Chapter 2007: High-speed rail bearings

This old Li is the real expert.
Of course Qin Guan also knows that for high-speed trains, the use of a special three-phase AC motor is not that difficult, and it can be done with the domestic technology of Han. However, the transmission system will not work. The wheel, the transmission system in the middle, is the most difficult place.
This is just like a car. Domestically-made cars can produce car shells and engines, but the most critical gearboxes are still purchased. Although they can produce it, they are all low-end.
Now, this old Li is singing the opposite tune here, blatantly speaking the opposite, so that the leader can't sit still, and he yells at Old Li, "Old Li, are you drinking too much? What nonsense?"
"Am I talking nonsense? Okay, just as I was talking nonsense, I want to see, the gear box, how do you plan to solve it." Lao Li spread his hands together.
"Old Comrade Li, it seems that you have a very thorough understanding of this issue, but here, we are not meant to be just jokes." Qin Guan said from the side.
Lao Li was so sarcastic. Although he was talking about China South Locomotive and North Locomotive, he also ridiculed Qin Guan. This was obviously a great leap forward.
Now that Qin Guan said this, Lao Li was embarrassed: "Mr Qin, I'm not talking about you."
When these words are said, it makes people feel that they can't go through their faces. This old Li can't speak clearly.
Qin Guan shook his head: "Old Comrade Li, I don’t care about other people’s criticisms at all, but if there is only ridicule, then we are not qualified as country builders. We are here not only to provide opinions, but also There must be a solution to the problem. If we want to build a country and build our high-speed railway, we will definitely encounter difficulties. Should we just bow our heads in front of these difficulties and then wait to speak coldly?"
When Qin Guan said this, Lao Li also felt that he couldn't live up to his face: "Mr Qin, I was wrong."
This old Li has no background, just a rib, what to say. At this meeting today, as soon as Qin Guan said that he would build a high-speed rail, he thought of the technical difficulties in it, and then looked at the north and south trains. When he expressed his attitude, he couldn't help but speak up. He could not be driven away because of his technical difficulties. Now that Qin Guan said this, he also felt that he should not be sarcastic. He saw it. Difficulty, but should I be sarcastic? Should I laugh at my comrades?
Lao Li wanted to slap himself, he was still so confused after living a half-life.
"No, no, you are not wrong. You are right. Bearings and transmission systems are the biggest difficulties that our high-speed rail faces. I originally wanted to leave it to our northern heavy truck factory to solve this problem."
The North Heavy Truck Factory has first-class processing equipment and the most professional technical personnel. With a new system, it can easily come up with the processing technology and leave it to Heriba to study. After all, high-speed bearings and gears, etc. , Will be used not only in high-speed rail, but also in many fields.
But now, Qin Guan has found a better candidate, Lao Li in front of him, can't play tricks.
"But now, I would like to ask, Mr. Li, are you willing to undertake this glorious and great mission? Study the most difficult transmission system on the high-speed rail?" Qin Guan asked Lao Li.
When Lao Li heard what Qin Guan said, the expression on his face was dreadful, and then he solemnly said: "I am very willing to serve, to develop the most advanced locomotive transmission system for our motherland, which is what I dream of. But, our current basic reserves It’s very poor. We lack advanced materials and advanced processing technology. Therefore, we face many problems."
To manufacture advanced bearings and high-speed gears is not just empty talk. It is just the simplest axle box, made of ductile iron, and requires a minimum impact strength of 12J at minus 50 degrees Celsius. As for the rolling bearings with the highest difficulty level, There are special inspections based on DINEN12080 standard, including ultrasonic inspection of inner and outer rings, which require the highest quality level class1.
Is there such material in China? Is there such processing technology? Once there is an idea, even if it is the material, I am afraid that it will not come out in China.
"As for materials, you can find them from various departments of our military system. In terms of processing technology, you can cooperate with the northern heavy truck factory. In short, what I want is maturity and absolutely no problems. Once a problem occurs, it will bring the train to the train. The most serious accident."
Qin Guan promised to solve these problems. Since the latest system was unlocked, there was nothing to do.
Qin Guan has already stated this, and Lao Li is naturally unambiguous. He said to Qin Guan: "It is a great honor. I will definitely fulfill my mission and get our own high-end bearings."
As a military representative, Major Yang has been watching here all the time. After all, military systems have a lot to do with civilians. Now they are studying high-speed railway technology and can also serve national defense when needed. Of course, Major Yang came here this time to bring everyone new news.
Now Qin Guan has deployed the high-speed railway project, and finally it is Major Yang's turn.
"Comrades, the construction of the motherland cannot be separated from the railways and our railway people. I am also proud of everyone. Our country's railway construction will certainly continue to develop and reach the world's advanced level." Yang The major first encouraged everyone, and then said: "At the same time, our army also has a need for the railway department."
In the past, the railway originally belonged to the army, but later it became a local. Now, Major Yang’s encouragement to the railway department is to encourage the old soldiers. Everyone applauded, so Major Yang paused. After a while, he continued: "Our army also needs the cooperation of the railway department. For example, we now want to launch missiles on the railway. I don't know if the railway department can provide us with this kind of opportunity."
On the railway, missiles are launched maneuvering, isn’t that a missile train? Qin Guan became excited at the words of Major Yang.
In the past, the military equipment construction was proposed by Qin Guan and developed. This time, it is really an exception. It was actually proposed by Major Yang on behalf of the military.
Qin Guan was overjoyed when he listened. Our army finally started to find its own shortcomings and continued to optimize its equipment. The missile train, a big killer, is really suitable for Han, even more than missile nuclear submarine more suitable.
