Angular misalignment is unavoidable in most applications of rolling-element bearings. The goal of this study is to examine the effects of angular misalignment on the running torque of angular contact ball bearings. A computational method to calculate the running torque of misaligned angular contact ball bearings was introduced. Then, the effects of angular misalignment, along with radial and axial loading, on the running torque of angular contact ball bearings were investigated for two representative preloading methods: constant-force preload and constant-displacement preload. The simulation results showed that (1) the angular misalignment, irrespective of bearing loading, significantly increases the angular contact ball bearing running torque when the constant-displacement preload method was implemented, and (2) the angular misalignment has an insignificant effect on the angular contact ball bearing running torque when the constantforce preload method was adopted. Furthermore, an extensive simulation was performed to examine the effect of loadinduced angular misalignment on the running torque of angular contact ball bearings implemented in a geared shaft system. The simulation results showed that the radial load-induced angular misalignment requires additional running torque to the actual rotor-bearing systems, especially when using the constant-displacement preload.

“…Savas xkan and Maleki 15 performed experiments to investigate the friction and wear properties of Zn-25Al-based bearing alloys. Brecher et al 16 investigated the effects of cage friction in the high-speed spindle bearings and proved that the frictional torque caused by cage friction could not be neglected in the analysis of bearing friction resistance. With respect to the investigations on the bearing with defects, Shaha et al 17 carried out a lot of experiments and indicated the correlation between the frictional torques and the different size defects.…”

Radial load is of great significant influence on friction characteristic and fatigue life of rolling bearings. A frictional torque analysis was performed on the radially loaded SKF-6205 deep-groove ball bearings. The frictional torque formula was proposed as the sum of the frictional torques caused by elastic hysteresis, elastic hydrodynamic lubrication, differential slip, spinning friction of balls, friction between the balls and the cage pockets, and friction between the cages and the guiding lands. The experiments were carried out with the bearing with lubrication and the other one without lubrication under different radial loads and rotational speeds. In order to avoid the frictional torque measurement errors caused by the unequal length of arms, a positive-negative test method is employed to test bearing frictional torque. The experimental results showed that the frictional torque caused by radial loads played a leading role in all the frictional torque components of the bearing. Ultimately, a special theoretical model of frictional torque for deep-groove ball bearings was verified through comparing with the experimental results and SKF torque model. A reasonable correlation exists between the experiment results and the theoretical model.
