The development history of roller bearing
China is one of the countries that invented roller bearing earlier in the world. In ancient books, there have been records about the structure of axle bearings. According to archaeological relics and materials, the oldest bearing with the rudiment of the modern roller bearing structure appeared in Xuejiaya Village, Yongji County, Shanxi Province in 221 ~ 207 BC (Qin Dynasty). After the new establishment, especially since the 1970s, under the strong impetus 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, the British C. Varlow designed and manufactured roller bearing, and installed them in the mail car trial and the British P. Worth took out a patent on roller bearing. At the end of the eighteenth century, H.R. Hertz in Germany published a paper on the contact stress of roller bearing.
On the basis of Hertz's achievements, Germany's R. Stribeck, Sweden's A. Palmgren and others conducted A large number of tests, which contributed to the development of the design theory of roller bearing and the calculation of fatigue life. Then,
N.P. Petrov of Russia calculated bearing friction using Newton's law of viscosity.
In the 17th century, Galileo Galilei made the earliest description of a "fixed ball" or "cage ball" roller bearing. But in a long time afterward, the installation of bearings on the machine has not been realized.
The first patent for a ball channel was obtained by Philip Vaughan of Camasson in 1794.
In 1883, Friedrich Fischer proposed the use of suitable production machines to grind steel balls of the same size and accurate roundness. This laid the foundation for the creation of independent bearing industry.
Roller bearing is an important basic part of all kinds of mechanical equipment. Its accuracy, performance, life and reliability play a decisive role in the precision, performance, life and reliability of the main engine. In mechanical products, bearings belong to
High-precision products, not only need the comprehensive support of mathematics, physics and many other disciplines but also need material science, heat treatment technology, precision machining and measurement technology, numerical control technology and effective numerical methods and powerful functions
Computer technology and many other disciplines serve for roller bearing, so the roller bearing is a product representing the national scientific and technological strength.
