In terms of its function, it should be a support, that is, it is used to support the shaft literally, but this is only part of its function. The essence of support is to be able to bear radial loads. It can also be understood that it is used to fix the shaft. The china bearing manufacturers suppliers‘s bearing quick, easy and optimal automatic selection is included. It is to fix the shaft so that it can only achieve rotation, while controlling its axial and radial movement. A motor won’t work at all without bearings. Because the shaft may move in any direction, and the motor is required to only rotate when it is working. Theoretically speaking, it is impossible to achieve the function of transmission. Not only that, but the bearing will also affect the transmission. In order to reduce this influence, good lubrication must be achieved on the bearing of the high-speed shaft. Some bearings themselves have been lubricated, called pre-lubricated bearings, and Most of the bearings must have lubricating oil, which is responsible for the high-speed operation, which not only increases energy consumption due to friction, but also easily damages the bearings. It is one-sided to say that sliding friction is converted into rolling friction, because there is something called a sliding bearing.
lubricating
The purpose of lubricating rolling bearings is to reduce the internal friction and wear of the bearing, prevent burning and sticking; prolong its service life; discharge frictional heat, cool down, prevent the bearing from overheating, and prevent the lubricating oil itself from aging; it also prevents foreign matter from invading the inside of the bearing, or prevents rust and corrosion The effect.
lubrication method
Bearing lubrication methods are divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to select a lubrication method suitable for the conditions of use and the purpose of use. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication has the advantage of simplifying the structure around the bearing. The advantages and disadvantages of grease lubrication and oil lubrication are compared. When lubricating, special attention should be paid to the dosage. Whether it is oil lubrication or grease lubrication, too little lubrication will not fully affect the life of the bearing, and too much lubrication will produce large resistance and affect the speed.
