FIELD: energy.
SUBSTANCE: invention relates to power engineering. Bearing support of two-shaft gas turbine engine containing the roller bearing arranged between rotors shafts of low and high pressure, oil supply cavity under the inner ring, oil supply holes made in the inner ring of the bearing, separator, aligned along the outer ring, at that, one or several radial oil outlet grooves of arbitrary profile are made on race tracks of inner and outer rings.
EFFECT: invention enables to substantially reduce the effect of oil wedge on rollers and rings of roller bearings, allows to reduce operating temperature with reduction of required amount of cooling oil, as well as allows to increase the bearing life.
