Further, described the first axle, the second axle, the 3rd axle, the 4th axle, the 5th axle, the 6th axle are arranged in same Gearbox, and described Gearbox is provided with speed reducing box base.

The beneficial effects of the utility model are: the first axle, the 4th axle are driven by two motors, in same level, facilitate motor debugging, and the 3rd axle, the 6th axle are up and down to be arranged, drives respectively the roll of arranging up and down.

Two sets of transmission mechanism of the present utility model combine on a speed reducer, share a speed reducer base, and internal gear is arranged and staggered, and prevents from interfering, and arranges with minimum space, be independent of each other, and complementary interference.

Reducing transmission structure of the present utility model, rolling power utilization ratio is high, loses littlely, and power of motor is little, easily buying, cost, utilization efficiency is high.Double-deck speed reducer is by two speed reducers and become one, two outputs of two inputs, completely independent, power of motor is the half of the power of single-input double-output speed reducer, does not need shunting, effect of rolling is good, cost is also low, and volume and floor space all less.
