Patent number: 9782847Abstract: A gear machining device is provided which can machine an accurate gear by a cutting process by synchronously rotating a machining tool and a workpiece at a high speed. A machining tool includes roughing cutting teeth for roughing bottom lands and right and left side faces of teeth of a gear, right side face finishing cutting teeth for finishing the right side faces of the teeth, and left side face finishing cutting teeth for finishing the left side faces of the teeth. The cutting teeth thus cut different parts of the teeth of the gear. This can reduce cutting resistance and suppress self-vibration during the cutting process, thereby improving tooth trace accuracy of the gear.Type: GrantFiled: April 28, 2015Date of Patent: October 10, 2017Assignee: JTEKT CORPORATIONInventors: Hisashi Otani, Hiroyuki Nakano, Hideki Shibata

Patent number: 9700981Abstract: The invention concerns a method for the chip-removing generation or machining of internal gear teeth on a workpiece which is rotatable about its rotary axis and radially delimits a free space that extends axially to one side beyond the internally toothed region and whose radial width narrows in the direction of its axial extension in at least one location. An externally toothed tool which is driven in rotary movement about its axis of rotation is brought from the opposite side into rolling engagement with the internally toothed region with the rotary axes crossed at an angle. Through the application of a mechanical force, the chips which are produced in the process and which are subject to a centrifugal force are caused to change their movement in the zone of narrowing width in a manner directed against the origin of the centrifugal force.Type: GrantFiled: January 27, 2014Date of Patent: July 11, 2017Assignee: GLEASON-PFAUTER MASCHINENFABRIK GMBHInventors: Johannes Brogni, Domenico Petrallia, Oswald Witschi
