Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but be not limited to the scope of the present invention.
With reference to shown in Fig. 1 to 3, the active variable gears speed change gear of the present invention is schematically showed, including：First
Gear 1 is radially equipped with first gear teeth 11 on end face；Gear lever 2, gear lever 2 are located at the wheel flank of first gear 1, become
The both ends of fast bar 2 are denoted as first end 21 and second end 22 respectively, and the diameter of gear lever 2 is tapered off by first end 21 to second end 22
Trend, and the side wall of gear lever 2 is equipped with multiple grooves 23 arranged along its axial direction；And second gear 3, second gear
3 are not socketed in rotatably on gear lever 2 and can be slided along the axial direction of gear lever 2, and second gear 3 includes ontology
31 and the teeth portion 32 of multiple circular ontologies 31 setting, the fixing end 32a of teeth portion 32 is connected to ontology 31, the movable end of teeth portion 32
32b is overlapped on the side wall of gear lever 2.The multiple grooves 23 set on the side wall of gear lever 2 force multiple teeth portion 32 that shape occurs
Become, deformation degree of the deformation degree than being only overlapped on the teeth portion 32 on the side wall of gear lever 2 of the teeth portion 32 in groove 23
Bigger, multiple teeth portion 32 that height rises and falls form second gear teeth 33, first gear teeth 11 and then can mutually be nibbled with second gear teeth 33
It closes.Since the linear velocity on 1 different radii of first gear is different, when second gear 3 on gear lever 2 when sliding, second gear teeth
33 can just engage with first gear teeth 11 on the different radii of first gear 1, and variable speed is realized with this.
When second gear 3 slides to second end 22 from the first end 21 of gear lever 2, due to the first end 21 of gear lever 2
Diameter is more than the diameter of its second end 22, and the tip diameter of second gear teeth 33 that multiple teeth portion 32 are formed can continuously decrease,
And in order to which first gear 1 and second gear 3 can be tightly engaged, the stability that it is kept to be driven, the groove 23 of gear lever 2
Depth is tapered off trend by first end 21 to second end 22, correspondingly, the gullet depth of first gear teeth 11 is with the half of first gear 1
Diameter increases and increases, and changes the passive shadow brought to the device transmission stability with this to offset the outside circle of second gear teeth 33
It rings.In addition, because the tooth pitch of first gear teeth 11 is reduced with the radius of first gear 1 and reduced, the groove 23 of gear lever 2
Width is tapered off trend by first end 21 to second end 22 so that second gear 3 slides to second end from the first end 21 of gear lever 2
When 22, the tooth pitch of second gear 3 is gradually lowered, and to coordinate first gear 1, enhances the gear drive stability of the device.
In the present embodiment, the axis of gear lever 2 is preferably perpendicular to the axis of first gear 1；Teeth portion 32 is sheet knot
Structure, axis co-planar of multiple teeth portion 32 with ontology 31, sheet teeth portion 32 can avoid two adjacent teeth portion 32 in deformation
It interferes with each other；Gear lever 2 is preferably cone, i.e. the busbar of gear lever 2 is obliquely installed for one with 2 axis of gear lever
Straight line, certainly, in other embodiment, gear lever 2 or conoid, the i.e. busbar of gear lever 2 are a curve.
In conclusion the active variable gears speed change gear of the present invention, the of first gear teeth 11 is equipped with including end face
One gear 1, the gear lever 2 positioned at 1 side of first gear and the second gear 3 that is set on gear lever 2, in second gear 3
Equipped with multiple teeth portion 32, the movable end 32b of teeth portion 32 is overlapped on the side wall of gear lever 2, when second gear 3 is along gear lever 2
When axial direction slides, the groove 23 on 2 side wall of shape and gear lever of gear lever 2 can force multiple teeth portion 32 that shape occurs
Become to form second gear teeth 33, first gear teeth 11 can be engaged with second gear teeth 33；Make first on 1 different radii of first gear
Multiple teeth portion 32 of the gear teeth 11 and second gear 3 engage to realize variable speed.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and replacement can also be made, these improve and replace
Also it should be regarded as protection scope of the present invention.
