Abstract:
The moving track of journal bearing changes with the time in the condition of dynamic loading. The force balance equation of journal bearing is established, and the generalized Reynolds equation, the oil film thickness equation of spiral oil wedge journal bearing under dynamic loading are gained, which is based on axial inertia force, bearing capacity and dynamically loading. By finite difference method, Euler method and Reynolds boundary condition, the generalized Reynolds equation and force balance equations are solved simultaneously, the periodic moving track of journal bearing at different times is solved. The results show that the circumferential pressure, axis displacement, axis velocity, axis acceleration velocity of journal bearing change periodically as time goes. The influence of dynamical loading on pressure distribution of oil film and axis locus is analyzed.
