Full ball bearings: how to realize the two-way cross roller bearing positioning

Has almost to the frequency of the ingredients, difference lies in the speed value integral into displacement values, lose part of the high frequency components, so in the rolling bearing, fan wheel, pump body, impeller and other complex mechanical vibration measurement, the use of vibration velocity values for failure analysis, because it can provide more abundant spectral information. Air bearing refers to the use of the bearing pressure air film formed between the sliding surface of deputy to the bearing load bearing, work entirely by gas membrane separation between sliding surface of vice. When using integral type bearing do swim bearing, such as deep groove ball bearing, spherical roller bearing, the installation must be allowed in the outer ring and shell holes, or inner ring and shaft adopts a loose fit, axial can swim free. Fan bearing application is very wide, we are also the role of bearing of the fan is very clear, but in the use of fan questions, also hard to avoid can meet some issues we feel innocuous, but there are some problems, but will affect the use effect of the fan, and even the service life of the fan, especially the use of fan bearing problem is more prominent in these problems. Advantage is the shaft extension end can withstand the axial load and radial load, axial can accept, do not need to preload the drive on the motor rotor of thermal expansion, big disadvantage is the noise of the machine, the bearing damage probability is higher ( Compared with the two bearing configuration) 。 B— — Contact Angle for degrees, use when installation should careful not allowed powerful punch, are not allowed to use hammer percussion bearing directly, not allowed by transfer roller pressure. Measures: check the conditions of use; Set appropriate interference and check material. To improve the installation and usage; Prevent crack friction ( Check the lubricant) ； Check around the bearing design; Cage damaged. In strict accordance with the assembly requirements for later assembly, & amp; #; Insufficient cooling cooling is usually characterized by: pipe blockage, chooses inappropriate cooler, the cooling effect is poor. The first step, the vehicle with lifting machine up, dangling the wheel and loosen the hand brake; The first step, the driving wheel, can be manually by arrive slow fast rotating wheels, check whether there is bearing noise; The first step, when the test drive wheels, launch vehicle idler wheel, to check whether there is additional bearing noise. Fat burning, engine room temperature, the gear oil inlet temperature, also after the stop rising, in addition, coupling and coupling of organic matter in carbide housings, also can produce a small amount of. Figure at the shaft bearing bearing outer ring interference fit in the case of the bearing outer ring with interference fitted to dismantle the bearing outer ring gear is the premise of the shoulder diameter of not less than the requirements of the bearing support diameter, can be used as shown in the figure below schematic drawing tools to remove the outer ring. Execution, use circular arc end tooth link is mainly must have a specialized processing equipment, this is the RR company in key technology in the development of the rotor engine during development.
