How to solve the essential significance of FAG bearing noise

Reduce the rolling road sound can reduce the noise of the whole machine. Impact sound of the rolling body and control method of a large model of ball bearings or cylindrical roller bearings under purely radial load and low speed operation, due to the centrifugal force is small, is not in the load zone will impact rolling roll cage or road noise. But with the increase of rotational speed, the noise will disappear. On the rolling control method for impact sound: appropriate reduction of radial clearance, the use of reasonable structure and materials to keep the FAG bearing frame compliance.
A calculation method and test Cham branch two estimation methods of fatigue life of FAG bearings
( 1 ) the FAG bearing fatigue life calculated in accordance with the provisions of formula and calculation rules as the calculation of the fatigue life, the total numerical rules to rotate to the inner ring or shaft ( the outer ring or ring is fixed ) numerical total rotation.
In accordance with the provisions of the standard test methods of rolling bearing fatigue life test procedures, in the use of performance to meet the required for a method of testing machine requirements, sampling test of fatigue life of a FAG bearing, the actual test life obtained from the test data processing, the fatigue life is tried the FAG bearing FAG bearing the.
Rolling bearing fatigue life test Pi is the maximum inhibitory factor of wear full lubrication of rolling bearing, the load and speed enhancement to an enhanced fatigue life test method of outstanding FAG bearing fatigue factors.
Calculation method and the fatigue life test of fatigue life of FAG bearings are complementary to each other, the two results have corresponding adequate.
But in reality, such as for each specific occasions, all selected FAG bearing enough for life test, to verify the selected FAG bearing is appropriate, this is very big in the economy, time and amount of labor, so the test method of FAG bearing life only is used in a very necessary or important case, in most cases, using standard methods to estimate the service life of FAG bearings, with a sufficient degree of dependency.
