Chapter 420 Magnetic Bearing Joints

Han Yuan also knew the importance of the magnetic bearing joint, so after the assembly of the parts under the sole of the foot was completed, he deliberately slowed down the assembly of the magnetic bearing joint.

In fact, he has no choice but to slow down. Compared with other components, the magnetic bearing joint used for the connection is quite complicated to manufacture.

Magnetic bearing joints are assembled manually, not directly processed by CNC equipment.

Although a large part of the assembly parts it uses is processed by CNC equipment, the assembly process cannot be mechanized for the time being.

From the previous drawings, we can know that the magnetic bearing joint is composed of three parts, similar to the human phalanx, with a ball interspersed between the upper and lower phalanx.

And these three parts have magnetic wires with a rather complicated structure.

The weaving of these magnetic wires cannot be automatically weaved and fixed based on the current robotic arm technology and intelligent programs owned by South Korea.

This step can only be done manually by him.

From a large pile of parts, Han Yuan found the parts he needed.

A hollow sphere, a bunch of miniature stators, rotors, and a bunch of thin β-sensitive magnetic wires.

Showing the materials in his hand in front of the camera, Han Yuan said, "These in my hand are one of the core materials for making magnetic bearing joints."

"Stator and rotor are familiar to everyone, and there are these parts in generators and motors."

"And this slender silver-gray metal wire is a variant of the magnetic-sensitive wire."

"As for the magnetic sensitive wire, if you still remember, it is the material used in the manufacture of electric propulsion-free fluid motors. It is a metal wire wound by a combination of single crystal copper wire and silver wire."

"Beta-magnetowire is a variant of it, as is common nickel metal and gamma nickel."

"Compared with ordinary magnetic-sensitive wires, β-magnetic-sensitive wires do not have the excellent electrical and signal transmission properties of magnetic-sensitive wires, but they have super-strong electric-magnetic energy conversion characteristics at room temperature."

"It can convert the current into a super-strong magnetic field after being wound into a specific coil."

"Although ordinary metals such as copper and iron also have this characteristic, the degree to which β-sensitive magnetic wire can achieve is several times or even ten times that of the former."

"That is, under the same strength of current and voltage, the coil of β-sensitive magnetic wire around the city can provide a stronger magnetic field."

"This is one of the core materials for magnetic bearing joints."

Hearing this, the audience in the live broadcast room looked curiously at the slender metal wire covered in a brown film in Han Yuan's hand.

[Sensitive magnetic wire?I have the impression that it seems to be something used in a "three-electrode ion generating device". 】

[Magnetic wires are purple and silver, right?Why is this brown. 】

[I remember this thing, I watched the anchor pester this thing for a long time. 】

[Upstairs, you remember wrongly, that is tetrayttrium barium copper oxide high-temperature superconductor, and the magnetic sensitive wire is the one stuffed into the metal ring. 】

[To be honest, the electric propulsion engine is simply super black technology. Without this anchor, it would take another 100 years for human beings to make it. 】

[Upstairs, you underestimate human beings, don’t you?Besides, this anchor is also human. 】

[Speaking of which, I’m curious. If we count according to our calendar, it’s 2022, so what year is the anchor? 2222?Or 3222? 】

[At least it is human beings after 500 years, right? 】

[500 years?If you say 5000 years, I will believe it! 】

[Anchor anchor, tell me which year you are from?Or what is the situation in which parallel world you are in? I am quite curious. 】

[Not to mention anything else, I just want to ask, is there a Great Cold Nether Kingdom over there? 】

【Great Cold Nether Kingdom: The universe is made by us, do you think there is one? 】

The brief explanation immediately aroused the curiosity of the audience and experts from various countries in the live broadcast room, but the memory of netizens was only seven seconds.

The topic at the beginning became something else after chatting.

Han Yuan looked at the barrage, smiled and bypassed the parallel world, and continued:

"Just like the 'three-electrode ion generator' in the electric propulsion impermeable engine, the β-sensitive magnetic wire used in the magnetic bearing joint needs to be braided by hand."

