摘要： A spindle unit for a machine tool for fine-machining workpieces having groove-shaped profiles, has a rotatably mounted spindle shaft (2). The spindle shaft is subdivided in the axial direction (AR), one behind the other, into a fastening portion (A) for fastening a tool (4) or a workpiece to be machined, a first bearing portion (B), a force transmission portion (C), and a second bearing portion (D). A drive unit (5) serves to drive the spindle shaft by way of force transmission onto the force transmission portion. A first and a second bearing point (13, 14) are designed to bear the spindle shaft in the first bearing portion, and a third bearing point (15) serves to mount the spindle shaft on the second bearing portion. The first and the second bearing points each have one or more hydrostatic bearings. The third bearing point has one or more hydrostatic and/or hydrodynamic bearings.

摘要： A high-speed permanent magnetic motor assembly generates a magnetic field to produce mechanical output power. The assembly comprises a motor, a motor housing, and a radial bearing block. A motor housing supports a rotor and the radial bearing block with a left radial aerostatic bearing, a right aerostatic bearing, and an axial thrust aerostatic bearing. The bearings are porous aerostatic bearings that use a low-viscous vapor-liquid two-phase fluid as a lubricant, which penetrates through a porous bushing. The liquid vaporizes from pressure reduction, and part of the liquid arrives at a clearance between each of the bearings and the rotor. The liquid of the two-phase fluid is vaporized during discharge along an axial direction from the bearing. This increases the vapor in the clearance, improve a bearing capacity, retain position accuracy of an aerostatic bearing, and cool the aerostatic bearings and the rotor.

摘要： The present invention is directed to a shaft bearing support assembly for waterborne equipment, including: at least one bearing; at least one tapered forcing ring; a housing; and at least one adjusting device. The outer circumference of each of the at least one bearing is surrounded by one tapered forcing ring which is arranged inside the housing. The at least one adjusting device communicates with each of the at least one tapered forcing ring. A force generated by the at least one adjusting device is transmitted to the at least one tapered forcing ring to longitudinally move the at least one tapered forcing ring, causing the at least one bearing to constrict radially and to adapt to a desired clearance over a diameter of a shaft.

摘要： A hydrostatic bearing adapted to be mated with a base includes a floating seat and a holder. The floating seat is made from a porous material and formed with a bearing surface that has a contour conforming to that of the base. The holder is coupled to the floating seat and cooperates with the floating seat to define an accommodating space for accommodating pressurized air. A pressurized air film is formed between the base and the bearing surface of the floating seat when the pressurized air discharges from the accommodating space through the floating seat so as to separate the floating seat from the base and so as to support the base.

The method comprises taking a bulk bearing portion having at least one bearing surface region and providing a coating on the bearing surface region to define at least one gas pocket). The at least one gas pocket has a depth substantially equal to the thickness of the coating. In one example, laser ablation is used to remove part of the coating to form the gas pockets. The coating may be an anodized coating and the bulk bearing portion may be formed from aluminium. An air bearing component formed using the method is also described.
