摘要： A magnetic bearing for rapidly rotating machines (1), in particular, for turbo compressors, drag vacuum pumps, or similar, includes two bearings (3, 4), each with a stator magnetic-ring set (5, 7) and a rotor magnetic-ring set (6, 8). Movement of the rotor is damped by magnetic-ring sets (5, 6; 7, 8) arranged concentrically to each other. The stator magnetic-ring set (5 or 7) is arranged externally and the rotor magnetic-ring set (6 or 8) is arranged internally. Non-magnetic elements with good electrical conducting properties (32, 54, 55) are connected to the outer circumference surfaces of at least one part of the magnetic ring of each of the stator-side magnetic-ring sets (5, 7).

摘要： A rotor (12) is mounted in a stator (14) with radial magnetic bearings (16, 19) and with an axial magnetic bearing (40) in a contactless manner. The axial magnetic bearing (40) produces an axial magnetic field with a magnet coil (40) and a yoke iron (44) mounted on the stator (14). An axially magnetized permanent magnet (50) is provided on the rotor (12), located approxaimately axially opposite the yoke iron (44). A permanently axially magnetized compensating magnet (54) is provided on the stator (14) and arranged axially opposite the permanent magnet of the rotor (50) and polarized in the opposite direction, such that the permanent magnet (50) of the rotor and the compensating magnet (54) repel each other. In a center position, the rotor is bias-free by compensating the forces of attraction between the permanent magnet of the rotor and the yoke iron. As a result, the center position of the rotor can be adjusted with relatively small magnet coil flows. This results in small magnet coils, produces less heat and reduces the required power of the axial bearing.
摘要翻译：转子（12）以非接触方式安装在具有径向磁轴承（16,19）和轴向磁性轴承（40）的定子（14）中。轴向磁性轴承（40）产生具有安装在定子（14）上的磁体线圈（40）和轭铁（44）的轴向磁场。轴向磁化永磁体（50）设置在转子（12）上，位于与轭铁（44）大致轴向相对的位置。永久轴向磁化补偿磁体（54）设置在定子（14）上并且与转子（50）的永磁体轴向相对地布置并且沿相反方向极化，使得转子的永磁体（50）和补偿磁体（54）彼此排斥。在中心位置，通过补偿转子的永磁体和轭铁之间的吸引力，转子是无偏置的。结果，转子的中心位置可以用较小的磁体线圈流量来调节。这导致小的磁体线圈，产生较少的热量并减少轴向轴承的所需功率。

摘要： The invention relates to a friction vacuum pump (1) with a stator (3) and a rotor (4), which form at least two pump stages (12, 13, 14) with one gas inlet (23, 28) each, as well as with junction for the pump stages, which are equipped with junction openings (36,37) and serve for the connection of the gas inlets (23, 28) of the pump stages with devices to be evacuated; in order to avoid high conductance losses it is proposed that the junction openings (36, 37) are located in a plane which is disposed laterally adjacent to the pump stages (12, 13, 14) such that the distance between the junction openings (36, 37) and the rotor axis (15) is of minimum feasible size.

摘要： A multi-stage pump rotor (10) for a turbomolecular pump has at least two separate blade disk rings (17), each having a motor ring (12) and at least one blade disk (14). A cylindrical reinforcement pipe (18), which surrounds the rotor rings (12) of the blade disk rings (17) on the outside without clearance, is provided between the blade disks (14) of adjacent blade disk rings (17). The reinforcement pipe (18) absorbs a large part of the tangential forces occurring during operation such that the pump rotor (10) has improved stability at high rotor speeds.

摘要： A molecular vacuum pump (1) has a stator unit (9) and a rotor unit (8) disposed within a housing (2). A narrow gap is maintained during operation between the stator unit (9) and the rotor unit (8). The stator unit (9) and the rotor unit (8) are coupled together with respect to vibration to form a rotor/stator system (3). Elastic vibration elements (4, 5) mount the rotor/stator system in the housing such that the rotor/stator system rotates as a unit relative to the housing. Because the rotor and stator units vibrate together rather than relative to each other, very small, precise tolerances are maintained between them.

摘要： A friction vacuum pump (1) comprises a fixed element (7) bearing rows of stator blades (3) and a rotating element (6) bearing rows of rotor blades (2). The rows of stator blades and rotor blades are arranged concentrically with respect to an axis of rotation (4) of the rotating element (6) and mesh with each other. In order to create in the axial direct a short friction pump, the elements (6, 7) bearing the rows of rotor blades and stator blades extend in a substantially radial manner and the longitudinal axes of the blades (2, 3) extend in a substantially axial manner.

摘要： A mechanical kinetic vacuum pump with a stator (1), a rotor (6, 7) made from an aluminum or magnesium alloy and a rotor (6, 7) and a bearing shaft (3). The shaft (3) and the rotor (6, 7) are connected by a shrink- or screw-fit in a secure permanent connection. The rotor (6, 7) is made by spray forming. The main alloying component in the aluminum or magnesium alloy is silicon which is present in an amount such that the alloy has an expansion coefficient which essentially corresponds to the expansion coefficient of the shaft material.

摘要： A vacuum pump (1) includes a housing (2) in which a suction inlet opening (5) is defined. A vibration absorber (7) includes a suspension body (8) and an absorber jacket (9). The housing (2) of the vacuum pump (1) is connected directly to one end of the suspension body (8) in vacuum-tight connection and an opposite end of the suspension body carries a connecting port (14). By connecting the suspension body directly with the housing without mechanically releasable interconnection elements, the overall height of the pump and suspension body assembly is reduced.