"In addition to the weaving method and special fixing method, the softness of the β-sensitive magnetic wire and the weak coating on the outer layer are also doomed to the failure of mechanized mass production of robots using magnetic bearing joint technology."

"In this way, the X-1 magnetic bearing servo humanoid industrial robot is actually quite interesting."

"If it is going to be mass-produced, it requires a lot of manpower to handle and manufacture the most critical magnetic bearing joints."

Hearing this, the audience in the live broadcast room were a little confused, and immediately reacted.

[Crap, this is it. 】

[What the hell, isn’t the purpose of the robot I created to replace manpower?Why does it still require a lot of manpower to manufacture? 】

[It is equivalent to exchanging manpower for machinery, and then replacing manpower with machinery. 】

[After going around in a circle, it's better to use human power to do it directly. 】

[Sounds like a trick, but compared to what the X-1 robot can do and how long it can be used, it should be worth it. 】

[That depends on how long a magnetic bearing joint can be used. If it can only be used for a few months and needs to be replaced, then what's the point. 】

[Magnetic bearing joints, as long as they are not artificially damaged, or used under heavy loads, then they can be used for a long time, after all, they have no wear and tear. 】

[Although the reasoning is correct, I still feel cheated. 】

[Pure manual robot! 】

The audience in the live broadcast room were full of complaints, talking about such things as magnetic bearing joints.

Even countries around the world were stunned. No one would have thought that the most critical magnetic bearing joint on this so-called X-1 industrial robot was actually made by hand.

It sounds unbelievable that a top-notch industrial robot is actually handcrafted.

After all, compared with automated intelligent machines, the accuracy of manual work is indeed a bit far away.

Although in modern society, handmade represents expensive.

But that's not to say that handmade things are top-notch.

At least in terms of industrialization and mechanization, if manual work is used, it is basically acquiesced that it is backward.

But looking back, this is not the first time this kind of thing has happened to this anchor.

When manufacturing the electric propulsion-free propellant engine before, the 'tetrayttrium barium copper oxide high temperature superconductor' wire winding on the three-electrode ion generating device inside was hand-woven by him.

That step has hurt a lot of countries.

Not all countries have the same talents in hand weaving as Hua.

And at that time, because of the importance of electric propulsion-free engine, no country dared to make a move on the reproduction process.

All the steps are done according to the actions of this anchor. Whatever method he uses, the method used by various countries is used to restore it as much as possible to avoid problems caused by changing any steps.

But later, after the first copy was successful, countries began to try to improve or optimize the electric propulsion engine.

It was only when I arrived here that I discovered that the tetrayttrium barium copper oxide high-temperature superconductor wires on the original three-electrode ion generator can be wound mechanically.

Not only will it not be affected, but even because the precision of mechanized winding is higher than that of manual winding, the operating efficiency of the three-electrode ion generating device is also higher.

This leads to better performance of the electric propulsion-free working medium engine.

This discovery almost did not make the brains of all countries spit out.

Han Yuan didn't know the thoughts of various countries. After explaining the place where the magnetic bearing joint needs to be manufactured, he began to wind and process the coil.

The most critical part of the magnetic bearing joint is to manufacture a horizontal and vertical electric shaft device inside the spherical shape.

This step is simple and simple, but complicated and complicated.

The coil structure arranged on the inner surface of the sphere is a key point that affects the final magnetic field strength.

How to arrange the horizontal and vertical electric shaft devices needs to be determined according to the installation position of the magnetic bearing joint.

The strength and thickness of the coil will affect the final magnetic field and control.

The electric field force is proportional to the electric field strength, electric displacement and electrode area, and the magnetic field force is proportional to the magnetic field strength, magnetic induction strength and magnetic pole area.Therefore, a certain bearing capacity and stiffness can be obtained by properly selecting the electric field or magnetic field parameters and geometric dimensions.

Whereas electrostatic attraction or magnetic attraction is inversely proportional to the square of the distance between objects.

According to Anner Hugh's theorem, this static system is statically indeterminate. In order to make the electromagnetic bearing work stably, it must be controlled by means of servo devices or adjusting circuit parameters.

