After a heated discussion, everyone unanimously decided to use the method of spot paint, so that the process is the simplest, the impact on the motor is minimal, and at the same time ready to replace the spare parts of the bearing. Then it was concentrated on Li Guocheng's side.

"How's it going? Xiao Li", or Zhao Gang asked in advance.

"Limited by conditions, come up with a simple test tool, is to make a length of 10 cm vibration induction strip, everyone see, just like the antenna, the bottom is directly set on the rotating shaft, as long as the induction strip is kept in the center of the rotating shaft, according to the vibration amplitude of the induction strip can test whether the rotor is in a dynamic balance state, and at the same time make a thin induction wire of the same length, directly clamped on the casing, according to the shaking amplitude of the induction wire can also judge the stability of the motor."

Li Guocheng is also helpless, the dynamic balancing machine of later generations needs microcomputer control and calculation, which can accurately test the angle and approximate position of the imbalance, and calculate the weight of the adjustment.

On such an occasion, Li Guocheng did not dare to rely on his own mental power to adjust, otherwise the best result would be to become a tool for dynamic balance adjustment, and he would be afraid when he thought about such a day.

"It's also a way, you can try it," Zhao Gang said.

"Then I will divide the labor, Master Du and Xiao Li are responsible for manufacturing the induction strip device, we now have a depression on the place on a thin layer of paint, wait for the paint to dry naturally, let's see the effect together", in this small team, there is a faint leader, there is no clear, but everyone knows in their hearts, Zhao Gang is an engineer of a research institute, they are just senior fitters, although the status feels similar, but after all, there is still a gap in the level.

"I cooperate with Du Gong", Li Guocheng hurriedly said, Du Gong smiled and said nothing.

The next group is divided into two groups, one to fix defects and one to build induction devices.

The revision team again argued about what tools to use.

Li Guocheng followed Du Gong to find the pony, put forward the requirements for preparing materials and tools, and after a while, the pony came to the next workshop, all kinds of fitter tools are readily available, and some strips of steel are placed on the workbench.

Du Gong arranged for Li Guocheng to process the induction strip and the induction wire, and Du Gong was responsible for manufacturing the base of the induction strip and the fixture of the induction wire.

Li Guocheng took out the strength of grinding the iron rod into a needle and began the processing of strips and wires. First of all, use a large file, the bar just file into a big end to a small end of the "long needle", the action in the eyes of outsiders like a mallet, do not measure not to say, the action is so rude, but if you look closely, you will find that each file is an inclination, the shape of the long needle gradually appears, the surface is uniform, there are no obvious steps.

After observing the rough work, he changed to a fine file and carefully and precisely polished, but it still seemed to outsiders to be a mallet.

Then change the fine sandpaper and polish it slowly.

After an hour of procrastination, the finished product is placed on the workbench. At this time, Du Gong's work is also nearing the end, after all, the base and fixture are pediatric for senior fitters, and the main work is repeated calibration and measurement.

When Du Gong heard that Li Guocheng had completed the work, his first reaction was impossible, and the idea of whether he was foolish or not popped up in his heart, but when he thought about it, he felt that he shouldn't, and Xiao Li was not an outrageous person.

Du Gong put the "big needle" on the countertop, picked up the right-angle steel ruler, leaned on the big needle with the right-angled side, and found that there was no gap, and then rotated the steel ruler on the side axis, while observing, there was also no gap, which was the perfect processing. What's even more incredible is the time, it's too short. They usually need to process such workpieces while measuring, and the time can be more than half a day, and they don't have such high accuracy.

Replacing the "fine needle" measurement, the same result, Du Gong looked at Li Guocheng with the eyes of a monster, and he didn't know what to say.

Li Guocheng also wants to show his fitter ability, and everyone in the province looks down on him. But what he didn't expect was that the strength was too strong.

"Your craft is indeed the material of dry fitters", Du Gong sighed.

Next is welding, Du Gong wanted to continue to see Li Guocheng's welding skills, so he gave up the position to Li Guocheng. Li Guocheng did not push, with two right-angle steel rulers to complete the basic positioning, first spot welded a point, and then then positioned, with the assistance of the mind, Li Guocheng completed the welding work like a cloud.

Du Gong also picked up two right-angle steel rulers, measured them at all angles, and found that he couldn't find anything that needed to be adjusted, and secretly admired Li Guocheng's welding skills and stable operation throughout the whole process, and sighed that the young man was too violent.

Because the paint needs to be dried thoroughly before the experiment, everyone chose natural air drying, for fear that the heating would affect other parameters.

In the evening of the same day, the Security Department of the Ministry of Mechanical and Electrical Affairs received an anonymous letter reporting that Li Guocheng was an enemy agent, and the evidence was that it was impossible for China to know the theory of dynamic balance at his age, and it must have been secretly cultivated abroad, with the purpose of breaking into the state secret laboratory and stealing information.

In an internal meeting attended by Wang Peiyi, after listening to Wang Peiyi's opinions, it was decided to make a secret visit to monitor Li Guocheng's walking, and not to arrest him for the time being. That night, several groups went to the courtyard, the factory, and the junior high school where Li Guocheng was studying and began a secret visit.

The next morning, everyone got together, and when there was nothing to do, they carefully observed the details of the motor. In the afternoon, the assembly began, Du Gong did it himself, after the motor completed the assembly, carefully installed the induction strip and the induction wire, and used the instrument to ensure that the induction strip was on the axis of the rotating shaft.

Then I turned on the camera and observed, and found that the vibration did become a little smaller, and everyone's confidence was even stronger.

After that, everyone kept trying, at the beginning the progress was obvious, and then sometimes it was good, sometimes it was bad, and finally Li Guocheng used his telekinesis to assist, and he ordered it a few times by himself, and finally after half a month, in addition to the induction wire, there was a slight shaking, and the induction bar could no longer see any shaking with the naked eye.

Removing the sensor strip and sensor wire, and trying the noise, it surprisingly reached 28 decibels.

The next two days will be the summary meeting and the commendation meeting. The summary is based on the assembly experiment at this stage, the assembly process is set step by step and process, and the manufacturing process and requirements of the induction strip and induction wire are summarized into a book. Later, everyone felt that the names of the induction strip and the induction wire were too earthy, so they were changed to the axis balance ruler and the longitudinal stability ruler respectively.

Because the wind has risen, the commendation is mainly verbal praise and an enamel water cup.

At the end of the meeting, everyone cherished each other and happily went home or returned to the unit, Li Guocheng was left by Wang Peiyi on the grounds that there was something, and everyone didn't care, only Wei Haibin was ecstatic in his heart.

Li Guocheng, who was cloudy, was taken to a room with a hanging meeting room, in which sat a middle-aged man and a young man.

Li Guocheng immediately released his mental power, there was nothing abnormal around, and he saw Deputy Director Li in an office on the second floor, talking to a middle-aged man with an anxious face.
