In the qin dynasty had the old rolling bearing structure. The British inventor in the design and manufacture of the spherical bearing at the end of the 17th century, to run the test on the coach. Britain's P. Taken out a patent on ball bearings. The German H at the end of the eighteenth century. R。 Hertz published papers about ball bearing contact stress. In Hertz achievement, on the basis of Germany's R. Terry baker, A Swedish. PAM glen et al. , a large number of trials, the development of the design theory and fatigue life calculation of rolling bearing. Subsequently, Russia's N. P。 Petrov Newton's law of viscosity are used to calculate the bearing friction. Britain's O. Renault mathematical analyses of thor's findings, the Reynolds equation is derived, from then on, laid the foundation of hydrodynamic pressure lubrication theory. Since the reform and opening, in combination with the development of foreign culture, bearing industry enters a period of high quality fast.
