Slipping characteristics of cylindrical roller bearings with multiple defective rollers

Measurement Science and Technology
Abstract The dynamic interaction among multiple defective rollers in cylindrical roller bearings (CRBs) would lead to the complex vibrations of bearings and slip behavior of rollers. Compared with raceway defects, roller defects involve a more intricate contact process, which has often been oversimplified in previous studies. However,

Fatigue life of cylindrical roller bearings

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2016
This paper dealt with the fatigue life of cylindrical roller bearings with several significant error sources that may occur during installations. A four degree-of-freedom quasi-static model for cylindrical roller bearings was developed, which took into account potential error sources such as angular misalignment, axial offset, and radial clearance ...

On the Geometrical Imperfections in Cylindrical Roller Bearings

Journal of Tribology, 1988
Computer simulations of the dynamics performance of roller bearings, as obtained by the computer code ADORE, are used to model the infuence of race out-of-roundness, race taper and centrality of land on partly crowned rollers. Both oil and solid lubricated high-speed roller bearings are considered and the overall performance parameters, such as ...

Measurement of Roller Speed in a Cylindrical Roller Bearing Using a Laser Anemometer

Journal of Lubrication Technology, 1978
A technique for measuring roller speeds in cylindrical roller bearings using a modified laser anemometer has been developed. The technique described does not require any mechanical interference with the roller and cage geometries, and is suitable for high speed testing.

Influences of roller diameter error on contact stress for cylindrical roller bearing

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2014
The rollers of rolling bearings usually have certain geometrical error in actual machining process and, in the past, the mechanics analysis and computation of rolling bearing did not take into account the influences of this error in general. A cylindrical roller bearing is taken as the research object in this paper and a calculating model has been ...

Investigation of the dynamic local skidding behaviour of rollers in cylindrical roller bearings

Proceedings of the Institution of Mechanical Engineers, Part K: Journal of Multi-body Dynamics, 2019
Skidding has a great influence on the reliability and the life of rolling element bearings. The previous research of bearing skidding mainly focussed on the gross skidding of bearings under severe conditions. However, the local skidding of rolling element also exists and cannot be ignored when bearing normally runs at steady state.

On the Frictional Instabilities in a Cylindrical Roller Bearing

Tribology Transactions, 1990
Computer simulations of a high-speed cylindrical roller bearing, as obtained by the computer code ADORE, are used to correlate bearing performance to the frictional behavior at the roller/race and cage contacts. It is shown that an optimum traction-slip relation at the roller/race contacts may be determined to produce minimum race wear and heat ...

Influence of roller defect and coupled roller–inner–outer race defects on the performance of cylindrical roller bearing

Proceedings of the Institution of Mechanical Engineers, Part K: Journal of Multi-body Dynamics, 2019
In the present study, a novel mathematical model is developed for the deformation between roller and races of cylindrical roller bearing using the effect of tilting and skewing of roller due to thrust load, radial deflection due to normal load, radial internal gap, and individual defect on roller as well as coupled defect on all races and roller. Also,
