In this thesis, the effect of manufacturing errors on the running accuracy of plain journal bearings is analyzed theoretically. A derivation of the Reynolds equation is presented in fixed Cartesian coordinates using the short bearing approximation. It is assumed that form errors of journal and bearing are train of waves of sinusoidal profile.
The results for the running accuracy of the journal is given in terms of the nondimensional velocity and bearing parameters. The effect of manufacturing errors on the running accuracy becomes more predominant at larger eccentricity ratios, i.e. under conditions of heavier loading and lower velocity.
