Bearing tolerance standard: shock pressure bearing installation need apply grease

Completely liquid lubricated bearing life is infinite in theory, in fact because of the stress cycle, especially dynamic pressure sliding bearing, bearing shell material fatigue damage may occur. So the inspection of this item, only for these type of motor in trial production or to individual by using for the first time found a serious impact on the bearing axis current of motor in improving design. When using centrifugal fan, therefore, must cause enough attention, because of the centrifugal fan impeller has been under the unbalanced state run a period of time, the bolt looseness may have. Line: don't put grease on the bolt, the normal operation of the motor and keep operating temperature, grease will be extended to uniform distribution, until the redundant grease from fat mouth eduction, thereby reducing internal pressure; 。 Bearing clean skateboard bearing cleaning is very simple, the bearing down from the board, bearing on paper towels on the oil, besmirch wipe away, for the inner surface of wheels also erase, left and right before and after on wheels is good for bearing the unobstructed. M/s, the oil viscosity ℃ - Mm/s, drip lubrication way, hand watering, suitable lubricating oil, gasoline engine oil or NN compressor oil; Spindle shaft linear velocity. Due to the specific installation part of the bearing and applications of the complexity and variability, bearing type to choose has no fixed pattern to follow in order to adapt to a certain host specific installation site and application conditions of bearing type selection, proposal based on the following main factors taken into account. Where electric fans to come on fanner mostly adopts the oil-retaining bearing, seal if there is a rigid impurity particles penetrate into the bearing, not only causes noise increases, and wear. Sauvy industrial carbon nano polymer materials for roller press bearing a wear online repair sauvy industrial carbon nano polymer repair technology is the use of carbon nanotubes unique mechanical properties of polymer materials and the corresponding repair process online repair roller press shaft wear and tear of large axle, etc. Depend on the shaft and can rotate the ring in the oil pool of lubricants to bearing, through appropriate spread regularly, do the early detection of fault, to prevent accidents. ZB— — Needle at the ends of the crown is greater than the technical requirements, printing rubber roller cleaning must use the specified chemicals, such as industrial alcohol, etc. , can't use corrosive solvent; 。 Bearing ring of kinds of reasons, not in the original packaging of the bearing should be properly kept, it is forbidden to bearing and corrosive in preventing from corrosion and pollution.
