"You can try to find a few old carriages to install and test the bearings. If there is no problem with it for more than ten days of continuous use, we can start building a special bearing factory for large-scale production. In the future, no matter whether it is a two-wheeled four-wheeled carriage, it can be installed and used..."

"Go and find a carriage!" Before Chen Xu finished speaking, he jumped up and shouted.

So a few helpers in the shed threw down their tools and ran out to find the carriage.

"Horse rod, how many of these largest bearings have been made?" Chen Xu threw the large pulley in his hand to a carpenter next to him and stood up and asked.

"I only make ten of these, but there are many rings and steel balls. If the Marquis wants more, we can make ten more in a day or two..."

"Enough is enough, hurry up and arrange for the craftsmen to do more!"

"Okay, I'll make arrangements now!" Ma Gan ran away again with a bumpy look.

Soon several helpers pushed an old carriage to transport fodder. Under the command of the cart construction order, four carpenters and a group of helpers rushed over and turned the carriage over, waving their axes and hammers, quickly unloading the wheels and axles from the carriage.

"You two go and change the wheels!"

"You find a new axle to come..."

Following the instructions of the car-making order, the group of people became busy, but Chen Xu took a pulley and began to pinch his chin and ponder.

Chen Xu grew up in the countryside when he was a child. He played with two-wheeled wheels. He also saw that his father repaired wheels. However, the steel balls of the wheels were directly installed between the axle and the wheel. If the steel balls were broken, the wheels were removed, replaced with new steel balls, and then applied with butter and installed. However, the current situation is different from the wheels made in later generations, because all wheels are basically made of wood. Therefore, in order to facilitate replacement and maintenance, it is best to separate the bearings and the axle wheels. If the wheels are broken on the road, change the wheels, and change the bearings if the bearings are broken. This is the most convenient and fast. Just prepare a few more bearings on the long road.

In addition to the rapid rotation of bearings, there is another most obvious advantage that two wheels can form a huge speed difference, which is a natural differential. Cars with bearings can rotate in place. However, because the axle and wheels are fixed together, the two wheels will rotate together when turning, so they cannot turn in place. When turning, they can only turn big. Even if a two-wheeled carriage is running flexibly on the street, when turning, the wheels can only fall into the rut and rely on the pulling force of the cattle or horse to turn forcibly. In fact, the joint area between the axle and the body is quite wearable, and the wear of the wheels is also very obvious.

However, even if you use a bearing, the steel ball and the collar must be in a direct friction state. In addition, the steel is not good and the polishing is not smooth enough. If the service life of the bearing is to be extended, lubricating oil is a must.

But now no oil was found, even if he found oil, he could not synthesize butter from later generations...

There were jinglings in the shed, some were renovating old cars, and some were debugging new cars, but Chen Xu was as if he had been immobilized and pinched his chin at a bearing, turning a blind eye to the noise around him.

A long time later, Chen Xu suddenly put down his hand and called a manager from the Academy of Sciences and said, "Go and help me find some oil and graphite!"

"Hao, wait a moment, I'll go find it now!" The manager hurriedly left, and in less than ten minutes he hurried back, carrying a clay pot with a can of animal oil and salt on it. It was obvious that it was taken from the kitchen. He also followed a helper covered in dust and soil, using a pot of black graphite in a pottery basin.

"Mr. Marquis, bring them all. Do you see if they are enough?" the manager asked carefully.

"Enough is enough, find another milling trough to help me grind the graphite into the finest powder!"

Under the arrangement of the manager, two more assistants soon carried over an iron grinding trough, selected some clean graphite blocks and threw them into the grinding trough to start grinding.

The grinding trough was very common in rural areas before, and it was a must-have item in the pharmacy shop like a knife and iron mortar. Chen Xu played a lot when he was a child, and he also helped crush the medicinal materials in his second grandfather's pharmacy.

There is no lubricating oil at the moment. In fact, many people should know that the pencil core powder has a good lubricating effect. For example, the door lock is not easy to close, and it is very refreshing to apply the pencil on the keyhole and lock tongue to close the door. This is a very common life knowledge. The main component of the pencil core is graphite. Graphite is currently a factory in which crucibles made of steel, iron, and glass are used in large quantities. Graphite is also a necessary writing material for Chen Xu in daily life, but he has never been able to make pencils.

