Contact Analysis for the Critical Shoulder Height in Angular Contact Ball Bearing

Tribology Transactions, 2011
A 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 ...

Slip Measurement in an Angular Contact Ball Bearing

Journal of Lubrication Technology, 1983
An experimental method for ball-race slip measurement that includes a method for determining the geometry of an assembled bearing from easily and accurately measured parameters is presented herein. Slip measurements taken with four fluid lubricants are discussed in terms of quantity, structure, bulk properties, and degradation.

Multi-Body Contact Dynamics Analysis of Angular Contact Ball Bearing

Applied Mechanics and Materials, 2013
The 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 ...

Motion of a Ball in Angular-Contact Ball Bearing

A S L E Transactions, 1965
The 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.

Precessional slip in an angular contact ball bearing

Wear, 1982
Abstract 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.

Basic Speed Ratio of an Angular Contact Bearing

Journal of Lubrication Technology, 1980
A characteristic number, the basic speed ratio for an angular contact ball bearing, is defined and shown to be 1) accurately measurable; and 2) dependent on ball-race coupling. Some measurements of basic speed ratio are discussed in terms of kinematic equivalence, and compared with predictions obtained from a computer simulation.

Angular-Contact Ball Bearing Optimization Study.

1995
Abstract : Ongoing studies have indicated that advanced engines will be required to operate at higher temperatures and increased rotor speeds. The object of this project was to find the optimum internal geometry for a high speed, hybrid thrust bearing, which produces minimum heat generation.

Effect of race conformities in angular contact ball bearing

Tribology International, 2016
Abstract 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, 2016
The 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 ...
