Abstract

The computational fluid dynamics (CFD) method was used to establish the model of internal self-controlled restrictor hydrostatic bearing with discrete oil pocket area. The pressure field and velocity filed were calculated with different supply pressures and eccentricity ratios by the numerical simulation. The simulation results indicate that the load capacity of film increases with the supply pressure growing. The pressure in the lower oil pocket is larger than that in upper one. The flow also increases with supply pressure growing, but little relationship with the eccentricity. The bearing at the diameter of 200mm is designed and manufactured. The operation tests demonstrate that the pressure and velocity plot in the pocket is similar to the simulation one.
