This article extends the force analysis of the single rolling element in the whole double row tapered roller bearing to the establishment of a global static equilibrium equation. And further analyzes the position relationship between the roller and the raceway after deflection under overturning torque. Based on non-Hertz line contact theory and bearing force balance equation, a numerical analysis model for the contact stress of the raceway in a double row tapered roller bearing is proposed; To verify this model, a local finite element model of bearing contact was established based on ANSYS to obtain the stress distribution of the raceway. The results show that the stress calculation model for wind turbine spindle double row tapered roller bearings under overturning torque proposed in this paper has good simulation accuracy.

摘要

This article extends the force analysis of the single rolling element in the whole double row tapered roller bearing to the establishment of a global static equilibrium equation. And further analyzes the position relationship between the roller and the raceway after deflection under overturning torque. Based on non-Hertz line contact theory and bearing force balance equation, a numerical analysis model for the contact stress of the raceway in a double row tapered roller bearing is proposed; To verify this model, a local finite element model of bearing contact was established based on ANSYS to obtain the stress distribution of the raceway. The results show that the stress calculation model for wind turbine spindle double row tapered roller bearings under overturning torque proposed in this paper has good simulation accuracy.
