HYDRODYNAMIC BEARING Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention may be used in thrust and support bearings with hydrodynamic lubricating layer for machines and, particularly, for supports of rolling mills characterized by high peripheral velocities and specific loads. Hydrodynamic bearing has pockets made on one of operating surfaces which form hydrodynamic lubricating layer. All pockets are arranged only in part or through the full area of layer where pressure increases along length of layer. Pockets starting with feeding one from which lubricant is delivered to layer are separated from one another along length of layer by means of partitions provided with sharpened vertices terminating in sealing edges. Invention provides for increase in minimum thickness of lubricating layer and for enhanced carrying capacity of bearing. EFFECT: reduced heat emission and wear. 5 cl, 8 dwg
