Abstract: A gearwheel, wherein the gearwheel has a setpoint geometry, wherein the gearwheel has a modification superimposed on the setpoint geometry in the form of a pitch and/or topography changing from tooth to tooth, wherein a variation of the pitch and/or topography specified by the modification, observed over a total number of teeth of the gearwheel, corresponds to a superposition of at least two harmonic functions, which differ from one another in one parameter or in multiple parameters, such as their amplitude, frequency, or phase shift.

Abstract: A method which is executed in a grinding machine comprising a) rotationally driving a cup grinding wheel around an axis of rotation of a tool spindle at a first speed, b) rotationally driving a dressing tool around an axis of rotation of a dressing spindle at a second speed, c) carrying out a dressing method using the dressing tool, wherein a predetermined, fixed speed ratio is specified between the first speed and the second speed, and after steps (a), (b), and (c): i. eccentrically rotationally driving the cup grinding wheel around the axis of rotation of the tool spindle at a first machining speed using the eccentric drive, ii. carrying out a grinding method, wherein the bevel gear workpiece is machined by grinding using the cup grinding wheel.

Abstract: 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.
