The History Of Bearings In China

wallpapers Environment 2020-12-22

China is one of the earliest countries in the world to invent rolling bearings. In ancient Chinese books, there are long records about the structure of axle bearings. According to archaeological relics and materials, China’s oldest bearing with the prototype of a modern rolling bearing structure appeared in Xuejiaya Village, Yongji County, Shanxi Province, from 221 to 207 BC (Qin Dynasty).

 

After the founding of New China, especially since the 1970s, under the strong promotion of reform and opening up, the bearing industry has entered a new period of high-quality and rapid development.

 

At the end of the seventeenth century, British C. Wallo designed and manufactured ball bearings, and installed them on mail trucks for trial use, and British P. Worth obtained a patent for ball bearings. At the end of the eighteenth century, German H.R. Hertz published a paper on the contact stress of ball bearings.

 

On the basis of Hertz's achievements, R. Stribeck in Germany, A. Palmgren in Sweden and others have conducted a large number of experiments, which have contributed to the development of rolling bearing design theory and fatigue life calculation. Subsequently, Russia’s N.P. Petrov applied Newton’s law of viscosity to calculate bearing friction.
