Because he was attracted by a giant waterwheel that was still under construction.
The giant waterwheel cannot directly cut wood into shape.
This requires the use of splicing wooden blocks into a circle, and the wheels are also made in this way.
The wooden blocks are spliced together using a mortise and tenon structure, then covered with iron sheets and fixed with rivets.
The spokes and eight-sided cylinders are embedded in the wheels when they are made.
It's the making of wheels.
At this time, the large waterwheel was made to be a little larger than the wheel.
Two large wheels are butted together and connected with a baffle in the middle, which is a large waterwheel.
Whoever can improve it will be rewarded with a reward of one yi.
But now, that's it!
especially.
The seemingly rapid current of the Zaohe River is only three meters per second, and the speed is only a pitiful 1.7 rpm.
And he wanted to reach the speed of the grinder, which was at least thirty revolutions per second.
This!
It must be consistent with the same coaxial rotation angular speed,
The large gear drives the small gear, and the speed of the small gear will increase.
The principle is that when a small gear drives a large gear, the speed of the large gear will decrease.
"Business about your business!"
Ying Cheng watched the construction of the waterwheel progress steadily.
After issuing the appointment document, we went to inspect other construction projects.
These were the only two things that concerned him. The rest, such as ink scraps and brushes, were in the hands of these 'strong generals', as long as they really had the skills.
After leaving the palace craftsman's workshop, Ying Cheng continued to inspect the next one.
From a distance, I could see black smoke billowing.
Even a mile away, you can feel the scorching heat coming from the front.
Gongshuqiu was one of the few great orders he appointed.
It can be said that he is the core figure in converting water potential energy into kinetic energy.
And the key is to convert the two.
Or a gear combination!
At the current industrial level, steel balls cannot be made to reduce friction losses.
Even the components can only be straight-axis gears and should be reduced as much as possible.
The large water tanker that is put into the Zao River can be made of wood.
But the rotating shaft, core gear, and gear set must be made of copper and iron.
This requires smelting a lot of copper-iron ore.
High temperatures are normal.
But wait until he walks over and takes a look.
Ying Cheng murmured secretly in his heart, "When I go back and look for it, I remember that there is a coal mine nearby!"
Even though Daqin's industry was extremely developed, it still used charcoal.
In the palace, the heating method is also a huge palace fireplace burning charcoal.
This is not that coal has not been discovered, but that it takes a long process of exploration from discovery to application and then to large-scale use.
Just like charcoal, it is full of wisdom from the ancestors.
Who would have thought that if wood is burned incompletely or pyrolyzed in isolation from air, the residue will turn into solid fuel charcoal.
Charcoal burns at more than twice the temperature of wood.
"Amazing, uncanny workmanship, so amazing!"
"Although there is a sawtooth runner, I didn't expect it to have such a precise effect. I didn't expect that the combination of gears one after another would have such a magical effect."
"Amazing."
"Especially the saw teeth on the side drive the flat gear to rotate. I am afraid only a god can think of it!"
"What's even more amazing is that the sizes of these things are different. When they spin like this, this, and this 'rotation' is also different. It's obviously so slow here, but here, it's incredibly fast."
"If this thing is modified and turned into a chariot, people only need to push it from the back. The front shaft is connected to a sharp weapon, and the gear combination is matched in the middle. Wouldn't it be... indestructible?"
"If this object is used to transform a catapult, how should it be transformed?"
As soon as he walked into the smelting site, Ying Cheng heard Gong Shuqiu sitting at a table muttering to himself.
He didn't even notice Ying Cheng's arrival, and was still disassembling and assembling his crudely made gear set, assembling and dismantling it again and again.
It seems that there are endless mysteries to explore.
Ying Cheng did not disturb Gong Shuqiu.
The application of mechanical gears is the core component of all power machines even in later generations.
It’s not surprising that the abandoned son of the Gongshu family could study it over and over again.
As for Gong Shuqiu, he had a little understanding of it. (It is purely a fabrication. There is no such person in history. To borrow, there is no Mohist government in this book.)
The Gongshu family has always been a craftsman family serving the Qin Dynasty, or more accurately, a military industry family.
For a long time, the Great Qin crossbows, heavy crossbows, crossbows, arrowheads, chariots, catapults and other ordnance have all been researched by the Gongshu family.
In Da Qin, it is more like a military equipment research base.
And this Gong Shuqiu, because of his drunkenness and mischief, leaked the manufacturing place of Da Qin's military equipment, which almost caused the ordnance base to be destroyed by assassins sent by Zhao State.
Afterwards, Gongshu Qiu had his big toes cut off and was sent to a place where bronze utensils were smelted.
It wasn't until Ying Cheng sat down that Gong Shuqiu noticed it and hurriedly knelt down to pay homage, "Caomin Gongshu Qiu pays homage to Dalu Ling."
Ying Cheng got straight to the point and asked without any politeness: "I have brought your wine official, and I have also brought the appointment documents of Dazaoling."
"Where is the gear I want?"
Ying Cheng glanced around for a long time, but did not see any copper gears in the smelting land.
Gong Shuqiu stood up consciously. He was once considered a big shot, and said calmly: "Your Highness, please move."
With that said, Gongshuqiu quickly led the way and kept chattering:
"Your Highness, I have been thinking hard all night and found that the middle of the gear is connected to the rotating shaft and drives the other gears to rotate, so that a balanced state can be achieved."
"At the same time, each serration must be evenly distributed, and the serrations between the two interconnected gears must fit perfectly."
"If the large gear is entirely cast by molten copper, it will be extremely heavy and waste too much molten copper."
"The common people took it upon themselves to make the decision and control part of it in the air, just like an axle, with a rotating shaft connecting it in the middle. This does not affect the rotation of the entire gear combination."
"In addition, the two gears cannot be too different. If the teeth are too large, they will not fit together."
Gongshu Chou said as he came to an open space.
Ying Cheng followed and his eyes suddenly opened up.
I saw that on the ground in front of me, there were densely packed mud fans one after another, piled neatly on the ground.
The largest one is a giant gear mold with a diameter of one foot.
The bulge between the center position and the edge position is the hollow place.
There is no problem with this.
What surprised him was that Gong lost his hatred and drew inferences from one example.
Surprisingly, the radii of the gear molds are different in size, and the saw teeth are almost the same and gradually decrease.
This can be called a genius, self-taught without a teacher.
At that time, you only need to pour molten copper into it, and it can be completed in one go.
"Not bad, not bad!" Ying Cheng cheered repeatedly, very pleased.
"Gongshuqiu thanks His Highness for his kindness in rebuilding his life, and I will definitely look up to you with His Majesty's head in mind."
Gongshu Qiu would not miss the chance to kneel down and worship him.
"Good job!"
Ying Cheng patted Gong Shuqiu on the shoulder and left.
He was originally here to provide visual guidance, but now that he has done so well, there is no need to stay any longer.
And next.
Ying Cheng inspected the remaining twelve workshops.
He provided visionary guidance on the problems that arose and basically moved forward in the direction he expected.
I just feel that I am one step closer to his grand ambition of domination.
After inspecting the construction of the river bank again, Ying Cheng raised his head and stared in the direction of Xianyang City with his eyes gradually getting darker.
"It's also time to see how my Dalu Mansion is doing."
"General Guo, gather a hundred soldiers and let's go back to Xianyang!"
