China Aero Engine Pain

"The company provides all possible help." This is the first official voice of the China Axis Association for the application of China Hailin Company to investigate the suspected dumping of US Timken Company in China. How to curb the trend of the Chinese bearing industry to move into the high-end bearing sector may have become the top priority of the world's bearing giants for the Chinese bearing industry's containment strategy.

Why did the bearing technology talents fail to meet the requirements of the Ministry of Industry and Information Technology? In 2011, the Ministry of Industry and Information Technology released the “12th Five-Year Development Plan for Basic Mechanical Components, Basic Manufacturing Processes and Basic Materials Industry” (abbreviated as “Three-Base Project”), but it ignored Based on the training of relevant technical personnel, bearing industry is a typical example.

The backwardness of China's bearing industry technology is closely related to the severe shortage of technical personnel. The technical structure of bearing enterprises in China has a widespread fault in the age structure. The leading cause of faults in many enterprises’ professional engineers and technicians is the failure of personnel training in colleges and universities. This is because the bearing specialty of the original seven or eight engineering colleges was cut down and merged under the pretext of so-called development “wide-caliber professional”. In the field of integrated mechanical engineering, it became a subject (professional course) attached to the major of mechanics, and the number of graduated majors in bearings was drastically reduced.

Now the bearing specialty of Henan University of Science and Technology has become the only “only child” in the country. Up to now, the university has trained nearly 2,000 undergraduates and master students for the national bearing industry. The vast majority of these students have become the technical backbone of the bearing industry. Henan University of Science and Technology is hailed by the industry as "the Whampoa Military Academy of China's bearing industry." However, the university's bearing specialty only provides more than 60 graduates each year, far from meeting the needs of thousands of bearing factories across the country.

Strengthen bearing research and education is imminent Japanese bearing giant NSK, its headquarters has as many as 1800 R & D personnel, this is China's bearing counterparts can not imagine. For many laymen, bearing is a kind of simple structure. Is it necessary to have so many R&D personnel? In fact, the bearings we see in daily life are low-end bearings with low technical content, while the high-end bearing technology is not comparable to the low-end bearings.

Lu Bingheng, an academician of the Chinese Academy of Engineering, believes that high-end bearing R&D involves a series of technical problems such as materials, grease and lubrication, manufacturing, design, bearing manufacturing equipment, testing and testing, as well as contact mechanics, lubrication theory, tribology, fatigue and damage, and heat treatment. Basic research and cross-disciplines such as material organization.

Lu academician's remarks indicate the extreme complexity of high-end bearing technology, which is very difficult. This also shows that it is necessary to set up an engineering specialty for bearings. While a comprehensive, wide-caliber undergraduate mechanical engineering major has learned dozens of hours of bearing class, but such a short academic time, only learned to cover the profound knowledge of the fur, such as such undergraduate students into the bearing The industry is almost equal to starting from scratch. It is too time-consuming. The competent working time is too long. The employer must also spend a lot of time and effort on training its bearings into professional knowledge.

As mentioned above, the short plates of high-end bearings do not only exist in the field of aero-engines. In the field of high-precision machine tools, high-speed railways, instrumentation and other fields, such short boards still exist, and only we increase the development of high-end bearings. With regard to human, financial, and material resources, China can achieve a fundamental shift from a big bearing country to a strong bearing country.
