Abstract

The experimental study of operating of sliding liquid bearing at various loads with failure of oil system for simulation abnormal mode of turbine engine gearbox is carried out. Dependencies friction coefficient of fluid bearing fr om velocity, temperature and time in the oil starvation mode is presented. The lim it values in the load mode of oil starvation is presented.

Keywords:

gas turbine aircraft engine, gearbox, sliding liquid bearings, abnormal modes, boundary lubrication, friction coefficient, materials of friction pairs.
