A) installing drive bevel gear on power shaft, driven wheel of differential axle is installed driven wheel of differential, drive bevel gear engages with driven wheel of differential；
B) primary planet wheel is arranged on output pivoted frame by one-level cantilevered planet bearing pin, and primary planet wheel engages with one-level sun gear and one-level ring gear simultaneously；
C) two grades of cantilever mounted formula planet bearing pins are fixed on casing, secondary planet wheel is by bearings on two grades of cantilever mounted formula planet bearing pins, and secondary planet wheel engages back wall around two grades of cantilever mounted formula planet bearing pin rotations with two grades of ring gears of secondary solar gear and floating simultaneously；
D) driven wheel of differential axle is located by connecting with one-level sun gear by barreled tooth flank set, one-level ring gear is connected with secondary solar gear by one-level flexible torque joint cover, the two grades of ring gears floated are connected with output pivoted frame by two grades of flexible torque joint covers, and output pivoted frame is provided with plain thrust bearing with casing joint portion；
E) output pivoted frame transmission moment of torsion is jointly driven by two grades of ring gears of one-level cantilevered planet bearing pin and floating.
In this utility model: described drive bevel gear and driven wheel of differential are hardened face gear, its tooth is circle-arc tooth system or crin root Bel's tooth system.
In this utility model: all including at least three planetary gears being evenly distributed on around sun gear in described primary planet train and secondary planet train.
The utility model has the advantage of: owing to Vertical Mill gear-box uses differential planetary power dividing type structure, make two-stage planet all as output transmission load, compared with the output of current Vertical Mill gear box structure single-stage planetary, improve the bearing capacity of gear-box significantly.In the secondary planet wheel train structure that gear-box stress is maximum, bearing pin is fixed, and reality is fixed shaft gear train structure, is effectively increased the reliability of gear-box.Gear box structure is compact, and power density ratio is big, has saved substantial amounts of material cost.And gear-box ratio coverage is big, can preferably meet market demands.
