Method for machining gearwheels

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