Title:
トルクコンバータのブレード構造及びトルクコンバータのブレード構造の製造方法
Document Type and Number:
Japanese Patent JP4540693
Kind Code:
B2
Abstract:
A blade structure (11) for a torque converter that is produced according to a process which comprises stamping a flat sheet into a shape including a holding section (22,23), an inner connecting section (16) located around the holding section and held by the holding section (22,23), an outer connecting section (14) located around the inner connecting section, a plurality of blades (12) connected between the inner connecting section and the outer connecting section (14), and a plurality of core elements (30) projecting from respective ones of the blades (12). Said process further comprises angling the core elements by a first predetermined angle with respect to respective ones of the blades then bending the blades into a curved shape between the inner connecting section and the outer connecting section, angling the blades by a second predetermined angle with respect to the inner connecting section and the outer connecting section, displacing the holding section with respect to the inner connecting section perpendicularly of the sheet so as to shrink the sheet toward the holding section and shrink spaces between the blades and connect the core elements to respective two adjacent ones of the core elements. Then, the displaced holding section is removed from the sheet.
