摘要:
A method includes the following method steps: grinding of bevel gears, wherein the respective bevel gears have a straight toothing to be ground, wherein the grinding is carried out by a disk-shaped grinding tool by discontinuous generating grinding using a predetermined rolling ratio. A cutting face of the grinding tool, which rolls during the grinding with teeth of the straight toothing of a respective bevel gear, forms a section of a hollow cone inner surface, and wherein a respective longitudinal crowning is generated on the respective straight toothing of the respective bevel gears by the grinding using the cutting face forming the section of the hollow cone inner surface. The method is distinguished in that the grinding tool is a dressable grinding tool and dressing of the grinding tool is carried out.

A gear-grinding multilayer grindstone includes a rough machining portion and a finish machining portion that are disposed adjacent to each other on a rotational axis. The rough machining portion includes a first core and a rough machining grindstone that is held on the first core. The finish machining portion includes a second core that is adjacent to the first core, and a finish machining grindstone that is held on the second core. The first core and the second core are fixed to each other, without the rough machining grindstone and the finish machining grindstone being fixed at least at outer peripheral portions thereof to each other.

The present disclosure relates to a method for the gear manufacturing machining of a workpiece by a diagonal-generating method, in which the workpiece is subjected to gear tooth machining by the rolling off of a tool, wherein an axial feed of the tool takes place during the machining with a diagonal ratio given by the ratio between the axial feed of the tool and the axial feed of the workpiece. According to the present disclosure, the diagonal ratio is changed within the course of the machining of a workpiece.

Provided is a method of making a barrel-shaped worm-like tool whereby a barrel-shaped worm-like tool capable of efficiently performing grinding without unequal wear can easily be made. The aforementioned method comprises making the barrel-shaped worm-like tool (12) by using a dressing gear (11) to dress the barrel-shaped worm-like tool (12), which is used for machining an internal gear and has a diameter that gradually increases from the ends (12b, 12c) to the center (12a) in the axial direction. On the basis of data wherein the number of teeth is less than that of the internal gear to be machined, the dressing gear (11) and the barrel-shaped worm-like tool (12) are engaged with each other at the same axial intersection angle as during gear-machining performed by the barrel-shaped worm-like tool (12).

The invention relates to a method for the profiling of single-start or multistart grinding worms for profile grinding of gear-teeth according to the principle of continuous generating grinding. The goal of the proposed profiling principle is to position the profiling tool and/or the grinding worm in relation to each other in such a way that different areas of an axial section of the grinding worm thread (referred to as shape elements) can be profiled with different geometric elements of the active area of a profiling tool (referred to as tool elements). According to the invention, for this purpose, with the aid of a coordination matrix a tool element is coordinated with each shape element of an axial section of the grinding worm thread. The coordination criteria applied in this regard are, in particular, short profiling time and flexible changing of the shape elements. Tool elements that lead to a punctiform contact between the worm thread and the profiling tool are coordinated with shape elements of the worm thread axial section that must be flexibly changeable. On the other hand, longer shape elements are profiled by means of the more productive line contact. For the positioning of the grinding worm and the profiling tool in relation to each other, besides the linear axes known with respect to the profiling of grinding worms, for achieving the shifting and feeding movement, swivelling axes are also used for swivelling the profiling tool and/or the grinding worm.
摘要:
A tool for producing crown wheels by means of a generating process comprises a disc which is rotatable about its axis, with machining elements which are provided on the periphery thereof and the cutting edges of which lie in the outer surface of a profile determining the shape of the teeth of a crown wheel to be produced with the tool, said profile extending essentially helically over the periphery of the disc. In each cross-section of the helical profile the outer contour (25) of the cross-section is at least of a part of the outer contour of the tooth profile of an imaginary gear wheel (23) with involute teeth and preferably straight lines connecting thereto, in such a way that in the case of each of the teeth (22) with a tooth tip and two tooth flanks bounded by the outer contour (25) of the cross-section the distance between each of the two tooth flanks and a line at right angles to the axis of rotation of the tool and passing through the tooth tip remains the same or increases from the tooth tip to the axis of rotation of the tool.
