"Director Zhou, we can't be so cheap on this guy!" Song Weize felt aggrieved as he walked. He is the director of the R&D room. Now, the R&D room has given out four quotas. Can they get four?
What should I do if there are not enough? Even if there are enough, it will only be four at most, right?
At that time, the people in the maintenance workshop swarmed out, and the people in their research and development room looked on helplessly? Then he, Old Song, had to be scolded half to death?
One general is incompetent and a thousand troops will be exhausted.
"If you are unable to complete the task of surveying, mapping and imitation, it will embarrass our entire factory." Zhou Xuejun said: "Didn't you hear the call just now? Someone is here to poach Qin Zhenhua. If we don't give him any benefits, if he leaves,
Tell me, how can you save your project?"
Qin Zhenhua, so popular? He should be notorious for this, right? He doesn't obey discipline at all!
"Especially, the Tank Research Institute is the most likely. You also know that after Lao Qin left, many people from the R&D room went to the Tank Research Institute." Zhou Xuejun said: "If they are still there, the people from the R&D room will
Technical strength is not enough to overcome such a difficulty."
Speaking of this incident, Zhou Xuejun felt very emotional. The accident at that time was really an accident. As for the issue of liability for the accident...
Forget it, it’s all over, why are you still thinking so much? First think about how to complete the project in front of you. Qin Zhenhua, can you find out the reason why their imitations have repeatedly failed?
As the deputy director of the factory, Zhou Xuejun still had a lot of things to do. It was already a huge honor to invite Qin Zhenhua. As a result, he got four more quotas. Anyway, it was the quota for the R&D room, so he finally invited Qin Zhenhua.
As for whether it can be cashed in in the future, it depends on the actual situation. When the time comes, get one for Qin Zhenhua, it will be considered worthy of him.
Now, let’s see if he has the ability to tackle this technical problem.
Unconsciously, Zhou Xuejun thought about the skills competition again. It was the first time he saw Qin Zhenhua's performance. At that time, he felt that this kid was very powerful and was definitely more capable than his father.
Now, it depends on Qin Zhenhua's performance.
Fortunately, with almost the same effort, Qin Zhenhua finished handling the matter at hand, handed the processed warhead and cartridge holder assembly to Luo Ronggen, and went to the R&D room.
Of course Qin Zhenhua was also interested. How could he be satisfied if he only mapped and copied a hydraulic torque converter? Now that he has come into contact with more things, of course he came here with great interest.
"It would be great if there were two M48 tanks." When Qin Zhenhua came in, Du Youwen was complaining: "If that's the case, let's just put everything inside into our outer shell, and I'm sure there will be no problem."
Anyway, it's just a surveying and mapping imitation, and it can't be mass-produced. Let's just take a shortcut. Otherwise, who knows where the problem lies?
"Our three boards and three poles are pretty good, aren't we? Driving a tank is not for enjoyment. I really don't understand the intention of the boss." Du Youwen's complaint is resonant. After all, everyone started mapping and imitating the kind of enthusiasm.
, now it has been suppressed by continuous failures, leaving only endless distress, which has turned into resistance to this project.
"Hey, are you all here basking in the sun?" Qin Zhenhua looked at the exhausted technicians with a smile on his face: "Where is Director Song?"
"Here it comes, here it comes." Director Song trotted all the way from the office, putting aside other worries first to see how Qin Zhenhua solved the problem. Did he have the ability?
"Tell me about the problem." Qin Zhenhua said.
"Xiao Du, please introduce me." Song Weize said.
So, with a look of reluctance, Du Youwen started to introduce. Every time it runs for a few minutes, the transmission will be damaged internally and stuck. Because the transmission is stuck, the front torque converter rotates crazily, only
This will cause the oil temperature of the torque converter to rise, and the energy of the powerful engine will become the internal energy of the torque converter. Over time, it is normal for it to burn out.
"So that's it." Qin Zhenhua said: "You don't know where to start with such a simple question? Use your brains more."
Qin Zhenhua's tone of voice was full of hatred. The technicians present looked at each other, especially Du Youwen, who felt very uncomfortable. Doesn't this mean that everyone is incompetent?
"So, do you know the reason?" Song Weize asked Qin Zhenhua happily, calling him over just to solve the problem.
"It goes without saying. Think about it. What's the reason for the gear burning?" Qin Zhenhua asked back: "Director Song, do you know?"
This question was quite rude, but Song Weize still endured the rudeness and answered seriously: "Generally speaking, the lubrication is not enough."
"That's right. You can find the problem yourself. The lubrication is not in place! Everyone, if there is not enough lubrication in your gear box, how can it work normally?"
"But, we obviously designed it according to the original parts, so how could there be a problem of insufficient lubrication?"
"Because you are not serious." Qin Zhenhua said with hatred: "You have this gearbox and the original gearbox. Take it apart and take a look."
Disassemble it? Do you know how troublesome it is to disassemble it once?
Du Youwen was very reluctant. He definitely didn't want to take it apart anymore. Moreover, he also had to take apart the original one, which was a lot of work.
"Why, no one did anything?" Qin Zhenhua looked at Song Weize: "Director Song, if I don't open it, how can I find mistakes for you?"
"Tear it apart, take it all apart." Song Weize said. It's broken anyway and can't be used. Let's take it apart and see why.
So, from the afternoon until the sun went down, the two gearboxes were disassembled. Everyone's hands were stained with oil and their faces were slightly dissatisfied.
It's taken apart, so what? Do you always like to play tricks like this?
"Our previous gearboxes were in the form of fixed shafts and relied on splash lubrication. Today's automatic gearboxes use planetary gears, sun gears, frames, and ring gears. These are the three elements of a single planetary gearbox. Because here
There are only two speed ratios, so there are only two sets of planetary gears." Qin Zhenhua gave directions outside.
We all know what you said, do you really think we don’t understand anything?
"So, you can see that compared with our previous fixed-shaft gearbox, its structure and connection relationship are complex, and there are many parts. It often requires the use of multi-layer sleeve shafts, and the internal oil passages are also very complicated. Now, look here."
Qin Zhenhua pointed his hand at the grooves on the disassembled original transmission case, and said to everyone: "See, these grooves are the oil passages of the transmission case. Look at your own imitations, although they are also pretending to make them.
The groove came out. When you were die-casting, did you leave any lubrication lines in it?"
What?
Everyone was surprised, and Du Youwen couldn't help but said: "How is this possible? Aren't these grooves used to reduce the mass of the transmission case?"
"Reducing quality?" Qin Zhenhua was speechless when faced with this idiotic question: "Didn't any of you look at the materials ordered in the data room of our factory?"
