摘要： A sheet metal pulley has a base part and a cylindrical peripheral wall for winding a belt formed integrally with the base part. An ear is disposed in an end part of the cylindrical peripheral wall. The base part is partitioned into an inner peripheral portion and an outer peripheral portion, with the inner peripheral portion being smoothly connected with the outer peripheral portion through a bent part. The outer peripheral portion is formed into a tapered shape which extends from the bent part and has a diameter which is increased toward the inner side of the cylindrical peripheral wall in the axial direction of the pulley. The outer peripheral portion connected with an end part of the peripheral wall on the side of the ear. Even when the pulley is used for a long term, the connecting portion between the peripheral wall and the base part, etc. is hardly cracked.

摘要： The present invention relates to a sheet metal member having an annular peripheral wall and a method of thickening an annular peripheral wall of the sheet metal member. The thickness of the annular peripheral wall is increased to be 2 or more times or 3 or more times that of a base plate. Teeth for a timing toothed belt, a gear, or the like are cut in the annular peripheral wall which is thickened in this way. In the method of thickening an annular peripheral wall of the present invention, a base plate integrally having a flange-shaped portion is held between a circular bottom pattern tool and a circular top pattern tool, the flange-shaped portion which projects outwardly and the circular top pattern tool is sequentially pressed in a radially inward direction by annular forming faces of circular rollers of plural kinds, thereby thickening the flange-shaped portion. The flange-shaped portion is then formed into a cylindrical shape which is concentric with the base plate. According to the method, it is not required to separately produce the peripheral wall and the base plate and then weld them together. The peripheral wall can be provided with the strength required for cutting teeth in the peripheral wall.

摘要： The present invention relates to a method of producing a sheet metal pulley for a V belt without cutting which may impair the environment of a factory. A sheet metal pulley for a V belt which is obtained by the production method of the present invention has plural valley portions around which V belts are to be wound. In the production method, an annular first valley portion which is opened in a V-like shape is formed by slitting a root portion of a cylindrical portion of a sheet metal cylindrical member and an outer periphery of a base plate portion continuous to the root portion. A cylindrical portion continuous to the first valley portion is elongated in the axial direction while being thinned, thereby forming an intermediate shaped member, and, while applying a pressing force in the axial direction to the cylindrical portion of the intermediate shaped member, an intermediate portion in the axial direction of the cylindrical portion is pressed in a radial direction to be inwardly bent, thereby shaping the pressed place into an annular second valley portion. When the cylindrical portion of the sheet metal cylindrical member is sufficiently long, the elongation of the cylindrical portion is not required.
