1	LAMINATED GEAR SHAVING TOOLS	EP86904241.0	1986-06-18	EP0228436A1	1987-07-15	CROCKETT, James Cecil
Un outil laminé destiné à l'ébarbage d'une roue dentée est formé par un empilement de disques, dont deux (60, 61) sont représentés en plan développé, montés sur un corps rotatif. Les flancs de chaque dent (62a-62h) sont crénelés pour former des plats (70, 80), ces plats étant successivement décalés latéralement sur l'épaisseur du disque autour de la circonférence, pe une arête de coupe (76) des plats (70) se déplace de la position (70a) à (70h). Les arêtes de coupe (70, 76, 82, 84) peuvent être inclinées sur toute l'épaisseur des dents et/ou les faces latérales (68, 74, 78, 86) peuvent être rentrantes; les disques (60, 61) peuvent être inclinés par rapport à l'acte de rotation de l'outil; là où les plats correspondants (70, 80) ne sont pas décalés, des disques dentés peuvent être séparés par des disques d'espacement.

1,032,963. Gear-finishing. CARL HURTH MASCHINEN - UND - ZAHNRADFABRIK. Dec. 10, 1962 [Feb. 8, 1962], No. 26535/62. Heading B3K. A method of shaving a gear comprises using a tool having cutting edges which are so staggered and arranged that during a number of revolutions all parts of the gear tooth flanks will co-operate an equal number of times with the associated cutting edges, each chip 29, Fig. 5, being removed so that its thickness increases from the previously machined to the unmachined portion of the tooth flank. The chip formation is obtained by a correct choice of the relationship between the crossed axis setting 24, Fig. 2, the helical direction of the offset l of the cutting edges and the direction of rotation 25 of the tool. No traverse, or only slight traverse, is used. Specification 1,032,910 describes a related operation.

Gear cutting tool. There is provided a toothed tool for the plunge cut shaving of a gear workpiece having in the tooth surfaces a plurality of grooves whose edges constitute cutting edges, which grooves are spaced apart to define increments on each tool tooth equal to the number of teeth of the workpiece or one whole multiple thereof, and wherein when the tool is in a crossed axes relationship with the workpiece axis said cutting edges of those tool teeth spaced circumferentially a number of teeth equal to the number of teeth on the workpiece, or an integral multiple thereof, define a helix whose portion diametrically opposite the common perpendicular between said axes when viewed along said axis toward said workpiece forms an angle with the workpiece axis which is smaller than the complement of the angle between the tool axis and the workpiece axis. Thus, when said tool axis is rotated with respect to said workpiece axis in a clockwise direction, said cutting edges form a lefthand helix and when said tool axis is rotated with respect to said workpiece axis in a counterclockwise direction, said cutting edges define a righthand helix.

A gear or rack-shaped tool is provided with serrated teeth wherein the serrations extend from the addendum to the dedendum of the teeth in any given tooth surface. The serrations define ribs which are of such width and so arranged that throughout the effective width of the tool the ribs in any plane normal to the tool axis and taken around the full circumference thereof will total an area equal to the corresponding area of the ribs in any other such plane. In the illustrated embodiments this is accomplished by providing ribs and grooves which are arranged on circumferentially successive teeth in a manner axially offset with respect to one another and wherein (a) said offsetting is such that the edges of ribs on circumferentially spaced teeth are at least substantially coplanar with respect to each other, (b) the magnitude of such offsetting is a sub-multiple of the combined width of a serration and a rib, preferably, (c) said offsetting is of a magnitude which is a sub-multiple of the axial dimension of said ribs. Further, all of said ribs in such embodiments are of equal dimension in an axial direction with respect to each other, all of said serrations are of equal dimensions in an axial direction with respect to each other, and the serrations themselves are of a dimension in axial direction which is equal to the corresponding dimension of the ribs. In one illustrated embodiment, the edges of adjacent ribs on successive teeth form a helical curve circumferentially around a tool whereas in the other illustrated embodiment ribs which are on teeth circumferentially spaced by two or more tooth positions are helically aligned and the corresponding ribs on intervening teeth define similar axially spaced helical lines. Of course, where the tool is a rack instead of a gear, then the lines above referred to as helical become angling lines across the width of the rack. Thus, the several ribs will bear upon each element of each workpiece tooth an equal number of times and, insofar as possible within the tolerances at which the workpiece is machined without either gap or overlapping.
7	Gearlike tool with helically arranged grooves	US3685112D	1971-02-18	US3685112A	1972-08-22	LOHRER JOSEF
A gearlike tool adapted for working a gear by rolling. The tooth surfaces of said tool are provided with grooves for forming cutting edges. Said grooves are offset axially along a section of a helix, which section when axially measured comprises a groove pitch or multiple thereof plus or minus a selected amount and is equal to the amount of groove offset from one tooth to the next of the workpiece multiplied by the number of such teeth. Further, said length is of a value other than that of the selected amount and the entire number of teeth of the tool is an integral multiple of the groove pitch divided by the groove offsets from one tooth to the next.

9	Laminated gear shaving tools	US14045	1987-02-17	US4848976A	1989-07-18	James C. Crockett
A laminated gear shaving tool formed by a stack of toothed discs mounted on a rotatable body. The flanks of each tooth are cut away to form lands, the lands being successively laterally displaced (staggered) across the disc thickness around the circumference. The cutting edges may be inclined across the tooth thickness and/or the lateral face may be re-entrant; the discs may be inclined to the axis of rotation of the tool; and, where the corresponding lands are not staggered, the toothed discs may be separated by spacing discs.
