The development history of zhaoqing city bearing manufacturer mining bearing in guangzhou

The development history of guangzhou zhaoqing bearing manufacturer mining bearing early way to linear motion bearings is put a row of wooden poles in a row of checkered plate. The working principle of the modern linear motion bearings using the same but sometimes use alternative roller ball. Simple is the rotation of the bearing sleeve bearing, it is just a sandwiched between the wheel and the axle sleeve. Then replace the design with high temperature rolling bearing, roller bearing liner using a lot of cylindrical roller instead of the original. Each roller as a separate wheels. In the 40 years BC built a Roman ship found an early example of ball bearing. In Italy that m lake: use wooden ball bearing support rotation of the desktop. I heard that leonardo Da Vinci ( Leonardo da Vinci) Painted around 1500 of the ball bearing. Among various kinds of immature factors of ball bearing, ball collide with each other and make up the additional friction is very important. But it can keep the ball in the small cage to prevent. Galileo in the 17th century, first painted with stick to frame the ball of the ball bearing. At the end of the 17th century, England's C. Wallow design and manufacture of ball bearing, and install it on the coach to stop the trial, and P of England. Worth obtained a patent for ball bearing. The clockmaker John harrison ( 约翰·哈里森) Invented in 1760 with a stick to the application of the rolling bearing, to make H3 astronomical clock. The end of the 18th century, the German H. R。 Hertz published papers about the ball bearing contact stress. According to the achievements of Hertz, Germany's R. Pamgren Stribeck, Sweden and others suspended many tests for the design of the rolling bearing theory and fatigue life calculation. Then, N. P。 Russia's petrov application of Newton's law of viscosity to calculate bearing friction. Kumar, Philip vaughn ( 菲利普·沃恩) In 1794 the first patent of fairway. In 1883, friedrich fisher put forward with suitable for consumption equipment of the same size and accurate roundness steel ball grinding, which laid the groundwork for the bearing industry. O of England. Reynold found suspended a mathematical analysis of Thor and Reynold equation is obtained, which lay the foundations for the hydrodynamic lubrication theory.
