Title: Roll forming gear shaping tool with profile ledges
Inventor: LOOS HERBERT
IPC: B21H5/02
Filed: 1970-01-28
Abstract: The gear forming tool for use with gear rolling machines in which the work-piece is rolled against the tool, the axis of rotation of the two being parallel, is machined such that continuous ledges run along the tooth flanks from the crown to the root. The ledges are straight and run in planes at 90 degrees relative to the axis of the tool. They are also offset relative to each other on consecutive teeth. One ledge only i generated on the tool per tooth flank for machining the workpiece tooth flank. The provision of ledges greatly reduces the total working force active at a given time whilst increasing the specific working load per applied area.
