The reducer, not a few days later, Wuhan school finally had news, saying that the reducer can only be transformed on the twelve-pole motor, the motor itself is more than 480 revolutions per minute, and then decelerate, after passing through the reducer at about 240 revolutions per minute, that is, the speed per second is four revolutions. This looks slow and should work.

Han Sanjiang happily installed the reducer, and only after using it did he know that the speed of the reducer had slowed down, but in the case of the motor reversing, there was a momentary dullness, and the whole part would vibrate, and the tapping wire would also be counteracted, and the teeth of the fine thread would be flawed. This problem is difficult, and in the end I had to dismantle the reducer and replace it with a speed disc, and the speed of tapping the thread was doubled, but there would be no flaws, that is, the last tooth was withdrawn, a little broken, or not ideal.

Several people pondered and pondered, and finally felt that the speed was still fast, so they discussed the problem of slowing down. Gong Xuanqun said: "Boss, this reducer is not suitable for the work of small tooth threads, and there is a counter-microshock phenomenon, resulting in two indentations on the fine teeth. This method does not work, we have to find our own way, change the spindle of the lathe, so that it decelerates in the way of a small shaft with a large shaft. We have to change this lathe spindle to a special large plate rotation, we have to measure it with the lathe manufacturer and change the spindle wheel!"

Han Sanjiang said: "Brother Xiaoyan, we don't have much time, and it will take two months for their factory to come out according to our requirements, and after a delay of these two months, our time for half a year will not be enough, and we can't make these samples! No, let's dismantle this small lathe ourselves, and then cut off the spindle shell, find a way to install a big roulette on the spindle, and take the big roulette of the rolling machine to do the test, to see if the speed is much slower, maybe it will reach the ideal value we need." ”

Mo Damin said: "Then what are you waiting for? Do it when you think of it, dismantle it, dismantle it, and then talk about it, we will always think of a way!"

Before everyone agreed, Jiang Yuanqiao picked up the hexagon wrench, dismantled it, took the spindle wheel down, and then found a large turntable on the rolling machine, modified the center distance of the spindle into a large wheel disc according to the requirements, installed it inside, displaced the lathe, let the big turntable not touch the countertop, installed these, corrected, and fixed and welded after reaching the standard. Then I tested the product, this big turntable looks much slower, the silk is also slow when it goes in, and it is also slow when it comes out, and the fine teeth that come out of this way are thick and full in appearance, and it looks as smooth as washed with water.

Han Sanjiang ate the steamed buns, picked up the sample that had just been tapped, and laughed, laughing so much that the oil in his mouth was sprayed on the silk tap.

Mo Damin snatched the sample in Han Sanjiang's hand, looked at it carefully, and said with a smile: "Boss, you really have a set, you have thought of the big turntable of this rolling machine, it's really amazing, it's amazing!"

Gong Xuanqun made a sample again, took it out and was shiny, and couldn't help shouting: "Come and see, all of you, this tooth is fuller, and the sample we brought is the same color, so yellow and smooth!"

Han Sanjiang looked at it, and then compared it with the one he did first, and found the problem, and the teeth made later were much better, more in line with the requirements of anastomosis, and the thread could be screwed in with force. He smiled, looked at the silk attack, and said, "Brothers, look, we have discovered the new continent again." Just now I ate steamed buns, laughed and sprayed some oil on the silk tap, this thread is much fuller, it seems that our thread problem has been solved, this gringo definitely did not expect, we will use this most earthy method, take the rolling machine turntable to slow down! ha······

As long as this technology overcomes the thread problem, other technologies have no content, and within two months, all these products will be developed. And did the air pressure test, water pressure test, oil pressure test, all reached the ideal standard value.

Wang Ling'er never thought that he would feel guilty for half a year, which caused Han Sanjiang and them to dig out their minds day and night to make these samples, but the emperor lived up to his wishes, and finally succeeded in two months.

After tackling the technical problems, Wang Linger went to Singapore with the sample and handed the sample to the Frenchman, who looked at it and suddenly stared at Wang Linger with wide eyes. He shouted: "Oh, myGod, this is really made by your Chinese, I can't believe it? We French people don't dare to take this batch of products, saying that they will lose money next, why do you make all of them OK, this tooth saturation, you don't have to pick it! It's really good, good, it's so OK! Can I ask, how did you make this tooth?"

Wang Ling'er always looked at him with a smile on his face, and said: "Mr. Smith, I'm sorry, I have to keep this technology secret, I said it would take half a year to make it, but our Chinese technicians only sent it for two months, and they made it, look at you, and good it, good praise! I said at the beginning, we Chinese have the wisdom, ability, and perseverance to make these things, I'm not wrong, right?"

Smith was full of beard, a typical Frenchman, smiling so much that the pockmarks on his face were crowded into a pile, and replied: "Miss Wang, your things look good, but I haven't gone through all kinds of tests, hydraulic, pneumatic, water pressure, if it's really good, I'll go to China to sign an order with you, we France, as well as the United Kingdom, Italy and several countries want to find you to do it, we can negotiate the price, we won't let you suffer, and make sure you make a lot of money!" As he spoke, he beckoned to the guy in the store and said a few words in French, and the French guy took the sample and carried it to do various tests.

Smith smiled happily and said to Wang Ling'er in stiff Chinese: "Miss Wang, you are so beautiful, I think all of you Chinese girls are as beautiful as you, I really want to go to your China for a walk, see, happily go to sign the contract, how about it?"

Wang Ling'er smiled like a peach, and replied: "Mr. Smith, thank you for your exaggeration, let's wait patiently, let's see, let's talk about it if it meets your requirements, OK!"

Smith smiled and replied: "After my eyes, 95% are qualified, according to the regulations, we have to do tests, we have to do tests, we have not passed various tests, I can't get the certificate, I can't be the master, there are a few supervisors to stamp, after the experience is received, we can officially negotiate business and sign a contract! We in France just recognize people, and please forgive me!" After saying that, he poured her a small half glass of wine, and poured a small half glass himself, shaking the wine glass to sober up.

Wang Ling'er also shook the wine glass, put it on the end of his nose and smelled it, a fresh fragrance refreshed people's hearts, and shouted: "Good wine!" Then he clinked glasses with Smith, said cheers, took a small sip, and praised: "French wine is really good, sweet and refreshing, delicious! It is worthy of being a world-famous wine!

At this time, the guy who took the sample came out, with a big mother and son, meaning that the quality was very good! Smith took this certificate and said: "Miss Wang, on the first of next month, I will take a plane to Hangzhou, call you before I go, we are very happy to cooperate with you, let's shake hands here and say goodbye, I will go to France, immediately call the audit department to audit, and then bring a translator to Hangzhou to negotiate business with you!"

Wang Ling'er shook hands and said, "Okay, then I won't go anywhere on the first of next month, I'll wait for you at home, this is my business card!" After speaking, he took out a business card from his pocket and handed it to him.

Smith looked at the business card, stuffed it into his pocket, and said, "Miss Wang, goodbye!" and let go of his hand to say goodbye.

Wang Ling'er saw Smith's anxious look, and was happy from the bottom of her heart, this guy seems to need this batch of products very much, and he is very anxious and urgent.
