How to process helical gears
Head rotation 20 ° 22 'to complete the work.Note that the angle adjustment is completed, the nose must be locked before they can start rolling work;
2, the installation of the normal displacement angle of 20 ° 22 'hob. This step requires attention, if there is no such forming helical gear hob, you can also loosen the hobbing machine head universal head set screws, the machine
3, the gear blank installed in the turbine mandrel, with a dial indicator to correct its turbine concentricity;
