摘要： The invention relates to a compressor for a heat pump cycle and/or refrigeration system cycle, said compressor having a housing and a rotor that is rotatably mounted about an axis of rotation. The housing is at least partly arranged on the circumference of the rotor and the rotor comprises at least one hub and at least one vane arranged radially on the exterior of the hub. The vane is designed to convey a principal fluid stream and the rotor comprises a shroud band arranged radially on the exterior of the vane, said shroud band being at a radial distance from the housing. A bearing structure is provided radially on the exterior of the shroud band, said structure being designed to create a bearing fluid stream between the shroud band and the housing in order to form a fluid dynamic bearing for supporting the rotor in the housing.

摘要： Disclosed are a hydrodynamic bearing structure(10) for bearing a cooling fan(3) and a method of assembling the same. The hydrodynamic bearing structure(10) comprises a housing(20), a hydrodynamic bearing(30), a rotation shaft(40), a thrust member(50) and a bottom plate(24). The hydrodynamic bearing(30) is mounted in an accommodating space(21) within the housing(20) The rotation shaft(40) is disposed through a rotation shaft hole(31) of the hydrodynamic bearing(30). The thrust member(50) is disposed on an end portion of the rotation shaft(40) and accommodated between a bottom surface of the hydrodynamic bearing(30) and a top surface of the bottom plate(24). A plurality of guiding grooves(51) are disposed in a surface of the thrust member(50), so that an oil layer applied with pressure is formed on the surface of the thrust member(50) to maintain stable rotation of the rotation shaft(40) and reduce the deflection and vibration of the fan(3) during rotation.

摘要： Die Erfindung betrifft einen Rotor (1) einer Turbomaschine. Der Rotor besteht zumindest aus einer Welle (2) und einem Laufrad (4, 5). Der Rotor (1) wird durch Axiallager (6, 6') geführt. Aufgabe der Erfindung ist es, bei einer Überlastung der Axiallager (6, 6') ein Anstreifen der Beschaufelung (13) eines Laufrads (4) an der Gehäusewand (14) der Turbomaschine zu verhindern. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Rotor (1) als zusätzliches axiales Führungselement mindestens einen Druckkamm (10, 10') aufweist. Dabei ist das Spiel (S K , S K ') zwischen den Druckkammflächen (17, 17') und den Anlaufflächen (11,11') größer, als das Spiel (S L , S L ') der Axiallager (6, 6'). Dadurch wird bewirkt, dass im Normalbetrieb die axiale Führung durch die Axiallager (6, 6') bewerkstelligt wird. Erst bei einer Überlastung der Axiallager (6, 6') übernimmt der Druckkamm (10, 10') die axiale Führung.

摘要： An exemplary thrust collar for a turbocharger includes a substantially annular body that includes an axis of rotation, a bore, opposing end surfaces where one of the end surfaces is substantially normal to the axis of rotation and capable of seating a back end of compressor wheel, and a surface disposed in the bore where the surface is substantially normal to the axis of rotation and capable of seating a surface of a turbocharger shaft. The axial distance between the end surface for seating a back end of a compressor wheel and the surface disposed in the bore for seating a surface of a turbocharger shaft is selected to improve balancing of a rotating assembly. Various other exemplary devices, systems, methods, etc., are also disclosed.

摘要： An ECS system (10) includes a RAM air fan (RAF) system (76, 78) downstream of a respective heat exchanger in the relatively high temperature RAM exhaust The RAF (76, 78) includes a RAF electric motor (80) such that the RAF (76, 78) is driven at a speed independent of an ACM (26) which reduces generated noise and increases overall operating efficiency. A fan rotor (102) is completely supported by hydrodynamic foil journal and thrust bearings (88, 90, 92) which permits effective operation of the RAF (76, 78) downstream of the respective heat exchangers in the relatively high temperature RAM exhaust As the RAF (76, 78) is driven by the RAF electric motor (80) the RAF (76, 78) is installed in the ECS system as a self contained system such as Line Replaceable Units (LRUs).

摘要： A two-stage vapor cycle compressor (10) includes a first stage impeller (20), a second stage impeller (21) situated adjacent to the first stage impeller, an electric motor (30) running on a pair of foil bearings (18,19), a thrust disk (16) including two foil bearings (17) and being positioned between the second stage impeller and the electric motor, and a compressor housing (40) enclosing the first and second stage impeller and the electric motor. A refrigerant vapor (27) compressed by the first stage and second stage impeller flows through an internal passageway (26) formed by the compressor housing and cools the foil bearings (17,18,19) and the electric motor (30). The compressor may be a gravity insensitive, small, and lightweight machine that may be easily assembled at low manufacturing costs. The two-stage vapor cycle compressor may be suitable for, but not limited to, applications in vapor compression refrigeration systems, such as air-conditioning systems, for example, in the aircraft and aerospace industries.
