E factory, final assembly workshop.

As the assembly workshop, the environment is absolutely first-class, the huge assembly workshop windows are bright and clean, spotless, you have to change your shoes when you go in, and the ground is even cleaner, almost able to shine a human figure.

The assembly workshop, like the precision machining workshop, is the star unit of Plant E and the window unit. At this time, the second turboshaft C engine was being assembled.

The first turboshaft C engine has been assembled last night, and it has been delivered to the test workshop, followed by the factory test.

Before the completion of the final assembly of the aero engine, it is generally necessary to carry out a test run, some to carry out one test, and some models of engines to carry out two test runs.

If there is an abnormality in the parts, it needs to be analyzed, if there is no abnormality, it is necessary to assemble it again and test it again, and it can be delivered without abnormality.

With the completion of the final assembly of the first turboshaft C engine, the second engine has entered the assembly, but now it is stuck, and a group of technicians in the assembly workshop, including the technical director, are gathered in front of the engine being assembled, and many people are frowning.

Cao Wei, the technical director of the assembly workshop, was listening to the report of the technician in charge with a calm face.

"Director Cao, this is a strange thing, the driving gear and driven gear of the deceleration mechanism are not well meshed, we have checked for a long time, and we have thought about it for a long time, but we can't find the root cause."

Turboshaft engines generally have a deceleration mechanism, because the spindle speed of the engine is generally tens of thousands of revolutions per minute, while the rotor of the helicopter does not need such a high speed, and the rotor speed may be less than one-tenth of the engine spindle speed.

What should I do if the speed difference between the two is so big? Naturally, it is necessary to decelerate, the turboshaft engine has its own speed mechanism, generally through the guò gear deceleration, the speed is reduced partially, in addition, the helicopter also has its own reduction box, the speed can be further reduced, until the speed requirements of the rotor are reached.

Poor gear meshing of the deceleration mechanism!

As soon as he heard this, Cao Wei felt that the problem was more tricky, this is not an ordinary gear, it is a high-precision aero engine gear, which is more than a precision level higher than the general gear, and it is generally impossible to repair.

In addition, such gears are worth a lot of money, and these gears are tens of thousands of yuan each, not comparable to ordinary gears.

Cao Wei personally gently turned the pair of faulty gears, and looked at it carefully, and there was indeed a problem.

"Has the gear base been adjusted?" Cao Wei asked.

"Director Cao, it has been adjusted many times, but the effect is not great, and it cannot solve the problem." Comrade Technician in charge lowered his head and said.

Sure enough, the problem is very tricky, poor gear meshing is absolutely impossible, this problem must be solved, because this pair of gears not only has high speed, but also a lot of force, the power of the whole engine 1200 kilowatts, depends on this pair of gear output.

1200 kilowatts!

I don't know how many times the engine power of a sedan is so much power, such a large power means that the gears have to bear huge force when they work, no joke, Cao Wei's brows are twisted into a Sichuan shape.

Cao Wei belongs to the young Zhuang faction in the process technology system of E factory, Cao Wei, who has just turned 30 years old, can be described as high-spirited and ambitious, but he did not expect that after encountering the assembly of the turboshaft C engine, there were continuous problems all the way, and one was more difficult than the other, Cao Wei was extremely irritable during this period of time.

Doing it himself, Cao Wei took a group of technicians under his command to work for at least more than an hour, but he still had no clue, this pair of gears seemed to be on the same page as Cao Wei, but he didn't listen to Cao Wei's fiddling.

"Director Meng is here, Director Meng is here."

Meng Qiang, director of the assembly workshop, must have heard about this problem and came over in person, as the number one, there was a problem with the assembly of the turboshaft C engine, and Meng Qiang definitely couldn't sit still.

Seeing Cao Wei sweating profusely and his face stern, Meng Qiang knew that Cao Wei definitely didn't solve the problem, so Meng Qiang said: "Director Cao, since the problem is more tricky, immediately respond to the top and unite everyone's strength to solve it together." ”

Meng Qiang instructed, Cao Wei naturally carried it out, and regardless of the oil in his hand, he took out his mobile phone and dialed a few calls, and then said: "Director Meng, I will also report the situation to Mr. Liu, and Mr. Liu will come over in person." ”

"Mr. Liu has to come over in person." Meng Qiang was taken aback.

It seems that this problem is not small, and Mr. Liu can't sit still. Thinking so in his heart, Meng Qiang didn't dare to leave the scene, and waited quietly here.

Liu Qingshan came over quickly, and just a few minutes later, Liu Qingshan hurriedly came over, followed by several senior technicians.

"How's it going?"

Seeing that Mr. Liu asked, Cao Wei, the technical director, immediately introduced the situation, and Liu Qingshan also nodded solemnly, the question is more tricky!

Looking around, Liu Qingshan suddenly asked, "Why didn't you call our expert Li over?" ”

Expert Lee!

