"The bearings of high-speed trains are related to the stability and safety of the train's operation. The technical requirements of this kind of bearing are very high. The faster the train's speed, the higher the bearing's speed. Now, the speed exceeds 140 per hour
The bearings of kilometers per hour are imported in China." Lao Wang continued to introduce: "The requirements for high-speed rail bearings are very high. After all, our trains need to operate on a large scale. The north is low temperature and cold, the south is humid and hot, and the high-speed rail is
There must be no accidents in bearings. Once an accident occurs, it may mean that there is an accident in the train and that the lives and property of the people will suffer huge losses."
Of course, Qin Zhenhua knew that freight trains do not need to be too high speed. High-speed trains mainly transport passengers. Once an accident occurs, it will lead to serious casualties. It can be said that it is possible for the relevant person in charge to go to jail.
"So, bearings have a great relationship with us, but bearings are just a component of high-speed trains after all. Even if they are purchased from high prices abroad, they do not account for much of the entire train, only two-thousandths, so, in addition to the heavy responsibility, it is a big deal.
In addition, with high investment in R&D and low returns, many related companies are unwilling to do this." Lao Wang said: "They have no responsibility."
Speaking of these, Lao Wang has no choice. Imported bearings will be choked by foreign countries at any time. However, if you study them yourself, you will have a large investment and low returns, and you may also take risks. Therefore, there are not many companies willing to conduct research.
We were worried about this matter, but as a result, Qin Zhenhua and the others came over and could ask for help from Qin Zhenhua.
One machine factory has the strength, technology and responsibility. Such a company is just right to help them.
"What technology is needed to study this kind of bearing?" Qin Zhenhua asked seriously.
"There are mainly two aspects. On the one hand, it is bearing steel. If you want to make high-performance bearings, you must have special steel. This kind of steel has always been monopolized by foreign countries. The other is the processing technology, which is not qualified.
The processing technology cannot meet the requirements." Lao Wang said, as if he was afraid that Qin Zhenhua would not take on this project, he continued: "In fact, when it comes to the most challenging bearing, it is not our high-speed rail bearing, but you
The bearings of the tank.”
When Qin Zhenhua heard him say this, he was a little surprised: "The bearings of our tank?"
Of course, there are a large number of bearings on the tank, but the requirements for the bearings of the tank do not seem to be high, and they will definitely not meet the demand for high-speed rail.
"The turret of your tank is rotating. Isn't it a big bearing between the turret and the body of the vehicle? This bearing is the most difficult to process. You must ensure high enough accuracy to ensure the hit rate of the tank gun.
So, since you can make such a very difficult bearing, it is no problem to make our high-speed rail bearings." Lao Wang said.
It is estimated that only Lao Wang regards the tank's turret race as a bearing, but this seems to be correct. Bearings are needed between moving and fixed parts, but the bearing situation is
It's so diverse.
Qin Zhenhua nodded: "This job, we will come next. We can help our brothers in R&D, which is also to challenge the world's highest level. Our machine factory likes to meet the challenges. By the way, I almost forgot.
There is another task to come here.”
As he said that, Qin Zhenhua took out his bidding letter: "I heard that we need some railway trains here, and our first-machine factory can help with production. This is our bidding letter."
"Railway train?" Old Wang received the tender letter handed over by Qin Zhenhua in surprise. He just glanced at it for a few seconds and nodded immediately: "We can sign this contract. We are at ease with the technology of the first machine factory.
We produce these trains, which will definitely be of the highest standard.”
"Old Wang, don't you need a meeting to study together? Can you make the decision?" Zhao Guodong was also a little surprised at this time. Of course, he knew that the other party urgently needed these things, but the problem was that this could never be Lao Wang.
It’s up to one person to decide. Lao Wang must have a meeting and study it before he can make a decision. Now, he made the decision in just one sentence, which is not in line with common sense.
Lao Wang heard Zhao Guodong's words and shook his head: "Of course we need to have a meeting, but I believe that no one will object to the meeting to discuss. The technical strength of the Yimai Factory is our first-class in China, even if it is Yimai.
The machine factory does not come to bid, but we still want to go to the first machine factory for help. The first machine factory can come to help us with production, so we can't get it. What is the bidding or meeting, it's just a process. Don't worry, you will definitely
Passed unanimously.”
Before coming, the two were worried about encountering some changes. Who would have thought that they would be decided like this. In this way, the first machine factory can drive at full capacity to produce these railway trains, especially the first machine factory.
There was originally a railway. After production, find a front of the car and can be directly dragged to the outlet and loaded and transported. This project is too simple for the first-machine factory, and the profit is not bad.
It is considered to have expanded a new business to the first machine factory.
In the future, as long as the product produced by a single machine factory has excellent quality and is recognized by users, it can be produced for a long time.
I originally thought it would be very complicated, but who would have thought that it would be completed so simply. At this time, Zhao Guodong and Qin Zhenhua both looked at each other and saw the joy in each other's eyes.
Lao Wang just briefly introduced this matter, and then returned to the main topic.
"Our high-speed rail bearing is the most critical. I hope that after receiving the task, the first machine factory can draw enough manpower and material resources to conduct research. Moreover, I am very sorry, our R&D funding is limited now, so I hope you can raise funds by yourself.
In research and development, as long as the products meet our requirements, we will give up foreign products and make every effort to purchase your products." Lao Wang said.
Qin Zhenhua and Zhao Guodong reacted to it. In terms of railway train orders, they gave some benefits to the first machine factory, which was actually to let the first machine factory develop bearings for them.
However, this was originally what Qin Zhenhua wanted to do, and there was nothing to refuse. He thought of what Lao Wang said when he came in just now, and then said: "Besides bearings, there seem to be other difficulties that need to be overcome, such as transmission
Box? Our machine factory can make advanced tank gearboxes by ourselves, and perhaps they can also make them for you."
