"Director Zhao, didn't the troops ask questions? You should quickly reply to the troops so that they can pick up the tanks tomorrow." Liu Jianzhi said to Zhao Guodong.
"Yeah, hurry up and get back to the troops. If it can't be repaired, the commander of the tank division will come and kick in my old Zhao's office door." Director Zhao had a helpless smile on his face: "Okay, everyone is off work.
Well, it’s not easy after a hard day’s work.”
"Yes, Director Zhao, please walk slowly." Liu Jianzhi said, turning to look around: "Well, everyone did a good job today. We are all tired. We will be here today and get off work."
In the factory, the master is the authority. When the apprentices heard what the master said, they all breathed a sigh of relief, and the day passed again!
The crowd dispersed, leaving only tanks one after another. The barrel of one of the tanks was still dirty inside, stained with gunpowder dust and yellow copper stains.
Everyone has forgotten it. Of course, some people have forgotten it deliberately, such as Liu Dajun, Huang Chuanchuan and the others. Who will wipe the barrel of the cannon? If he can escape for a day, it doesn't matter who he is.
The cafeteria is far away from the repair shop. When Wang Erzhu was panting and riding his bicycle, he just dropped the car and saw Qin Zhenhua riding his bicycle. At this time, the sky was completely dark, and the street lights cast his shadow.
It was stretched very long and looked a little faded.
"Brother Zhenhua, it's really dangerous today. You don't even know it. Just after you left, Director Zhao came. Master Liu took all the credit for repairing the tank." Wang Erzhu greeted Qin Zhenhua and shouted to him
he said.
"I know, don't yell, it won't be good for others to hear." Qin Zhenhua said to Wang Erzhu, as if his mind was not on this matter.
"I thought you came directly to the canteen. Come on, let's go in. You sit down and I'll get you some food." Wang Erzhu said.
Although the two have only been in contact for a few days, after all these things, Wang Erzhu has already recognized Qin Zhenhua as a good friend.
The food in the cafeteria is very simple, they are all the same, pork stewed with vermicelli, the plump pork belly, the real deal, a bowl can cost more than a dozen yuan. Outside, it is something you can only eat during the Chinese New Year, factory food
not bad.
Holding the steamed buns in one hand and chopsticks in the other, Qin Zhenhua started eating with big mouthfuls.
"Brother Zhenhua, you are so amazing today. You solved the problem in just a few clicks. What's going on?" Wang Erzhu asked Qin Zhenhua while eating. For him, today was also extremely surprising. Come on.
He stayed there for three days, just cleaning the barrel of the gun and hanging the tracks. He had no idea that Qin Zhenhua could do this.
"Well, you have to master the principles of tanks." Qin Zhenhua had nothing to hide from his brother, so he took the steamed buns and started making gestures.
"The power system of the 69 tank is mostly the same as the 59 tank, but there are also innovations. For example, its power has been enhanced and its torque has been increased. If it still matches the original transmission system, there will be overload.
, the lifespan cannot be guaranteed, so the strength must be increased.”
"However, the space is limited. To increase the strength, we will face the problem of insufficient space. Take the side reducer of the 69 tank as an example. The shell is the same size as that of the 59 tank. In this way, when designing, its straight teeth are
It's made into helical teeth." Qin Zhenhua said, and put the two steamed buns together to form the shape of two gears, straight teeth and helical teeth. He pinched them twice and they came out.
"This increases the contact area of the gear and increases its strength. However, it places higher requirements on processing, and the accuracy of assembly must also be high. There are marks on the gear, and the teeth need to be aligned."
Ordinary gears can be inserted directly, but this helical gear cannot be used. The teeth need to be aligned to ensure that the marked places on the gears on both sides are aligned. Otherwise, the gears will make that kind of sound because they do not mesh accurately.
But this fault is very hidden. There is no sound when the car is cold, because the gear oil inside is still viscous, and the gaps in contact with it will make a swishing sound when the car is warmed up, and the gear oil becomes thinner and the gaps become loose.
.
Every time they repaired it, the car got cold, so it was fine when I first drove it out, but after it warmed up, the problem reappeared.
"So that's it." Wang Erzhu suddenly realized: "Brother Zhenhua, how did you know? I don't think Master Liu understands it."
How did he know? Qin Zhenhua had already put down the steamed buns and touched his clothes unconsciously. In his inner pocket, there was a red-covered diary.
That is my father's relic. The reason why I was able to easily solve the problem today is what is recorded in this diary.
When the tank factory was first built, it was a complete copy of the Soviet model. Production only focused on production, and the design department only focused on design. However, as time went by, domestic factories also developed, and factories set up their own R&D institutions.
At least it should be able to improve something on a small scale.
The technical department responsible for research and development in the No. 1 Machine Factory is full of well-known capable people. For example, Qin Zhenhua’s father is a talent that the Tank Design Institute and the Armored Forces Academy want to poach. However, Qin Zhenhua’s father will not go anywhere.
Staying in the factory, listening to the roar of machines all day long, but...
"Oops, I forgot, no one has wiped the barrel of that 59 tank yet." At this moment, Wang Erzhu suddenly patted his head.
"Don't worry about that tank. Master Liu agreed to let others clean it anyway," Qin Zhenhua said.
Others? How is that possible? We two have been receiving special care from Master Liu! Anyway, the tank has been repaired. Maybe he will fall out tomorrow?
"Don't worry, we'll keep an eye on it tomorrow." Qin Zhenhua said. He just rode his bicycle around the factory. Although he didn't find what he was looking for, he saw another 69 tank from the army returning to the factory.
, the problem is exactly the same as today.
The tanks produced by this large-scale military factory, which is directly connected by the railway, are directly loaded on the trains for shipment. When Qin Zhenhua saw it, he had just stepped off the platform, so Master Liu had absolutely no idea that there were also 69 tanks.
Waiting for him!
He poured the last mouthful of vegetable soup into his mouth. He was really full. Qin Zhenhua wiped his mouth and was about to leave when he saw a man carrying an aluminum lunch box and walked to their table. He sat down and looked up.
, the other party's kind eyes were looking at him, full of the care of the elders, and Qin Zhenhua felt a warmth in his heart.
