Dynamic modelling of slip in a wind turbine spherical roller main bearing

Forschung im Ingenieurwesen, 2023
This paper considers the problem of the dynamic modelling of macroslip in spherical roller bearings. By revisiting the fundamental physics which drive these systems, potential issues in existing models have been identified. Furthermore, in pure rolling conditions it was found that governing differential equations become “stiff”, requiring the use of ...

Modeling and Dynamic Analysis of Spherical Roller Bearing with Localized Defects: Analytical Formulation to Calculate Defect Depth and Stiffness

Shock and Vibration, 2016
Since spherical roller bearings can carry high load in both axial and radial direction, they are increasingly used in industrial machineries and it is becoming important to understand the dynamic behavior of SRBs, especially when they are affected by ...

Finite Element Analysis for Cylindrical and Balling Bearings Under Static and Dynamic Loads A-review paper [PDF]

SVU-International Journal of Engineering Sciences and Applications
The ball bearing is a mechanical gearbox's most important component. It connects the roller to the inner and outer rings and hangs from the rotator to support the revolving parts. This technique allows for the transmission of both electricity and motion.

Simulation of Subcritical Vibrations of a Large Flexible Rotor with Varying Spherical Roller Bearing Clearance and Roundness Profiles

Machines, 2020
In large rotor-bearing systems, the rolling element bearings act as a considerable source of subcritical vibration excitation. Simulation of such rotor bearing systems contains major sources of uncertainty contributing to the excitation, namely the ...
