Abstract

The purpose of the invention is to provide an aviation engine bearing supporting component and an aviation engine. The aviation engine bearing supporting component provided by the invention comprisesan installation seat, the installation seat is provided with an installation surface, the installation surface is part of a spherical surface, the aviation engine bearing supporting component furthercomprises a positioning ring, a connection part, a first position-limiting ring and a second position-limiting ring, the first position-limiting ring and the second position-limiting ring are in contact with the installation surface spherical surface correspondingly to be used for supporting one bearing correspondingly, the positioning ring is fixedly arranged on the installation surface, the connection part is used for fixedly connecting the first position-limiting ring, the second position-limiting ring and the positioning ring into a whole, and the positioning ring is used for bearing overload force to be separated from the installation surface. According to the aviation engine bearing supporting component, because the positioning ring is clamped, flying-off will not appear, therefore,the aviation engine bearing supporting component has high safety. The aviation engine provided by the invention comprises the aviation engine bearing supporting component, therefore, the aviation engine has high safety.

Description

technical field [0001] The invention relates to an aeroengine bearing support assembly and an aeroengine. Background technique [0002] According to the requirements of airworthiness regulations (FAR33.74, FAR33.94), commercial aircraft engines must ensure that the occurrence of FBO events (fan blades flying out) will not lead to catastrophic consequences. In order to ensure the safety of the aero-engine after the FBO incident, the traditional method is to increase the structural strength of the components on the engine force transmission path, such as the rotor support structure, load-bearing casing, installation system, etc., to increase its stress reserve margin , to ensure that key components will not fail under FBO loads. However, this will increase the weight of the engine, which is not conducive to the weight reduction design. [0003] In recent years, with the improvement of engine thrust, the diameter of fan blades has become larger and larger, and the unbalanced ...
