Face motion, the parcel of diabolo and done on the basis of parcel various complexly patterned, comprise a lot
Mechanics principle, its principle is exactly that the direction of the rotary shaft indication of a rotating object is not being affected by external force
Time will not change, wheel turns to be less susceptible to down the soonest, because rotary shaft has one holding level
Strength, play the experience of diabolo according to us, only there is certain rotating speed, diabolo could be kept to take turns
Stablizing of face.
Gyro be one can be around axis of rotation High Rotation Speed, the object that can rotate around other axle again.Top
The key property of spiral shell is gyroscopic inertia, so-called " gyroscopic inertia ", it is simply that when gyrorotor rotate at high speed time,
When not having any moment of face to act on gyroscope, the axis of rotation of gyroscope finger in inertial space
Stablizing constant characteristic, also referred to as stability to holding, its stability is relevant with following physical quantity:
1. the rotary inertia of rotor is bigger, and stability is better；
2. rotor velocity is bigger, and stability is better.
So-called " rotary inertia ", is the physical quantity describing rigid body inertia size in rotation.When
With identical moment be respectively acting on two around the different rigid body of fixed-axis rotation time, the angle that they are obtained
Speed is the most different, and the angular speed that the rigid body that rotary inertia is big is obtained is little, namely keeps
The inertia of original rotary state is big；Otherwise, the angular speed that the rigid body that rotary inertia is little is obtained is big, also
The inertia being just to maintain original rotary state is little.The size of rotary inertia and the quality of rotor, shape etc.
Factor is relevant.Quality is the biggest, and rotary inertia is the biggest；The most along the material of outer rim distribution, it rotates
Inertia is the biggest.
Physical " gyro principle ": gyro is rotating when, and not only the axis around itself turns
Dynamic, but also make coning motion around a vertical axis.It is to say, gyro one side around itself
Axis makees " rotation ", and one side makees " revolution " around vertical axis.Gyro is made " certainly around own axes
Turn " speed of movement velocity, decide the size of gyro angle of oscillation.Turning the slowest, angle of oscillation is the biggest,
Stability is the poorest；Turning the fastest, angle of oscillation is the least, thus stability is the best.Diabolo is around axle
Line rotates and is referred to as rotation, and diabolo rotational velocity is the fastest more easily keeps self enclosing stablizing of rotating about the axis
Property.
At present, the present age, the structure of diabolo all had significant progress with the skill and technique of diabolo, the structure of diabolo
Form has a lot, and the most relatively conventional is bearing diabolo, but diabolo of the prior art, exist
Following problem and defect:

2. raising speed is relatively slow, wastes time and energy, and high speed rotation can not be lasting, and reduction of speed is very fast, and diabolo is difficult to protect
Maintain an equal level steady and control, easily flying out or kinking, hinder oneself and hurt sb.'s feelings, beginner being felt to get started more difficult；
3. the stability rotated about the axis is not strong, and style is few, and the most highly difficult method of trembling turns because of diabolo
Speed is low and cannot show；
4. rotate only one of which rotating speed, so more style can not be played out, also cannot improve and play
