The Rise of Heavy Industry 1980

Wang Song was stunned for a moment and said: "What does this matter have to

do with the development of our factory?" Wang Chaoyang smiled again and said: "Dad, if we win the battle, we have nothing to do with our Red Star, do you think I will do this?"

"Haha, I just like your boy's temper!" Wang

Song suddenly laughed, although he didn't know what specific benefits the Red Star Factory could get, but with his son's strength, the old factory director was happy when he saw it!

After discussing with Wang Song, Wang Chaoyang found Zhang Miaomiao and prepared to take this "Red Star Factory Flower" to Changhai Agricultural Machinery with him.

Zhang Miaomiao didn't have any opinions, and happily walked along.

Zhang Miaomiao has always been interested in optimizing the gearbox, and in addition to that, she has the opportunity to return to the city.

Her home is also in Nanyang City, not too far from Changhai Agricultural Machinery, so that she can live at home in the next week or so, which can be regarded as an additional benefit!

Wang Chaoyang put the finished salute in the trunk, and went to the door of Zhang Miaomiao's dormitory to help her carry the salute into the car.

At present, the shaft business of Hongxing Factory and the gear business of Sanhe Machinery have been finalized due to the design and production process, and the temporary departure of Wang Chaoyang and Zhang Miaomiao has little impact.

At four o'clock in the afternoon of the same day, Wang Chaoyang and Zhang Miaomiao arrived at Changhai Agricultural Machinery.

Since he was stationed for at least a week, Ma Sanyuan specially ordered someone to prepare Changhai Agricultural Machinery overalls for the two of them, and each person had two sets for washing.

"Chaoyang, I knew that you would definitely bring Xiao Zhang, you two are really inseparable!" Seeing Zhang Miaomiao coming back with Wang Chaoyang, Ma Sanyuan said with a smile.

"What did Chief Engineer Ma say!" Zhang Miaomiao blushed.

"Miao Miao is the main force, whether the gearbox can be optimized successfully depends on her!" Wang Chaoyang said with a smile.

The three of them entered the office building together, and finally came to the door of a separate office designated by Wang Chaoyang. This office could originally accommodate fifteen people, but now, according to Wang Chaoyang's requirements, only four office positions are left, and there is a large open space in the middle, which seems a little empty.

"Put a few potted plants in the middle, it's space now!" Ma Sanyuan was a little dissatisfied with the current layout.

"Don't potted plants. Daurson's gearbox is placed here, and our own CC20-3 is also placed on one, so that it is convenient for comparison and analysis. Then add a bookshelf and put the commonly used reference books for easy inquiry. Wang Chaoyang said.

"Oh, that's a good idea, I'll arrange someone to do it immediately!" Ma Sanyuan finished speaking, and said, "In the office of four people, you and Xiao Zhang account for two, who do you want to find

?" "I haven't thought about this yet, let's take a look and talk about it

!" After visiting the new office, Wang Chaoyang suddenly stood outside the door and said: "Chief Engineer Ma, add a sign to the door frame!"

"What brand?"

"Just write" Hongxing Factory in Changhai Agricultural Machinery Office'. "

What the hell, why are you writing this?" Ma Sanyuan didn't understand Wang Chaoyang's intentions.

"Zhang Miaomiao and I are not formal employees of your Changhai Agricultural Machinery, there must be an explanation for working here, right?

"I don't understand what you kid thinks...... But it's just a brand, there's nothing troublesome, I'll arrange someone to get it. Ma Sanyuan shook his head and said.

There was still some time before the end of work, Wang Chaoyang and Zhang Miaomiao stayed in the new office, Zhang Miaomiao cleaned up, and Wang Chaoyang and Ma Sanyuan continued to study the gearbox structure of competitors. After Zhang Miaomiao's side finished cleaning, she also devoted herself to Wang Chaoyang's discussion.

