摘要： The invention relates to a method for machining the tip circle diameter of a tooth system (4) of a gearwheel (6), in which the gearwheel (6) rotates about a workpiece axis of rotation (Rw), and in which at least one tooth (9) of the tooth system (4) is machined, by removing chips, by means of a tool (7, 7′) that rotates about a tool axis of rotation (Rz) oriented at an axial distance (A′, A″) relative to the workpiece axis of rotation (Rw). According to the invention, the tool (7, 7′) is disk-shaped, the disk-shaped tool (7, 7′) machines the tip surface (8) of the tooth (9), by removing chips, with at least one partial segment (10a) of its circumferential edge configured as a defined blade (10), wherein a relative movement between the tool (7, 7′) and the gearwheel (6), oriented in the axial direction of the tooth system (4), is carried out during the chip-removing machining, as a consequence of which movement the tool (7, 7′) sweeps over the tip surface (8), and the tool axis of rotation (Rz) is oriented at an axis intersection angle (Σ″) of 5° to 40° with respect to the workpiece axis of rotation (Rw). In this way, efficient and highly precise machining of the tip circle diameter is made possible. The invention also states a method for producing a gearwheel, in which the tooth system (4) is produced on a gearwheel blank (5) by means of hob peeling before machining of the tip circle diameter according to the invention, as well as a combination tool, in which a hob-peeling wheel for producing the gearwheel and a disk-shaped tool for machining the tip circle diameter according to the invention are combined with each other.

摘要： The invention relates to a method for machining toothing systems, in which, for a series of workpieces with an identical target geometry, a toothing system is produced or machined on a respective workpiece in a first machining operation and, in a second machining operation, with a machining tool, additional tooth shaping of the toothing system resulting from the first machining - in particular, chamfering of a tooth end edge of this toothing system - is carried out in a relative positioning with respect thereto, wherein a controller of the second machining operation automatically detects, at least in part, a change in a workpiece property, which is in particular independent of the first machining operation, and/or in a setting of the first machining operation - in particular, with respect to a respectively predetermined reference - and carries out the relative positioning as a function of the detected change.

摘要： A method to form a gear for motor vehicles includes one or more of the following: placing a blank between a first tool member and a second tool member, each of the first tool member and the second tool member having a set of teeth; and moving the first tool member and the second tool member towards the blank while rotating the first tool member and the second tool member to form a gear with a set of teeth from the blank. Each tooth of the set of teeth has a topography that varies tooth-to-tooth.

摘要： A shaving processing method and apparatus for a gear are provided which reduce a load at the time of processing a tooth surface, thereby reducing a transmission error of the gear. Embodiments include a method for finishing the tooth surface of the gear in a state where the gear and a shaving cutter are engaged with each other and the shaving cutter is rotated. The gear has a pair of end surfaces facing each other in the tooth width direction. A first shaving step of processing the tooth surface is performed so that a processing region gradually expands from one end surface of the pair of end surfaces toward the other end surface, and a second shaving step of processing the tooth surface is performed so that a processing region gradually expands from the other end surface of the pair of end surfaces toward the one end surface.

摘要： A hobbing or gear cutting machine uses a rotary tool to rotate a cutting tool around a central axis of the cutting tool. The cutting tool has zero lead cutters, that is, the cutting tool is non-helical. A head holds the rotary tool and moves the cutting tool longitudinally along the central axis of the cutting tool. A workpiece holder holds a workpiece to be machined into a gear proximate the cutting tool. The workpiece holder selectively rotates the workpiece in conjunction with the longitudinal movement of the cutting tool via the head to cut both straight and helical gears from the workpiece.
