Study of the influence of ring misalignment in rolling bearings on frictional torque and the fatigue life of supports

Abstract

The influence of ring misalignments on the torsional characteristics and fatigue life of rolling bearings was investigated. It was shown that ring misalignment increased frictional torque in rolling bearings, especially with the radial and axial forces. Ring misalignment in the radial-thrust bearings has a controversial influence on fatigue life of supports. Fatigue life increases at small misalignments angles and decreases with an increase in the misalignment angle.
