Ball-Ball Load Carrying Capacity in Retainerless Angular-Contact Bearings
Journal of Lubrication Technology, 1982Load carrying capacity between the balls in a retainerless bearing, theoretically zero, is shown experimentally to be large enough to allow for full complement operation.

The effect of preload of angular contact ball bearings on durability of bearing system
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2014Angular contact ball bearings are commonly used in such situations when you need to reach high bearing stiffness. However, a significant stiffness increase can be achieved only through the introduction of preload to the angular contact bearings. The purpose of this paper is to present a method for assessing the effect of preload of the angular contact ...

The influence of the circulation of the balls in an unlubricated angular contact thrust ball bearing
Wear, 1969Abstract In the paper 1 by this author the effect of the circulation of the balls in an angular contact thrust ball bearing was thought to consist solely of the centrifugal force. However, there will also be a gyroscopic effect due to the fact that, in general, the axis of rotation of a ball in the bearing changes with time. In the present note this

Contact Analysis for the Critical Shoulder Height in Angular Contact Ball Bearing
Tribology Transactions, 2011A method to determine the shoulder height in an angular contact ball bearing using a 3D contact analysis is proposed. The load analysis was performed by calculating the distributions of internal loads and contact angles for each rolling element. From the results of the bearing load analysis and the contact geometry between the ball and raceways, 3D ...

Multi-Body Contact Dynamics Analysis of Angular Contact Ball Bearing
Applied Mechanics and Materials, 2013The 3-D multi-body contact dynamics simulation model was built by ADAMS base on the Hertz contact theory and multi-body contact dynamics, which considered the dynamics relationship among the ball, ring and cage of the bearing. Considering the clearancesfrictions and loads, results that contained deformation and displacement of the bearing, trajectory ...

The analysis of the motion of the balls in an unlubricated angular contact thrust ball bearing
Wear, 1968Abstract In the present paper the motion of the balls in an unlubricated angular contact thrust ball bearing is analysed. The material is presented in order of increasing complexity. First, the case of identical contacts in slowly rotating bearings is considered, and it is found that the balls roll with pure spin.
