Dynamics of Roller Bearings of Gas Turbine Engines under Hydrodynamic Friction

The paper considers a method for calculating the skidding in cylindrical roller bearings under contact hydrodynamic friction and confirms its compliance with experimental data on skidding at various values of radial load and radial clearance. Dependences of the skidding value of bearings 2672934 and...

Zusammenfassung:The paper considers a method for calculating the skidding in cylindrical roller bearings under contact hydrodynamic friction and confirms its compliance with experimental data on skidding at various values of radial load and radial clearance. Dependences of the skidding value of bearings 2672934 and 1032930 on the radial load and bearing clearance, which are critical for the occurrence of seizing, are determined.
