摘要： The invention relates to a method for machining toothed and hardened work wheels (1), comprising the following steps: mounting a work wheel (1) that is hardened and pre-toothed with an allowance onto a work piece spindle (4); removing at least 50% of the allowance by means of gear skiving with a skiving wheel (5) that is rotatably driven by a tool spindle (7); precision-machining the work wheel (1) in unchanged tension by means of a honing wheel (6). The forward movement (Vs) occurs during gear skiving in the extension direction of the toothing (2). The delivery (V
H ) of the work piece (1) that is moved in an oscillating manner in the extension direction of the toothing (2) occurs during honing in the radial direction. The skiving wheel (5) and the honing wheel (6) are driven by a common tool spindle (7). The invention also relates to a device for carrying out the method.-

摘要： The invention relates to a method and a device for gear cutting a work wheel (1) by means of gear skiving, wherein a first cutting wheel (2) sitting on a tool spindle (16) and having cutting teeth (11) is rotatably driven about a tool spindle axis (4), and the cutting teeth (11) engage in a machining manner into the work wheel (1) carried by a work piece spindle (15) and rotatably driven about a work piece axis (3) that is at an axis angle of intersection (α) to the tool spindle axis (4), in the event of a forward movement (V) in the extension direction of the teeth (5) of the toothing, wherein in a number of consecutive rough cuts, the tooth spaces (6) between left and right tooth flanks (7, 8) of the teeth (5) of the toothing are deepened via a change in the axial distance of the tool spindle axis (4) and the work piece spindle axis (3), and subsequently in finishing cuts, the left and right tooth flanks (7, 8) are precision machined. According to the invention, in order to improve the tooth flank quality, in a first finishing cut, only the left tooth flank (7) is machined with a chip removal point (14) moving from the top of the tooth (9) to the base of the tooth (10) with the gear skiving movement, and in a second finishing cut, only the right tooth flank (8) is machined with a chip removal point (14) moving from the top of the tooth (9) to the base of the tooth (10) with the gear skiving movement

摘要： The invention relates to a device for forming working gears (1) using a hob (10), wherein the working gear (1) can be driven rotationally by a workpiece spindle about a workpiece spindle axis (7), wherein the hob (10) can be driven rotationally by a tool spindle about a tool spindle axis (18) in a predetermined speed ratio relative to the working gear (1) and wherein the hob comprises cutting teeth (11, 21) whose cutting tooth bases (14, 24) run along a base line (15) in a longitudinal section through the hob (10) at the tool spindle axis (18), and whose cutting tooth heads (13, 23) run along a head line (16) in the longitudinal section, wherein advancing means are provided for moving the hob (10) relative to the working gear (1), wherein an axial component of the advancement runs in the direction of the workpiece spindle axis (7) and a radial component of the advancement runs substantially perpendicular to the axial component in the direction of the workpiece spindle axis (7). In order to form gears having tooth flanks with acute angles relative to one another, it is proposed that the head line (16) run at an acute angle (α) relative to the base line (15).

摘要： The invention relates to a gearwheel and to a method and device for producing gearwheels (6) that have undercut tooth flanks (7, 8). The workpiece is rotationally driven by a workpiece spindle, and a tool comprising a rotating fly cutter (4) is rotationally driven by a workpiece spindle (3) in a substantially fixed speed ratio to the workpiece spindle. The tool is displaced relative to the workpiece in the direction of the rotational axis (2) of the latter in such a manner that the fly cutter (4), with its cutting edge (10), lifts off one chip each along a first tooth flank (7) of a tooth (9) to be produced with every rotation. The second tooth flank (8) to be produced of said tooth extends at least in some sections at an acute angle to at least one section of the first tooth flank (7). The aim of the invention is to improve the aforementioned method and device in terms of its cost effectiveness and to provide a synchromesh gearwheel having improved stability. For this purpose, the second tooth flank (8) of every tooth (9) is produced independently of the first tooth flank (7). During production of the two tooth flanks (7, 8), the phase position of the rotational movement of the workpiece spindle (3) to the rotational movement of the workpiece spindle is varied during advance (c).

摘要： Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Verzahnen eines Werkrades (1) durch Wälzschälen, wobei ein an einer Werkzeugspindel (16) sitzendes, Schneidzähne (11) aufweisendes erstes Schneidrad (2), um eine Werkzeugspindelachse (4) drehangetrieben wird, und die Schneidzähne (11) in das von einer Werkstückspindel (15) getragene, um eine in einem Achskreuzwinkel (a) zur Werkzeugspindelachse (4) stehende Werkstückachse (3) drehangetriebenes Werkrad (1) bei einem Vorschub (V) in Erstreckungsrichtung der Zähne (5) der Verzahnung spanabhebend eingreifen, wobei in mehreren aufeinanderfolgenden Schruppschnitten die Zahnlücken (6) zwischen linken und rechten Zahnflanken (7, 8) der Zähne (5) der Verzahnung durch eine Änderung des Achsabstandes von Werkzeugspindelachse (4) und Werkstückspindelachse (3) vertieft werden, und darauf folgend in Schlichtschnitten die linken und rechten Zahnflanken (7, 8) feinbearbeitet werden. Zur Verbesserung der Zahnflankenqualität wird vorgeschlagen, dass in einem ersten Schlichtschnitt nur die linken Zahnflanken (7) mit einer bei der Wälzschälbewegung vom Zahnkopf (9) zum Zahnfuß (10) wandernden Spanabtragsstelle (14) und in einem zweiten Schlichtschnitt nur die rechten Zahnflanken (8) mit einer bei der Wälzschälbewegung vom Zahnkopf (9) zum Zahnfuß (10) wandernden Spanabtragsstelle (14) bearbeitet werden.
