Title
(EN) CYLINDRICAL SHAFT AND METHOD OF MANUFACTURING THE SAME
(FR) ARBRE CYLINDRIQUE ET PROCEDE POUR SA FABRICATION
(JA) 円筒軸とその製造方法
Abstract
(EN)
A cylindrical shaft formed of a bent sheet metal (10) and a method of manufacturing the cylindrical shaft. The cylindrical shaft (20) comprises projected parts (16) projected from one end part (12) of the pair of joined end parts (12) and (14) of the sheet metal (10) and having portions which increase in width apart from the one end part (12) and recessed parts (18) formed in the other end part (14) of the pair of joined end parts, having such a shape that supplementarily matches that of the projected parts (16), and fitted to the projected parts (16). Thus, the cylindrical shaft high in roundness, less in both vertical and lateral warpages, and excellent in linearity can be provided.
(FR)
Arbre cylindrique formée d'une tôle métallique cintrée (10) et procédé pour la fabrication de l'arbre cylindrique. L'arbre cylindrique (20) comporte des protubérances (16) faisant saillie d'une partie terminale (12) de la paire de parties terminales jointes (12) et (14) de la tôle métallique (10) et présentant des portions dont la largeur augmente en s'éloignant de ladite une partie terminale (12), et des parties en creux (18) formées dans l'autre partie terminale (14) de la paire de parties terminales jointes, dotées d'une forme qui corresponde de manière complémentaire à celle des protubérances (16), et ajustées aux protubérances (16). Ainsi, un arbre cylindrique de bonne circularité, peu susceptible de gauchissement tant vertical que latéral, et d'une excellente linéarité peut être obtenu.
