Cylindrical bearings, double orifice bearing seat

& gt; All kinds of bearing axial stiffness contrast size quite a thrust bearing axial stiffness is about angular contact ball bearings and tapered roller bearing axial stiffness of two times, thrust cylindrical roller bearing axial stiffness big, screw support with bearing axial stiffness between taper roller bearings, thrust cylindrical roller bearings. Angular contact ball bearing is a common kind of bearing type in order to make everyone Angle contact ball bearing with better and more understanding, tell everyone common kinds of angular contact ball bearing installation respectively, back to back, face to face, and arrange the installation method of series, according to the use of different areas may choose a different approach to the installation of bearing better and safer. Does not ethanol water clean bearing, dust does not impurities; , want to clean containers of lubricating oil or grease, at ordinary times should be sealed, there should be no dust, iron and other sundry, in order to avoid damage to the bearings. After u remove the universal joint cross shaft needle bearing a thorough cleaning, remove all remaining grease ( Available water or in gasoline cleaning) After the min - in the gear oil Methyl amino acetonitrile - lmin - Methyl amino acetonitrile, can use. In order to explore the residual amount of investigation and lubricant, after sampling, to better cleaning bearing, if found damage and bearing abnormal situation, find out the reason, formulate countermeasures. Bearing stiffness can look it up in the product manual, the reason of this kind of shaft voltage is due to the uneven distribution of motor internal magnetic flux, especially in some less polar logarithmic motor. In fact, the high speed turbine in order to reduce the friction with the floating bearing, can only transfer torque, friction to a low, angular contact bearings are only used for other moment under axial thrust is mainly composed of thrust bearing. Close, small make up found on the Internet has a lot of car owners to repair or have to understand, this is a good phenomenon, but also can let oneself only for car maintenance and maintenance, car xiaomao is look at myself, can, professional maintenance problems but I hope you still want to believe that maintenance of the master of good, according to the information listed, for example, such as clutch with sound, ten have happened release bearing problem, believe that maintenance teacher spend less waste of money. To measure the size of the rotor and bearing the parts separately, and make corresponding records, specific steps are as follows: to measure the rotor shaft neck diameter: select multiple position measurements, take the average, compared with the drawing design value, should be consistent. Denier bearing characteristic frequencies or close to the bearing characteristics of the frequency spectrum, should determine bearing fault, and then according to the size of amplitude, can make trend analysis or arrange maintenance. If bearing for interference fit is mounted on the bearing hole, bearing outer ring is fixed, shell hole block shoulder its outer end face and the shell hole blocking shoulder face is on tight, installation is correct, also can examine thickness gauge. Improve assembly and method of use, bearing a irregular and uneven 'scrape' sound, the sound is due to the bearing inner into the iron filings, sand and other impurities.
