Die Erfindung betrifft ein Verfahren zum Herstellen der Verzahnung eines Zahnrades, die ein Modul aufweist, der kleiner als 0,5 mm ist oder der kleiner als 0,25 mm ist oder der kleiner als 0,15 mm ist, und die x Zähne und eine Zahnradteilung p aufweist, wobei von einem Zahnradrohling, der um eine erste Rotationsachse rotiert, Material mittels eines Werkzeugzahnrades abgetragen wird, das synchron zu dem Zahnradrohling um eine zweite Rotationsachse rotiert und das eine zur herzustellenden Verzahnung komplementäre Gegenverzahnung aufweist. Das Verfahren zeichnet sich dadurch aus, dass benachbarte Zähne der Gegenverzahnung auf dem Teilkreis jeweils um n·p (n multipliziert mit p) voneinander beabstandet sind, wobei n eine natürliche Zahl größer 1 ist und wobei x und n teilerfremd sind. Insbesondere kann vorteilhaft vorgesehen sein, dass das Abtragen mittels Wälzschälen oder Wälzschälschleifen erfolgt, wobei der Vorschub des Werkzeugs in Richtung der ersten Rotationsachse im Vergleich zu einem herkömmlichen Wälzschälprozess oder Wälzschälschleifprozess um den Faktor n reduziert ist.

| The invention relates to a method for providing teeth on working gears by means of a cutting tool (2) having cutting teeth (3), wherein the working gear and the cutting tool (2) are driven in rotation at a predetermined speed ratio to one another, a workpiece spindle axis and a tool spindle axis are oriented at an axis intersection angle to one another. The tooth flanks (6, 6') of the cutting teeth (3) form, on the front ends thereof, cutting edges having flank cutting sections which are arranged on the edges of a gap (20) between two adjacent cutting teeth (3) and extend along a first contour line, and which as a result of an advance in the direction of the toothing of the working gear engage in the working gear in a cutting manner to produce teeth having a tooth flank contour predetermined by the shape of the cutting edge. According to the invention each of the two flank cutting sections is adjoined by a tip cutting section which extends along a second contour line in the region of the base of the cutting tooth gap (20), wherein the second contour line is curved having a foot corner curvature, and at least partially rounded tooth tips are produced on the teeth by the tip cutting sections. Thus teeth having rounded tips can be produced. | ||||||

Jeder Zahn eines Schrägschneidrades hat eine Zahnkopffläche (16) und eine tiefe Flanke (18) sowie eine hohe Flanke (20). Über die Lebensdauer des Schrägschneidrades müssen diese Flanken immer wieder nachgeschärft werden. Infolge des Nachschärfens in Form eines Treppenscharfschliffes treten dabei üblicherweise Treppenschliffehler auf. Mit Hilfe spezieller Korrekturmethoden läßt sich der Einfluß dieser Treppenschliffehler wesentlich mindern. In der oberen Darstellung ist das unkorrigierte, genaue Evolventenprofil der tiefen Zahnflanke (18) und der hohen Zahnflanke (20) jeweils mit dicken Linien dargestellt, und zwar in der oberen Figur für einen ersten Stirnschnitt und in der unteren Figur für einen zweiten Stirnschnitt. Zwischen diesen beiden Stirnschnitten liegt eine sogenannte Abnützungsphase. Mit dünnen Linien sind schematisch und unmaßstäblich die zugehörigen Korrekturen dargestellt, welche die Flankenprofile in den betreffenden Stirnschnitten aufweisen müssen, damit sich die erwünschte Korrektur des Treppenschliffehlers ergibt. |

| A controller of a gear cutter machining apparatus includes a rotation control unit and a movement control unit. The rotation control unit rotates a gear cutter about a central axis of the gear cutter, and rotates a grinding wheel about a central axis of the grinding wheel. The movement control unit gradually changes a crossed axes angle when relatively moving the grinding wheel in a direction of the central axis of the gear cutter, and moves the grinding wheel in a translating direction that is a rotational tangent direction of the gear cutter. | ||||||

| A gear shaper or shaver cutter which has broken or damaged teeth is salvaged by removing good teeth from an identical cutter which is otherwise unsalvagable. The removal of damaged teeth from the salvagable cutter, and removal of good teeth from the unsalvagable cutter, is done by electrical discharge machining (EDM) wire. The good teeth are removed as an integral group which is snugly fitted into and plugs the slot where the damaged teeth were removed from the salvageable cutter. The group is locked in place by a lock pin in an aperture made by EDM electrode procedure, the lock pin being welded in place by electron beam welding, and or any other suitable state of the art. | ||||||

| A spline cutting mechanism according to the present invention comprises a generally frusto-conical cutter having a cutting edge and a trailing edge. A plurality of teeth are defined in the periphery of the cutter at the cutting edge, each having a clearance at the cutting edge and behind the cutting edge. The cutter is supported by a cutter shaft that is freely supported for sympathetic rotation in a cutter housing by a plurality of bearings. The cutter housing is adapted for mounting on a conventional compound slide of a lathe in such manner as to dispose the axis of the cutter in angular relation with work that is rotatably supported by a lathe chuck. The freely rotatable cutter is advanced into the rotating work by the lead screw of the lathe to cut either external or internal longitudinal splines into the work.

| Method of manufacturing teeth, notably of gearings having their outline cut integrally by means of a pinion-tool, wherein an apparent outline of theoretical pinion-tool for different states of wear of said tool is calculated from the outline of the desired workpieces and of its generating rack ; from the surfaces of the teeth of the theoretical pinion-tool a theoretical hob is calculated for generating said surfaces ; a simplified hob is then made from said theoretical hob, and used for milling piniontools adapted to produce rough-cut gears after sharpening the leading faces of said pinion-tools ; the outlines of these gears are then compared with the desired outline for any possible correction of the simplified hob outline and the resultant correction of the pinion-tools and workpieces ; this method is applicable to the cutting of spur or helical teeth, whether of the involute type or not, for both internally toothed and externally toothed gears, by using milled pinion-tools.
