The effect should be support; that is, the literal explanation is used for the bearing; the bearing heater is only a part of its effect; the support is essentially capable of bearing the radial load. It can also be understood that it is used to fix the shaft. It is the fixed shaft that can only complete the transformation; and the manipulation of its axial and radial movement. The result of the motor without the bearing is that the foundation can not work. Because the shaft can move in any direction; while the motor is working, the demand shaft can only be changed. In theory, the effect of the transmission cannot be completed; not only that; the bearing also affects the transmission; in order to reduce this effect, it is necessary to complete the outstanding smoothness on the bearings of the high-speed shaft; some bearings themselves have been smooth; called pre-smooth bearings; Most of the bearings need to have smooth oil; when working at high speed; because conflict does not only add energy; more terrible is that it is very simple to damage the bearing. The statement that turning the conflict into a rolling conflict is one-sided; Something called a sliding bearing.
It is a fixed mechanism in the machine. When other parts move relative to each other on the shaft; the mechanism used to adhere to the middle of the shaft and manipulate the movement; it is called a bearing.
In Chinese ancient books; bearing heaters have long been described about the structure of axle bearings. 1279; China's Guo Shoujing invented the geography of the instrument; its effect is similar to modern thrust roller bearings. 1772; British C. Vallo portrayed the production of ball bearings; and installed it on the mail truck for trial use. 1794; British P. Worth obtained the patent for ball bearing. In the middle of the 19th century; Europe followed the bearing materials, smoothing agent and mechanical manufacturing process; the beginning has a relatively complete sliding bearing. 1881; Germany's H. R. Hertz announces a paper on the contact stress of ball bearings. On the basis of Hertz's results; Germany's R. Strebeck, A of Sweden. Pamgren and others have carried out a lot of experiments; dedication to the theory of rolling bearings and the calculation of the fatigue life of bearing heaters. 1883; N of Russia. P. Petrov used Newton's viscosity law to account for bearing conflicts; the same year British B. When measuring the conflict coefficient of the vehicle bearing, Thor added the oil film pressure in the bearing of the submarine bearing; and measured the pressure distribution curve of the oil film. 1886; O of the United Kingdom. Renault made a mathematical analysis of Thor's discovery; derived the Reynolds equation; from then on, laid the foundation of the fluid dynamics smoothing theory. After the 1960s; the elastic fluid dynamic pressure smoothing theory is gradually experienced; according to this theory, the rolling bearing is used to make life The number is large for addition.
