Chapter 969: Snipe and clam fight, fisherman gains profit
"Huh? What's the problem?"
The comrade who asked this question raised the document in his hand: "You can read it yourself."
Each of these documents is a general recommendation list of a ministries and commissions, and each of the documents in his hands has the same name on each list.
"Comrade Gao Zhendong".
This is difficult to solve. The recommendations of these ministries and commissions have praised Gao Zhendong very much. Although the full text is full of "responsible for XX topics", "developing XX technology", and "taking the lead in completing the research of XX equipment", there are even more results than can be seen directly.
However, it can be clearly felt between the lines that the leaders of these ministries and commissions have high evaluations of Comrade Gao Zhendong.
At the same time, these ministries and commissions have the same meaning inside and outside: "This person is from the work field of our ministries (committee). No matter where others are related, it is for work needs. However, the scientific department to which this person belongs must be divided into us."
Looking at these ministries and commissions put the comrades present in a dilemma.
This is too popular and is not suitable for anywhere.
The 17th Ministry of Machinery, the 12th Ministry of Machinery, the Defense Work Committee, the Ministry of Chemical Industry, the Postal Communications Commission...
Even the Agriculture, the 11th Ministry of Machinery, the Ministry of Foreign Affairs, and the Education and Training Commission were all joining in the fun, but they didn’t blatantly grab people, but the recommendation was given solidly.
"It's obvious that in the past, I was suppressed by the superiors for protection. Now it's probably because the superiors and relevant ministries have let go, and they have rushed in. It's hard to do it..."
No one here is easy to offend, and the key is that others have a lot of reasons. If you just look at the family, you will feel that it is simply unscientific not to put this person in their place.
The Gao operation line and the 6011 battle of the 17th Ministry of Machinery, as well as a bunch of XX results.
There are many world-class firsts in the computer science and semiconductors of the 12th Ministry of Machinery, as well as civil consumer electronics products and a bunch of professional textbooks that are now used by major universities.
The Defense Work Committee was even more XX throughout the whole process. There was no real thing to see, but instead they seemed to have more reasons.
The Ministry of Yinghua is better, not even XX, but only said that it has made significant contributions in important areas, and even has no way to provoke it.
The Postal Commission is relatively simple, just five words, program-controlled switch, you can do it.
Looking at these recommended lists, the comrades from the Academy of Sciences are one and two big.
What's wrong with this?
If you want to say that you are qualified, it is definitely enough. This is not enough, so there are only a few people left in the Department of Technology and Science.
But where to put it? This is very difficult to deal with.
Everyone looked at me, I looked at you, and suddenly someone started to laugh.
"By the way, I have a recommendation form here. I just brought it here, please take a look."
I looked up and saw that I was from the Institute of Science and Technology, from the Ministry of Mathematics, Physics and Chemistry. No wonder I brought it here. Anyway, it’s not too late to bring it here within the Science and Technology Academy.
"You are..." The other comrades looked at him with a confused look on their faces. Why are you a natural science person joining in the fun?
"Look, you'll know after you look." The comrade smiled proudly.
A comrade opened it and saw that Gao Zhendong was in the list.
Comrade Gao Zhendong was recommended as a scientific member of the Natural Science Mathematics Physics and Chemistry Branch, and the reasons are also very hard-core.
——Theoretical research of lasers and the invention and application of lasers.
"You... are you joining in the fun?" Some comrades couldn't laugh or cry.
But this reason is very sufficient. Laser is definitely high-energy physics, and it is the first in the world for the country. This reason is simply high and hard, and there is no room for doubt.
Moreover, this comrade is not only a theory, but also very familiar in application. Putting aside the applications that may be submerged in those XX, the original research institute of the Academy of Sciences alone is developing a laser application project under the leadership of others, and results will be produced soon. Judging from the current situation, progress and results, it is extremely gratifying.
"Okay! This method is good!" A comrade from the Academy of Sciences patted the table, and the more he thought about it, the more he felt that this trick was wonderful.
Difficult to deal with? Then don’t do it!
You guys are robbing people, right? Don't snatch it, it's ours!
No matter how sufficient your reasons are, they are not as strong as our "world number one". Even if there are so many world number ones like the Twelve Machinery Department, they are not as high-end as lasers and high-energy physics!
Some ministries and commissions are "high", while others are "hard", and we are tall and hard here!
In this way, no ministries or commissions are allowed to offend, and this comrade is placed at a high enough level.
"You have to have many ways to do theory, think carefully, just do it!"
Other comrades also agreed, "Yeah, yeah, this method is good."
"Yes, it's better to put such comrades in the natural sciences side of our Academy of Sciences."
"This is good. Application is just a move, and theory is the general outline."
"This is called fighting between snipe and clam, and the fisherman will benefit."
