Take the warehouse back to the end of the Ming Dynasty

Chapter 286 Roller Bearings
When the steam locomotive reached the end of the railway, the steward controlled the steam locomotive and returned to the cabin.

Zhao Wen looked at the steam locomotive that had been put back, and said with a smile to the steward who was controlling the steam locomotive: "You guys did a good job with the steam locomotive, it's a great achievement for you."

The steward replied with a smile on his face: "My lord, this is what we should do. We are very grateful to you when you brought us to Xuanzhen. Without you, we would not be where we are today. We are just doing what we can now. matter."

"That's what I said, but what counts is what counts. In the future, you should do your best and work hard." Zhao Wen patted the manager on the shoulder and said earnestly.

"That's for sure." The steward said firmly.

Zhao Wen nodded, and then looked at Song Yingxing, "Come to my study tonight, this steam locomotive can still be improved a bit, I haven't told you the details of this steam locomotive before.

I didn't want to say it at first, after all, this steam locomotive is really difficult, but now I see that you can independently manufacture a steam locomotive, which proves that you are capable, so I think you should let the system Learn about steam locomotives. "

A smile appeared on Song Yingxing's face, "My lord, I will definitely go to my lord tonight."

For Zhao Wen, Song Yingxing admired and respected him. What he admired was that Zhao Wen could always come up with some new ideas that he had never thought of or seen before.

And this new idea is still a very good and practical new idea. These new ideas sometimes give Song Yingxing a sense of enlightenment, and they are very helpful to Song Yingxing's "Heavenly Creation".

Respect is because Zhao Wen does not treat the people like other officials, who treat the people as dispensable and animal-like characters. Zhao Wen is always very solemn in dealing with the people. To a certain extent, Zhao Wen's attitude towards the common people is like treating his own brothers.

After looking at the steam locomotive, Zhao Wen wandered around the ironworks and checked various things in the ironworks.

Today's ironworks are directly managed by Sun Yuanhua, and the smelting work in the ironworks is under the responsibility of Sun Yuanhua. Everything is going very smoothly, and the output of steel has also increased significantly.

According to this momentum, I am afraid that it will not be long before the cities of Xuan Town can be connected by railway.

Zhao Wen returned to the General Military Mansion after inspecting the ironworks a few times.

By this time, the sky was gradually getting dark.

Zhao Wen walked on the way back, looking at the extraordinarily bright night sky in this era, he was filled with emotion for a moment.

Back then, when he first came to the Ming Dynasty, Zhao Wen was just a small frontier soldier struggling on the verge of life and death. In five or six years, he had not only become the general soldier of Xuanzhen Town, but also made a steam engine.

Looking at the bright night sky, Zhao Wen thought to himself: "The steam engine has been manufactured, and the next step is to get the real steam locomotive out.

After the real steam locomotive is produced, the real steam ship will be produced. By then, I will go to hell with all the shitty empires on which the sun never sets. "

A few quarters of an hour later, Zhao Wen returned to the General Military Mansion.

At this time, dinner was ready, and Zhao Wen sat in the dining room with Hai Lanzhu and Li Xiaoying to eat dinner.

Li Xiaoying looked at Zhao Wen who was devouring, and couldn't help but said: "Eat slowly, you are now the commander-in-chief of a town, be gentle, which commander-in-chief have you ever seen eat like you?"

Zhao Wen swallowed the food in his mouth, took another sip of tea, and said disapprovingly: "Whatever, as long as you are full, why do you care about how you eat?
Besides, after traveling on the road for such a long time, I haven't had a good meal, and I must make up for it today. "

"Yes, Xiaoying is right. No matter how hungry you are, you should eat slowly. If you eat like this, what if you choke?" Hai Lanzhu put down the chopsticks in her hand and looked at it with concern. With Zhao Wen.

Zhao Wen chuckled and said, "Is it possible that you are still expecting me to choke? Let me tell you, on the battlefield, sometimes when you don't have time to eat, you just randomly dig a little fried noodles into the cloth bag that contains fried noodles, and then you can eat some fried noodles. Swallow with cold water.

Let me tell you, it’s not for humans.It's better to eat like this on the ground, but if you sit on a horse, you will choke after a few bites.

After eating fried noodles in cold water for so long, I have long been used to it, and now it is impossible for these meals to choke me. "

As Zhao Wen said, he pulled a few chopsticks of rice into his mouth for the first time, and swallowed the pickles on the table.

