The estimation method of NTN bearing fatigue life has two methods of accounting and experiment. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
The NTN bearing fatigue life calculated by the rule formula and the accounting rule is used as the calculated fatigue life; the calculated total rotation value is the total rotation value when the inner ring or the shaft ring is changed (the outer ring or the seat is fixed at the moment).
According to the rules and regulations of the experimental method to roll the NTN bearing fatigue life test procedures); in the performance of the performance can be satisfied as a method of the various requirements of the experimental machine; a batch of NTN bearing sampling fatigue life test; from the experimental data processing The actual experimental life obtained in the test; that is, the fatigue test life of the batch of NTN bearings represented by the NTN bearing.
The fatigue life of the rolling bearing is experimentally a sufficient smoothing maximum limit to roll the wear factor of the NTN bearing. The enhanced load and speed are selected as an intensive fatigue life test method for the outstanding NTN bearing fatigue factor.
The nuclear algorithm and fatigue life test of NTN bearing fatigue life are mutually reinforcing; the results obtained by the two have satisfactory correspondence.
In fact; for each specific application, a number of NTN bearings are taken for life-span experiments; to verify whether the selected NTN bearing is suitable; this is very economical, time-consuming and labor-intensive. Therefore, the experimental method of NTN bearing life is only used in very necessary or important cases; in most cases; the standard life calculation method is used to estimate the service life of NTN bearings; Sex.
