But it doesn’t matter whether you understand or not. What’s important is that Wang Yuan generally understood what the so-called bearings are used for, and what the so-called balls are used for.
To put it bluntly, isn't it used to reduce friction and improve mechanical transmission efficiency? How to reduce it and how to improve it? He doesn't understand the reason.
After all, their family is engaged in electricity, not mechanics. In this era, instead of relying on textbooks, it is better to rely on the influence of the family elders for this kind of thing. Just like the Wang family in Kuaiji, even the second and fifth generation are familiar with electromagnetics.
Have a certain understanding.
There are also children of the Xiangli family who can turn beads in their teens. In this era, most of the people who face the loess and back to the sky need to accumulate these skills over many years, and even if they want to learn them,
This may not be possible to master yet.
Therefore, it is very reasonable that Wang Yuan did not understand the mechanical knowledge Xiangliqin told him at all. But the problem is that although I did not understand the mechanical knowledge you mentioned before, if I think about it carefully, I doubt that you Xiangliqin
You are mentally retarded!
[No, no, no, Xiangli is definitely not mentally retarded, maybe I misunderstood.] Wang Yuan hinted to himself crazily in his heart, because in Wang Yuan's understanding, this is not a problem at all, even if the eight in their family
Even a young child knows how to answer this kind of question.
"Tao Ze, what's wrong with you?" Xiang Liqin looked at Wang Yuan and asked in confusion. He found that Wang Yuan seemed to be a little distracted.
"Are you sure it's a problem of friction?" Wang Yuan looked at Xiangli Qin and asked, shouting crazily in his heart, saying that it must not be such a simple problem, which would make him question the Xiangli family, which has been inherited since the Spring and Autumn Period by Mozi.
A line of giant families is shaken.
"Yes, because the rotation speed is too fast, friction and heat will be generated, which will cause big problems. Balls can solve part of the friction problems, but the production of balls..." Xiangliqin said with a long sigh. Recently, he has also been carving balls.
, this thing is really deadly.
"Why not let the shaft float?" Wang Yuan looked at Xiang Liqin, and finally confirmed that the other party was not joking, but was seriously solving this problem, so he replied with despair.
Although in Wang Yuan's view, this is a brain-dead problem, Xianglishi's solution is also full of all kinds of magical mechanical thinking, but if you think about it carefully, it is fundamentally wrong!
"Floating? How to float?" Xiangliqin didn't understand what Wang Yuan was talking about at all. The two sides could be said to have a true interdisciplinary exchange.
He took out the coils, magnets, etc. from his sleeves, and then used the essence of heaven and earth to convert the current into electricity. He found a random bead in Xianri's house and stuffed it in. The beads floated directly in the coil.
, it just didn’t land.
"Actually, there are several methods of levitation. Our family has recently researched this. Anything that can conduct electricity can float in it. The disadvantage is that it is hot." Wang Yuan looked at Xiangliqin helplessly,
Then I tried the permanent magnet levitation again.
"I don't know about bearings, but beads reduce friction. I really can't think of it. Our family's method is usually to make it float. Wouldn't that be better?" Wang Yuan looked at Xiangli with a strange look on his face.
Qin said, "Have you, Xiangli clan, already got the machine into your brain? You haven't thought of other methods at all, just car beads."
Xiangli Qin fell into silence at this time. This was the first time he knew that he could still play like this? But the facts were in front of him, as if he was saying, why can't he play like this?
"No, no, no, this has to bear the weight." Xiangliqin argued as much as possible. After all, the slap in the face was a bit harsh, which made Xiangliqin wonder if he had never thought of any other plan. In fact,
If we look into the reason, we can only say that Xiangli has no concept of electromagnetism.
To be more realistic, in the current world, except for Chen Xi and the guys from the Wang family in Kuaiji, no one else would think of such a thing as levitation. In this era, families that can have the concept of friction and energy consumption are already at the top of the world.
Already.
However, this argument was quickly overturned by Xiangliqin himself. After solving this aspect of the problem, load-bearing was not a problem at all, because they could use ball bearings to carry their own weight. In this case, the roundness of the balls would not matter.
The requirements are much lower.
"Tao Ze, your family has once again changed our understanding of machinery in Xiangli family."
The whole family is driving beads here.
"Grandfathers, grandmothers, uncles and uncles, please stop for a moment. The Wang family of Kuaiji has brought new technology. We may no longer need to pursue the roundness of beads." Xiangli Qin said loudly.
All the members of the Xiangli clan who were carving beads heard this, but none of them had any reaction. They were still carving beads silently. After finishing the carving of the beads in their hands, they placed them on the prepared rolling plate.
, then raised his head and looked at Xiangli Qin and Wang Yuan.
