Abstract
A modified classical spinning top (1) and its horizontal driving (6) without mechanical restraining elements are disclosed. The modified classical spinning top has a small permanent magnet (2) on the rotation axis (3), at its upper part and coaxial with it. A second permanent magnet (4) with the opposite polarity to the first one, it means in an attraction configuration, is manually moved horizontally (7) above the top of the spinning top. The interaction of attraction of the two permanent magnets determines a horizontal driving (6) of the spinning top without modification of the rotation movement. The new toy is more interesting, interactive and attractive than the classical one.
Description
Technical field
The present invention relates to a kind of improved traditional gyro (use permanent magnet and do not have mechanical constraint), this gyro can not change under the situation about rotatablely moving by horizontal drive.
Background technology
The well-known people of being like traditional toy: gyro, gyroscope and permanent magnet.
Gyro is ancient toy.They are made with difformity, color and size by timber, metal or plastics.Recently, some in them can produce sound or/and light.But not too many from the outset the change.In case make its rotation, we move with regard to just seeing it.Can not change should move and with its interaction.
Gyroscope is well-known toy and device.Their charming part is how to make direction keep constant.
Permanent magnet is used to use ball, nail, ferromagnetic powder, magnetic fluid and obtains not isostructure.In case realize this structure, can what not take place again then, do not have enjoyment again yet.
Rotatablely move and the design of permanent magnet combination is proposed in the Romanian patent of submitting on February 28th, 1,987 91857 by I.Grosu gyrostatic.By using on rotation traditional gyroscope is improved with coaxial two permanent magnets of traditional gyroscope.Therefore, this gyroscope has angular momentum and magnetic moment.The even external magnetic field that is produced by coil has determined the rotation as Larmor precession.This device has teaching significance and can show how to obtain Larmor precession.This gyroscope simulation has the rotation of the electronics of angular momentum and magnetic moment.
The interesting use of permanent magnet in gyro is suspension gyro (Levitron): U.S. Pat 4 382 245 and U.S. Pat 5 404 062.The dish of gyro is the permanent magnet that becomes to repel structure above second permanent magnet.If satisfy some condition, this gyro can suspend.It is so uneasy to realize suspending.The suspension gyro is produced by www.supermagnete.de.
Another kind of toy is that magnetic UFO gyro has little permanent magnet at the place, bottom that contacts with the ferromagnetic in-plane part.During rotation, this planar member is moved in interesting mode in the bottom of gyro.
Use website www.espacenet.com to select patent: US2004198152, US2003064660, GB2389321, CN1326800 with keyword toy and top and magnet, they have introduced the gyro with permanent magnet.What should emphasize is that all patents all relate to and have uncontrollable dynamic (dynamical) gyro.
Summary of the invention
The present invention is intended to have the gyro of controlled horizontal movement.The dynamics of tradition gyro can not change, and this is because any action that traditional gyro is done is equivalent to torque N, and this torque N will change according to angular momentum theorem and rotatablely move:
dL/dt＝N
Wherein L, N are respectively angular momentum and torque.For moving horizontally this gyro, must apply the active force (to have null torque) of process rotation to it.This can realize by attracting each other of two permanent magnets; A permanent magnet is coaxial with gyro on rotation, and another permanent magnet is positioned at the top of gyro.Abide by accompanying drawing, detailed description and claims and will understand all the elements better.
Description of drawings
Fig. 1 is the total figure that improves gyro.
Fig. 2 is the detail drawing of permanent magnet at the top place of gyro.
Fig. 3 is the collision of two cylindrical shape gyros.
Fig. 4 is the suspension gyro in the rotation.
Fig. 5 is two collisions between the gyro: a gyro has hexagonal shape, and another gyro has cylindrical shape.
Fig. 6 has the gyro of hexagonal shape and the collision between the ball.
The specific embodiment
As previously discussed, all of gyro and permanent magnet make up the controlled dynamics of the gyro of all being unrealized.Can improved gyrostatic dynamics be controlled (I.Grosu, Romanian patent 91857) by using the external magnetic field.Used herein is this design of modified version.Main design is with the coaxial permanent magnet of this tradition gyro traditional gyro being improved on rotation of place, top that is positioned at traditional gyro by use.The external permanent magnets that moves above gyro with manual mode attracts first magnet, thereby moves horizontally this gyro.Because the torque of the attraction between two permanent magnets is zero, does not therefore change and rotatablely move.This situation be because the direction of this power through rotation.Thereby, can control the horizontal translation motion of gyro by the motion of external permanent magnets.Have controlled dynamic (dynamical) gyro more interesting, more joyful, have more education and the science effect.
Abide by Fig. 1 and Fig. 2, be positioned on rotation 3, traditional gyro 1 being improved of place, top of traditional gyro 1 by use with the coaxial little permanent magnet 2 of this tradition gyro 1.Second permanent magnet 4 is arranged in the top of the gyro 5 of rotation.Gyro is followed the horizontal movement 7 of permanent magnet 4 and is moved horizontally 6.Have only when motion 7 and just realize moving 6 slowly the time.When fast moving 7, gyro can not be followed this fast moving 7.Have controlled dynamic (dynamical) gyro and can be used to realize some recreation.Here I propose 3 variants.
First variant relates to the dynamics of gyro.Can be in order to realize moving 6 and move and 7 should have and how soon experimentize.Too fast move 7 and can not realize moving 6.When two gyro close enoughs, they can collide (Fig. 3).Interesting is: after collision, because their collisions once more of Bernoulli's theorem (Bernoulli law).And if permanent magnet 4 close enoughs, then gyro takeoffs and contacts with permanent magnet 4.Continue rotation (Fig. 4).If shake magnet 4 in vertical direction, then well-known is that gyro is fallen on the platform and is rotated further, and can be attracted to magnet 4 once more.Here can observe is how to keep vertical direction.Can not accomplish this point with traditional gyro.
The second, can between hexagon gyro 9 and cylindrical shape gyro 1, realize collision (Fig. 5).Here collision is more violent owing to the shape of hexagon gyro 9.
The 3rd, can realize competition game by using hexagon gyro 9 and ball 10.Ball 10 moves horizontally.Two players everyone make hexagon gyro 9 bump these balls (Fig. 6) so that this ball is moved in the other side's the door.With football, handball, basketball analogy, I am called gyro sphere (TOPBALL) with this recreation.
Can utilize and have controlled dynamic (dynamical) driving gyro and imagine other recreation.
