A method is described for hob grinding helical gearwheels by continuous diagonal hobbing using a tool in the form of a substantially involute worm whose active length is greater than the length of the working area and whose center distance from the gearwheel is changed during its feed motion in the diagonal direction from the axial and tangential directions to generate lateral crowning. The pressure angle of the right or left flanks decreases continuously from a maximum value starting at one end of the worm toward the other end, whereby the maximum pressure angle of the right flanks at one end of the worm coincides with the minimum pressure angle of the left flanks, and vice versa.