"Old Wang family, what kind of technology did they bring to us this time?" A thin and white-haired elder from the Xiangli clan looked at Wang Yuan and said.
For the Wang family in Kuaiji, the old people of Xiangli family have very good senses. Although Wang family in Kuaiji always has a little intention of running to their house to catch the autumn breeze, the technical strength of the other party is real, and Xiangli family likes to interact with them very much.
A kind of family communication about technology.
"Quick, quick, show it to the elders of my family." Xiangli Qin said quickly, and Wang Yuan felt the looks of the Xiangli family and felt a little embarrassed. He took out the things he had done before and performed them on the spot, and then the whole family of the Xiangli family
They were all shocked that such an operation was possible.
He and Wang Yuan didn't understand how much the gadget he had used to amuse his son had on mechanics. Everyone in the Xiangli family knew that just one suspension was enough to change the core design of many construction machinery.
Already.
Magnetic bearings are a new type of bearing that emerged after ball bearings in later generations have developed to their limits. Its advantages are very obvious compared to ball bearings, especially when combined with other bearings. The advantages are almost overwhelming to any previous bearing.
As for the shortcomings, it is probably just the immature technology, but anyone who sees this kind of friction force is directly driven to close to zero, the rotor speed can reach very ridiculous heights, and the abnormal rotating shaft does not need to consider the problem of mechanical heating will understand.
,Sir, times have changed!
Xianglishi also feels the same way. It really feels like times have changed.
Wang Yuan is not in this industry, so he doesn't think there is any problem with magneto-electric floating shafts. But for Xiang Lishi who is engaged in machinery, this is equivalent to directly eliminating the friction and the upper limit of rotation speed.
Mechanically it's very abnormal.
"Sure enough, our Xiangli clan has lagged behind the times." The elder of the Xiangli clan looked at the floating iron rod. After looking at each other for a few times, he said with some pity. Sure enough, in four hundred years, it is inevitable that
There will be such figures who are almost like the sages of the pre-Qin Dynasty.
Wang Yuan was under a lot of pressure at this time. All the eyes of the Xiangli family were on him, and the atmosphere was a bit solemn. Wang Yuan wanted to run away, but he looked at his little arms and legs, and then looked at the Xiangli family who were working on machines.
, it’s not a problem at all to have a wrench or something in your arms!
[Did I offend the public?] Wang Yuan thought with fear.
The per capita cultivation level of Xiangli's family is not very high, but all physical qualities are quite good. After all, those who work on machinery cannot play without any muscles.
"This thing is actually quite simple." Wang Yuan said in a low voice. These are all things that his family uses to deceive the next generation. Although the things that the Wang family has mastered are things that the Wang family cannot use at all, but they are not of any value.
It will not affect Wang's continued research.
For these families, their research does not necessarily lead to any amazing results. In many cases, they just inherit the path of their ancestors and try their best to follow this path to the end, replacing their ancestors who have been buried for hundreds or even thousands of years.
, look at the scenery at the end of this road.
Of course, no family has dared to say that it has come to an end, so this inheritance has become more and more heavy - my grandfather, my grandfather's grandfather, my ancestors, and my ancestors' ancestors all died to study this.
, there is always a feeling that I would be sorry for my ancestors if I did not continue the research, so it is necessary to continue the research.
Wang Yuan was kidnapped by a young man from the Xiangli clan because he was talking too much, and was thrown onto the Lei Ji Terrace which was being built a few miles away. Fortunately, it was a sunny day, otherwise Lei Ji Terrace would not recognize you as Wang.
His surname is still Xiangli, and he will be beaten to death whenever he comes!
After throwing Wang Yuan away, Xiang Lishi changed his mind and began to study the magnetic levitation shaft, because the technical difficulties had been overcome by the Wang family, and the mechanical design had also been overcome by Xiangli Shi. The only remaining difficulty was things like instantaneous current excitation.
This technology is not a big problem for the relatively complete secret technique of the current Han Dynasty regarding the transformation of heaven and earth essence into electric current. After all, there are many immortals studying this thing now.
Therefore, Xiang Lishi soon made the first generation magnetic levitation shaft that can be used. However, the load-bearing problem still needs to be solved by the ball shaft. Of course, the requirements for the balls are much lower at this time, but the transmission efficiency and rotor speed are far more than
Once upon a time.
The rolling balls polished by children are used in this aspect, and their efficiency is much higher than that of the giants at home who do not use magnetic levitation shafts and directly use ball shafts for shaft transmission.
This difference is completely equivalent to technological innovation. The gap between the two sides is equivalent to a Formula 1 car driven on a muddy road. Although all the accessories and technologies are the best, it can't outrun a classic car on the highway.
The magnetic levitation shaft is equivalent to such a fast lane thing, it is simply incomprehensible!
