Description
Technical field
The present invention relates to speed change gear field, more particularly to a kind of passive type variable gears speed change gear.
Background technology
Current speed changer is mostly gear-shift mechanism, and this kind of speed changer will generally arrange in pairs or groups clutch or fluid torque-converter makes
With structure is relative complex, and the continuity of gearshift is bad, and there is pause and transition in rhythm or melody sense in when gearshift.Emerging variable v-belt drive can continuously become
Speed, bending moment, but core institution of its transmission belt as variable v-belt drive, are easily worn part, steel transmission belt often holds
The easily abrasion more serious with the generation of the belt wheel of steel, and the easy season cracking of the transmission belt of rubber material.Now urgently need
A kind of continuously variable and durable stepless speed change device.
Invention content
To solve the above-mentioned problems, the object of the present invention is to provide a kind of passive type variable gears speed change gear, make first
Multiple teeth portion of first gear teeth and second gear on gear different radii engage to realize variable speed.
Based on this, the present invention provides a kind of passive type variable gears speed change gear, including：
First gear is radially equipped with first gear teeth on end face；And
Positioned at the second gear of the wheel flank of the first gear, the second gear can be moved along its axial direction,
The second gear includes ontology and multiple teeth portion around ontology setting, and the fixing end of the teeth portion is connected to described
Body, the movable end of the teeth portion are overlapped on first gear teeth；
First gear teeth squeeze multiple teeth portion and multiple teeth portion are forced to deform upon to form second gear teeth,
First gear teeth and second gear teeth are meshed.
As preference, the gullet depth of first gear teeth increases with the radius of the first gear and is increased.
As preference, the teeth portion is laminated structure, axis co-planar of multiple teeth portion with the ontology.
As preference, axis of the axis of the second gear perpendicular to the first gear.
The passive type variable gears speed change gear of the present invention is equipped with the first gear of first gear teeth including end face and is located at
The second gear of the wheel flank of first gear, the ontology of second gear are equipped with multiple teeth portion, and the fixing end of teeth portion is connected to this
Body, the movable end of teeth portion are overlapped on first gear teeth, and first gear teeth squeeze multiple teeth portion and teeth portion is forced to deform upon, to be formed
Second gear teeth, second gear is by moving first gear teeth and the second gear that make on first gear different radii along its axial direction
Multiple teeth portion engage to realize variable speed.

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 and Fig. 2, the passive type variable gears speed change gear of the present invention is schematically showed, including：The
One gear 1 is radially equipped with first gear teeth 11 on end face；And the second gear 2 of the wheel flank positioned at first gear 1,
Second gear 2 can be moved along its axial direction, and second gear 2 includes the teeth portion that ontology 21 and multiple circular ontologies 21 are set
22, the fixing end 22a of teeth portion 22 is connected to ontology 21, and the movable end 22b of teeth portion 22 is overlapped on first gear teeth 11.Due to teeth portion
22 by first gear teeth 11 extruding, therefore multiple teeth portion 22 deform upon to form second gear teeth 23, first gear teeth 11 and then
It can be meshed with second gear teeth 23.In the present embodiment, teeth portion 22 is pressed against the axis of ontology 21 by first gear teeth 11, is squeezed
Multiple teeth portion 22 that swaging becomes constitute the tooth socket of second gear teeth 23.
Teeth portion 22 is laminated structure, and axis co-planar of multiple teeth portion 22 with ontology 21, the teeth portion 22 of sheet can avoid
Two adjacent teeth portion 22 are interfered with each other in deformation；In order to optimize the structure of the device, the tooth depth of first gear teeth 11
Degree increases with the radius of first gear 1 and is increased, and the axis of second gear 2 is perpendicular to the axis of first gear 1.
In conclusion the passive type variable gears speed change gear of the present invention, the of first gear teeth 11 is equipped with including end face
One gear 1 and the second gear 2 for taking turns flank positioned at first gear 1, the ontology 21 of second gear 2 are equipped with multiple teeth portion 22,
The fixing end 22a of teeth portion 22 is connected to ontology 21, and the movable end 22b of teeth portion 22 is overlapped on first gear teeth 11, first gear teeth 11
It squeezes multiple teeth portion 22 and teeth portion 22 is forced to deform upon, to form second gear teeth 23, second gear 2 is by along its axial direction
Movement makes multiple teeth portion 22 of first gear teeth 11 and second gear 2 on 1 different radii of first gear engage to realize stepless change
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.
