Effect of race conformities in angular contact ball bearing
Tribology International, 2016Abstract The determination of race conformity of ball bearing is mainly based on the classical fatigue life theory; however, besides the fatigue life, skidding may also become the main concern due to high frictional heating in high-speed application; therefore the strategy of race conformity determination should be changed accordingly.

Thermo-mechanical analysis of angular contact ball bearing
Journal of Mechanical Science and Technology, 2016The thermal-mechanical character, which is difficult to ensure because of the lack of a corresponding theory and tool, has a significant effect on the dynamics of bearings. It even leads to a sudden failure of bearings in a working situation. In this research, a thermal deformation model was established, based on the analysis of temperature effect on ...

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

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 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

Angular Contact Ball Bearings for a Rear Axle Differential
SAE Technical Paper Series, 2003<div class="htmlview paragraph">In passenger car axle differentials, axially preloaded tapered roller bearings have been used exclusively since their rigidity and life are sufficient for this application. In real life applications, the bearing preload during transmission life is reduced due to wear in the contact between the roller and the rib ...

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 ...

Contact Analysis for the Critical Shoulder Height in Angular Contact Ball Bearing
Advanced Materials Research, 2012A numerical method to determine the shoulder height in the angular contact ball bearing using 3D contact analysis is proposed. The load analysis of a ball bearing was performed to calculate the distributions of internal loads and contact angles of each rolling element.

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 ...

EHD Modeling of Angular Contact Ball Element Bearings
2015The objective of this work is the study of the dynamic of angular contact ball element bearings considering the elastohydrodynamic lubrication. A computational model was built to foresee the dynamic behavior influence on the lubrication condition of those components.
