Abstract: A heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a compressor with a gas bearing supplied with compressed gas and a controller. The controller is configured to determine an inlet pressure and outlet pressure of the gas bearing, determine a maximum speed limit based on the inlet pressure and the outlet pressure, and prevent the compressor from operating at a speed that is greater than the maximum speed limit. A method of controlling a compressor includes calculating a maximum speed limit based on an inlet pressure and an outlet pressure of the gas bearing. The method also includes in response to determining that a speed setting is greater than the maximum speed limit, adjusting operation of the compressor such that a speed of the compressor is at or below the maximum speed limit.

Abstract: A heat transfer circuit includes a compressor, a condenser, an expander, and an evaporator that are fluidly connected together. The compressor includes a housing and a shaft rotatable relative to the housing to compress a working fluid received at a suction inlet, in which the shaft is supported by a gas bearing, and the gas bearing including a bearing housing having a fluid inlet and an outlet. A high pressure gas source is fluidly connected to the fluid inlet of the bearing housing for supplying high pressure fluid to the fluid inlet of the gas bearing such that the gas bearing supports the shaft when the shaft is rotating. A pressure reducer is connected to the outlet of the gas bearing is provided for reducing a vent pressure of the gas bearing.

Abstract: 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.

Abstract: 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.

Abstract: A hydrostatic bearing assembly for a shaft is disclosed, which consists of a base ring, two side rings enclosed up the base ring at both sides, and a plurality of hydrostatic blocks fixed respectively on surfaces of the base ring and of the side rings corresponded to the shaft, as result to hold the shaft to resist against loadings from the axial direction and/or the radial direction and provide lubrication through oil passages inside. These hydrostatic blocks are locked with screws or bolts on the base ring and on the side rings in order to be replaced individually on site.

Abstract: 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.

Abstract: 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.

Abstract: A method of fabricating a bearing surface for a gas or air bearing is described. 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.