“…”
The list was reported to it soon. A leader looked at the list and laughed when he saw Gao Zhendong: "There is such a skill in the science and technology institute, hahaha. Well, this comrade is just like this, it's not bad."
——
Although Gao Zhendong himself has decided on this matter, it is still some time before the announcement. Gao Zhendong's such a thing are naturally not controversial, but there is something else to discuss.
However, Gao Zhendong didn't know about this. He was looking at a machine tool in front of him.
"General Engineer Gao, comrades from Guangyang Factory have made the absolute multi-circle encoder you taught them. It has been installed and tried, and the effect is very good, but we have encountered new problems."
"Oh? What's new question." Looking at the sizzling machine tool, a steel cutting tool just passed, and the iron chips immediately turned blue.
This seems to be a bit big? Which machine-operated program is programmed?
Gao Zhendong was thinking about these unreliable things in his heart while listening to his comrades’ reports.
The newest ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!
"The accuracy is now clear. At least the transmission accuracy of the reducer is insufficient, which leads to the final workpiece accuracy not increasing."
There are more places to use transmission on machine tools, such as spindle, rotation, and feeding...
Gao Zhendong thought for a while and asked, "Just just drive? Is the motor okay?"
For machine tools, if you want to precisely control such as the feed quantity, the motor responsible for this quantity is firstly precisely controllable.
"We are now using a high-precision stepper motor imported from Gallic. After deceleration, if the reduction transmission mechanism is fine, the theoretical calculation can meet the requirements. However, the reduction transmission mechanism itself is not accurate enough, and it is not easy for us to determine whether there is any problem after the stepper motor is installed."
The servo motor has not been made yet, so the relevant equipment we can get in our hands is the stepper motor. Fortunately, we have the Gaul Chicken channel, and the performance and parameters of the stepper motor in our hands are not bad.
Gao Zhendong was a little surprised: "The motion control accuracy of the lithography machine is already very high. Why can't it work on the machine tool?"
These masters of Yi Zhonghai knew about this: "The lithography machine can be adjusted, and there are positioning marks on the mask, so the purpose can be achieved through repeated detection and adjustment. But the machine tool does not have this opportunity. If you continue with one knife, you can't adjust it even if you want."
Gao Zhendong suddenly realized, Oh, if you don’t move the knife, everything will be fine, and using the knife is another matter.
He thought about it and found that he was really not familiar with the transmission of the machine tool, but he knew some precision transmission devices. He was in contact with the robot when he followed his mentor to do it, and he didn't know if it could be used.
"Let me first, what kind of transmission device do you need?"
"The parameters of transmission accuracy, backlash, transmission error, and air range must be good. There are no high requirements for transmission efficiency, starting torque, etc. It is best to have a larger transmission ratio, and the load capacity is not certain. Some requirements are large and some require smaller requirements, but the overall requirements for machine tools are not particularly high. As for dynamic characteristics, I can't take care of those." A collaborative comrade from the 11th Machinery Department reported.
"What reducer are you using now?"
"High-precision lead screws and planetary reducers, needless to say, those with low precision are fine. The main problem is still on planetary reducers."
Gao Zhendong looked at the parameters of their planetary reducer and was very happy. Hey, I really understand this thing a little bit, just like the planetary gear reducer can be replaced with the function. Thanks to the robot for the gift.
Gao Zhendong recalled it in his mind, well, the things in his memory are barely enough, at least they can explain things clearly to others.
He pretended to think for a while, but the comrade next to him did not dare to disturb him, turned off the machine tool and waited.
"There are two methods. One is more accurate but has a lower load capacity, and has high requirements for materials. The other is higher load capacity but has a lower accuracy. However, it is much better than what you use now, but it also has certain requirements for processing. Which one do you choose?"
Is this a good idea? No, Mr. Gao, do you still have to choose this? We want it all!
"Mr. Gao, tell us everything. Let's use it while choosing, hehe." The young man from the third branch factory knew that Gao Zhendong was not a person who cherished himself, so he said it was very relaxed and lively.
"Uh... it's right." Gao Zhendong felt that he asked a fool, "Who is a comrade who is engaged in technology these days just shines when he sees new technology?"
Gao Zhendong turned around and drew a picture on the blackboard next to the machine tool. This is the test workshop, and everything is inside.
This thing looks like a ring gear on the outside and a gear on the inside. There is a gap between the two and there is no direct contact.
"Huh? Gao always draws the gear wrongly. The number of gear teeth does not match. It is two fewer teeth than the outer ring ring."
"Shh, this is a schematic diagram. It doesn't matter if there are more teeth and less teeth."
"No, this thing can't be driven. Could it be that the gears roll along the ring? Then the middle shaft will not rotate, but will be turned in a circle. This is useless."
However, Gao Zhendong didn't care about everyone's questions and patted the chalk gray on his hand: "This is the first type, the harmonic reducer."
