To enhance the intelligent monitoring capabilities of wind turbine main shaft bearings, this study investigates the thermomechanical performance of embedded slot structures within the bearing outer ring. A 3D finite element model is developed for a typical single-row tapered roller bearing. Simulation results indicate that under steady-state thermal and combined load conditions, the overall temperature rise and maximum thermal deformation of slotted bearings are nearly identical to those of non-slotted ones. Local thermal responses are primarily concentrated at groove corners and fillet transitions. Proper control of slot depth and location ensures functional sensor integration while maintaining structural thermal stability. The proposed model provides guidance for the design of the intelligent bearing body structure.

摘要

To enhance the intelligent monitoring capabilities of wind turbine main shaft bearings, this study investigates the thermomechanical performance of embedded slot structures within the bearing outer ring. A 3D finite element model is developed for a typical single-row tapered roller bearing. Simulation results indicate that under steady-state thermal and combined load conditions, the overall temperature rise and maximum thermal deformation of slotted bearings are nearly identical to those of non-slotted ones. Local thermal responses are primarily concentrated at groove corners and fillet transitions. Proper control of slot depth and location ensures functional sensor integration while maintaining structural thermal stability. The proposed model provides guidance for the design of the intelligent bearing body structure.
