The Rise of Heavy Industry 1980

The pendulum moves back and forth, making the sound of "Gada, Gada, ......". This kind of mechanical wall clock, which was very popular in the eighties and nineties, was not gradually replaced by electronic wall clocks until after the millennium.

At this moment, in Yang Mingshan's office, this rhythmic sound is very deadly.

Sun Baoquan had collapsed, sitting on the ground and looking at the pendulum in a daze. Zhao Lichuan rubbed his palms, the corners of his mouth turned white, and he didn't know what to say.

Zhang Miaomiao clenched her small fists, and sweat like millet grains appeared on her forehead. She was very unwilling, she did so much in advance, but she was really unwilling to end up in this ending, but she couldn't do anything about it...... At this moment, she involuntarily reached out to grab her side, she knew that Wang Chaoyang was standing next to her, and she wanted to grab Wang Chaoyang's arm ...... now

As a result, a blank was caught.

Zhang Miaomiao turned her head and found that Wang Chaoyang had walked to the other end of the room at some point, where there was a large solid wood table with a complex mechanical model on it. Wang Chaoyang was unloading the gears on the model ...... at the moment

At this time, the rest of the office also noticed.

"What are you doing?" Yang Mingshan shouted. It was a model of the host system made in a one-to-one scale, which was used to demonstrate to superiors and important customers, and it was very important that he did not allow anyone to move around.

But Wang Chaoyang turned a deaf ear and continued to move. By this time, he had removed the four gears from the system model and installed the gears in his hand ......

"You, do you hear it, I'll tell you to stop immediately!" Yang

Mingshan was already at the point of being furious! He left his desk and strode towards Wang Chaoyang. Although he is in his sixties, he has always been strong in his tall stature, and he doesn't mind being rough if the other party doesn't stop.

Witnessing this scene, Zhang Miaomiao and Zhao Lichuan became even more nervous, and hurriedly ran towards Wang Chaoyang, they didn't want to see a physical conflict.

Sun Baoquan opened his mouth and stared at everything blankly, still not coming out of the collapse just now.

For a while, except for Sun Baoquan, everyone rushed towards Wang Chaoyang. And Wang Chaoyang continued to move in his hands, unaware of what was behind him.

"Brush!"

Just when Yang Mingshan rushed to Wang Chaoyang, the host system on the solid wood wide table suddenly started, the huge flywheel began to rotate, the gear structure of the two-stage speed change moved, and the end output shaft linked to the cylinder piston of the engine and began to swing up and down.

"Brush ...... ......The

complex host system suddenly "came to life" and ran very smoothly, especially the unique sound of gear occlusion, which was very beautiful.

Yang Mingshan's big hand was about to touch Wang Chaoyang's shoulder, and it suddenly stopped at this moment.

His attention was all focused on the system that had come to life.

Zhang Miaomiao and Zhao Lichuan rushed to the front, and they were also attracted by the system.

Sun Baoquan, who was depressed on the ground, continued to open his mouth wide, his eyes glazed, looking at everything in front of him.

"Gada...... Gada......" The sound of a pendulum.

"Brush ...... Brush ...... "host system sound.

The two voices intertwined, like a symphony that filled Yang Mingshan's office. Yang Mingshan himself has no intention of appreciating the "symphony", but is closely staring at the system in operation.

Although this host system is a model, it is imitated according to a one-to-one high, so it can indeed work, and Yang Mingshan himself has turned the flywheel more than once to make the system work.

However, in the past, the system model would make a "click" sound when it was running, because the transmission gear was not well matched, and there was no lubricating oil, so the sound was very harsh.

However, the system model at this moment is completely different!

"Director Yang?" Wang Chaoyang turned around at this time and smiled.

"Huh?" Yang Mingshan came back to his senses.

"That's what we're doing, and the timing is just right. Wang Chaoyang pointed to the wall clock on the wall.

"......" Yang Mingshan looked back at the wall clock, and the minute hand just coincided with the forty scale.

However, Yang Mingshan didn't look at it for long, so he said, "Don't talk about the time, tell me about you...... What is the matter with you?"

Wang Chaoyang said: "Your system model is a real scale, I put the gears we made on it, and it can be used just right." It's as simple as that.

After listening to this, Yang Mingshan bypassed Wang Chaoyang, came to the system model, and began to stare at those transmission gears. I watched it for a full minute.

At this moment, the system in operation slowly stopped, Yang Mingshan did not enjoy it, and pushed the flywheel hard, and the huge flywheel provided power to the system, and the system started to run again, making a rhythmic and clear sound.

Yang Mingshan is tall, and he has to bend down and bow his head in order to see the details on the system model, which looks very awkward, but at this moment, he is happy to do it.

After watching it like this for five minutes, Yang Mingshan came back to his senses and laughed: "Okay, very good...... Little one, what's your name?"

Wang Chaoyang.

"Your gears are very good, less than a tenth of what they used to be, and even lower if they were soaked in oil...... Tell me how you have improved!" Yang Mingshan asked, looking very interested, just like the two of them before.

"But Director Yang, we've run out of time. Wang Chaoyang said.

"If you want to say it, you can say it!" Yang Mingshan glared.

Miao Miao said. Wang Chaoyang took a step back and pulled Zhang Miaomiao over with his backhand.

Yang Mingshan found that Zhang Miaomiao was a little girl in her early twenties, frowned slightly, and said, "Little girl, then tell me, how are your gears improved?"

Zhang Miaomiao said: "We have a total of six kinds of Longyuan Heavy Industry gears, the improvement methods are not the same, I will pick one of them first! This gear module is 0.75, the number of teeth is 18, it is a light-load gear, and the material used is 45 steel. Due to the softness of the 45 steel prior to modulation, the material is squeezed during tooth machining, resulting in tooth misalignment, especially at the tooth root. Mikawa Machinery's previous gears were noisy, mainly for this reason.

"This time, after the accumulation of a large amount of data, we summarized the amount of change in tooth shape, and reserved the amount of change when the bar was fed, so that we could get a more accurate tooth shape after processing.

After hearing this, Yang Mingshan exclaimed: "Control the amount of processing deformation? As far as I know, few factories can control it like this!"

Zhang Miaomiao said: "It is indeed difficult, but it has been overcome by us."

Yang Mingshan was still in shock. As the director in charge of quality control, he knows how difficult it is to control the amount of deformation in machining. It is simply unbelievable that this method has been mastered by small factories like Mikawa Machinery or the Red Star Factory.

But the girl opposite, although she was very nervous, her eyes were very firm, which made Yang Mingshan realize that the other party did not say much.

"So what are the ways to improve the other gears...... Oh, please come here, sit down and talk slowly!" Yang Mingshan brought everyone back to his desk and stretched out his hand to signal the others to sit down.
