Do you know Ball bearings history?

China is the world’s earlier invention bearing one of the countries in the Chinese classics, the axle bearings on the structure has long been documented. And data from the archaeological perspective, China’s most ancient structure with a prototype of the modern rolling bearings, appeared in 221 ~ 207 years BC (Qin Dynasty) of this Yongji County, Shanxi Province, Xue Cliff Village.
After the founding of New China, especially since the 1970s on, a strong push in the reform and opening up, the bearing industry entered a new period of rapid development of high quality.
In the seventeenth century, the British design and manufacture of ball bearings C. Vallotton, and installed the trial in the mail car and the British made ball bearings P. Wirth a patent.
Eighteenth century in Germany published the HR Hertz contact stress on ball bearing papers. Build on the achievements in Hertz, R. Germany, Sweden, Glenn A. Pam, who conducted a large number of experiments, bearing on the development of design theory and contributed to the fatigue life calculation.
Subsequently, the NP Petrov of Russia apply Newton’s Law to calculate the bearing viscous friction. Leo O. Renault UK has been the discovery of mathematical analysis, Reynolds equation is derived, from laying a hydrodynamic lubrication theory.
In fifty years the founding of the Chinese bearing industry has made remarkable achievements.
The early form of linear motion ball bearings, is a skid plate placed behind a row of wood. This technique may be traced back to the time to build the Great Pyramid of Giza, though there is no clear evidence. Modern linear motion bearings using the same kind of works, but sometimes replaced by roller ball. The first sliding and rolling bearings are made of wood. Ceramics, sapphire, or glass are also used, steel, copper, other metals, plastics (such as nylon, bakelite, teflon, and UHMWPE) are widely used.
From heavy vehicle axle and spindle to the precision watch parts, many occasions require rotating bearings. The simplest is the sleeve bearing swivel bearings, it is just a folder in the bush between the wheel and axle. This design was subsequently replaced rolling bearing is cylindrical roller with a lot of the original bushing replacement, each rolling like a single wheel. First put into practical use of the rolling bearing with a cage clockmaker John Harry is worse than 1760 for the production of H3 timing meter of the invention.
Nano lake in Italy found a Roman ship, found earlier instances of ball bearings. The wooden ball bearings are used to support the rotating desktop. The ship was built in 40 BC. Leonardo da Vinci around the year 1500 is said to have been of a ball bearing described. Ball bearings of various immature factors, there is a very important point is that the ball between the collision, causing additional friction. But you can put the ball into a small cage to prevent this phenomenon.
The 17th century, Galileo on the “fixed ball”, or “cage ball” ball bearing did the first description. But then for a long time, the bearing is installed on the machine has not been achieved. The first patent was on the ball channel Carmarthen in 1794 Philip Vaughan received.
In 1883, Friedrich Fischer proposed the use of suitable production machine grinding the same size, roundness of the ball exactly the idea. This laid the bearing industry to create an independent basis. “Fischers Automatische Gußstahlkugelfabrik” or “Fischer Aktien-Gesellschaft” letter combinations later became the first mark, in the July 29, 1905 Registration.
1962, FAG bearing has been modified and the trademark still in use today, and in 1979 became an integral part of the company.
In 1895, Henry Timken designed the first tapered roller bearings, three years later obtained a patent and the establishment of The Timken Company.
In 1907, SKF bearings plant gentle warm Qwest designed the first modern self-aligning ball bearings.
