Abstract

1280720 Rolling; forging gears GLEASON WORKS 6 Nov 1969 [17 Dec 1968] 54450/69 Headings B3H and B3M A tapered gear having spirally arranged teeth is formed by relatively moving a gear blank and a die together in the direction of the axis of the blank and also angularly about the axis. The die may be mounted in a forging press or in a rolling machine. In the forging press, a gear blank 8, Fig. 7, is supported on a stationary die part 33 and is approached by die member 19 mounted on an hydraulic ram 27. The ram is provided with helical splines 28 which cause it the ram and the die to rotate as they approach the blank. The die part 33 is hollow and is arranged to act as an ejector for the finished gear. For rolling a blank 18, Fig. 10, the blank is mounted on a plunger 53 and is moved axially towards an axially fixed but rotating die 50. As the die is fed towards the die it is rotatably indexed by the action of helical splines 57 cooperating with an axially fixed ring 58. The ring is driven rotationally and meshes with a holder 65 for the die 50 so that the die and blank rotate in unison.
