A combined model of calculating the durability of aircraft engine high speed rolling bearings

Resumo

Based on analyzing the operating conditions for high speed rolling bearings of aircraft engines in a medium of low viscosity fuel components, we substantiated a combined model of calculating the bearing life with respect to two criteria of efficiency, namely, the contact fatigue resistance and wear resistance of their working surfaces. An algorithmic procedure and special features of calculating the durability with respect to these criteria were shown.
