Six big bearing fault

Jiaxing mainly precision miniature deep groove ball bearing motor bearing for the main business: the company mainly produces sales of high quality, high precision, low noise of the miniature deep groove ball bearing, products are rated: Z2 group. Z3 group. Level precision of the Z4 group, : P2, P4, P5, P6, widely used in the machine, shredder, computer fan, paper, toys, entertainment tools, electric tools, water pumps, sports machinery, machinery and equipment, and so on. Bearing welcome friends from all walks of life come to visit and guide and negotiate. Let us win-win a better future hand in hand together! 1) Breaks the characteristics of the bearing fatigue flake is bearing raceway. This is due to the decrease of strength of bearing steel particles, particles that cause peeling off from the roll channel. After peeling off the bearing surface is rough, it will produce noise and vibration. When the bearing under the condition of normal load and work to achieve its life expectancy, will produce normal fatigue damage. This form of damage can be expected, it is because of the metal under the continuous action of load and damage. Transmission within the bearing hole to set set, if the size of the bearing hole is too small, or loss of circle, the early may lead to fatigue damage. Heavy boring the hole on the shell should be especially careful. After hole boring and partial shell will cause the installation error of axis, that will also cause bearing early fatigue damage. Therefore, the precision of the boring equipment should be higher. 2) Bad lubrication caused by poor lubrication of the bearing damage characteristic is: flake discolouration and raceway of bearing parts, it is possible that damage of cage. Bearing the cause of the damage is not only due to the height of oil level is too low, also may be due to the lubricating oil containing impurities, grade is not appropriate, and of different lubricating oil to mix. 3) Indentation indentation is refers to the bearing raceway shoulder or small gap at the bottom of the 2 it may be due to the bearing due to its improper installation or removal methods. If the bearing on the bearing of a seat, beating another seat or pressure, will cause the indentation. When tapping bearing with a hammer and chisel, in addition to generate indentation, may cause dust cover, cage, and the damage of the baffle ring. Using the right tools such as wheel, can avoid the damage of the above. 4) Micro vibration wear due to vibration, on the bearing outer ring rolling bearing holes on the machining of the grave. This effect is called the micro vibration wear. 5) Pollution damage due to dirt into the gearbox casing or bearing with impurities in the process of maintenance storage into the bearing bearing caused the pollution damage. Bearing master WeChat: 2966884113 bearing pollution damage of raceway, ball or roller on the indentation, scratch or rust or corrosion pitting and bearing parts. In addition, if the lubricating oil containing fine particles ( Such as abrasive powder) Therefore, should be in accordance with the provisions, the cycle of change the transmission oil, to slow down the pollution of the bearing damage. 6) Inside and outside the circle of different heart if installing a transmission, the input shaft and the flywheel of the guide bearing hole, the positioning on the input shaft bearings is likely different heart inside and outside the circle. When the roller cage and dust cover damage may occur. When looking for the reason of different heart, should first check the clutch shell and installation surface and coaxial degree of the guide bearing, at the same time check whether there is sundry interfuse, installation location is correct.
