Abstract

PURPOSE: To remove boundary layers of organization between a cylindrical side wall and gear teeth portions and improve strength thereof by forming the gear teeth portions on a cylindrical drum by means of forging utilizing a pair of dies applied from the inner and outer surfaces of the cylindrical wall.
CONSTITUTION: Teeth portions 8 having channel type cross-sections are formed radially on a cylindrical portion 7 of a cylindrical drum type frame 2 used for cluth- outer and the like. Side walls 10, 11 of the tooth portion 8 are formed so that θ1 that means an angle between the inner surfaces 10a, 11a and directions of radii thereof is bigger than θ2 that means an angle between the outer surfaces 10b, 11b and directions of radii thereof and that the thickness of the side walls 10, 11 is increased as the length of radius thereof is increased. Radius of curvatures r1, r2 for the inner surfaces 12a, 12b of the top portion 12 for the teeth are kept in a relation of r1<r2. For the formation of the teeth portions 8, a pair of dies are utilized and a panch 20 is set at an inner side while a die 21 is applied at an outer side respectively of the work W formed to have a shape of a cylindrical drum, thereafter, a press member 23 is descended to expand a tooth portion W1 outwardly, and thus, the teeth portions are formed by forging. Consequently, boundary layers are not produced between the sylindrical side wall and the top portions of the teeth, and thereby, the strength of the teeth portions may be improved.
