Варианты расчета эквивалентной нагрузки роторных подшипников качения в газотурбинных двигателях

Abstract

The work discusses options for calculating the equivalent loads in the rotary bearings of GTE and their estimated durability. The bearing in high pressure turbine family of PS-90 engines shows options of calculations that have the highest accuracy in comparison with operational data. Has been noted that the calculation method should be improved taking into account the limit contact endurance of the materials of bearings for a number of cycles with loading more than 100000000.
