摘要： The object of the invention is to improve the film stiffness of a face seal without increasing the sealing and dam area.The improved sealing apparatus (16) has a primary seal ring (20) in the form of a nose piece. A spring (24) forces a sealing surface (28) on the seal ring into sealing contact with a seat (18) to form a face seal. A circumferential clearance seal is formed in series with this face seal by a lip (34) on the nose piece. The width of the surface (36) of the lip is substantially the same as the width of the sealing surface (28) on the face seal. Also the clearance between the surface (36) on the lip and the shaft (10) is substantially the same as the spacing between the face sealing surfaces (28 and 30) on the face seal when the shaft is rotating.The circumferential clearance seal restricts the flow of fluid from a main cavity (14) to an intermediate cavity (32) with a resulting pressure drop. The hydrostatic opening face is strongly dependent on the face seal clearance, and the desired axial stiffness is achieved.
摘要翻译：本发明的目的是在不增加密封和坝面积的情况下提高面密封的膜刚度。改进的密封装置（16）具有鼻部形式的主密封环（20）。弹簧（24）迫使密封环上的密封表面（28）与座（18）密封接触以形成面密封。圆周间隙密封件通过鼻片上的唇缘（34）与该面部密封件串联形成。唇缘的表面（36）的宽度与面密封件上的密封表面（28）的宽度基本相同。此外，当轴旋转时，唇缘上的表面（36）与轴（10）之间的间隙基本上与面密封件上的面密封表面（28和30）之间的间隔相同。周向间隙密封限制流体从主腔（14）到中间腔（32）的流动，产生压力降。流体静力开启面很大程度上取决于表面密封间隙，实现了所需的轴向刚度。

摘要： A method for designing bearings, of improved performance, the load-bearing surfaces of which feature micropores about 2 to 10 microns deep and, preferably, aspect ratios on the order of 7 to 20. The hydrodynamic pressure distribution of a suite of bearing surfaces with different micropore geometries and densities is modeled numerically. The load-bearing surfaces of the bearings are fabricated with micropores having the optimal density and geometry determined by the numerical modeling. Conical micropores may be created by single laser pulses, with the pore size and shape controlled by controlling the laser beam profile, the laser beam power, and the optical parameters of the focusing system.

摘要： A hydrodynamic, non-contacting end-face seal for a rotary machine comprises a rotor mounted on the machine shaft and a ring-shaped stator facing the flat and smooth surface of the rotor at a short distance. The stator encloses the machine shaft, is eccentrically positioned in respect of the rotor center, and is urged towards the rotor surface by a helical spring. The surface of the stator ring is shaped to form a circular rim separated from the rotor surface by a very small gap of varying width, and the space enclosed by this rim is raised to a higher pressure than the surroundings by the hydrodynamic action of the surface velocity of the rotor on the liquid in the machine, by making the gap width as follows: the gap width between rotor and stator is of a mechanically permissible minimum in all points of the rim at which the velocity vector of the rotor surface extends from the inside of the rim to the outside, and the gap width is larger in all points of the rim at which the velocity vector extends from the outside to the inside. The gap width is changed, in accordance with pressure conditions in the machine by action of the helical sprin

摘要： A lubricated hydrostatic seal comprising (a) surface regions having opposing surfaces; (b) a plurality of micropores in one or more of said surfaces having a pore geometry; and (c) a flow of fluid between said surfaces, wherein said flow of fluid past said micropores provides a lifting force between said surfaces. In a preferred embodiment, the opposing surfaces of the surface regions are nominally parallel. Nominally-parallel surfaces are simple to manufacture and are considerably less expensive than the various converging-surface configurations of the prior art. The nominally-parallel surface configuration can also be utilized in both liquid-lubricated and gas-lubricated hydrodynamic seal applications, and in hybrid-seal applications in which both hydrodynamic and hydrostatic lift are generated.
