Abstract (en)

[origin: US5619879A] PCT No. PCT/DE94/00209 Sec. 371 Date Dec. 28, 1995 Sec. 102(e) Date Dec. 28, 1995 PCT Filed Feb. 23, 1994 PCT Pub. No. WO94/20235 PCT Pub. Date Sep. 15, 1994This invention concerns a method and device for the non-cutting production of a hub (27) for a transmission component. A sheet blank (21) which is carried by a tool (3) on a main spindle (4) and rotated relative to one or more presser rollers (9, 10) is formed to produce a cylindrical prominence (7), projecting from the sheet by pressing it with a presser roller round a pin (5) mounted on the tool or a mobile stop (8) and passing through said sheet.
