Main Failure Forms of Main Bearings of Aero-Engine
The main bearing is the main working part of the aero-engine,and its role can be compared to the heart of the engine.Due to the harsh working environment of the main bearing of the aero-engine,the high speed and heavy load,and the contact force of the long term repeated action and so on,so it is very easy to cause fatigue,cracks,spalling,indentation,fracture,adhesion,bums and so on,and eventually will make the bearing to be blocked and jammed,resulting in the failure of the engine bearings.Once the main bearing fails,it will bring serious or catastrophic consequences to the engine.The main failure forms of main bearings of aero-engine are fatigue spalling,cracks and fractures,wear,corrosion and rust,slippage and scuffing,indentation and scoring,large carbide,dimensional changes,etc.
