The Influence of Housing and Shaft Configurations on the Performance of Rolling Bearings By Finite Element Analysis

Determination of rolling bearing deflection accurately is of great importance for machine tool applications. The methods most widely available in literature for calculating rolling bearing deflection are based on the simplifying assumption of rigid races which retain their circular shape on loading. In reality the bearing tracks, together with the housing and shaft which support them, are also subject to deformations, which may be significant when compared with those of the contact areas and of the rolling elements alone.
