Abstract

The invention relates to an insert support device of a shaft bush, belonging to the technical field of sliding bearings of mechanical products and being an elastic device supported and arranged between the bearing bush and a bearing seat. The insert support device comprises a bolt, a support block connected with the bearing bush through the bolt, an elastic cushion block and a plurality of gaskets. The insert support device has the advantages that: due to the adoption of the device, a support part can be radially regulated and can freely swing so as to be convenient for centering regulation of the bearing bush; ad due to the adoption of the elastic part, inherent or externally-forced vibration of the system is subjected to elastic damping, thus an oil film is protected, when a rotor generates disturbance, the instability of the oil film is effectively reduced, the amplitude of the rotor in the whole operation speed range is reduced, the stability of the system is improved, and the service life of the bearing bus is prolonged.

Description

technical field

[0001] The invention belongs to the technical field of sliding bearings of mechanical products, and in particular relates to an insert supporting device of a bearing bush. Background technique

[0002] In the existing rotor-bearing systems of rotating machines such as steam turbines and blowers, an insert device is usually provided between the bearing pad and the bearing seat, including bolts, support blocks connected to the bearing pad by bolts, and several gaskets. Its main function is to adjust the center elevation of the rotor by reducing or increasing the shim. However, due to the relatively high rigidity of the system in the existing rigid support device, when the rotor is subjected to external force or the bearing seat is forced to vibrate, it cannot release the dynamic instability force caused by the deformation of the oil film, which often leads to friction between the rotating shaft and the bearing pad. The relative vibration increases, affecting t...
