Embodiment
Accompanying drawing discloses the concrete structure of a kind of implementation column of the utility model without limitation, and below in conjunction with accompanying drawing, the utility model will be further described.
As seen from Figure 1: the utility model comprises casing, input shaft 11 and output shaft 14, input small gear 12 on input shaft 11 meshes with the output gearwheel 13 on output shaft 14, in casing, be also provided with auxiliary input gear axle 1, jiggering input gear axle 3, jiggering input gear axle 3 is provided with unsteady intermediate gear 7, the clutch of intermediate gear 7 and jiggering input gear axle 3 is realized in one end of jiggering input gear axle 3 by 3S clutch 4, the other end is realized the clutch of jiggering input gear axle 3 and jiggering motor 6 output shafts by 3S clutch 5; Auxiliary input gear axle 1 is intermeshing by the transition gear 2 on First Transition axle 8 with jiggering input gear axle 3, and the intermediate gear 7 on jiggering input gear axle 3 is intermeshing by the transition gear 10 on the second transition axis 9 with the input small gear 12 on input shaft 11.
In the present embodiment: between two input small gears 12 and input shaft 11, by the spline mating, fixedly mount.
During concrete enforcement: fixedly mount two symmetrical herringbone tooths of the rear formation of input small gear 12 on input shaft 11, output gearwheel 13 herringbone tooths for coupling.Auxiliary input gear axle 1, jiggering input gear axle 3, unsteady intermediate gear 7 and each transition gear all adopt helical teeth, wherein, unsteady intermediate gear 7 is intermeshing by the transition gear 10 on the second transition axis 9 with the input small gear 12 on input shaft 11.
