Abstract

The invention discloses an elastic supporting structure of an engine rotor transition section, which relates to the field of rotor supporting of aero-engines and gas turbines. The elastic supporting structure mainly comprises a bearing seat, an exhaust casing and a flexible transition section arranged between the bearing seat and the exhaust casing, wherein the flexible transition section is usedfor connecting the exhaust casing to the bearing seat, the inner mounting edge of the flexible transition section is fixedly connected to the outer wall surface of the bearing seat, and the outer mounting edge is fixedly connected to the inner wall surface of the exhaust casing. The flexible transition section structure can also be used as an elastic supporting element, and the rigidity of the transition section can be adjusted by changing the material and structure of the flexible transition section, so that the combined rigidity of the bearing and the casing is changed, the dynamic performance of the whole rotor system is changed, the optimal supporting rigidity is realized, and the stability of the rotor system is improved.

Description

technical field [0001] The invention relates to the technical field of rotor support for aero-engines and gas turbines, and relates to a support structure for a transition section of an engine rotor, in particular to an elastic support structure for an S-shaped transition section, which can be used as a buffer element at the connection between a bearing and a casing, and can be used according to The structural design flexibly adjusts its support stiffness to provide optimal rotor support stiffness, and reduces rotor vibration response through oil film damping, improving the stability of the aeroengine rotor-support system. Background technique [0002] The rotordynamic design of aeroengine is one of the core technologies of aeroengine design, and the vibration characteristics of the rotor-support system are the guarantee of high performance and high reliability of aeroengine. With the continuous improvement of the working speed of the aeroengine rotor system and the limitati...
