63 METHOD FOR MACHINING TOOTH EDGES AND MACHINING STATION DESIGNED FOR THIS PURPOSE US14907576 2014-07-15 US20160158861A1 2016-06-09 Kurt Kleinbach; Juergen Kreschel; Matthias Philippin; Edgar Weppelmann
The invention concerns a method for the machining of the tooth edges between an axially facing surface and the tooth flanks of a gear with a machining tool that has a toothed contour. For the material-removing cutting operation, the machining tool, rotating about the axis of its toothed contour, is brought into rolling engagement with the toothed workpiece under a crossing angle different from zero between the rotary axes of the machining tool and the toothed workpiece.
64 METHOD FOR DETERMINING THE FLANK FACE CONTOUR OF A GEAR SKIVING TOOL, GEAR SKIVING TOOL AND USE THEREOF US14440093 2013-11-07 US20150314382A1 2015-11-05 Marcel SOBCZYK
A clearance angle, of a blade-like tool or tool tooth of a tool for hob peeling workpieces is determined by defining the rake face contour of the tool and calculating the progression of path movement of the rake face during chip-breaking hob peeling, taking into account a pre-determinable transmission ratio between the tool and the workpiece determined by the respective number of teeth, and the desired tooth cross-section contour of the tool, and determining a tangential speed for points of the cutting edge of the tool during chip-breaking, wherein hob peeling is determined in the form of vectors that are displayed graphically as bundles for each point on the cutting-edge and a closed envelope surface is determined, which plus a desired clearance angle is selected as the shape for the flank face contour of the tool or of the flank face of the tool tooth. A tool is also provided.

A polishing fleece (33) which can be introduced into at least one tooth gap (39) of a gear (30) that is to be polished is mounted on the base (32). At least some sections of the polishing fleece (33) have an external contour that is adapted to the shape of a tooth flank (37). The tooth flank polishing tool can be used for polishing gears (30) or threads.
68 Method for Cutting Worm and Worm Wheel in a Worm-Gear Reduction Unit with Circulation of Bearing Balls, and Related Cutting Tools US10592977 2005-03-14 US20080273935A1 2008-11-06 Pietro Salvini; Domenico Serpella; Francesco Vivio; Vincenzo Vullo
A method for cutting worm and worm wheel in a worm-gear reduction unit (1) with circulation of bearing balls, comprising the steps of: (a) obtaining races (30) for the bearing balls (4) onto the worm wheel (3); and (b) obtaining races (20) for the bearing balls (4) onto the worm (2), wherein step (b) provides the cutting of the races (20) according to a cutting profile substantially corresponding to the envelope of the subsequent positions assumed by the bearing balls within the worm wheel races being formed.
69 Gear tooth profile US10420141 2003-04-22 US06964210B2 2005-11-15 John R. Colbourne
A gear and method for producing the gear. The gear has a gear tooth profile conjugate to a gear basic-cutter tooth-profile having an addendum with a convex portion having an addendum point proximal to a pitch line and a dedendum with a concave portion having a dedendum point proximal to the pitch line. The convex portion is complementary with a corresponding portion of a mating-gear basic-cutter tooth-profile dedendum. The concave portion is complementary with a corresponding portion of the mating-gear basic-cutter tooth-profile addendum. A transition zone between the addendum point and the dedendum point has a predetermined width. The gear basic-cutter tooth-profile has a predetermined half pitch relief at the pitch line and continuity of profile and continuity of slope at the addendum point.

71 Method for producing a two-part member having rack teeth US500897 1996-07-02 US5718544A 1998-02-17 Koichiro Nakatani
A base member such as an elevation pipe of a photographic tripod is severed and rack teeth are formed thereon in a single operation while the base member remains clamped in a V-block. The first rack tooth on each side of the location where the base member is severed includes half of a trough portion between adjacent rack teeth. Additional trough portions forming the remainder of the teeth are formed, either in the same severing and shaping operation, or in a later shaping operation. The formation of the inner half trough portions ensures that, when the two severed ends of the base member are brought together, a smooth transition will exist between the two rack portions. In addition, since the two severed ends always include half troughs immediately adjacent thereto, weaknesses and chipping resulting from the presence of partial rack teeth in these locations is avoided.
72 Method for cutting involute gears US347728 1989-05-05 US4971487A 1990-11-20 Shigeyoshi Nagata
A method for simultaneously cutting and chamfering involute gears. The pressure angle .alpha..sub.1 and module M of the teeth of a hob for cutting the teeth are selected with respect to the nominal pressure angle .alpha..sub.0 and nominal module m of the gear to be cut according to the following equation: m cos .alpha..sub.0 =M cos .alpha..sub.1. According to the present invention, a single hob cutter is sufficient to cut gears having a wide range of numbers of teeth.
73 Shaving cutter for finishing gears US437538 1974-01-28 US3960055A 1976-06-01 Joseph A. Psenka; Richard W. Tersch
A shaving cutter having a circular array of teeth of the same number and approximate size as that of a gear to be shaved, and having cutting edges at one end of the teeth of identical profile as that to be formed on the gear teeth, the teeth of the cutter being backed off to provide cutting clearance and dimensioned to be received simultaneously in all of the tooth spaces of the gear with circumferential clearance. Relative reciprocation is provided with timed relative circumferential depth feed to shave first one side and then the other of the gear teeth. The teeth are provided with cutting edges occupying different planes to avoid having all teeth initiate cutting action at the same time.
