Lubrication of Angular Contact Bearings

Journal of Mechanical Engineering Science, 1970
In angular contact bearings the motion of the ball on the race involves both rolling and spinning. Recent work provides theories of the generation of a lubricant film, by hydrodynamic mechanisms, for each of these motions considered in isolation. By comparison of these theories, and using knowledge of the kinematics of bearings, it has been possible ...

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 ...

Thermally Activated Seizure of Angular Contact Bearings

A S L E Transactions, 1967
Equations have been developed relating friction-power to bearing element temperatures for the particular case of prelubricated or lightly lubricated ball bearings. An expression is derived for the change in relative dimensions of an angular contact bearing, as determined by the temperature gradient across the bearing.

Fatigue Life Analysis for Angular Contact Ball Bearing with Angular Misalignment

Journal of the Korean Society for Precision Engineering, 2016
Angular 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.

Ball motion in angular contact bearings

Wear, 1968
Abstract The nature of the frictional forces and moments applied to an angular contact bearing ball is examined in terms of slip, pivoting, spin and precession. Experimental methods for determining these quantities are given, together with results which indicate that the ball is retainer-controlled for pivoting, and race-controlled for slip.
