Abstract
A method of grinding gears is provided, wherein a workpiece support and a tool base are movable relative to one another for partial movements of the workpiece, for setting the gear teeth data, for accomplishing movements for configuring a tooth profile, and for the to-and-fro lengthwise stroke along the tooth flanks to be ground. A grinding wheel support is mounted at the tool base for pivotable movement about a pivot axis and a grinding wheel is mounted to be rotatably drivable at the grinding wheel support. The axis of rotation of the grinding wheel extends transversely with respect to the aforementioned pivot axis. The grinding wheel support is connected with the tool base by a pivot drive which, during grinding of a tooth flank, enables random changes of the grinding-pressure angle or angle of attack between the grinding wheel and the tooth flank.
