Ten minutes later, Liu Yao disassembled the center bearing, and after a closer look, Liu Yao found that the center line of the box hole of the machine and the shaft center line of the inner ring of the center bearing were skewed!

Liu Yao got down from the machine and bowed to Qin Yu with a look of admiration: "Qin Gong, you are so powerful, just feel the vibration, you can determine the location of the fault!"

Qin Yu smiled a little embarrassedly: "At that time, learning mechanic technology was just a temporary play, and I haven't been in contact with this industry for two years, so it's a little rusty, otherwise, just listening to the sound made by the machine, I should have judged the location of the fault, and I still regressed! If I compete with Schneider again, I'm afraid that the one who loses will be me." ”

Qin Yu's words made Liu Yao fall into a fog, and he felt like he was listening to a book from heaven! Qin Yu in front of him completely subverted Liu Yao's perception of a technician!

In Liu Yao's mind, technician skills can only be improved after decades of accumulation and countless practices, but how old is Qin Yu?

"Qin Gong is humble! Even if he competes a hundred times, the one who loses is Schneider!" Just when Liu Yao was dizzy, a vigorous and powerful voice came from behind him!

Hearing this voice, Liu Yao hurriedly turned around and bowed to the visitor in a proper manner: "Teacher, are you really here?"

Qin Yu turned his head to look and saw a Chinese face, looking a tough old man, the old man's two hands have very large joints, at first glance, he is a person who often does manual work, but the skin on the old man's face is well maintained, ruddy and shiny, and he does not look like a coolie at all.

Qin Yu's eyes lit up, yes, this old man has already touched the threshold of an S-level technician! It seems that Huaxia is very promising to produce an S-level technician.

Wu Wen nodded to Liu Yao, and then bowed to Qin Yu respectfully: "Wu Wen has seen Qin Gong. ”

"Wu Gong, have we met?" Qin Yu felt that Wu Wen was a little familiar.

"Qin Gong has a really good memory, and we had a relationship in Berlin. I will never forget your demeanor at that time!"

Qin Yu's eyebrows were raised, and a bright smile appeared on his face: "I remember, I remember that in the final, a bookmaker opened a betting market, and Wu Gong was the only one who pressed me to win." ”

"Hahaha...... Thanks to Qin Gong's blessing, that time, I earned 200 million. I didn't expect to see each other again!"

"Yes, fate is amazing. Qin Yu nodded.

While the two were talking, Liu Yao went to the warehouse to get a new center bearing back, and then climbed on the machine neatly, because his teacher was there, Liu Yao was very cautious.

Liu Yao wiped the center bearing very carefully to ensure that there were no small metal particles attached to the center bearing, and wiped the connection between the center bearing and the machine, and then began to calibrate the position.

Liu Yao proofread several times to ensure that the installation position was very accurate, and then the installation began.

Wu Wen was very satisfied with his apprentice's cautious attitude: "Yes, after so many years, Xiao Liu has not forgotten his original intention, be careful when applying force, and avoid rolling force." ”

"Yes, Teacher!"

Liu Yao nodded, heated it with a bearing heater, and then carefully pressed the center bearing into the joint, and smoothly installed the center bearing.

There was no problem with this process, and Qin Yu also nodded, indicating that Liu Yao had done a good job.

Seeing Qin Yu nodding, Liu Yao let out a sigh of relief, but he didn't dare to relax, because installing the center bearing was only the first step, and after the center bearing was installed, the gears needed to be corrected, which was a hard work and fine work.

In order to show in front of the teacher, Liu Yao did not rest, wiped his sweat with his greasy sleeves, and began to look for the gear that had problems.

This time, Liu Yao didn't deal with it, but carefully proofread all the gears to confirm that everything was safe, and then jumped off the machine.

"Teacher, please check it out. ”

Wu Wen nodded: "It's still good, it has reached the peak level of a senior mechanic, but there is still a certain distance from a stunt mechanic." ”

"Ask the teacher for advice. ”

"You're just adjusting the gears that are in contact, but there's a correlation between the gears that aren't in contact. Now it seems that all the gears have been trimmed, but in fact, at most two months, the gears will deviate again. ”

Qin Yu nodded slightly, he felt that what Wu Wen said was good.

Wu Wen's words made Liu Yao's eyes light up, and Liu Yao seemed to see a brand new path!

Liu Yao bowed deeply: "Thank you for the teacher's guidance! ”

"Okay! The old man is offering his ugliness in front of Qin Gong!"

Wu Wen climbed onto the machine very neatly, not at all like an old man in his seventies. Based on his own experience, Wu Wen fine-tuned the associated gears.

While adjusting, he said: "This gear and the main gear seem to be unable to hit eight poles, but in fact, its amplitude will affect the amplitude of the host wheel, so its amplitude must be lowered." The shaft driven by this gear will affect the rotation of the main gear, so this also needs to be adjusted......"

After some adjustments, Wu Wen jumped off the machine, Wu Wen clapped his hands and looked at Qin Yu with an inquiring gaze: "Qin Gong, please give me some advice." ”

Qin Yu smiled and said lightly: "Wu Gong, you are already very close to an S-level technician, the adjustment is very good, after your adjustment, this machine will not break down for at least half a year." ”

Is it just close to an S-level technician? Wu Wen's face showed a trace of disappointment, if someone else said this, Wu Wen would definitely refute it, but the person who said this was Qin Yu.

Seeing the disappointment on the teacher's face, Liu Yao said a little unconvinced: "Qin Gong, the teacher's adjustment is already perfect, why is it just close to an S-level technician? Moreover, if you want to test it, you must start it and try it out, and you haven't even turned it on, how can you assert it?"

"Then turn it on. Qin Yu made a gesture of please.

Liu Yao hurriedly turned on the machine, the machine roared, the roaring sound was obviously much smaller than just now, much lighter, Liu Yao knew that after the teacher's adjustment, the load of the machine became much smaller!

Soon, the raw material is ground into chips and falls into the scrap area. Liu Yao's eyes widened!

"Oh my God! The teacher actually adjusted the effect of the middle grinding! This is definitely the level of an S-level technician! Qin Gong, now you have a good eye, right?"

Qin Yu shook his head lightly: "Punch the eyes?" hehe...... If a machine with only a coarse grinding function can be adjusted to achieve medium grinding, it is indeed the level of an S-class technician. However, this machine originally had the function of medium grinding, and it was only because of poor maintenance that it degenerated to a rough grind, and restoring it to the level of medium grinding was just the level of a stunt mechanic. ”