The structure of the SP3 gearbox is not complicated, it is composed of a chassis, a spindle, a driven shaft, a transmission gear set and related spare parts, and the main parameters are similar to those of the CC20-3.

The difference lies in the specific structure of the part.

For example, the most intuitive is that the two chassis are completely different.

The CC20-3 has a boxy chassis that looks like an old-fashioned box radio, while the SP3's chassis is more sleek and has a concave and convex surface, making the overall form factor smaller and more aesthetically pleasing.

"I have to say that Daurson's design ability is very strong, and the structural design of a chassis like this is very advanced, and we can't start copying it. Ma Sanyuan said with emotion while watching.

"Not necessarily. In my opinion, his design has a lot of flaws. Wang Chaoyang said.

"What flaw?" said Ma Sanyuanqi.

"For example, bearing housings. Wang Chaoyang raised his hand and pointed to the circular bearing seat protruding from the outside of the chassis.

"Daurson designed the bearing seat to protrude, which can effectively reduce the space in the box and achieve the purpose of overall weight reduction, what is the flaw of this?" Ma Sanyuan asked.

"The rounded corners are not well designed!" Before Wang Chaoyang could answer, Zhang Miaomiao couldn't help but speak.

"Fillet corners?" Ma Sanyuan was even more puzzled.

"Dowlson uses ordinary rounded corners, and if you use variable curvature rounded corners instead, the chassis will be better stressed, and maybe the wall thickness of the box can be reduced. Zhang Miaomiao said what she thought.

"The curvature round, that's what you said before, right? Oh, I think about it, that design is really clever!" Ma Sanyuan suddenly realized. In order to reduce the shaft diameter, the gooseneck fillet design is used in the two shaft parts manufactured by Hongxing Factory, which can effectively alleviate the stress concentration at the root of the shaft shoulder, which is a very unique design concept.

Again, this design concept can be applied to chassis design.

"Yes, yes, you young people are really brainy, and you can find an optimization idea so quickly, if you let Director Hu know about this, you can't jump up happily!" Ma Sanyuan patted his thigh and shouted.

Being praised like this, Zhang Miaomiao's face turned even redder: "Then I'll start calculating immediately, and strive to set the parameters as soon as possible!"

Wang Chaoyang stopped her and said, "Aren't you hungry? Look at the sky outside, let's talk about what work tomorrow!"

Zhang Miaomiao looked out the window and realized that it was already dark.

Ma Sanyuan patted his head and said: "That's right, yes, if you have any work, I'll talk about it tomorrow, and you settle down today." Let's go have a meal together, go down to the restaurant, I'll have a treat!"

Wang Chaoyang had no opinion, but Zhang Miaomiao shook his head and said: "I'm sorry Chief Engineer Ma, you and Wang Chaoyang go to eat, I want to go home directly." "

Then I'll send Miao Miao home first." Chief Engineer Ma, you should write down this meal first, and then invite you later!" Wang Chaoyang said with a smile.

"It's okay or good. Ma Sanyuan said.

Wang Chaoyang and Zhang Miaomiao got into the car, left Changhai Agricultural Machinery, and went to Zhang Miaomiao's house.

The distance is not far, less than a twenty-minute drive, and Santana stops on the side of the road in front of Zhang Miaomiao's house.

After getting out of the car, Wang Chaoyang smiled and said, "We came back suddenly, uncle and aunt should be very surprised, right?"

"......" Zhang Miaomiao froze, this sound so awkward, so I had a more awkward premonition. After

knocking on the door, Zhang Lianjun came out to open the door, and when he saw that his daughter had returned, he was really very happy, and warmly beckoned Wang Chaoyang to go into the house, and said that dinner had just been ready, and he was just going to eat together. Wang Chaoyang pushed for a while, but was still pulled into the house by Zhang Lianjun.

Zhang Miaomiao glanced at Wang Chaoyang in her busy schedule, and said in her heart that this product must have been calculated, what kind of person!
