In cover, the planetary gear in described differential gear set is rotated by described driven gear, in described differential gear set
The wheel shaft of axle shaft gear extend out to respectively outside described translucent cover and be connected from different runners respectively.
Each gear may be contained within a base, and wherein the one end at described base is provided with the first support plate, described active
Bevel gear and rocking bar may be contained within described first support plate.
Be provided with a power transmission shaft and two the second support plates at the middle part of described base, described power transmission shaft passes through two second
Plate supporting is arranged on described base, and described driven wheel of differential and described driving gear are installed on described power transmission shaft.
Described base is provided with two the 3rd support plates away from one end of described rocking bar, and described translucent cover passes through said two the 3rd
Support plate supporting is arranged on base.
It is equipped with pad between described axle shaft gear and described translucent cover and between described planetary gear and described translucent cover
Sheet.
Advantage of the present utility model with good effect is:
1, this utility model can allow student's manual operation in person, to be more fully understood that structural principle and the work of differential mechanism
State.
2, this utility model is simple and compact for structure, facilitates observation of students to learn.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 is rocking bar, and 2 is drive bevel gear, and 3 is driving gear, and 4 is driven wheel of differential, and 5 is planetary gear, and 6 are
