Diabolo is a kind of actual life application of gyro principle, the parcel of the startup of diabolo, acceleration, stable plane motion, diabolo and do on parcel basis various complexly patterned, comprise a lot of mechanics principles, the direction of the rotating shaft indication of its principle rotating object is to change when not affecting by external force, wheel turns more be not easy down more soon, because rotating shaft has the strength of one maintenance level, the experience of diabolo is played according to us, only have and there is certain rotating speed, the stable of diabolo wheel face could be kept.
Gyro be one can around axis of rotation High Rotation Speed, the object that can rotate around other axle again.The key property of gyro is gyroscopic inertia, so-called " gyroscopic inertia ", be exactly when gyrorotor is with High Rotation Speed, when acting on gyroscope without any moment of face, the sensing of the gyrostatic axis of rotation in inertial space keeps stablizing constant characteristic, also referred to as stability, its stability is relevant with following physical quantity:
1. the rotary inertia of rotor is larger, and stability better;
2. rotor velocity is larger, and stability better.
So-called " rotary inertia " is the physical quantity describing the inertia size of rigid body in rotation.When acting on two different rigid bodies around fixed-axis rotation respectively with identical moment, the angular speed that they obtain is generally different, and the angular speed that the rigid body that rotary inertia is large obtains is little, namely keeps the inertia of original rotary state large; Otherwise the angular speed that the rigid body that rotary inertia is little obtains is large, namely keeps the inertia of original rotary state little.The size of rotary inertia is relevant with factors such as the quality of rotor, shapes.Quality is larger, and rotary inertia is larger; Material along outer rim distribution is more, and its rotary inertia is also larger.
Physical " gyro principle ": gyro is when rotation, and the axis not only around itself rotates, but also makes coning motion around a vertical axis.That is, gyro one side does " rotation " around the axis of itself, and one side does " revolution " around vertical axis.Gyro makes the speed of " rotation " movement velocity around own axes, decides the size of gyro angle of oscillation.Turn slower, angle of oscillation is larger, and stability is poorer; Turn faster, angle of oscillation is less, and thus stability is also better.Diabolo encloses to rotate about the axis and is called rotation, and diabolo rotational velocity more easily keeps self enclosing the stability rotated about the axis more soon.
At present, the structure of contemporary diabolo and the skill and technique of diabolo all have significant progress, and the version of diabolo has a lot, wherein comparatively commonly bearing diabolo, but diabolo of the prior art, and there are the following problems and defect:
1. diabolo is in dither process, trembles line and can not walk full, tremble line use ratio not high;

Further, the quantity of this planetary gear diabolo assembly is 4, specifically see Fig. 2.
This first holds wire casing 9, second and holds wire casing 13, the 3rd and hold wire casing 5 and the 4th and hold wire casing 18 in U-shaped or V-shape, can meet different diabolos and tremble line demand.The diameter of this central gear 2 is greater than the diameter of described planetary gear 16.This sun gear disk whistle 4 is different from the whistle mouth quantity on the planetary gear disk whistle 17, and ring number different, when pulling shake, pronounce in each whistle simultaneously, loud and sonorous forceful.The rotating speed of diabolo is higher, and air is larger to the gas column excitation power in diabolo air chamber, and its sound sent is also larger.
When this planetary speed change diabolo running, the multiple planetary gear diabolo assemblies of empty set on planet carrier 10, can rotate around the axis of oneself on the one hand, can rotate around central gear 2 with planet carrier 10 again on the other hand, have rotation and revolution two kinds of motion states concurrently.In planet row, there are three primary elements that the central gear 2 of fixed axis, ring gear 8 and planet carrier 10 are called planet row, different connections and fixed solution can obtain different gearratios, the various combination of three primary elements can have 6 kinds of different assembled schemes, add directly gear transmission and neutral, have 8 kinds of combinations, phase should be able to obtain 5 kinds of different gearratios.Simple planetary arrangement has two frees degree, so there is no the gearratio fixed, and can not be directly used in gear.In order to form the transmission mechanism with a stable drive ratio, in these three primary elements of central gear 2, ring gear 8 and planet carrier 10 one must be fixed, or make it move to be subject to certain constraint, also can certain two primary element be connected to each other together, planet row is become only have the mechanism of one degree of freedom, obtain the gearratio determined.Simple planetary arrangement is by fixing different element or change interlock connection, can draw different drive states.When shaking this planetary speed change diabolo, by being positioned over different holding on wire casing on planetary gears trembling line, thus change rotating speed, to adapt to different styles and the muscle power of the person of trembling.In operating process, when shaking planet diabolo 14, feel the most laborsaving; When shaking planet carrier diabolo 12, feel to require great effort most.The effect of diabolo speed change system is exactly agree by change in shake planetary gears multiple the speed that wire casing changes diabolo rotating speed mutually.
In planetary gears, central gear 2 number of teeth is minimum, and the virtual number of teeth of planet carrier 10 is maximum, and ring gear 8 number of teeth between.The various motion conditions of planetary gears is analyzed as follows:
1. when planet carrier 10 is fixed: central gear 2 rotates clockwise as driving link, planet carrier 10 is fixed, this mechanism belongs to dead axle transmission, then the rotation direction of ring gear 8 is contrary with central gear 2, ring gear 8 is as the counterclockwise underdrive of Passive part, planetary gear 16 plays the effect of transition wheel, changes the rotation direction of Passive part ring gear 8, so planetary gear 16 speedup rotation counterclockwise.
Using on planet carrier 10 wherein any one planetary gear 16 rotates clockwise as driving link time, central gear 2 counterclockwise underdrive, ring gear 8 is underdrive clockwise, drives other planetary gears 16 on planet carrier 10 also synchronously to slowly run clockwise.Now planetary speed change diabolo is rotated the slowest, and toggle speed is slow, needs fast jitter stick shaker, and improve rotating speed, exercise intensity is large.
Ring gear 8 rotates clockwise as driving link, and planetary gear 16 clockwise speedup rotates, and central gear 2 counterclockwise speedup rotates.
2. when central gear 2 is fixed: planet carrier 10 rotates clockwise as driving link, ring gear 8 rotates as the clockwise speedup of Passive part, planetary gear 16 under the drive of planet carrier 10 around central gear 2 center line revolution while, also in clockwise speedup rotation, belong to maximum gear driven pinion, be the motion of a kind of speedup and there is minimum gearratio, now planetary speed change diabolo rotating speed is the highest, toggle speed is the fastest, acceleration is maximum, stick shaker chattering frequency is low, and gyroscopic inertia is best, the most stable.
Ring gear 8 rotates clockwise as driving link, and planet carrier 10 is as the clockwise underdrive of Passive part.
3. when ring gear 8 is fixed: central gear 2 is as driving link and rotate clockwise, planet carrier 10 is as the clockwise underdrive of Passive part, planetary gear 16 under the drive of planet carrier 10 around central gear 2 center line revolution while, also in counterclockwise speedup rotation, central gear 2 drives planet carrier 10 rotation to belong to pinion and drives maximum gear, is a kind of retarded motion and has maximum gearratio.
When planet carrier 10 rotates clockwise as driving link, central gear 2 rotates as the clockwise speedup of Passive part, planetary gear 16 under the drive of planet carrier 10 while the revolution of central gear 2 center line, also in counterclockwise speedup rotation.
Be more than for single-wheel diabolo, this planetary speed change diabolo is applicable to Two-wheeled diabolo too.Every once shake of this planetary speed change diabolo all allows diabolo that line is walked completely, and make the utilization rate of line reach the highest, once push up twice, rotating speed has got on, and can save many strength for user.
