METHOD OF MANUFACTURING METAL RING FOR ENDLESS METAL BELT

Title:

METHOD OF MANUFACTURING METAL RING FOR ENDLESS METAL BELT

Document Type and Number:

WIPO Patent Application WO/2004/076094

Kind Code:

A1

Abstract:

A method of manufacturing a metal ring for endless metal belt capable of manufacturing the metal ring with less stress concentration and facilitating the manufacture and maintenance of a rolling roller transferring mesh-shaped irregularities on the metal ring. The mesh-shaped irregularities (8) are formed on the surface of the inner peripheral rolling roller (6). The irregularities (8) are formed by rotating the inner peripheral rolling roller (6) at a specified rotational speed, reciprocatingly moving a stone (9) in the axial direction of the inner peripheral rolling roller (6), and pressing the stone against the surface of the inner peripheral rolling roller (6) with a specified force. The number of the stone is set within the range of &num 270 to &num 1000. When the inner peripheral surface of the metal ring (1) is rolled by the inner peripheral rolling roller (6), the mesh-shaped irregularities (2) are transferred to the metal ring (1). Because the mesh-shaped irregularities (2) are formed by the transfer of the irregularities (8) formed by the stone (9), the widths thereof between the irregularities are small and random to provide excellent lubricity when the metal ring (1) is stuck. Also, the metal ring (1) with high compression residual stress and high toughness can be formed by applying solution treatment and nitriding to the metal ring (1).
