"Sir, Qilu, the chief arrester of Pingxi City's criminal arrest gate has arrived and is waiting outside the gate ..."

There was a briefing from the bear outside the door, and Yan Liqiang lifted his head from the pile of paper on the table, and looked at the door, his heart moved. "Let him wait a moment, I'm done with the things at hand Let him in ... "

"Yes!" The bear rolled down and led away.

Yan Liqiang's gaze was again placed in the pile of paper on the table, and he muttered to himself, "Interesting ..."

At the top of the paper pile, there are several pictures. As Yan Liqiang, the two generations, he is very familiar with the things on those pictures-on the two pictures, one picture is a pattern of screws and nuts. The other is a bearing.

The screws and nuts on the picture look a bit rough. The spiral threads are not as fine as the ordinary screws that Yan Liqiang has seen in previous lives, and the openings of the wire teeth are a bit large. The square nut heads also look a little bit Strange, but these do not affect their identity. This is indeed a screw. The metal sample of this screw is placed in a box next to it. The sample is exactly the same as the figure.

Compared to this screw, Yan Liqiang is more interested in that bearing. The diameter of the entire bearing is about fifteen centimeters. The diameter of the inner ring is the size of a duck egg. There are four cylindrical rollers connected to the inner ring in the bearing. It looks like Silly and thick, but again, this is also a genuine bearing. The sample of this bearing is also placed in a box next to it. Yan Liqiang just watched it. It can be turned quickly with a hand and a small resistance. Such bearings, compared to the traditional sliding bearings that are now prevalent in the world, represent a huge progress across the ages.

These two things are not drawn by Yan Liqiang, but the latest invention of the craftsmen of the Manufacturing Bureau. Since the establishment of the Manufacturing Bureau, Yan Liqiang has paid great attention to the pioneering and inventive spirit of the craftsmen in the Manufacturing Bureau, as long as there is invention and craftsmanship. Breakthroughs all have awards. This award is not like making other good things like other artisan camps. It only rewards one hundred and twenty-two or dozens of silver. The reward in the manufacturing bureau is at least one hundred and twenty. At the beginning, the most was even tens of thousands of silver. It was in this atmosphere that the artisans in the manufacturing bureau were like chicken blood, full of energy, and made a lot of small inventions and process improvements. This screw and bearing is the latest thing made by several new artisans in the Manufacturing Bureau, and it is also the subject of public reward for Yan Liqiang in the Manufacturing Bureau.

Screws solve the problem of connection and fixation between metal parts and even non-metallic parts, while bearings solve the efficiency and durability of traditional sliding bearings used in carts produced in the manufacturing bureau. These two Yan Liqiang originally had an answer in his mind, but he didn't say it intentionally, but to see if the craftsmen of the Manufacturing Bureau could think about it and solve it. The final result was as expected by Yan Liqiang. The craftsmen have come up with a solution for a little longer, but no matter what, screws and bearings are still available.

The craftsman who made the screws was originally a jewelry craftsman in Pingxi City. The craftsmanship is good, and he specializes in exquisite things. I heard that the craftsmen on the manufacturing bureau side are highly treated, so he went to the manufacturing bureau. After some assessment, it was only last year. Progressive Manufacturing Bureau.

The invention of the bearing is also a bit funny, because when the water lighter was made before, the principle of the roller bearing has actually been applied to the water lighter, except that there is no bearing on the water lighter, but the flywheel and crankshaft. Four independent rollers are added in between, and the whole mechanism is completely connected with the water fire machine, which is part of the water fire machine mechanism.

This time, after hundreds of water-fired machines were manufactured in the manufacturing bureau, a craftsman finally thought that if the connecting part of the crankshaft and the flywheel on the water-fired machine was removed, the heavy flywheel and crankshaft would be removed, and the rotatable rollers and upper and lower parts would be removed. Turned into an independent component, can this component be used in other places as well, so the first roller bearing of Silver Continental was born.

Until now, although these two things were made out, the craftsmen over the manufacturing bureau have not named these two things.

Yan Liqiang likes these two things, but what makes Yan Liqiang happy and gratified is that he finally saw the vitality and creativity shown by the Manufacturing Bureau. With this ability, the Manufacturing Bureau is the manufacturing bureau in Yan Liqiang's mind.

——It can be named screw at this moment, inventing the craftsman's reward of 12,000!

——This object can be named bearing. The inventor craftsman rewarded 22 thousand yuan. This object can be used on the four-wheeled carriage first. On the latest water-fire machine, consider the connection between the flywheel and the crankshaft. Use this object instead. Screw and There is still room for improvement in both bearings. Hopefully the craftsmen in the bureau will continue to study and make persistent efforts!

——Seeing that the craftsmen in the bureau are more creative, they are also used to drawing with pencils.

Yan Liqiang took out his pen, brushed and wrote on the official paper reported by the Manufacturing Bureau. After seeing it, he put the official paper together and put it at the table. After taking a couple of sips of tea and resting for a while, he let it go. People called in the chief arrester of Pingxi City, who was waiting for the arrest.

Just a moment's effort, a man wearing a soap coat came into the hall. As soon as he came in, he looked at Yan Liqiang who was sitting behind the official case, and immediately gave a gift. See, See you, Lord! "

A thick beard, a Chinese character face, a dark face, and a strong physique. Coupled with the uniform that always captures the head, such a person casually stops on the street. It really has the timidity of those young people in the city. , This person is not strange to Yan Liqiang, but "acquaintance", but who knows, such a person is actually a Bailian person ...

Yan Liqiang sighed secretly, the serpent in his head had begun to move, but his face was more kind, and a smile appeared, "Sit down, don't be stubborn. Speaking of it, I and you are second I have met again. I remember the last time I met. It was still a few years ago that Mr. Sun came to Pingxi City and took Ye Tiancheng. I went outside the city and searched Ye Tiancheng's villa. ... "

Hearing Yan Liqiang's words, Han Ping's face, UU reading www.uukanshu. Com immediately showed just the right excitement and excitement. The **** just touched the chair and it bounced back. He bowed to Yan Liqiang again. I still remember! "

"Haha, I have a good memory. I remember that you were just a head catcher at that time. I didn't expect to have become a head catcher in recent years. You did a good job!"

"Humble work and hard work, thanks to the promotion of King Wang Jianbei ..."

"Do you know why I called you this time?"

"Slightly guess!"

"Haha, you are so real. Then why do I call you!"

"The grown-up called for a humble job, presumably because of the disappearance of Gongdaoshe practitioners!"

"Yes, you guessed it right!" Yan Liqiang's eyes narrowed slightly, his upper body leaned forward, and he stared at Han Ping's face seriously. Students and advanced samurai, in your opinion, who dares to take Xue Cao away, what has you been tracking for so long? "
