METHOD FOR GRINDING OF BEVEL GEARS
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.
Method for finish machining of a bevel gear in a region of a tooth head, machine for machining bevel gears, and grinding tool for use in association therewith
Methods for machining may include: (a) providing a bevel gear on a workpiece spindle of a machine, the gear having a tooth having a head, (b) rotationally driving the gear about an axis of the spindle, (c) providing a first machining tool on a tool spindle of the machine, (d) machining the gear by means of the first machining tool, (e) providing a grinding tool as a second machining tool on the tool spindle or on a further spindle, (f) driving the grinding tool to rotate about a tool axis of the tool spindle, wherein the grinding tool comprises a concave machining region that has a ring shape and is arranged concentrically in relation to the tool axis, and (g) advancing the grinding tool in relation to the gear to bring the machining region into chip-removing operational connection with an edge in a region of the head to produce a chamfer on the edge by grinding.
