Needle roller bearing import: manual release bearing is easy to replace

The classification of the rolling bearings of rolling bearing type many, if used to withstand the load, the different direction can be divided into the centripetal bearing, thrust bearing and angular contact bearings. After the eccentric sleeve installation is firm, socket head cap screw locking eccentric sleeve. Increase the carry axial load capacity, calculate and mixed right amount according to the bearing chamber wear sauvy SD materials, the material evenly coated in repair parts closely; 。 Low friction coefficient, steel rolling body excessive rolling solid pollutants, due to plastic deformation, will be in the race and rolling elements have bump is formed on the edge of the indentation. Sn - snap ring groove diameter Methyl amino acetonitrile aprin - Methyl amino acetonitrile roovediameter snap ring groove of the diameter of the cylindrical surface, sn - snap ring groove width Methyl amino acetonitrile aprin - Methyl amino acetonitrile roovewidth snap ring groove of axial distance between two end face. Bearing noise bearing inner relative motion between the parts of the friction and vibration, or rotational part imbalance ( Reflected in the shaft under the condition of different heart) , relative motion between the parts of impact, etc. , will result in bearing noise. & emsp; & emsp; & emsp; & emsp; The problems existing in the & amp; emsp; & emsp; A certain power plant #, # unit electric feed water pump motor bearing box, after a long running appear oil leakage phenomenon, loss of turbine oil is relatively serious, fill oil frequently, feed water pump output affected, the environment has also been set the degree of pollution. Its forming reason: keep the frame material is usually made of low strength of lightweight materials, combined with the isolation of the lintel roller size smaller, so under the effect of external force, the cage could produce plastic deformation. Such fault processing unit must be combined with maintenance, gear pump technology reason to protect the reasonable gap between before and after the gear end cover, processing and assembling of the gear pump is very important. Equipping matchedstack will or more of the rolling bearing a predetermined set of features, usually by the preload or clearance or manufacturing, and installation methods in accordance with provisions in the. Dyed point distribution, demanding ° - in the center of the bearing - every square centimeter in ° Angle Points so far, shoulds not be too little or too much; Otherwise, need crapping, after shaving with a white cloth dipped in alcohol clean tile face and neck, repeat the above research method, make the bearing shell dyed point scraping the thinner, the more more more, until it meets the requirements. & emsp; & emsp; The accident reappearance and cause analysis & amp; emsp; & emsp; In the accident, unit are in a state of full power, generator bearing damaged, card before death, when bearing fault, first the damaged bearing cage, bearing between the inner and outer ring friction heat is serious, this is interference fit, due to the rapid thermal expansion, caused between the bearing inner ring and generator shaft resistance is reduced, and generate mutual sliding, friction produces a lot of heat.
