Larger models of ball bearings or cylindrical roller bearing under purely radial load and low speed operation, due to the centrifugal force of the rolling small impact load-free area in the rolling will roll cage or road noise. But as the speed increases, this noise will disappear. On the rolling control method for impact sound: appropriate reduction of radial clearance, reasonable structure and material cages for SKF bearings with compliance.
Creak and its control method for SKF bearings creak cylindrical roller bearing can happen on all occasions of the harsh metal sound, mostly in the larger models of grease lubrication SKF bearings, and deterioration of the base oil are more likely to occur in the grease, oil lubrication does not happen almost.
In addition, the more vulnerable in the winter, when under purely radial load, prone to big occasions in a radial clearance, and with different model sizes of SKF bearings, in the context of a specific speed prone, both continuous and intermittent. External ring road, take the special processing methods can prevent creak appears, select the SKF bearings if necessary, or appropriate reduction in radial internal clearance of the SKF bearings, using high performance greases and improve go with SKF bearings, mechanical rigidity.
SKF bearings calculation method for fatigue life estimation method of Cham and test two
(1) calculated according to the formulas and calculation rules set out by SKF bearing fatigue life calculation of fatigue life, calculate the total transfer values provided for inner ring or shaft washer turn (outer ring or washer is fixed at this time), the total transfer values.
In accordance with the provisions of the standard test method for rolling bearing fatigue life test procedures, using performance meets the requirements imposed by a method of testing machine, fatigue life test sampling for SKF bearings, obtained from experimental data processing of the actual test of life, namely for this batch of participants were represented by SKF bearing SKF bearing fatigue life.
Lubrication of rolling bearing fatigue life test procedures are fully maximize the inhibiting factor of wear of rolling bearings, the use of enhanced loads and SKF bearing fatigue factors of speed to an enhanced test method for fatigue life.
SKF bearings calculation of fatigue life and fatigue life test is mutually reinforcing, corresponds to the results of both have plenty of sex.
But reality in the, as on each a specific of using occasions, are extraction enough number of SKF bearing for life test, to validation by selected SKF bearing whether suitable, this in economic Shang, and time Shang and labor Shang are is is vast of, so SKF bearing life of test method just in is necessary or important of situation Xia only using, in most situation Xia, used standard of life calculation method to estimated SKF bearing of using life, has enough degree of can dependency.
