摘要： To overcome defects in the supply of pressurized lubricant to a hydrodynamic bearing, a hydrodynamic bearing is provided that includes a stationary outer annular wall and a rotatable inner annular wall (20), extending opposite the outer annular wall so as to provide a space (22) between said walls. The outer annular wall comprises an opening for supplying pressurized lubricant to the space so as to form a film of lift fluid. The bearing includes a cavity (30) externally defined by the inner annular wall (20) and axially defined by two transverse annular walls (31A, 31B) secured to the shaft (14) and arranged on both sides of the cavity. The inner annular wall (20), comprising a fluid connection means (32) that places said wall in communication with the space (22) and the cavity (30), is arranged so as to form a lubricant supply for a transitional operational phase.
