2020-3-21 · The prediction of transient dynamic behavior of high speed cylindrical roller bearings is necessary to evaluate new design concepts and design changes in existing bearings. Many phenomena, such as cage-roller impacts and roller-flange impacts, which limit bearing life or affect bearing per-
Get PriceA nonlinear dynamics analysis mathematical model for the high-speed cylindrical roller bearing was built up. Dynamic performance parameters were got by Newton - Raphson method . The rotational velocity regularities of rollers were analyzed at different radial loads. The distribution of minimum oil-film thickness and contact load between rollers and ...
Get PriceHarris developed a quasi-dynamic model of cylindrical roller bearings in 1973 which removed the assumption of raceway control theory. There are also some achievements gotten by quasi-dynamic models,,,. With the strict requirements of accuracy, a simple dynamic model of bearings were developed.
Get Price2019-7-30 · When cylindrical bearings operate at a high speed, they generatevibrationsandnoise. eprincipalforces,which drive these vibrations, are time varying nonlinear contact forces, which exist among the various components of the bearings: rings, rollers, and cage. In the last decades, a lot of e orts have been devoted to studying the stability
Get Price2021-2-1 · This paper proposes a dynamic model to investigate the vibration response of a cylindrical roller bearing considering skidding. This model considers the frictional forces and the contact forces between rolling elements and races simultaneously. The interactions between the frictional forces and the dynamic responses of rolling bearing when skidding ...
Get PriceConsidering cage dynamics of high-speed cylindrical roller bearing, the values of cage guidance gap and eccentricity are crucial factors. From the point of view of the manufacturers, the very small cage guidance gap is difficult to obtain owing to the material (brass) of the cage used in high-speed bearing.
Get Price2018-11-10 · This paper presents a nonlinear dynamic differential equations of high-speed cylindrical roller bearing considering the impact of roller dynamic unbalance. The cage vibration characteristics are investigated as a function of roller dynamic unbalance, structure parameters and working conditions.
Get Price2017-12-1 · The phenomenon on the cage dynamic characteristics of high-speed cylindrical roller bearing has attracted a serious attention from academia. Based on the bearing dynamics, a dynamic cage model was developed by Walters, and the cage dynamic characteristics were investigated.
Get PriceThe paper contains a detailed analysis of dynamic behavior of cylindrical roller bearings for unbalanced rotor conditions due to speed variations and internal clearances. The system behaves nonlinearly due to various reasons such as stiffness and damping at the contact points (due to Hertzian contact force between rollers and races), radial internal clearance, and speed associated with unbalanced rotor force.
