Large Gyroscopic and production method
Technical field
The present invention relates to toy gyroscopes, especially " Large Gyroscopic and production method ", are a kind of using economic material system
Make Large Gyroscopic.
Background technique
Currently, the Large Gyroscopic price of gyro in the market is more expensive, because the gyro being relatively large in diameter, either uses timber
Production still makes of metal, and material cost is all very high, and relevant information showed that very heavy gyro cost reached more than 100,000.China
Number of patent application: 201510651527.5, " a kind of gyro ", gyroscope body, handle, toroidal cavity, the gyroscope body
A vertical fixed handle at center on upper surface, the gyroscope body is interior to be equipped with a toroidal cavity, the annular
The filling in the underface of handle, the toroidal cavity of the center of circle of cavity is full.This patent application uses liquid water annular
Cavity is filled, to high-speed rotating gyro, what liquid water played the role of gyro is to slow down, and the height of toroidal cavity
Degree and thickness be it is the same, not can increase the rotary inertia of gyro.Chinese Patent Application No.: 201620046717.4, it is " new-type
Gyro " is equipped with up big and down small conical cone at the body bottom portion center of novel gyro, is provided at gyroscope body center side
Groove, the translucent cover box of annular is cased in groove, and translucent cover box is provided with luminous filler.Do not stalled in gyroscope body it is dynamic, thoroughly
Bright cover box and the internal capable of emitting dazzling brilliance of luminous filler, improve the interest of gyration.It is mentioned in this patent application
Translucent cover box and luminous filler be all the lighter object of specific gravity, not can increase the rotary inertia of gyro.Translucent cover box
Ring-like circle can only play beautiful effect, and translucent cover box is also easily broken.
Summary of the invention
In order to further improve gyro series and production method, the present invention tries hard to provide a kind of Large Gyroscopic and production side
Method.
The technical solution adopted by the present invention to solve the technical problems is: Large Gyroscopic, is fixed with steel below gyrostat
Pearl, it is characterized in that: being filling space between the outer wall and inner wall of gyrostat, filling space is a ring structure, fills space
Loop height be greater than annular thickness, filling space be close to gyrostat outer diameter at, filling space in adhesives with add
Heavy material filling, the upper surface of gyrostat are equipped with cover board, and there is cavity in the centre of gyrostat, there is ball unit below gyrostat.With
Epoxy resin uses iron sand to modulate obturator as weighting material as adhesives, or uses cement as adhesives, uses sand
Son modulates obturator as weighting material.One layer of stainless steel sleeve is covered in the outer wall of gyrostat.
The production method of Large Gyroscopic, it is characterized in that: the plastic mould of gyrostat is made first, with injection molding on injection molding machine
Mode form;Obturator is modulated with adhesives and weighting material, obturator injection is filled in space, then covers cover board, is filled out
Ball unit is installed after filling soma admittedly.The Mass Distribution of obturator is close at the outer diameter of gyrostat, to turn far from rotation axis
Dynamic inertia increases, and plays the role of flywheel.
The invention has the advantages that the production method of Large Gyroscopic, using common, cheap material, by gyrostat
A hollow structure is made, the loop height in filling space is greater than the thickness of annular, and the outer of gyrostat is close in filling space
At diameter, fills in space and bond production with biggish, common, the cheap material of specific gravity, so that Large Gyroscopic cost of manufacture is non-
It is often low.The Mass Distribution of obturator is close at the outer diameter of gyrostat, far from rotation axis rotary inertia is increased, plays flywheel
Effect, gyro performance is improved.One layer of stainless steel sleeve is covered in the outer wall of gyrostat, can also there is extraordinary presentation quality.
Detailed description of the invention
Fig. 1 Large Gyroscopic schematic diagram.

Specific embodiment
Large Gyroscopic in the figure is fixed with steel ball below gyrostat, it is characterized in that: the outer wall of gyrostat 2 and inner wall 3
Between be filling space 4, filling space 4 be a ring structure, filling space 4 loop height be greater than annular thickness, fill out
It fills space 4 to be close at the outer diameter of gyrostat 2, be filled in filling space 4 with adhesives and weighting material, the upper surface of gyrostat 2
Equipped with cover board 5, there is cavity 6 in the centre of gyrostat 2, there is ball unit 1 below gyrostat.Use epoxy resin as bonding material
Material uses iron sand to modulate obturator as weighting material, or uses cement as adhesives, and sand is used to modulate as weighting material
Obturator.One layer of stainless steel sleeve is covered in the outer wall of gyrostat 2.It seems more attractive, also more improves the intensity of gyrostat.To see clearly
Internal structure, gyrostat 2 have been cut away half.
The production method of Large Gyroscopic, it is characterized in that: the plastic mould of gyrostat 2 is made first, with note on injection molding machine
The mode of modeling forms;Obturator is modulated with adhesives and weighting material, obturator injection is filled in space 4, then covers cover board
5, ball unit 1 is installed after obturator is solid.The Mass Distribution of obturator is close at the outer diameter of gyrostat 2, far from rotation axis
So that rotary inertia increases, play the role of flywheel.