Li Xiaoying looked at the pickles that Zhao Wen swallowed, and couldn't help but said: "You said you are the general of the town, why do you like pickles so much?

What's so good about this pickle?When someone becomes a high-ranking official, he doesn't dare to say that he has a lot of fish and meat, but he doesn't know how to eat pickles all the time.

Since I've known you, you've eaten pickles for almost every meal.You are a person who leads soldiers to fight, you can't just eat pickles. "

While talking, Li Xiaoying picked up a small bowl, scooped a bowl of soup from the black-bone chicken soup on the table for Zhao Wen, and put it in front of Zhao Wen.

Zhao Wen hastily put the chicken soup back in front of Li Xiaoying, and said to Li Xiaoying, "This is black-bone chicken soup specially made for your miscarriage, drink it quickly."

"I can't finish such a big bowl of chicken soup, please help me." Li Xiaoying pushed the chicken soup in front of Zhao Wen again.

Zhao Wen looked at Li Xiaoying with a stubborn face, unable to resist her, he drank the chicken soup helplessly.

Zhao Wen wiped his mouth, put down the bowls and chopsticks in his hands, let out a long breath, and his face showed a look of nostalgia, "Why do I like to eat pickles so much? It's because when I was young, my family was poor and couldn't afford meat. Every meal can only eat pickles pickled by my mother.

Because Chinese cabbage is cheap, I buy a lot of it, and then pickle it into pickles, which can be eaten for a long time.

But who knew, by mistake, I actually came here, and I will never see my mother again. "

When Zhao Wen thought of his parents, he was overwhelmed with emotion for a moment, and felt an indescribable pain in his heart.

I'm afraid at this time, they all feel that they are dead.

Zhao Wen really couldn't imagine what would happen to his parents after they knew he was missing.

Zhao Wen picked up a piece of pickles, put them in front of his eyes, and said with a lonely face: "If there is no accident, I am afraid that I will never eat pickles made by my mother again in this life. She doesn't know that I already have them." child.

I don't know how happy she would be if she knew that I already had a child.And my dad, I guess he will jump up happily.Unfortunately, none of this will happen. "

Zhao Wen ate the pickle and chewed it carefully.Zhao Wen frowned slightly, because the taste of this pickle was not the one he was familiar with.

Until now, Zhao Wen can't forget the appearance of his parents.

Zhao Wen's family is in the countryside, just like many parents born in the [-]s and [-]s in rural areas, his parents are also the kind of farmers who are so ordinary that they can't be more ordinary.

Except for rain and snow, they will work at sunrise and rest at sunset, bending over in the fields every day, wearing straw hats, and cultivating crops.

Zhao Wen still clearly remembers that when he first stepped on the long-distance bus to the university, his father took out stacks of neat change from his pocket with callused hands and handed him the sentence "child , Poor family rich road, you take this money to buy something to eat on the road.”

Zhao Wen put down his chopsticks and looked up at the roof, forcing the tears that were about to fall back to his eyes again.

Seeing Zhao Wen like this, Li Xiaoying stood up, walked behind Zhao Wen, and gently kneaded Zhao Wen's shoulders.

Hearing Zhao Wen's voice, Hai Lanzhu thought that Zhao Wen's parents had passed away, so she comforted her and said, "Birth, old age, sickness and death are things that people have to go through in their life. It's better to take these things lightly."

Zhao Wen twitched his nose, looked at Hai Lanzhu, frowned and said, "My parents are still alive."

Hai Lanzhu stood there in embarrassment. After a while, Hai Lanzhu said, "Your parents are still alive? Then why didn't you take your parents over?"

Zhao Wen let out a long breath, and said helplessly: "I can't make it through, it's a distance of hundreds of years, I really can't make it through. That's all right, you can eat by yourself, I still have some things to do."

Zhao Wen gently took Li Xiaoying's hand off his shoulder, and then walked outside.

Li Xiaoying and Hai Lanzhu looked at Zhao Wen's leaving figure and didn't know what to say for a while.

"What does he mean by the distance of hundreds of years? Do you know?" Hai Lanzhu looked at Li Xiaoying and asked.

Li Xiaoying shook her head, "I don't know what that means either."

"But didn't you know him a long time ago? How come you don't know his life experience?" Hai Lanzhu asked unwillingly.

