The gear-hobbing machine mainly is uses in processing the cylindrical gears and the worm gear, in processes the machine hold the very important status. But at present our countrys gear-hobbing machine development relatively is also backward, the entire industry productive forces level has been enormously limited, therefore we must carry on.NrpoJac3v1 The main issue isthe differential motion mechanism, the gear swing frame for feeding and the dividing spindle.Helical rolling will have the use of the differential motion mechanism,it is located in the side of the gearbox,the top side of the square head is a machine tool table light bars,square head is below the first axis of the active differential gear shaft.And there are the differential transmission, the dividing spindle,and the gear dividin
