摘要： A bearing assembly for a rotating shaft, with brush rings on both sides of the bearing mechanism for damping bearing motion. In a foil gas bearing embodiment, the bearing itself comprises a hollow sleeve, a compliant layer, and a top foil layer. These bearing elements are arranged in a conventional manner except that the top foil layer extends beyond the sleeve. A sleeve extension extends over the extended portion of the top foil layer. Two opposing brush rings, an inner brush ring and an outer brush ring, are attached to the top foil layer extension and the sleeve extension, respectively. The bristles of an inner brush ring and the bristles of an outer brush ring are interposed and provide damping during operation of the bearing.

摘要： A gas bearing (100) having pressurised axially extending chambers (110) in a housing (102) having a shaft bore (104) therein, the axially chambers (110) being in fluid communication with a bearing surface (108) that defines the bore via laser-drilled capillaries (118). The end (122) of each laser-drilled capillary at the bearing surface (108) is flared such that the narrowest portion of the capillary is set back from the bearing surface (108). This shape can ensure that the load carrying function of the bearing (100) does not fail during shaft eccentricity by ensuring that pressure restriction must happen within the capillary and not the gap being shaft and bearing surface. The bearing surface may face in an axial and/or radial direction with respect to the shaft. The axial chambers may be pressurised axially such that the outer circumference of the housing is unbroken and hence usable for other purposes.
摘要翻译：一种在其中具有轴孔（104）的壳体（102）中具有加压的轴向延伸的腔室（110）的气体轴承（100），所述轴向腔室（110）与限定所述孔的轴承表面（108）流体连通通过激光钻孔毛细管（118）。在轴承表面（108）处的每个激光钻孔的毛细管的端部（122）被扩张，使得毛细管的最窄部分从支承表面（108）回退。这种形状可以通过确保在毛细管内发生压力限制，而不是轴和轴承表面的间隙，确保轴偏心时承载功能不会失效。轴承表面可以面向相对于轴的轴向和/或径向方向。轴向室可以轴向加压，使得外壳的外圆周不间断，因此可用于其它目的。

摘要： A bearing system in which an axially stiff narrow gap fluid dynamic gas bearing is preloaded by an axially less stiff larger gap fluid dynamic bearing. As an example two fluid dynamic bearings are provided spaced apart along a shaft, one of the bearings comprising a fluid dynamic bearing, the other comprising an air bearing. The fluid dynamic bearing has a larger gap, while the air bearing has a relatively small gap. The overall working surface area of the air bearing may be twice as much or more than the working surface area of the fluid bearing.

摘要： The invention relates to a gas bearing of a rapidly rotating shaft, whose end supports a tool, in particular to a gas bearing of a rapidly rotating shaft, whose end supports a polygon mirror (27) for a spindle of an optical application. To provide radial support along the shaft (3), gas bearings are arranged in a housing (5), whereby a first gas bearing (9) and a third gas bearing (8) are positioned concentrically in relation to one another and a second gas bearing (2), which is located midway between the first gas bearing (9) and the third gas bearing (8), is mounted in an eccentrically offset manner to the first gas bearing (9) and the third gas bearing (8). The invention is also provided with an adjusting device (1) for increasing the eccentric offset of the second gas bearing (2) as the rotational speed of the shaft (3) increases.
