Title (EN) METHOD FOR MANUFACTURING RIBBON CAGE AND RIBBON CAGE
(FR) PROCÉDÉ DE FABRICATION D'UNE CAGE À RUBAN ET CAGE À RUBAN
(JA) 波形保持器の製造方法及び波形保持器
Abstract:
(EN) In the process of manufacturing a ribbon cage, an intermediate assembly (17a) is configured by press-fitting press-fit portions (24, 24) provided at base ends of pestle portions (13b, 13b) of respective rivets (9b, 9b) into respective through-holes (12a, 12a) of one cage element (8a), and the intermediate assembly (17a) is subjected to nitriding treatment. The axial dimension (X) of each of the press-fit portions (24, 24) is set smaller (X
(FR) L'invention concerne un procédé de fabrication d'une cage à ruban, caractérisé en ce qu'un ensemble intermédiaire (17a) est conçu par des parties à ajustement serré d'ajustement serré (24, 24) ménagées au niveau d'extrémités de base de parties de pilon (13b, 13b) de rivets respectifs (9b, 9b) dans des orifices traversants respectifs (12a, 12a) d'un élément de cage (8a), et l'ensemble intermédiaire (17a) est soumis à un traitement de nitruration. La dimension axiale (X) de chacune des parties à ajustement serré (24, 24) est définie plus petite (X
(JA)  波形保持器の製造過程で、一方の保持器素子8aの各貫通孔12a、12aに、各リベット9b、9bの杆部13b、13bの基端部に設けた圧入部24、24を圧入する事により、中間組立体17aを構成し、中間組立体17aに対して窒化処理を施す。各圧入部24、24の軸方向寸法Xは、各貫通孔12a、12aの軸方向寸法Yよりも小さく(X<Y)する。これにより、各貫通孔12a、12aの内周面と各杆部13b、13bの外周面との軸方向一部分に、互いに密接しない部分を設け、これら各密接しない部分に窒化層が形成される様にする。
