Dynamic simulation of cylindrical roller bearings

, 2014
In this work, a three-dimensional dynamic simulation model for cylindrical roller bearings is developed based on multi-body-simulation software SIMPACK and programming language FORTRAN. The aim of this work is to build a universal program to calculate the dynamic behavior of cylindrical roller bearings.

Effects of Misalignment in Cylindrical Roller Bearings on Contact between Roller and Inner Ring

IOSR Journal of Engineering, 2013
Misalignment of roller has remarkable effects on the life span of bearings. Taking a cylindrical roller bearing N1015 as a research object, the contact stress between the roller and the raceway is studied by means of ANSYS in order to determine reasonably the angle of misalignment of roller.

Profile Modification for Tilting Coupled with Skew Roller in Cylindrical Roller Bearing

Jixie chuandong, 2017
In order to reduce the edge effect,the tilting and skew effect of the roller. Using the Eyring Non- Newtonian fluid model,the parabolic modification function is applied to a finite line contact thermal EHL model. The pressure is solved with multilevel method and the temperature is calculated with sequential column sweeping technique.
