Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment one, please refers to Fig. 1~3, a kind of anti-gear interlocking structure of two grades of speed changes of single motor, including input motor 1,
Motor input gear 2,6, two grades of 3, one grades of first stud gear, 4, one grades of A transmission gear B transmission gear 5, output gear speed changes
Gear 7, unilateral bearing 8, the motor input gear 2 are connect by motor shaft with input motor 1, and input motor 1 is for driving
