GAS TURBINE WHEEL SUPPORT Russian patent published in 2017 - IPC F02C7/00 

FIELD: engine devices and pumps.

SUBSTANCE: wheel support of a gas turbine engine (GTE) comprising of an outer and inner shaft between which a radial roller bearing with outer and inner rings is installed and a nut. The outer shaft is provided with a radial shoulder formed on the inner diameter of the latter, in contrast to the known one, it is provided with two ring elements, installed between the outer ring of the radial roller bearing and the outer shaft, with an axial clearance with respect to each other. The contact surfaces of the ring elements and the outer ring of the roller bearing are spherical. The ring elements are fixed relative to the outer shaft by a radial shoulder and a nut and axially spring-loaded by means of a split ring, mounted between the nut or the radial shoulder of the outer shaft and the adjacent ring element. The contact surfaces of the split ring and the ring element are conical with respect to the longitudinal axis of the support.

EFFECT: increase in the reliability of the support by eliminating the swash of the bearing rings and reducing the contact stresses between the rollers and rings, hence increasing the bearing capacity by means of a full contact of the rollers with the rings.
