摘要： A cutting apparatus such as a metal-cutting circular saw apparatus has an axially displaceable shaft for mounting a saw blade. The shaft is hydrostatically supported both in the radial and in the axial direction. To provide for the axial displaceability of the shaft, the shaft is axially hydrostatically supported at one end by means of an annular piston. The piston bears with a radial end portion thereof against a shoulder in the bearing housing, the shoulder projecting into the cylinder in which the piston is displaceable. The piston is of such a cross-sectional shape and elasticity that in an operative position it is elastically pivoted or tilted, thereby reducing the clearance between the piston and the cylinder, so the piston can carry bearing forces in a radial direction, and also eliminating the need for piston sealing means.
摘要翻译：切割装置如金属切割圆锯装置具有用于安装锯片的可轴向移动的轴。轴在径向和轴向都是静压支撑的。为了提供轴的轴向位移性，轴通过环形活塞在一端轴向地被静态地支撑。活塞的径向端部抵靠轴承壳体中的肩部，凸肩突出到活塞可移位的气缸中。活塞具有这样的横截面形状和弹性，即在工作位置上，活塞枢转或倾斜，从而减小了活塞与气缸之间的间隙，因此活塞可沿径向方向承载轴承力，同时消除需要活塞密封装置。

摘要： A pneumatic bearing arrangement comprising an outer element and an inner element which both have generally conical configurations. The elements also have concave and convex bearing surfaces, respectively. The elements are disposed in generally concentric relation and define a generally conical bearing space therebetween. A plurality of nozzles are provided on the elements and open adjacent to the bearing surfaces of the elements. A shaft having a generally conical journal member with an inner and outer face is rotatably supported by the bearing space such that a gap exists between the journal and the inner and outer bearing surfaces. When air is jetted into the bearing space through the nozzle air films are created for maintaining the journal floating between the bearing surfaces without contacting either of the surfaces. The outer element, inner element and journal member can be formed with a substantially bell-shaped configuration to increase the bearing surface for both thrust and radial loads. A plurality of journal members can be provided at spaced locations along a shaft which are accommodated by respective pairs of outer and inner elements spaced along the arrangement. The journal members are maintained in a balanced position within the bearing spaces.

摘要： An aerodynamically supported roller bearing is disclosed, having means for connecting a compressed gas supply and using the compressed gas to bring the roller up to a desired speed. The design of the roller then permits the compressed gas supply to be reduced or turned off while the roller continues to be aerodynamically supported. Advantageously, some minimal compressed gas is continued through the roller to purge the roller of potential dust particles interfering with the operation of the roller.

摘要： An aerostatic bearing for the shaft of a spinning turbine of an open end spinning unit. The shaft is located in a cylindrically hollow housing to which gas under pressure is supplied to form a radial aerostatic bearing about the shaft. A permeable supporting sleeve is preferably interposed between the housing and the shaft. The shaft is provided with a radial duct and an axial bore opening only toward the rear end of the shaft. A supporting surface is fixed opposite the rear end of the shaft and is spaced therefrom so that the exhausting gaseous media impinges thereon and forms an axial bearing. Preferably, means are provided for resiliently biasing the shaft toward the supporting surface against the action of the axial aerostatic bearing. Such means are preferably magnetic.

摘要： A friction welding apparatus is particularly adapted for the friction welding of relatively heavy workpieces, as for example the center section and wheel bearing end spindles of a drive axle housing, and comprises special hydrostatic bearing equipped devices for mounting the rotating workpieces. Each such device is mounted for axial displacement and comprises a rotatable arbor assembly to which the rotatable workpiece, such as a wheel bearing end spindle, is clutched and the arbor assembly is rotatably supported in a housing by two axially spaced hydrostatic journal bearings. Front and rear hydrostatic thrust bearings are provided between the arbor assembly and the housing. Oil under suitable pressure is supplied to both the journal and thrust hydrostatic bearings, and controls are provided for attaining and maintaining suitable fluid pressure levels at these bearings. One aspect of control insures that the workpiece is not secured to the arbor assembly until journal bearing oil pressure reaches a certain level. Oil is forced under high pressure into the bearings through specially arranged passages and after being discharged from the hydrostatic bearings returns to a sump at lowered pressure.

摘要： A ROTARY SHAFT PASSING THROUGH THE WALL OF AN ATOMIC REACTOR IS SEALED AGAINST LEAKS AROUND THE SHAFT BY TWO SETS OF BAFFLES ON THE SHAFT SPACED FROM EACH OTHER AND COOPERATING WITH A SUPPORT MOUNTED IN THE WALL OF THE REACTOR RECEIVING THE SHAFT. A FLUID FILM THRUST BEARING FOR THE SHAFT IS MOUNTED IN THE SUPPORT BETWEEN THE SETS OF BAFFLES AND A CENTERING FLUID BEARING FOR THE SHAFT IS MOUNTED WITHIN THE SUPPORT. A NEUTRAL GAS UNDER PRESSURE IS ADMITTED TO THE SHAFT ADJACENT TO THE FIRST SET OF BAFFLES AND BETWEEN IT AND THE EXTERIOR OF THE REACTOR WITH SEALING MEANS ENGAGING THE SHAFT AND MOUNTED IN THE SUPPORT EXTERIOR THEREOF. PUMPING MEANS ARE PROVIDED AROUND THE SHAFT BETWEEN THE FIRST SET OF BAFFLES AND THE POINT OF ADMISSION OF THE NEUTRAL GAS. SECOND PUMPING MEANS ARE PROVIDED OPENING AROUND THE SHAFT BETWEEN THE THRUST BEARING AND THE SECOND SET OF BAFFLES. A METALLIC SEAL IS PROVIDED AROUND THE SHAFT ENGAGING THE SUPPORT WHEN THE SHAFT IS AT REST.
