Abstract:
The well-known solutions for the pressure distribution in the lubricating
film of a hydrodynamic journal bearing, satisfying the Reynolds
boundary conditions, show a sudden change in the pressure gradient at the
position of maximum film thickness, which is possible only if the lubricant is
added precisely at this position. Since the pressure develops smoothly
because of hydrodynamic action, a correction in the Reynolds boundary
conditions is proposed and a new solution for the pressure distribution is
obtained. The steady state characteristics of a hydrodynamic journal bearing
using the new boundary conditions are compared with the well-known
characteristics using the Reynolds boundary conditions.
