Yingcheng quickly put what had just happened behind him.

Because he was attracted by a huge waterwheel that was still under construction.

Giant waterwheels can't cut wood directly.

And this requires the use of wooden blocks to splic, spliced into a circle, and the wheels are also made.

The wooden blocks are spliced with a mortise and tenon structure, and then wrapped with iron sheets on the outside and fixed with rivets.

And the spokes, the eight-edged cylinders, are embedded in them when making the wheels.

It's the making of wheels.

At this time, the production of a large waterwheel is a little larger than a wheel.

Two large wheels are docked together, and the middle is connected by a baffle, which is a large water wheel.

Whoever can improve, he can be rewarded with a pen.

But for now, that's all!

Especially.

It seems that the turbulent water flow of the soap river is only three meters per second, and the speed is only a pitiful 1.7 revolutions per second.

And he wanted to reach the speed of the grinder, at least thirty revolutions per second.

And this!

It is necessary to conform to the same coaxial rotation angular velocity,

The big gear drives the small pinion, and the speed of the pinion increases,

The principle that the pinion drives the big gear, and the speed of the big gear decreases.

"Busy with you!"

Yingcheng watched the steady progress of the construction of the big waterwheel.

The appointment document will be issued, and other construction projects will be examined.

There are only these two that he cares about, and the rest are like ink dregs, brushes, in the hands of these 'fierce generals', as long as they really have hands.

Leaving the palace craftsman's room, Yingcheng continued to inspect the next one.

In the distance, I saw black smoke billowing out.

A mile away, you could feel the scorching heat coming from ahead.

The public defeat was one of the few major orders he appointed.

It can be said that he is the central figure who converts water potential energy into kinetic energy.

And the key to converting the two.

Or a gear combination!

At the current industrial level, steel balls cannot be made to reduce friction loss.

Even if it is a component, it can only be a straight shaft gear, which is minimized.

The large waterwheel that was put into the soap river could be wooden.

But the rotating shaft, the core big gear, the gear set, must be made of copper and iron.

This requires smelting a very large amount of copper and iron ore.

High temperatures are normal.

But wait until he walks over to take a look.

Yingcheng murmured secretly in his heart, "When I go back and look for it, I remember that there is a coal mine around here!" ”

Even though Daqin's industry is extremely developed, charcoal is used.

In the Imperial Palace, the heating method is also a huge palace fireplace burning charcoal.

It's not that coal hasn't been discovered, but that everything needs to be discovered and applied to large-scale use, and it takes a long time to explore.

Just like charcoal, it is full of the wisdom of our ancestors.

Who would have thought that if the wood is not completely burned or pyrolyzed in the condition of being isolated from the air, what remains will turn into solid fuel charcoal.

And charcoal burns more than twice as hot as wood.

"Amazing, amazing, amazing!"

"Although the sawtooth runner has it, I didn't expect it to have such a precise effect, and I didn't expect that the combination of these gears one after another would have such a miraculous effect."

"It's amazing."

"Especially the serrations on this side, which drive the flat gears to rotate, I'm afraid only the gods can think of it!"

"What's even more amazing is that this thing is different in size, turning this, this, and this 'turning' is not the same, obviously it's so slow here, but here, it's unbelievably fast."

"If this thing is transformed into a chariot, people only need to push it in the back, and the axle in front is connected to a sharp weapon, and the middle is matched with this gear combination, wouldn't that be ...... Invincible? ”

"If you use this thing to transform a catapult, how will you transform it?"

As soon as he walked into the smelting place, Yingcheng heard Gong Yiqiu sitting at a table muttering to himself.

didn't even notice Yingcheng's arrival, and he was still dismantling and reassembling his shoddy gear set over and over again.

It's as if there's an endless amount of magic.

Yingcheng did not disturb the public and lost the revenge.

The application of mechanical gears was the core component of all power machines, even in later generations.

It is not surprising that the abandoned son of this public loss family can be studied so repeatedly.

As for this public revenge, he understood it a little clearly. (It's purely apocryphal, there is no such person in history, borrow it, there is no Mojia organ city in this book)

The Gongyi family has always been a craftsman family serving Daqin, more precisely, a military family.

For a long time, various ordnance such as Great Qin crossbow arrows, heavy ballista carts, crossbow arrows, arrowheads, chariots, catapults, etc., were studied by the Gong Yi family.

In Daqin, it is more like a military equipment research base.

And this public revenge, because of greed for alcohol, leaked the place where the military equipment was manufactured, and almost caused the ordnance base to be killed by the assassins sent by the Zhao State.

Afterwards, the public lost his thumbs and was sent to the place where the bronze utensils were smelted.

It wasn't until Yingcheng sat down that the public lost the revenge that he realized it, and hurriedly knelt down to meet him, "The grass people are losing the revenge and meeting the Great Law Order." ”

Yingcheng got straight to the point, and asked politely: "Your wine official has brought it, and the appointment document of the Great Decree has also been brought." ”

"Where's the gear that the officer wants?"

Yingcheng's gaze swept for a long time, but he didn't see any copper gears in the smelting place.

Gong Defeat got up consciously, he was once a big man, and said with a very calm attitude: "Please move, Your Highness." ”

As he spoke, Gong Defeat quickly led the way in front, and chattered:

"Your Highness, the grass people pondered all night, and found that the middle of this gear is connected to the rotating shaft and drives the other gears to rotate in order to achieve a state of balance."

"At the same time, each tooth has to be evenly distributed, and the teeth between the two interconnected gears have to be very well matched."

"If the big gear is all cast from molten copper, the weight is extremely heavy, not to mention that too much molten copper is wasted."

"The grass people took matters into their own hands and emptied part of the air, like an axle, and the middle was connected by a rotating shaft, which did not affect the rotation of the entire gear combination."

"In addition, the two gears can't be too far apart, and the serrations won't fit together if they're too big."

As he spoke, he had already come to a clearing.

Yingcheng followed, and suddenly his eyes widened.

I saw that on the ground in front of me, there were dense mud models one after another, neatly piled on the ground.

The largest is a giant gear mold with a diameter of one zhang.

The bulge between the center of the circle and the edge is the hollow place.

There's nothing wrong with that.

And what surprised him was that the public lost and the revenge drew inferences.

The radius of the gear mold is different, and the serrations are almost the same and gradually decrease.

This is a genius, self-taught.

At that time, you only need to pour copper liquid into it, and it can be completed in one go.

"Not bad, not bad!" Yingcheng applauded again and again, and was very pleased.

"The public loses the revenge and thanks His Highness for the grace of recreation, and he must look forward to His Highness."

The public loses the revenge, and he does not let go of the slightest opportunity to kneel and bow.

"Good job!"

Yingcheng patted Gong's shoulder and left.

Originally, he was here to guide the vision, but now that this is done very well, there is naturally no need to continue to stay.

And next.

Yingcheng inspected the remaining twelve workshops.

The problems that arise in it are guided by vision, and they are basically moving forward in the direction he expected.

I only feel that he is one step closer to his grand ambition.

After inspecting the construction of the riverbank again, Yingcheng raised his head and stared at the direction of Xianyang City.

"It's also time to see how my Dajufu is."

"General Guo, order a hundred soldiers, let's go back to Xianyang!"
