Description
Technical field
The present invention relates to Popular Science Education technical field more particularly to a kind of science popularization devices for demonstrating gearbox principle.
Background technique
Planetary transmission is the most common structure of hydraulic automatic speed variator, and planetary transmission belongs to a kind of tooth
Roller box, it is made of planetary ring gear, sun gear, planetary gear (also known as satellite wheel) and gear hub, according to gear ring, sun gear and
The movement relation of planetary gear, may be implemented input shaft and output shaft be detached from positive drive relationship, input shaft and output shaft in the same direction or
Reverse drive and input change with output shaft transmission ratio.The planetary gear mechanism used in automatic gear-box, using more
There are Simpson's (Simpson gearset) gear mechanism and La Weinaierhe (Ravigneauxgearset) gear mechanism.La Wei
Nai Erhe (Ravigneauxgearset) gear mechanism is a kind of combined type planetary gear mechanism, it is by a single planet wheel
Planet row and a double-planet wheel type planet row are composed: rear sun gear and long planet pinion, planet carrier, rim gear wheel are common
Form a single planetary bevel gear.In science and technology center at this stage, not having also and participate in interacting by spectators, operation speed changer realizes speed change,
The specific structure of intuitive observation speed changer, understands the science popularization device of speed changer principle in depth.
Summary of the invention
A kind of science popularization of the demonstration gearbox principle designed it is an object of the invention to overcome the deficiencies in the prior art fills
It sets.
In order to solve the above technical problems, the present invention adopts the following technical scheme that:
A kind of science popularization device for demonstrating gearbox principle, including exhibition booth and the Display Rack being located on the exhibition booth, in the exhibition
Frame is equipped with planetary transmission model and rotation hand wheel, and the planetary transmission model is by sun gear, planetary gear, tooth
Circle and planet carrier are constituted, and the rotation hand wheel is divided into the first rotation hand wheel and the second rotation hand wheel, first rotation hand wheel with
Sun gear is connected, and the planetary gear is connected between the sun gear and gear ring by gear, and the planetary gear is mounted on planet
On frame, second rotation hand wheel is connected to lever mechanism by bearing, and the lever mechanism includes connecting rod, the connecting rod activity
It is mounted in fixing seat, one end of the connecting rod is equipped with spring, and the other end is connect with the bearing.
Compared with prior art, the invention has the benefit that
A kind of science popularization device for demonstrating gearbox principle of the present invention, spectators observe gear shift by rotation rotation hand wheel
The structure change of case understands the principle of speed changer.

Specific embodiment
Referring to shown in attached drawing 1-5, a kind of science popularization device for demonstrating gearbox principle, including exhibition booth 1 and it is located at the exhibition booth 1
On Display Rack 2, on the Display Rack 2 be equipped with planetary transmission model and rotation hand wheel, the planetary transmission mould
Type is made of sun gear 3, planetary gear 4, gear ring 5 and planet carrier 6, and the rotation hand wheel is divided into the first rotation hand wheel 7 and the second rotation
Wheel 8 is changed hands, first rotation hand wheel 7 is connected with sun gear 3, and the planetary gear 4 is connected to 3 He of sun gear by gear
Between gear ring 5, the planetary gear 4 is mounted on planet carrier 9, and second rotation hand wheel 8 is connected to Lever machine by bearing 8-1
Structure, the lever mechanism include connecting rod 8-2, and the connecting rod 8-2 is movably arranged on fixing seat 8-3, one end of the connecting rod 8-2
Equipped with spring 8-4, the other end is connect with the bearing 8-1.
A kind of science popularization device for demonstrating gearbox principle of the present invention, spectators pass through the first rotation hand wheel 7 of rotation, the first rotation
The rotation of handwheel 7 drives the sun gear 3 being attached thereto to rotate, due to the company of being mutually twisted between sun gear 3, planetary gear 4 and gear ring 5
It connects, just mutually rotation between 5 three of sun gear 3, planetary gear 4 and gear ring at this time；Spectators can also pass through rotation the second rotation hand
8 control planetary gear 4 of wheel and gear ring 5 do not follow rotation, and particular by the second rotation hand wheel 8 of rotation, the second rotation hand wheel 8 turns
The dynamic connecting rod 8-2 being attached thereto that will drive is contradicted onto star-wheel 4 or gear ring 5, make its some in stationary state, rotate the again
Two rotation hand wheels 8 drive the rotation of sun gear 3 or directly rotate gear ring 5 or pass through the rotation star-wheel 4 of planet carrier 6, discovery sun gear 3,
Mutual driving rotation between planetary gear 4 and gear ring 5 certain two, to observe the gear variation of its planetary transmission.
The above description is only the preferred embodiments of the present invention, is not intended to limit the present invention in any other form,
Any person skilled in the art is changed or is modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment.But without departing from the concept of the present invention, above embodiments are done according to the technical essence of the invention
Any simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
