As a small part, the nut can cause major hidden dangers. Similarly, the nut is also an important part of the high-speed rail. Japan once issued a nut that never loosens, which is widely sought after by the international community, and even exaggerated to say that Chinese high-speed rail cannot be separated from Japanese nuts. So, is this really the case? In this regard, Chinese experts speak with facts: see who is inseparable from whom?

Japanese Nuts

In Japan, there is a "Never Loose Nut" that has become one of the world's top nut manufacturers. Japanese nuts have been well received, and China is also a big fan, so the public opinion storm of "China can't do without Japanese nuts" was once blown up.

So, how powerful are Japanese nuts that they stuck with the trend of Chinese nut manufacturing?

It is reported that this nut took the founder nearly 20 years, named Hadlock nut, and currently accounts for 42% of the global high-speed rail market. The nut can withstand 30,000 times of violent vibration and has high stability. The nut has sufficient stability, and it will not loosen without replacement, and does not require subsequent reinforcement and maintenance. Japan used its strength to prove to the world that Japanese nut technology is the world's top-notch technology, which has attracted the attention of countries all over the world for a while.

It is precisely because of the superiority of Japanese nut technology that Japan exaggerates to describe its own nut technology as unique in the world, and no country can design and manufacture it. Chinese high-speed rail is inseparable from Japanese nuts? With the development of the times, high-speed rail has gradually become a means of transportation with high domestic usage. The status of high-speed rail in society has been continuously improved, and more and more people have begun to pay attention to the safety of high-speed rail. It is reported that foreign media have reported that most of the nuts used in China's high-speed rail are imported from Japan. Is this really the case? Is it true that China's high-speed rail is inseparable from the Japanese aircraft carrier? Or is Japan exaggerating?

In fact, the Japanese Hadlock nut is only one of the Chinese high-speed iron nut manufacturers. The Hadlock nut imported from Japan in the early stage of China's development of locomotives accounted for only 1%. Therefore, even if the Japanese nut is outstanding in comprehensive performance, it is not necessary to use it.

Not only that, China has already mastered the core technology of manufacturing high-performance nuts, including how to develop nuts, etc., so there is no need for China to rely on Japanese nuts.

It is reported that when China was building the Qinghai-Tibet Railway, Chinese designers developed a "self-locking nut" by themselves. The function of the self-locking nut is to rely on the generation of friction to achieve self-locking ability during use. In addition, the self-locking nut can also be shockproof and anti-loosening, and the problem of loose firmware has been solved. Chinese technical experts have proved with strength that Chinese self-locking nuts have been recognized by the international community. From this point of view, it is obvious that China is not inseparable from Japanese nuts. It is reported that self-locking nuts have been widely used in aerospace and other fields. The leap of China's scientific research is visible to the naked eye, and the nut technology has also achieved progress in the continuous research and development of designers. China has obtained superb nut technology by itself, and does not need to rely on other countries, and China saves a fortune for itself. Similarly, Chinese nut technology has been widely recognized by the world, and it has also attracted other countries to come to purchase, bringing a lot of benefits to China's manufacturing industry. All in all, our country knows that relying on others is not as good as relying on itself, so in recent years, our country has been strengthening the field of scientific research to prevent the neck as much as possible.