Since the pencil core can have a good lubrication effect, natural graphite powder is certainly OK, but the graphite dry powder will definitely be scattered easily. Chen Xu thinks that it can be added to blend it with a little lard butter. There is definitely no big problem when using it as butter for the time being. If possible, maybe you can add a little paraffin. This can be done after going back and letting people from the Academy of Sciences experiment.

Anyway, the development of precision industry in this primitive agricultural civilization is a very fussy thing.

Moreover, without scientists who are proficient in industrial design, all the things commonly used in life in later generations cannot be easily designed and manufactured. It is entirely up to Chen Xu to explain theories in detail and draw drawings, and then let the craftsmen figure it out and experiment it. Chen Xu knew nothing about many things, but he had seen it.

He has also seen cars, planes, trains and ships.

But I guess this life may not be enough to do it.

As for computers, mobile phones, cameras, you will definitely not be able to do it in your life.

Chen Xu stayed in the factory for a morning, personally watched and rode the carriage after installing the axle, watched the steering test of the four-wheeled carriage, and put forward his own ideas and rectification suggestions for some places. Later, he drew new bearing design drawings for Ma Rod and Gongshusheng, redesigned the steel ball specifications for the carriage bearings, and drew a schematic diagram of the spiral groove for the two to try to make a hot stamping spiral lathe to see if steel bars that are heated to a semi-melt state can be made with steel balls with more consistent specifications, and used spiral grooves to make the steel balls more rounded, so that when a large number of bearings are needed, there is no need to measure the size of the steel balls one by one with calipers.

Once the steel ball bearings enter the practical stage, the entire Daqin demand for bearings will instantly reach a terrifying number. There are tens of thousands of carriages in Xianyang alone. The carriages that ordinary carriages are better, especially trucks have more urgent demands for bearings. Once people know the benefits of bearings, they may become crazy. Everyone wants to transform their carriages into new bearing devices.

Therefore, thinking of this effect, Chen Xu reminded Gongshusheng and Magan to prepare a special bearing processing factory as soon as possible to speed up the design and manufacturing of bearings for carriages, and also found two carpenters from Qinghe Town, Stick and Donkey, and asked them to try to make a foot-type grinding and polishing machine based on the principle of the foot-type rolling machine to speed up the polishing and polishing of the bearing ring.

If you really want to promote Daqin to the road of industrial development, all equipment must slowly move towards the machine. No matter what kind of machinery and equipment appears, only when there are more machines and equipment, all kinds of work will be more labor-saving, and will also drive more people to change their thinking methods, constantly learn and understand the working principles of these machines, and then participate in it to improve and improve. As the School of Engineering and the Academy of Sciences slowly apply various scientific theories to life and production, we can slowly go faster and faster on the road of industrial development.

The industrial development of a country cannot be promoted by one person or two.

Especially in such a primitive farming era, it requires a huge scientific and technological community as the basis.

After lunch at the factory employee canteen and Magan Gongshusheng, one person, Chen Xu went to inspect the newly built glass factory, and then went to the cement factory built several miles away to see it, encouraging Zhang Wen and all the craftsmen in the cement factory to help him and prepare to return to the city.

But halfway through the way, I felt it was still early, so I changed the route and went to the manor that Li Xin gave him.

Li Xin's manor covers an area of ​​ten hectares, with several farmers responsible for farming, and a large yard covering an area of ​​more than 30 acres.

Chen Xu asked the housekeeper to take over the yard to clean up and arranged some servants and guards to take care of them, and was named Nanshan Villa.

The inner courtyard of Nanshan Villa was divided into two parts. Several houses were renovated and renovated and converted into a drug laboratory. Then Zheng Boqiao and his two apprentices were taken from the factory and arranged to secretly study the Five Poisons Shuhun Water and some other drugs. Xu Fu sometimes came to do experiments together.

The other part is the firearms research room. Two dumb slaves moved from the Academy of Sciences to continue making gunpowder. At the same time, they secretly recruited several craftsmen who were proficient in casting and mechanism to create more firearms, hand guns, grenades and other firearms, and even developed artillery based on fireworks.
