Ball Motion Perturbation in an Angular-Contact Ball Bearing
A S L E Transactions, 1982Spectral analysis of changes in the angular velocity vector of a bearing ball can be used to follow changes in ball-lubricant-race coupling in starved operation. Simultaneous measurements of basic speed ratio confirm the changes up to and through a lubricant breakdown failure. Presented at the 36th Annual Meeting in Pittsburgh, Pennsylvania, May 11–14,

Fatigue Life Analysis for Angular Contact Ball Bearing with Angular Misalignment
Journal of the Korean Society for Precision Engineering, 2016Angular misalignment has a significant effect on the characteristics of angular contact ball bearings (ACBBs). This paper presents an analysis of fatigue life for ACBBs subjected to angular misalignment. A simulation model is developed with de Mul’s bearing model and the ISO basic reference rating life model.

Motion of Unbalanced Balls in High-Speed Angular Contact Ball Bearings
Journal of Tribology, 1990This paper reports on an experimental study of the three-dimensional ball motion of an unbalanced ball in a 50-mm bore angular contact ball bearing operating at high speeds under axial loads. One bearing ball, which was unbalanced by making a small hole in it, was magnetized and the motion of the ball was determined using Hall-elements. The bearing was

Motion of a Ball in Angular-Contact Ball Bearing
A S L E Transactions, 1965The author carried out an experimental investigation on the motion of a ball in an angular-contact ball bearing under thrust load by measuring change in magnetic flux induced by a magnetized ball. The observed data of the angular velocity of the ball and that of the cage were adequate for analyzing the kinematical condition in the bearing.

Contact trajectory of angular contact ball bearings under dynamic operating condition
Tribology International, 2016Abstract A contact trajectory model of ball bearings under the dynamic condition was developed by the means of the development of the integrated multi-body dynamics and multi-freedom kinematics with the multi-interfacial contact mechanics. Subsequently, the general methodology was employed to investigate the dynamic contact performance of ball ...

Precessional slip in an angular contact ball bearing
Wear, 1982Abstract A previously reported ball precessional motion in an angular contact bearing is analyzed. Explicit forms for ball-race slip are given, both with and without precession. Slip and entrainment velocity at ball-ball contacts in a retainerless bearing are also given, also with and without precession.
