Li Jia carried a simple and durable blue printing and dyeing cloth bag and walked towards Liu Ruiyang.

"Boss, isn't it time to go see her?"

Liu Ruiyang raised his head and frowned slightly, this boss screamed awkwardly. Although these guys obey him and respect him, their faces are not respectful, they laugh freely, and they speak without turning or evading, and in the past few days, somehow, they all call the boss vividly.

"She has been locked up in the hut for more than ten days, and no one comes out even if she is on the phone. You have to be concerned about it often, it's not easy to come all the way from the United States. Li Jia smiled hesitantly, took out a plastic crisper from the cloth bag, full of fruits, with cantaloupe on one side and peaches on the other, all cut into pieces, well-proportioned, stacked together, very exquisite, and on the edge of a peach, there were two toothpicks. He threw his head back, "The hands of the sisters...... The brothers and sisters are very concerned about her, and when they heard that fruits in the United States are scarce and expensive, they thought about collecting good fruits, thinking that they would not be wronged by their sister-in-law...... Barrister. He put the crisper back into the cloth bag and stuffed the belt into Liu Ruiyang's hand. Looking at the capacity of the cloth bag, there are three boxes of cut fruit inside.

Liu Ruiyang couldn't cry or laugh, took the cloth bag, and glanced at his colleagues, they didn't stop working in their hands, their eyes were looking here, and they all had smiles on their faces. Liu Ruiyang didn't shirk it, he was thinking about going to see Ling Yuanruo.

Li Jia followed him out of the door, "I'll send you over." ”

On the way, Liu Ruiyang's phone rang, picked it up and took a look. Li Jia looked at his face and knew that it was Ling Yuanruo, and said with a smile, "I said it's time to go!" ”

Liu Ruiyang glared at him and answered the phone. "I found something that probably makes a lot of sense. If it's convenient, you can call them all. Ling Yuanruo's voice was faintly excited.

When Li Yi also arrived, the three of them were eating cantaloupe and waiting for him.

Li Jia inserted a piece with a new toothpick and handed it to Li Yi. Li Yi sat down, the cantaloupe had not yet been delivered to his mouth, and he heard Ling Yuanruo ask, "How does the Kunpeng reducer solve the accuracy problem?" ”

Li Yi held a toothpick and thought about how to answer.

"In layman's terms. I wanted to see if my understanding was correct. ”

"It's still the old way, over-profit cooperation." Li Yi took a bite of cantaloupe and explained that it can be simply understood that the accuracy of the reducer mainly depends on the degree of meshing of the gears. If the gap is too large and the meshing is not good, the accuracy will not come up. The common method of domestic reducer is interference fit, so that the gears are squeezed tightly together, eliminating all possible clearances, so that the product can achieve high precision when the material and process are not ideal. But the cost comes with too tight assembly, which can lead to excessive internal stresses and excessive wear. On the other hand, excess wear will soon form new gaps or even loosen, and the accuracy will decline rapidly. This is also why many domestic reducers have excellent factory performance, but after half a year, various problems have appeared one after another, and the performance has declined rapidly, and even the basic requirements cannot be met, so they can only be scrapped.

"However, if you have an interference fit, it will cause noise and heat, right?"

"Yes. Mechanical noise and heat generation indicate poor local gear meshing, which usually performs unsatisfactory in terms of stability and life. ”

"At the beginning, the Kunpeng reducer was also troubled by noise and heat, and some of the heat generation was even amazing. But when it came time for mass production, these two indicators dropped quickly. Is it to solve these two problems? ”

Li Yi shook his head, "The only way to really solve the problem is to honestly improve the level of craftsmanship." Materials, equipment, heat treatment, grinding, assembly, testing...... The precision of production and assembly has been comprehensively improved, and the accuracy of products will naturally go up. However, it is not possible in the short term, so I have to think of other ways. ”

"How?"

"It's Liu Gong's train of thought." Li Yi turned to Liu Ruiyang, "Say it, you know it better than me." ”

Ling Yuanruo looked at Liu Ruiyang.

"60% of the reducer in the early stage has obvious noise and heat, that is, 40% of the interference degree is reasonable, or the gear is well matched, and there is no need for micro interference. Our parts are assembled randomly, and I wondered if we could find the systematic difference between the 40% and 60% of the differences, and whether it was possible that the errors were synchronized. Liu Ruiyang looked at Ling Yuanruo, stopped and made an analogy, just like screws and screw caps, if the machining accuracy is high enough and the caliber error is well controlled, any screw and any screw cap can be screwed perfectly. If the machining accuracy is not enough and the error is large, then the two screws and the screw cap are either too loose or too tight, and the proportion of perfect screwing is not high. But what does it mean if it can be screwed perfectly?

"What does it mean?"

"It's possible that the errors of these two parts have come together. The screw is 1 mm larger than the design standard, but the screw cap is also just 1 mm larger. ”

"Aha!" Ling Yuanruo knocked on the table with some excitement.

"The situation with gearboxes is much more complicated, but the basic principle is the same. We model the image of the parts, summarize and analyze the error synchronization patterns with algorithms, and match the parts that are not accurate enough but work well with each other before entering the assembly process. ”

"What percentage of the improvement in accuracy do you think can be attributed to this approach?"

Liu Ruiyang looked at Li Yi, Li Yi touched his chin, "We haven't made an accurate estimate...... After all, we don't just do one thing to improve accuracy. However, judging by the previous data, I believe that at least half. Or much taller than half. Ling Yuanruo stood up and rubbed his hands, "Such an outstanding idea and achievement, why did you introduce it to me so lightly when you introduced it to me before?" ”

Liu Ruiyang was very happy about Ling Yuanruo's warm recognition, but he still honestly admitted, "This is really not an achievement." It's essentially a patch that gives us a patch for the bug that doesn't produce enough accuracy. ”

"After all, it worked to solve the problem, didn't it?"

"In fact, it is contrary to the spirit of modern industry, because we have to treat each component special and deal with it individually. Solving the standardization problem with the least standardized method is very harmful to cost and efficiency. And these, Emperor Gong Group can do directly on the production line, fast response, low cost. ”

"That's even better!"

"Huh?" Liu Ruiyang was stunned, and Li Yi and Li Jia also looked at Ling Yuanruo in confusion, not understanding what was good.

This doesn't mean that the methods and ideas of the Emperor Gong Group, that is, the patent, have not brought too many bonuses to the Kunpeng reducer. It can even prove that they can't do what you can. ”

"That's right!" Li Jia was the first to slap the table, and Chong Lingyuanruo gave a thumbs up, "They can't do it, so naturally it's not our infringement." ”

"This is our starting point, and I will dig down and build a complete response strategy." Ling Yuanruo couldn't hide his excitement, turned his head to Liu Ruiyang and said, "By the way, I do think that your solution itself is very good. You're looking at things from the lion's point of view. Your solution is meaningless to Emperor Gong Group, but for the catch-up countries of late-developing countries, those companies in the same situation as Kunpeng Robot, the significance is greater than you think. The meaning may even be strategic – similar to the concept of a human civilization skill tree. ”

"The lion and the antelope......" Liu Ruiyang said with a little contemplation, his eyes flashed with joy beyond expectation, as if he accidentally saw a long-admired book at a used book stall he frequented, and as if he saw Ling Yuanruo inside. I'll have to ask you about that next time. Ling Yuanruo smiled, "Okay." ”

Li Yi hurriedly said, "Call me, this question is really ......"

Li Jia slapped him on the thigh with a hard palm and stuffed a piece of cantaloupe into his mouth, "Eat melon, masses!" ”
