Fan bearing box: what are the consequences of 7309 bearing if damaged

So often the whole shafting is installed in the thimble and form a component, the structure of the installation, bearing the inconvenience, round nut, is used to adjust more troublesome, but support span bigger, better rigidity. Ball rolling bearing so for bearing detection, it is very important, analytical direct contact with the outer ring of bearings and wheel part mainly play a supporting role. According to the direction of load bearing, bearing can be divided into the centripetal bearing ( Bear radial load, also known as the radial bearing) The thrust bearing ( Carry axial load) And centripetal thrust bearing ( Bear radial and axial load at the same time, also known as the radial thrust bearing) 。 Outer ring outerrin - Methyl amino acetonitrile g race, on the surface of the bearing ring, outer ring lock mouth coun - Methyl amino acetonitrile terboredouterrin - Methyl amino acetonitrile g a shoulder removal of all or part of groove type ball bearing outer ring. Tapered roller bearing inside diameter and the roll neck using loose fit, install and disassemble very convenient, but sometimes caused by loose fit slide creep, inner diameter often have spiral groove processing. The perspective of their classification, lubrication system design, should make the location of the high pressure spray nozzle lies between inner ring and maintains a center, and through the centrifugal effect to race to oil. PY company's inspection personnel have found kiln reducer high speed shaft tubing in low temperature and final confirmation and block the serious hidden trouble, so as to avoid a major accident. The elastic deformation of rolling bearings is small, can need not consider in most mechanical, but in some machinery, such as spindle, bearing rigidity is a important factor that should be chosen as a cylinder and circular cone roller bearings. Two dimensional tolerance is: single bearing (inside diameter ds） And the outside diameter ( Ds） The deviation of ( △△d, d) ； Bearing plain surface average diameter ( dmp） And the outside diameter ( Dmp） The deviation of ( △dmp,△dmp) 。 Velvet, felt complete clean oil, placed correctly; D, refitted and adjustment after check all parts meet the requirements, will be within the bearing after daub grease into the wheel hub. About bearing on the rubber roller bearing in the high-speed operation of the machine, bearing wear is obvious, coupled with the operators of bearing maintenance do not pay attention at ordinary times, the wear is more severe. Cage abnormal loading, causing wear failure are the major factors of lubricant or the lack of lubricant, lubrication method is wrong, there are internal grinding grain into the bearing, heavy load, etc.
