Abstract

The invention discloses a mouse cage elastic support metal rubber damper. The mouse cage elastic support metal rubber damper comprises an elastic support module; the elastic support module comprises abracket, a rotating shaft inserted in the bracket, a bearing sleeving the rotating shaft, and a mouse cage elastic support for supporting the rotating shaft and the bearing; the mouse cage elastic support comprises an elastic support mounting edge fixedly connected with the bracket, an elastic strip arranged on the side of the elastic support mounting edge, and an elastic support bearing base arranged at the end of the elastic strip for mounting the bearing; an end cover is arranged at the end of the bracket; a cavity structure module and metal rubber for providing support damping to a rotorsystem are arranged around the elastic support bearing base; the cavity structure module, the inner end surface of the end cover, the inner wall surface of the bracket and the outer wall surface of the elastic support bearing base form a closed cavity; and the metal rubber is arranged in the closed cavity. In the mouse cage elastic support metal rubber damper, the main support damping is providedto the rotor system through the metal rubber, so that the stable linear support rigidity in the wider extrusion deformation range is guaranteed.

Description

technical field [0001] The invention relates to the technical field of elastic support of a high-speed rotor system, in particular to a metal-rubber damper supported by a squirrel-cage spring. Background technique [0002] The development of high-speed rotating machinery such as high-performance and high-reliability aero-engines requires the rotor to have excellent damping and shock absorbers to ensure that the vibration of the rotor system is effectively controlled when it is close to the critical speed and passing through multiple critical speeds. Squeeze film damper (Squeeze film damper, SFD) has been widely used in high-speed rotating machinery such as aviation and aerospace engines due to its simple structure, small size, light weight, low cost, and remarkable vibration reduction effect. However, SFD is a kind of nonlinear damper. At high speed and large unbalance, its oil film stiffness increases nonlinearly with the increase of journal eccentricity, and it is easy to ...