For example, the joints at the ankles have to bear the weight and load of the entire robot, so the thickness, strength, number of turns and length of the β-sensitive magnetic wires used in the magnetic bearing joints arranged here are all higher than those required by the wrists. higher.

Thanks to Won's knowledge and information, which contains various detailed data, there is no need to try bit by bit like ordinary scientific research, to accumulate experience and calculation bit by bit.

Having a complete data source, he just needs to remember every parameter and apply it.

After securing one half of the magnetic bearing ball on the bench, Won picked up the beta-sensitive magnetic wire and began to secure it inside the ball in a specific order and angle.

These β-sensitive magnetic wires coated with an insulating layer are quite soft and can be easily bent into various shapes.

But pay special attention when winding and crimping, once the β-sensitive magnetic wire is bent too high, it will cause the upper insulation layer to fall off, which will cause damage.

Once the insulating paint on the top falls off, the mild consequences will cause the magnetic bearing joint to fail, and the severe ones will be burned directly.

According to the corresponding length and number of turns given in the knowledge information,
According to the standard data, the β-sensitive magnetic wire is wound and fixed inside the hollow sphere.

Different from the winding of tetrayttrium barium copper oxide high-temperature superconductor wire, the winding of β-sensitive magnetic wire requires that each winding point be dense and have no gaps.

In addition to this, overlapping operations are also required.

This step alone took more than ten minutes to complete.

This is still in the case of his super hands-on ability and control ability. If it is an ordinary person, it is estimated that the magnetic sensitive wire inside will be destroyed before the first winding of the coil group is completed, which will lead to a restart.

After spending more than half an hour, Han Yuan finally fixed all the β-sensitive magnetic wires required by the horizontal and vertical electric shaft devices in the ball.

After fixing the β-sensitive magnetic wire, the next step is to install the rotor and stator inside the ball.

Compared with fixing the β-sensitive magnetic wire, this step is much simpler, but the workload is not much less.

Because in a ball, at least four miniature stators need to be installed.

As for the magnetic bearing joint deployed in places like the ankle, the number of miniature stators required in it reaches eight.

These eight stators are respectively fixed inside the balls which are only the size of a baby's fist, which shows that the difficulty is quite high.

The main function of these stators is to rotate the magnetic field, while ensuring that the internal magnetic force will not leak out.

The main function of the rotor is to be cut by the magnetic force lines in the rotating magnetic field and then output current to make the entire magnetic bearing joint work.

The miniature stator and rotor are welded by small electric welding and installed on the outer coil. After the eight stators are installed in eight different directions, the central rotor is embedded in it.

Finally, the two petals of the ball are assembled to form a whole ball, and the gap at the assembly joint is closed.

In this way, the ball assembly for the center of the magnetic bearing joint is preliminarily manufactured.

After manufacturing the ball assembly of the magnetic bearing joint, Han Yuan put down the tool in his hand and took it off the experimental table.

This thing that took him more than an hour to make is now lying quietly in his palm.

From the appearance, this bead component is a full circle larger than a table tennis ball, and its surface is glowing with silver-white metallic luster.

It looks light and light in the hand holding the won, but in fact this small thing is quite heavy.

Just such a one, the Korean won weighed it, and it weighed more than [-] grams, which was close to a catty.

This is mainly due to the fact that the various materials inside are metals with a relatively high density.

Now that the magnetic bearing's joint ball is manufactured, it is natural to test it.

This kind of parts is not processed by CNC machine tools, and the quality of hand-wound and assembled coils is not as good as that produced by machinery to a certain extent.

As for how to test, Won naturally has a way.

Before the whole magnetic bearing joint is produced, the external magnetic field controller is required for the testing of individual components.

This magnetic field control device was used in the manufacture of electric propulsion-free fluid engines a long time ago, and it was sealed in the storage room for a long time. He dragged it out two days ago and used it as a test tool for magnetic bearing joints.

The external magnetic field controller is a device that looks somewhat similar to a black and white TV, but is much larger than a black and white TV.

Its diameter reaches an astonishing [-] meters. It can generate a magnetic field in the hollow area inside, and control the strength and direction of the internal magnetic field through buttons.
