The Rise of Heavy Industry 1980

After Zhang Miaomiao answered all the questions, Ma Sanyuan wrote and drew in the notebook for a long time, and finally stuffed the notebook back into the briefcase neatly before saying solemnly: "It's really unseemly, Xiao Zhang, you have such a high level of knowledge at such a young age

, I really admire and admire!" "Don't say that, I only learned this recently!" Zhang Miaomiao hurriedly replied. I wanted to say Wang Chaoyang's name, but when I saw that the guy was sleeping soundly, I didn't say much.

"Do you know why I rushed to you in a hurry? In fact, it is also related to the optimization of the shaft! The gearbox developed by Changhai Agricultural Machinery this time has entered the late debugging stage, but the overall performance is always not up to standard, and the foreign imports are several grades worse, I analyze that the reason is that the overall inertia is too large, resulting in slow response, and the only way to solve the problem of inertia is to reduce the shaft diameter!"

Ma Sanyuan said this, his face suddenly turned red: " But to tell you the truth, my head is about to burst, and I can't think of a way to reduce the shaft diameter, so I was so anxious when I learned that your red star had reduced the shaft diameter!"

"So you have agreed to the design of our new shaft?" Wang Song interjected and asked.

"This is not nonsense

, of course I agree, I, Ma Sanyuan, raise my hands and agree!" Ma Sanyuan said loudly: "Not only agree, but I also want to ask Xiao Zhang to help us optimize the spindle! The spindle of the gearbox has the greatest impact on the inertia, if you can reduce the shaft diameter by one to two millimeters, I will also place the order for the spindle to you Red Star!"

There are a total of two shafts in the gearbox, and the order in the hands of Red Star now has a driven shaft, the shaft diameter is smaller, and the unit price is 2.6 yuan, and the shaft diameter of the spindle is larger, reaching 24 mm, the function is more important, the structure is more complex, and the price is as high as 13.5 yuan!

When winning the order for the driven shaft, Wang Song also tried to win the spindle order, but because of the lack of processing capacity, it was ultimately unsuccessful.

Now the spindle order rekindles hope, how

not to be excited!"Lao Wang, don't be anxious and excited, Chief Engineer Ma's words are clear, you must be able to reduce the spindle shaft diameter by one to two millimeters to get the order, the spindle is not comparable to the driven shaft, you have to be prepared! Take a look at it first, this is the spindle drawing!" Liu Qingyi reminded, took out a drawing from his bag, unfolded it larger than the desktop, and it turned out to be the A2 version of the blueprint.

An axis, with the A2 diagram, shows how complex this axis is.

Wang Song stared at the spindle drawings, dizzy by countless detailed drawings and dense annotations, the previous excitement was gone, and finally had to stare at Zhang Miaomiao and said, "Xiao Zhang, you ...... Do you think it can be done?"

Zhang Miaomiao was also a little dizzy, not knowing how to answer.

"Xiao Zhang, you are talking!" Wang Song's hot temper can't stand this the most.

"I...... I...... I want to discuss with Wang Chaoyang......" Zhang Miaomiao's voice was very thin.

"What is there to discuss with that kid?" Wang Song was puzzled, but he had no patience to get to the bottom of it, walked up to Wang Chaoyang in two big strides, and slapped the back of his head, causing Wang Chaoyang, who was sleeping soundly, to suddenly wake up for seven or eight points.

Liu Qingyi and Ma Sanyuan of Changhai Agricultural Machinery couldn't help but laugh when they saw this scene, but what they were more curious about was why Zhang Miaomiao wanted to discuss with Wang Chaoyang, could this young man who had been sleeping since they met also have something extraordinary? Wang

Chaoyang rubbed his head, and his expression was painful. I don't understand why I am woken up every time I sleep soundly!

After listening to Zhang Miaomiao's introduction to the situation, Wang Chaoyang had a preliminary understanding, and he looked at the spindle drawings twice and said: "It can be optimized, but the appearance of three or four millimeters at most will be known after the specific calculation."

After hearing this, Ma Sanyuan stood up and said, "What do you say, can it be optimized by three or four millimeters?"

Wang Chaoyang nodded and said, "It should be."

Ma Sanyuan slapped the table and said: "Young man, are you taking the main axis as a child's

play?!" Wang Chaoyang was puzzled: "Why do

you say that?" Ma Sanyuan said: "You only look at it casually and say that it can reduce three or four millimeters, what is this not child's play? I have done a lifetime of design work, and I know the importance of rigor, any sloppiness may lead to product failure, and even lead to the loss of property of the people and the country, do you understand these truths?"

Wang Chaoyang didn't understand what the other party wanted to express at all, and he also knew the importance of rigor, and it was precisely because of his rigorous attitude that Wang Chaoyang said "three or four millimeters at most", rather than a specific value.

Ma Sanyuan's anger gradually calmed down, and said: "Okay, the problem of attitude is put aside for the time being, now back to my original question, do you dare to accept the optimization work of this main axis? If you take it, you will come up with a new plan within a week, if you can't take it, even if I run for nothing today!"

Wang Song, as the person who set the tone in the Red Star Factory, couldn't make up his mind this time, because these were beyond his judgment, and he could only look at Zhang Miaomiao.

Zhang Miaomiao felt the invisible pressure and turned her head to look at Wang Chaoyang. Finding that Wang Chaoyang was nodding slightly, Zhang Miaomiao said to the old factory director: "You can pick it up."

Wang Song clenched his fists and solemnly said to the two of Changhai Agricultural Machinery: "Okay, Hongxing has taken over this job!" Ma

Sanyuan nodded: "Okay, the drawings of the spindle are left to you, and the relevant parameters are also given to you, I hope to see your plan before next Monday!" Wang Song said: "Okay, before

next Monday!"

Liu Qingyi and Ma Sanyuan left in a Hongqi car, while Wang Song continued to compete with the A2 drawings of the spindle, staring at it for a while and feeling dizzy, so he had to look up and say: "Xiao Zhang, we can really optimize the spindle, right?" Zhang

Miaomiao sneered and said: "What's wrong with you, director, haven't I already said it?"

Wang Song said: "But I still don't know the bottom in ......my heart! My obedient is like a book from heaven, can you really come up with an optimization plan within a week?"

Zhang Miaomiao said: "It should be possible." In addition, the factory director, in fact, Wang Chaoyang is also very good in this regard, you should also listen to

his opinion!" Wang Song turned his head to look at Wang Chaoyang: "What opinions do you have kid, let's hear it!" Wang

Chaoyang said with a worried eye: "My opinion is, let me sleep first, and I will talk about it tomorrow...... Hey, Dad, don't you do it, is there anything to say no......"

Seeing Wang Song rolling up his arms and sleeves, Wang Chaoyang wisely fled the office as soon as possible. When Zhang Miaomiao saw this scene, she covered her mouth and wanted to laugh but was embarrassed to laugh.

Somehow, such a major matter as spindle optimization was so troubled by Wang Chaoyang, Zhang Miaomiao didn't feel the pressure at all.
