Hand rubbing nuclear fusion live in the wilderness

Chapter 130 Assembling the Generator

The silver-white bearing ball fell into the hands of Han Yuan, shining with a silver-white metallic luster.

Although the surface still looks rough, it is the trace left by the grinding wheel.

This has reached the limit of what the ball mill can grind.

After processing and grinding, it is necessary to replace other grinding materials.

Han Yuan carefully inspected each roller in his hand, using a vernier caliper made of copper-iron alloy to measure the diameter in all directions, and then picked out the non-compliant ones from the middle.

Of the six balls that were polished at one time by the ball mill, the diameter of two balls deviated from the others by more than 0.05 mm in the end, so they had to be picked out for later use.

Seeing this, the live broadcast room was surprised.

[Is this a waste of two? 】

[Are these two useless?Anchor, it looks quite round, doesn't it? 】

[Six out of two, this efficiency is quite low, our factory can produce tens of thousands of balls a day. 】

[This is already pretty good, okay?What equipment are you using, and what equipment is the streamer using? 】

[Give me the unwanted balls to play with as marbles. 】

[When I was young, I played with glass beads, and when I grew up, I played with grapes, ate peaches, and pinched watermelons. 】

While putting another batch of unpolished balls into the ball mill for processing, Han Yuan picked up the two balls that were picked out and put aside, saying:

"These two balls are not waste, but there is a deviation of more than 0.05 mm in diameter from the other four balls in the same batch."

"So they can't be placed in the same bearing, so they can only be picked out first."

"After all the balls are ground out, see if there are any that have the same diameter as these two, and then they can be reassembled."

The vitrified grinding wheel in the ball mill has been replaced several times, and the [-] balls have finally been preliminarily ground.

After jumping and choosing, finally, three sets of bearing balls with a diameter difference of less than 0.05 mm were barely combined.

Two groups of eight, one group of six.

As for the remaining eight balls, they are really useless for the time being, and the diameter deviation from the other balls is too large to be usable.

The abrasive in the ball mill is replaced with cowhide, and the balls are then polished.

Han Won took the assembled balls and began to manufacture the outer ring and inner ring according to the diameter.

Compared with the level of balls, the outer and inner rings of the bearing are much simpler.

After the inversion is completed, the lathe is used for grinding and processing. The two-axis lathe is matched with the corresponding turning tool and abrasive tool, and then the cowhide can be used for grinding and polishing.

Although it is far inferior to the bearings produced by modern industrialization, it is already the highest industrial level that can be produced by South Korean Won.

The bearing balls and inner and outer rings are manufactured, and all that remains is assembly.

Under the camera, Han Won held the ground and polished bearing in his hand and showed it to the audience.

The bearing balls polished by cowhide are very smooth and smooth.

In order to ensure the stability and durability of the bearing to the greatest extent, a set of bearings has eight balls.

In addition to this, Won also manufactures metal retainers and dust covers.

These two things also function to increase or decrease the service life of the bearing.

The retainer can fix the ball rolling in one place to avoid more collisions, and the dust cover is to prevent dust and impurities from entering the bearing.

Han Won explained while placing the roller in his hand into the outer ring of the bearing.

"The installation of the bearing is actually very simple."

"First put the balls into the bearing and put them together, and then press the inner ring in firmly."

As he said that, as soon as he exerted force with his hand, the inner circle was properly stuck into the outer circle.

Hang the inner ring with one hand, and exert force on the outer ring with the other hand, and the outer ring of the bearing and the balls inside will roll.

A fine humming sound mixed with the sound of metal collisions entered the live broadcast room.

【Fuck! 】

[Silky, really silky, just like Dove. 】

[Awesome, this is the real craftsman who makes high-precision bearings from scratch. 】

[Really awesome, it is estimated that more than [-]% of the countries in the world do not have the technology of anchoring. 】

[There are only a few countries that can manufacture high-end bearings, not to mention high-end ones. Of the more than 200 countries, [-] to [-] cannot produce bearings. 】

[One person is worth a country? 】

After seven or eight seconds passed, the bearing in his hand stopped rotating. This level of bearing is already comparable to the one made by Huaguo Seven in the 80s.

This is still in the absence of lubricating oil, lubricating oil is applied to reduce friction and the bearing can run longer.

The bearing stops rotating, and Won installs a retainer on the inner ball, and then puts some butter on it for lubrication.

No way, butter is also oil, and he doesn't have special bearing oil on hand, so he can only use it instead.

The bearing rolled smoothly, and a bright smile appeared on Han Yuan's face.

The most difficult hurdle of making a generator has been passed.

The rest of the parts are relatively easy to make.

The center rotor shaft is made of medium carbon chromium-iron-copper alloy.

The rotor and stator of the generator are directly cast with cast iron, and then turned on a two-axis lathe.

The melted copper is hydraulically drawn into copper wires by a wire drawing machine, and then passes through the pre-flowed holes in the stator in a specific direction to form a stable tangent, and can output current.

All parts such as casing, output wiring, brushes, rotary rectifier, frame, armature, etc. can be processed by reverse system or two-car lathe.

After half a month, Han Yuan finally got all the parts of the designed generator out.

The only difference from the modern small excitation generator is that the generator he made lacks the voltage regulator.

But this is something that there is currently no way around.

Because he can't make transistors now, and there is no substitute.

The consequence of missing the voltage regulator is also quite serious. Although it can generate electricity, the output voltage is unstable.

After all, the faster the rotor speed of the generator center, the higher the output voltage, and the slower the speed, the lower the output voltage.

The voltage is unstable and it is easy to burn out the electrical appliance.

The only remedy is to hope that the water flow rate of the dam can be controlled, and relatively speaking, it can be maintained at a stable flow rate.

This can slightly control the output voltage to a certain extent.

The parts of the generator are assembled, but they cannot be used immediately.

Also need something that can prove and draw current.

The simplest, of course, is the electric light.

Compared with other electrical appliances, the glass of the light bulb is easy to manufacture, and it is easier to see the effect.

Although he has not found tungsten ore, the filament can be replaced by another material.

That is bamboo charcoal silk.

This material is the best material that Edison discovered during the process of inventing the electric light bulb.

It is burnt in a closed high-temperature furnace and then processed to obtain carbonized bamboo filaments.
