摘要 |
The aerodynamic foil bearing in the form of a radial or axial thrust bearing, includes a rotor and a stator including a support designed to support, facing the rotor, a lift device including: a plurality of evenly distributed elastic foils fixed by a fixing edge to a surface of the lift device facing the rotor; rows of ventilation orifices passing through the lift device and opening between a free edge of each elastic foil and the fixing edge of the next foil, wherein the support includes a cavity having grooves extending under the rows of ventilation orifices and at least one circular groove intersecting the grooves and supplied with a stream of pressurized cooling gas to distribute same so as to cool the underside of each foil and provide a supply of fresh gas above the next foil to compensate for gas losses at the ends of the bearing. |
