Claims (1)
サイドレールの内周面を半径方向及び軸方向に押
圧するスペーサエキスパンダとからなる鋼製組合
せオイルリングにおいて、前記サイドレールの肉
厚を内周面から外周面に向けて漸次大きくし、か
つ前記窒化層はサイドレールの外周面にのみ形成
したことを特徴とする鋼製組合せオイルリング。 In a steel combination oil ring consisting of a side rail with a nitrided layer formed on the surface and a spacer expander that presses the inner circumferential surface of the side rail in the radial and axial directions, the wall thickness of the side rail is determined by the inner circumferential surface. 1. A steel combination oil ring, characterized in that the size of the oil ring gradually increases toward the outer circumferential surface of the side rail, and the nitrided layer is formed only on the outer circumferential surface of the side rail.
