Chapter 0006: Conversations in the Cafeteria

Director Zhao, hasn't the military already inquired? Please respond to the military promptly so that they can come to pick up the tanks tomorrow

The last spoonful of soup was consumed, leaving him truly satisfied. Qin Zhenhua wiped his mouth and was about to leave when he noticed a person approaching their table, carrying an aluminum lunchbox. As the individual sat down and looked up, Qin Zhenhua was met with a pair of kind eyes filled with the concern of an elder, which filled his heart with warmth.

However, space is limited, and increasing strength faces the issue of insufficient space. Take the side reducer of the Type 69 tank as an example; its casing is the same size as that of the Type 59 tank. Therefore, during the design phase, its straight teeth were made into helical teeth. Qin Zhenhua said this while aligning two steamed buns to form the shape of two gears, demonstrating the difference between straight teeth and helical teeth with a slight pinch.

"Brother Zhenhua, you were truly amazing today, you resolved the malfunction in just a few moves. What exactly is going on?" Wang Erzhu asked Qin Zhenhua while eating. For him, today was also incredibly surprising. After three days of coming here, he had only been cleaning the cannon chamber and attaching the tracks, and he had no idea that Qin Zhenhua was capable of this.

Others? How is that possible? Between the two of us, we have always received special care from Master Liu! Anyway, the tank has been repaired, and tomorrow, he might just turn against us

What is it like? Zhao Guodong asked Wang Erzhu.

In the factory, the master craftsman is the authority. Upon hearing the master craftsman say this, the apprentices all breathed a sigh of relief, for another day had passed

"This, well, one must understand the principles of a tank." Qin Zhenhua had nothing to hide from this brother of his, so he took a steamed bun and began to demonstrate.

How did he know? Qin Zhenhua had already put down the steamed bun, and his hand unconsciously brushed against his clothing. In the inner pocket, there was a red-covered diary.

This increases the contact area of the gears, enhancing their strength; however, it also imposes higher requirements on processing, and the assembly precision must be high. The gears are marked and must be aligned correctly.

When the tank factory was initially established, it was a complete replica of the Soviet model, with production solely focused on manufacturing and the design department solely focused on design. However, as time passed, domestic factories began to develop, and each factory established its own research and development institutions, at least capable of making small-scale improvements.

Every time they perform maintenance, the car becomes cold, so it is fine right after it is driven out, but once it heats up, the malfunction reoccurs

The technology department responsible for research and development at the factory is filled with outstanding talents. For instance, Qin Zhenhua's father is a highly sought-after individual, with both the Tank Design Institute and the Armored Corps Academy eager to recruit him. However, Qin Zhenhua's father chooses not to go anywhere and is content to remain at the factory, spending his days listening to the roar of the machines, yet...

That is a relic of my father. And today, the ease with which we can resolve issues is documented in this diary.

Oh dear, I forgot, that 59 tank's gun barrel hasn't been cleaned yet. Just then, Wang Erzhu suddenly tapped his own head.

However, this malfunction is quite subtle; it does not make any noise when the engine is cold because the gear oil inside is still viscous. The gaps in contact remain tight, but once the engine warms up, the gear oil becomes thinner, and the gaps loosen, resulting in a clattering sound.

"Yes, Director Zhao, please take care on your way out," Liu Jianzh said, turning to look around: "Well, everyone did well today, and we are all tired. Let's call it a day and finish work for today."

Although the two have only known each other for a few days, after going through these events, Wang Erzhu has already recognized Qin Zhenhua as a good friend

The power system of the Type 69 tank is largely similar to that of the Type 59 tank; however, there are innovations. For instance, its power has been enhanced, and the torque has increased. If it were to be matched with the original transmission system, it would lead to an overload phenomenon, compromising its lifespan. Therefore, it is necessary to increase the strength.

So that's how it is. Wang Erzhuz suddenly realized: "Brother Zhenhua, how did you know? I saw that Master Liu didn't understand it at all"

The meals in the cafeteria are quite simple, all identical, consisting of braised pork with vermicelli. The fatty, plump pork belly is substantial, with a bowl containing a dozen or so pieces. Outside, such a dish can only be enjoyed during the New Year. The factory's food is still quite good.

The crowd has dispersed, leaving behind only a number of tanks. Among them, the barrel of one tank is still dirty, stained with gunpowder dust and yellow copper residue.

Everyone has forgotten it, of course, some people have deliberately chosen to forget, such as Liu Dajun and Huang Chuanchuan. Who will clean this cannon? If we can escape for a day, so be it, who cares.

"That tank, there's no need to worry about it; after all, Master Liu has already agreed, let someone else take care of it," said Qin Zhenhua.

Indeed, hurry up and respond to the troops. If the repairs are not completed soon, the commander of the tank division will come and kick down my office door, said Director Zhao with a helpless smile. Alright, everyone can leave work now; it has been a long day, and it hasn't been easy.

The cafeteria is far from the repair workshop. When Wang Erzhu arrived, panting and riding his bicycle, he had just thrown down his bike when he saw Qin Zhenhua coming over on his bicycle. At this moment, the sky had completely darkened, and the streetlights cast a long shadow of him, giving off a somewhat desolate feeling

This large military factory, which is directly accessible by railway, produces tanks that are immediately loaded onto trains for shipment. When Qin Zhenhua was observing, he had just stepped off the platform, so Master Liu absolutely had no idea that there were still 69 tanks waiting for him

With one hand holding a steamed bun and the other hand holding chopsticks, Qin Zhenhua began to eat heartily.

I thought you had come directly to the cafeteria, let's go inside, you sit down, and I will get your meal for you said Wang Erzhu

A regular gear can simply be inserted, but this helical gear cannot. It requires alignment of the teeth to ensure that the marked areas on both gears are aligned. Otherwise, the gear will produce a noise due to the lack of precise engagement.

Brother Zhenhua, today was truly dangerous, you have no idea. Just after you left, Director Zhao arrived, and Master Liu took all the credit for repairing the tank for himself.

"Do not worry, just wait and see tomorrow," said Qin Zhenhua. He had just ridden his bicycle and made a round in the factory. Although he did not find what he was looking for, he saw another 69 tank from the army returning to the factory, with the same issue as today.

"I know, stop shouting, it's not good if someone hears us," Qin Zhenhua said to Wang Erzhu, seemingly distracted from the matter at hand
