Abstract A new model for cylindrical roller bearings, capable of deterministically handling lubrication and misalignment situations, is developed by coupling a quasi-static model and a finite line-contact EHL solver. Numerical results of internal load, pressure, and film thickness between rollers and raceways as well as bearing stiffness are obtained

An Analytical Investigation of Cylindrical Roller Bearings Having Annular Rollers
A S L E Transactions, 1967Cylindrical roller bearings with annular rollers may be advantageous in applications where weight, lubrication, and speed are major considerations in the operation of the bearing. This discussion describes an analytical technique whereby the effects of the elastic and Hertzian distortions of the hollow rollers are considered in the determination of the

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.

Lubrication of cylindrical rollers with surface corrugations
Wear, 1972Abstract The paper shows how the wavelength of corrugations on a cylindrical roller strongly influences its hydrodynamic properties. It is further shown how these properties, as the wavelength decreases, tend towards those obtained by the authors' probabilistic roughness theory.

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 ...

Slipping characteristics of cylindrical roller bearings with multiple defective rollers
Measurement Science and TechnologyAbstract 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,

Electron beam lithography on cylindrical roller
Microelectronic Engineering, 2010We developed a nano-structure fabrication technology over a cylindrical roller using electron beam lithography (EBL) and a specimen rotation apparatus. The high-resolution patterning is done on a cylindrical roller specimen and it is achieved by controlling the thickness of photo-resistance (PR) and dosage of the electron beam (EB).

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 ...