Li Xiaoying pointed to the sky and said: "How would I know, since the day I met him, he never told me about his life experience.

As for the distance of hundreds of years just now, I think he should be talking about the distance from here to the sky. "

Hai Lanzhu opened her mouth wide and looked at Li Xiaoying in surprise, "Heaven? Is this true? Could it be that the rumors in the army are true? He really came from the sky?"

"Who knows." Li Xiaoying spread her arms and said mysteriously.

After Zhao Wen walked out of the dining room, he adjusted his mentality and went directly to the study.

When Zhao Wen came to the study, Song Yingxing and Sun Yuanhua had already been waiting outside the study for a long time.

Looking at the two of them, Zhao Wen couldn't help teasing and said, "You guys came quite early."

"We've just arrived, so we haven't waited long." Song Yingxing replied.

Zhao Wen smiled, and then said to the two of them, "If that's the case, you should come in first."

Zhao Wen pushed open the door of the study and brought the two of them in.

Zhao Wen fetched two chairs for the two, and then sat behind the desk.

Sun Yuanhua and Song Yingxing were not polite, and sat directly on the chairs.

As soon as he sat down, Song Yingxing couldn't wait to ask: "My lord, today you said that this steam locomotive can be improved. I want to know how your lord can improve it?"

Zhao Wen said with a smile: "This matter is difficult to say, and it is not difficult to say that it is not difficult. Today's steam locomotives are so slow, what do you think is the biggest problem now?"

Sun Yuanhua and Song Yingxing looked at each other with confused faces.

"My lord, please clarify." Sun Yuanhua asked respectfully.

Zhao Wen took out a piece of rice paper and charcoal from the side, and quickly drew a sketch of today's steam locomotive on it.

Zhao Wen put down the charcoal pencil in his hand, pointed to the wheels of the steam locomotive in the sketch, and said, "The biggest problem with this steam locomotive is that the wheels and axles are directly connected.

When I looked at it today, I found this problem.The wheels and axles are directly connected together. In this way, there will be intense friction between the two. If the friction is large, the speed will naturally not increase. "

"But my lord, from ancient times to the present, no matter what kind of vehicle, the wheels and axles are directly connected together." Sun Yuanhua frowned.

"Yes, it has been connected like this from ancient times to the present. Could it be that there are other ways besides this method?" Song Yingxing also looked at Zhao Wen curiously.

Zhao Wen smiled lightly, then took out another piece of rice paper and started drawing on it.

If there are people from later generations present, they will definitely recognize that the thing Zhao Wen painted is a bearing.

The drawing drawn by Zhao Wen is the rolling bearing of later generations, but the bearing is not a ball but a cylinder, so it is also called a rolling bearing.

The reason why Zhao Wen took out this kind of bearing is because things like steam locomotives are very heavy, and ball bearings may not be able to bear such a heavy weight.

However, roller bearings can withstand it, so Zhao Wen decided to use roller bearings at the junction of steam locomotive wheels and axles.

In addition to the roller bearing, Zhao Wen also drew a drawing of a ball bearing.

Although steam locomotives are not available now, lathes such as drilling machines and boring machines can be used.

Since Zhao Wen made the steam engine, he also made simple drilling machines and boring machines, but because Zhao Wen didn't use drilling machines and boring machines at that time, he didn't think of getting bearings.

Zhao Wen put the two bearing sketches in front of Song Yingxing and Sun Yuanhua, pointed to the roller bearing and said to them: "This thing is called a roller bearing, and it can solve the problem I just mentioned very well."

Song Yingxing looked at the roller bearing on the drawing, and frowned tightly, "My lord, are you sure this thing can solve the problem just now? I think the thing you drew is a bit too simple."

"Yeah, just such a small gadget can solve a problem that has existed for thousands of years? I really can't believe it." Sun Yuanhua's face was full of disbelief.

Zhao Wen looked at the two of them like this, and said with a light smile: "Don't look at these two things as simple, with the current level of our Xuanzhen, I feel that the standards produced are not standard enough.

Especially for this ball bearing, it looks like a large ring with a small ring, and there are small balls between the rings. Let me tell you, even these small balls are probably enough to make it. "

"Isn't it just a few small iron beads? What's so difficult about it?" Song Yingxing still looked disbelieving.

Zhao Wen looked at the stubborn Song Yingxing and said with a smile, "Since you don't believe it, then wait until it's made."
