HYDRODYNAMIC AXIAL SUPPORT

摘要

FIELD: high-velocity supporting units of turbines and compressors. SUBSTANCE: hydrodynamic axial support includes step bearing with smooth working surface and pivot fitted on shaft. End surface of pivot is provided with spiral grooves directed at acute angle relative to sense of rotation of shaft. Groves are narrowing from center of pivot towards its periphery; they are smoothly connected with circular groove on end surface of pivot. EFFECT: enhanced reliability. 2 dwg øøø1
