Qian Longcheng looked at the pile of gears next to Zhou Jingming, with a smile on his face, "It seems that you are very confident in the gears you have produced! You must know that the strength check test of the gear is not something you can pass by talking, once the strength test fails to meet the requirements, you know the results." ”

"If you don't have diamonds, don't do porcelain work. Director Qian, please rest assured, since I dare to come over with these gears, I naturally have the bottom in my heart, otherwise I am embarrassed to ask Director Xu to introduce me. Zhou Jingming replied with a smile.

"Old money, you just do what Xiao Zhou said, take this set of shift gears to do a strength test, if the strength can not meet the requirements, what should you do, the gearbox as the core component of the car, any of the components in it, can not tolerate a little sloppy. Xu Guanglu on the side also said.

"Okay, then I'll have someone take it for a strength test. Qian Longcheng smiled and continued, "I just counted the number of gear teeth you brought over, it seems to be different from the previous one, the number of gear teeth is five more than the gears we use now, why is this?"

Zhou Jingming also had a smile on his face, since his change in gears could be seen by Qian Longcheng, it was naturally better.

"The increase in the number of teeth is because I changed the modulus of gear production, the original gear factory produced the same modulus, this is done to facilitate production, and the gears used in the gearbox factory should also be the same modulus. Zhou Jingming paused, and then continued, "Using the same modulus naturally has its benefits, but in this way, it will inevitably reduce the strength of the shift gear, and the tooth fracture in front of me is estimated to have such a reason." ”

"Reducing the modulus of the gear will indeed increase the number of teeth, and it will also increase the coincidence of gear meshing, but the key is how you distribute the modulus between the shift gears, whether it is that each shift gear uses a different modulus, so for you, the process requirements are too high. ”

Qian Longcheng's eyes lit up, he didn't expect that Zhou Jingming knew a lot about the design of gears, so he couldn't help but ask more.

"Of course, it won't be as Mr. Qian said, the gearboxes produced by Mr. Qian here are all five-speed gearboxes, for the first gear and the second gear, the two gears, I choose a larger modulus, and the rest of the high-grade gears, is used in another smaller modulus, that is, the shift gear in the entire gearbox, a total of two modulus. Zhou Jingming replied with a smile.

The selection of various parameters of the shift gear is exquisite, and there are several parameters that are incompatible, and it is necessary to make a trade-off between the requirements of the car performance in order to achieve the best driving experience.

The look of appreciation on Qian Longcheng's face was even worse, and then, he asked a lot of questions about gear design and production, and Zhou Jingming was able to answer them fluently, and gave some of his own unique insights from different angles.

"No wonder the leaders of the ministry and commission will value you so much, I now understand why, a small gear, you can say so much, really talent! Lao Xu, I am now more and more envious of you, with such a capable leader, no wonder the production index of your car factory this year is rising!" Qian Longcheng said with emotion.

Xu Guanglu on the side was full of pride, although he didn't participate in the conversation just now, but he listened to it almost, in his opinion, it seems that there is no place that Zhou Jingming doesn't understand, as long as it can be related to the car, Zhou Jingming can become an expert in this area in an instant!

This is what surprised Xu Guanglu the most!

"Okay old money, don't say these words of appreciation, Xiao Zhou came here today to talk to you about cooperation, not to listen to you say this. You hurry up and arrange for the people in your factory to do this strength test, so you can give Xiao Zhou an answer as soon as possible. Xu Guanglu urged on the side.

"I'll arrange it right away, and I'll be able to get back to you in three days at most. Qian Longcheng replied.

is different from He Tianfa before, he is purely just to make money, and he basically knows nothing about gear production, but Zhou Jingming is different, Qian Longcheng can see that although Zhou Jingming is not very old, he is definitely an expert in this aspect, talking to Zhou Jingming, Qian Longcheng feels extremely relaxed, and he even feels that even if the strength test is unqualified this time, he is willing to give Zhou Jingming a chance to cooperate.

After talking about this matter, at the invitation of Qian Longcheng, several people visited the transmission factory again, and then followed Xu Guanglu back to the car factory.

"Director, thank you so much for today's events. After getting out of the car, Zhou Jingming said to Xu Guanglu gratefully.

"Thank me for what are you doing! I should also help you for your contribution to our factory, and I only help you introduce old money, and the rest is not doing anything, mainly relying on yourself. Xu Guanglu responded with a smile.

"Anyway, I have been in the car factory for so many days, and the factory director and senior brother have taken good care of me, and I should thank you. ”

"You work hard and make a career, which is our greatest thanks, and today I look at the old money, your single business, should not be able to run away. If you encounter any difficulties in the future, just come to me, and I will do my best to help you within the scope of my ability. ”

After a good night's rest, the next morning, Zhou Jingming and He Yingxun came to the gear factory again, and the parts of the three milling machines were not replaced.

At the same time, Uncle Liu and several other workers also spontaneously organized themselves and carefully cleaned up the entire factory, cleaning up all the useless sundries and other things.

In the afternoon, after Zhou Jingming and He Yingxun were busy with the equipment, they went to the building materials market to buy some cement or something, and were ready to find someone to repair the factory's current dormitory, that is, the dilapidated warehouse.

However, Uncle Liu and these people are all from the countryside, and they also know a lot about building houses, and they also know that the factory is currently in financial difficulties, so they can save a little bit, and a few people will finish the repair work of the warehouse by themselves as soon as they say hello.

In this way, after this day's efforts, the entire gear factory has a new look, and now we are waiting for the reply from the gearbox factory, and we can officially start work.

Until the afternoon of the next day, Zhou Jingming, who had been working for several days, finally had time to sit in the library, read books quietly and relax, but at this time, He Yingxun hurriedly walked into the library and found Zhou Jingming, with undisguised joy on his face,

"Director Zhao just told me that the strength test results of the gearbox factory have come out, and the gears we produce fully meet the strength requirements. ”