Who is the Lee expert!

Everybody, you look at me, I look at you. Meng Qiang and Cao Wei, as leaders, know who Expert Li is, Li Tianfeng entered the expert group and became the youngest expert in the history of Factory E.

Meng Qiang said: "Mr. Liu, I'll invite Expert Li to come over." After speaking, Meng Qiang was ready to call in person.

……

Besides, Li Tianfeng, he was in a good mood in the past two days, not only did he have the starting funds for starting a business in the future, but also there were not many things in the past two days.

In the office of the process improvement team, Li Tianfeng is guiding Zhang Can, He Baitao, Li Dawu three, recently, under the guidance of Li Tianfeng, the level of the three people has improved rapidly, some slightly simpler processes, basically do not need Li Tianfeng to know, the three can also be competent for improvement work.

At this time, the mobile phone rang, and when he heard that it was the ringtone of his mobile phone, Li Tianfeng took out his mobile phone and prepared to answer.

The three of them looked at the mobile phone in Li Tianfeng's hand together, and thought to themselves, Brother Li is different, this is the latest mobile phone, thousands of yuan each, Brother Li actually bought one, it's too bullish.

Seeing that the three of them looked at the mobile phones in their hands, all with envy and admiration, Li Tianfeng touched his chin, smiled proudly, and thought in his heart, his own mobile phone has become the idol of the three of them.

Pressing the answer button, Li Tianfeng said, "Hey, which one?" ”

This is an unfamiliar phone, the person on the other end of the phone is more enthusiastic, and very polite, "Is it Expert Li?" I'm Meng Qiang from the assembly workshop, and I'm looking for you to have a little technical matter. ”

Meng Qiang!

The sound of the mobile phone is a little loud, and the office is relatively quiet, Zhang Can, He Baitao, and Li Dawu can hear it more clearly, and the three of them all glanced at each other, and then nodded in unison, thinking in their hearts, Brother Li is a cow, Brother Li is mighty.

The three of them thought at the same time in their hearts, Meng Qiang is the workshop director of the assembly workshop, the first leader, the deputy director-level cadre, and the leading cadre of the precision machining center Peng Xuehai.

What did Meng Qiang say on the phone? Expert Li, calling Brother Li Expert Li, and using the honorific title of "you", the eyes of the three of them gradually became different, and they gradually had a little more admiration, Brother Li is really my idol.

Li Tianfeng also reacted quickly, the emotion was that Director Meng personally called him, for Meng Qiang, Li Tianfeng is no stranger, he has met several times, and the last time they met was at the last fault analysis meeting.

"Director Meng, you're polite, what are you looking for me?" Li Tianfeng was also more polite.

"Expert Li, is this ......" Meng Qiang said the situation on the phone, and then asked tentatively: "Expert Li, are you free now, can you come to our assembly workshop." ”

"No problem, Director Meng, I'll come over now." Li Tianfeng agreed more cheerfully.

"Okay, thank you, Expert Li." Meng Qiang was very happy.

After answering the phone, seeing Zhang Can, He Baitao, and Li Dawu looking at him blankly, with a look of admiration in their eyes, Li Tianfeng was happy for a while.

smiled and said, "What, you don't know me?" ”

Hearing this, the three of them reacted, and Zhang Can was the first to say: "Brother Li, you are bullish, Director Meng personally invited you over, what a face." ”

"Yes, yes, Brother Li, when did you become an expert!"

"Brother Li, you are our idol, I worship you so much."

Li Tianfeng smiled happily, and then walked out of the office and walked towards the assembly workshop, the assembly workshop is opposite the precision machining center, separated by a clean and spacious asphalt road, because it is a factory road, there are basically few cars on the wide asphalt road.

Li Tianfeng felt that he was so valued, and when he crossed the road, he saw Meng Qiang, the director of the assembly workshop, waiting for him at the door.

Walking forward quickly, Li Tianfeng said with a smile: "Director Meng, greet you at the door in person, it's too polite, too polite." ”

"Where, where, I'm going to trouble Expert Li this time."

While greeting each other, the two walked towards the assembly workshop, and before entering the assembly workshop, they changed into special clean slippers at the door.

The person responsible for distributing slippers at the door is a middle-aged woman, who belongs to the employees of the assembly workshop, Li Tianfeng remembers that when he came to the assembly workshop before, this person was very arrogant and basically ignored himself.

This middle-aged woman, don't look at it as just the lowest level of employees, is only responsible for the work of distributing slippers, but she is very snobbish, she has a cold face to ordinary personnel, and she is enthusiastic and even a little flattering to the leader.

Seeing Meng Qiang and Li Tianfeng talking enthusiastically and walking over side by side, the middle-aged woman couldn't believe her eyes, looked at them seriously, and after feeling that there was nothing wrong, she immediately changed to a flattering smile.

For such a person, Li Tianfeng directly ignored it, changed into slippers and walked inside.
