenness 9 on its surface comes into strong contact with the side of the wire rod 1 that becomes the inner circumferential surface of the side rail. It is transferred to the inner peripheral surface.

The unevenness 9' is formed.

By being pressed against this bin 61, the side rail 8
A V-shaped protrusion 12 is formed at the center of the inner circumferential surface. As a result, unevenness is formed on the inner circumferential surface of the side rail 8 at a position away from the apex, that is, at a position in contact with the protrusion of the spacer expander.
