Recently informed the dawn of KGBAL Group, Electrical and Mechanical Manufacturing Co., Ltd. and Henan University of Science and Technology jointly developed high-performance PTFE fibers woven liner self-lubricating bearings a key technology research and application "project won the second prize of" China Machinery Industry Science and Technology Award ".

  

  Extract from the original are as follows:

  With the high-performance fiber gasket is self-lubricating bearings, a variety of extraordinary conditions in the aerospace, high-speed transportation, military equipment and other applications in the field of the continuous deepening and expansion of the failure phenomenon of an increasing number, especially bearing wear failure is most obvious on the high-end host the most destructive, leading to huge economic losses. Therefore, the bottleneck constraints of the domestic high-performance fiber pad to enhance self-lubricating bearings quality technology is urgently needed. 
  PTFE fiber woven liner self-lubricating bearings with low noise, no oil pollution, and low coefficient of friction, environmental protection and other characteristics. Therefore, the structure of that type of joint bearing design, the bonding process optimization and performance evaluation of key technologies to achieve to enhance the purpose of joint bearing life and reliability, and thus enhance the technical level of the high-end equipment. The major innovations are as follows: 
  1)quantitative description of the evaluation parameters of the PTFE fiber gasket joints bearing the bonding quality, surface peel strength and solve our country relies heavily on engineering experience to qualitatively determine the bonding quality of joint bearing liner technology, to achieve the objective of product quality evaluation.
  2)the development of pre-treatment in the PTFE fiber gasket joint bearing a bonding method, which allows the bond strength increased by 47 percent, meet or exceed the performance of similar foreign products, breaking the monopoly of foreign technology.
  3)proposed a self-evaluation of the tribological properties of lubricating bearings. The research results have been declared a national invention patents, and is currently in a real trial publicity stage.
  4)independently developed a composite swing joint bearing friction and wear tester. The machine can tilt, under the conditions of rotating composite swing friction and wear performance testing, breaking the limitations of existing single swing direction detection, the results have been authorized a utility model patent, publicity a national invention patent. The same time, independently developed a high-frequency high-torque swing joint bearing device, the oscillating frequency of the testing machine break with only a 1Hz serious defects, which greatly expand the scope of the performance test, the results have been authorized national utility model patents a. 
  5)for the first time the primary and secondary fiber woven liner joint bearing tribological properties of influencing factors, the technical means for optimizing selection of the bonding process. This method can make the product quality has been significantly improved. 
  6)reveals the correlation between the joint bearing bond quality and dynamic performance, bearing bond strength increased 47%, the dynamic coefficient of friction can be reduced by 17%, more than 20% longer wear life.
  The research results have been the dawn of the Electrical and Mechanical Manufacturing Co., Ltd. in Ningbo have been applied to enhance the performance of the company PTFE fiber woven liner use of self-lubricating bearings products. Related products have been applied: (1) batch used in Shanghai maglev rail beam damping bearings; 2 batch used in the German Mercedes-Benz heavy-duty trucks, hydraulic suspension and variable suspension; ③ been successfully applied to the German Porsche racing initiative suspension system. In addition, the research results can be applied to areas such as aerospace, heavy machinery and military equipment, has a distinct role in the promotion of Machinery Industry scientific and technological progress. Direct economic benefits in the past three years a total of 23.8 million yuan, earning foreign currency of $ 5,640,000. Indirect economic benefits to count by nearly five years, obtained more significant, reaching 900 million yuan.
