Abstract

The invention provides a roller bearing system for an aero-engine, which includes a roller bearing system inner ring, a cage and a roller bearing system outer ring, the cage is installed on the roller bearing system inner ring and the roller bearing system outer ring. Between the outer rings of the roller bearing system, at least a pair of annular retaining lugs are provided on the outer surface of the cage at intervals, and the inner circular surface of the outer ring of the roller bearing system is provided with mounting holes. A blocking column is installed in the installation hole, and the blocking column prevents the retainer from moving in the axial direction. The present invention is equipped with an anti-deflection and movement device of the cage, which can ensure the stable operation of the cage when the bearing installation error occurs or some abrupt working conditions occur.

Description

Technical field [0001] The present invention relates to aeroeiro roller bearings, and more particularly to a roller bearing system for an air engine. Background technique [0002] In the prior art, the aviation engine develops towards the large thrust ratio, high reliability and other directions. The roller bearing operating conditions as the engine key components have become more demanding, aerospace engine roller bearings due to the holder deflection, the cage shaft axial swift or the slope of the roller slip and the bearing inside and outside the outer circle Talking, wear, etc. often occurs, which in turn affects the working state of the roller bearing. Therefore, it is essential for the aerospace engine roller bearing system, especially regarding the optimization design of the holder. [0003] Aviation engine roller bearings are key components that are normal for aerospace engines that are arranged between the engine journal and the bearing seat for supporting the rotor. As ...
