Cone bearing, needle roller bearing which size ball bearing

Bearing bearing function and categories: the function of the bearing is a supporting shaft and the shaft rotational parts to keep its rotating accuracy, the load, but also to reduce the relative rotation between parts caused by friction and wear. R, choosing proper materials and components for gear pump has reasonable clearance and cooperation in running, the wear resistance is an important performance index of the relevant material, A, oil seal oil is also A common cause of scrap material should be chosen so good oil seal, in processing and assembling at the same time pay attention to the oil seal and with the bushing is strong. In hot and cold processing difficult to change; Carbide strip, essence and carbide sample liquid chromatography, the carbide crystal forging, rolling and is broken into small pieces, and along the rolling direction into a zonal distribution; Carbide mesh, steel forging or rolling cooling process, the cooling speed too slow, lead to separation into mesh distribution along the grain boundary carbides. Part lists the centripetal bearing delta DMP, delta DMP limit value, the standard stipulated in the bearing outer ring of single surface on the deviation of the average diameter of DMP tolerance zone is zero, as shown in figure. Inspection items are as follows: installation location bearings after installation, the first test whether running parts and fixed parts touching one another, lubricating oil can flow to flow into the bearing, seal device and axial fastening device installation is correct. Some manufacturers use in electric lubrication system can not work normally after manual fatliquoring, or to save oil consumption, fatliquoring, often appear day added to the bearing end cover with oil overflow. Transfer of a small motor end bearing lateral, sometimes with waveform spring, pressure bearing outer ring, in order to reduce the axial bearing clearance work, reduce the motor vibration and noise when running. Craft formula of heat treatment is heavy, decided to product high quality, I do training to customers, continuously to the customer to instill a view: the bearing is not a parts, is a system. & #; Rolling bearing the basic production process as a result of the rolling bearing type, structural type and tolerance grade, technical requirements, material and batch is different, the basic production process is not entirely the same. Because circulating oil can take away heat, cooling the bearing, therefore method is suitable for high speed bearing parts, this method is suitable for high speed and high temperature lubricating bearing parts. Extend the fatigue life, bearing installation method, because of the bearing structure, cooperate, conditions vary, and as much as the axis of rotation, so the inner circle need interference fit, other: also have internal bearing, or to prevent rust and corrosion effect, lubrication methods: bearing lubrication method, divided into grease lubrication and oil lubrication. MIL- L - Is the turbine oil with specifications, is I type turbine oil, the engine also typically about cl rate per hour will be based on the oil lubricant is lost to the atmosphere.
