On the Causes and Effects of Roller Skewing in Cylindrical Roller Bearings
Tribology Transactions, 1998Cylindrical roller bearings which support thrust and/or moment loading in addition to predominant radial loading have flanges on both the inner and outer rings to accommodate the thrust loading carried by the rollers. The roller thrust loading causes roller tilting and friction moments about the rotating axis perpendicular to both the bearing and ...

On the Lubricating Mechanism of Roller Skew in Cylindrical Roller Bearings
Tribology Transactions, 2013Skewing is the motion of a roller as it turns about an axis normal to the roller–race interface in cylindrical roller bearings. With a special coordinate transformation technique, complete numerical solutions for the finite line elastohydrodynamic lubrication (EHL) contact formed between a roller and races were obtained to investigate the lubricating ...

Misalignment Effects in Cylindrical Roller Bearings
Applied Mechanics and Materials, 2014All cylindrical-rollers profiles exhibit severe discontinuities in the end chamfer zones; the ZB profile includes two more at the common points of the crowned radius and straight line, Fig. 1.

Cage Instabilities in Cylindrical Roller Bearings
Journal of Tribology, 2004A six-degree-of-freedom model was developed and used to simulate the motion of all elements in a cylindrical roller bearing. Cage instability has been studied as a function of the roller-race and roller-cage pocket clearances for light-load and high-speed conditions.

Fatigue life of cylindrical roller bearings
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2016This 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, 1988Computer 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 ...

Effect of Varying the Number of Rollers on Dynamics of a Cylindrical Roller Bearing
Volume 8: 26th Conference on Mechanical Vibration and Noise, 2014In present paper, nonlinear dynamic model has been developed for cylindrical roller bearings. The Hertzian contact theory is used to derive a two degree of freedom model which considers nonlinearity due to clearance. The nonlinear dynamic behaviour of cylindrical roller bearing has been studied with varying number of rollers supporting load.

An Experimental Investigation of Cylindrical Roller Bearings Having Annular Rollers
Journal of Lubrication Technology, 1976This study deals with an experimental investigation of a cylindrical roller bearing having annular rollers. Comparisons are made with a solid roller bearing having the same configuration and dimensions. Radial deformations and load distribution between rollers are measured under static load and compared with numerical solutions.

Misalignment Problems in Cylindrical Roller Bearings
SAE Technical Paper Series, 1970<div class="htmlview paragraph">In the application of cylindrical roller radial bearings where cumulative assembly tolerances or load deflection insure a significant skewness between inner and outer race center lines, careful design and manufacturing methods are required to provide reliable performance.
