摘要： A pair of sliding members sliding relative to each other at sliding faces is configured such that at least one of the sliding faces includes a negative pressure generation mechanism separated from a leakage side by a leakage-side land portion and a land portion arranged in the negative pressure generation mechanism. In the compact sliding members, sliding torque can be reduced and a sealing function can be maintained.

摘要： An annular sliding component has a sliding surface relatively sliding with eccentric rotation. The sliding surface is provided with a plurality of grooves each of which is open to a fluid space on at least one of an inner diameter side and an outer diameter side of the sliding surface and arranged in a circumferential direction. The groove is partially defined by a first side wall surface formed along the circumferential direction of the sliding surface and a second side wall surface connected to the first side wall surface and formed along a radial direction of the sliding surface.

摘要： A gas bearing system has at least one gas bearing (30, 32, 34) with a moving part and a static part and which can be operated in both aero-dynamic and aero-static modes. The system has a source (36) of pressurised gas fluidly connected with the bearing and a control system (134) for regulating the supply of pressurised gas to the bearing in dependence on the rotational speed of the moving part. The system has particular application in a turbocharger (1) where a flow of pressurised gas from the source is introduced into the bearing at the start-up and slow down phases of operation of the turbocharger, the flow being stopped, or reduced, when the turbocharger has reached normal operating speeds.

摘要： A synthetic resin-made sliding bearing 1 includes a synthetic resin-made upper casing 3 having a cylindrical outer peripheral side surface 2; a synthetic resin-made lower casing 6 which has a cylindrical inner peripheral side surface 5 opposed to the outer peripheral side surface 2 on an outer side in a radial direction A so as to surround the outer peripheral side surface 2 with a cylindrical fitting clearance 4 extending in a vertical direction B intersecting the radial direction A, and on which the upper casing 3 is mounted as the upper casing 3 is fitted thereto such that the displacement of the lower casing 6 with respect to the upper casing 3 in the radial direction A is made possible with a width a as a minimum width of the fitting clearance 4 in the radial direction A by being restricted by the contact of the inner peripheral side surface 5 with the outer peripheral side surface 2; and a synthetic resin-made thrust sliding bearing 9 disposed in an annular space 7 between the upper casing 3 and the lower casing 6 in the vertical direction B.

摘要： A centrifugal compressor includes a rotation shaft, an impeller, a housing including a first chamber, a second chamber of which pressure is lower than the first chamber, and a partition wall that partitions the first chamber and the second chamber and includes a through hole through which the rotation shaft is inserted, and a seal member arranged in the housing. The seal member includes a gas seal and a support. When the rotation shaft is rotating, the gas seal surrounds an outer circumferential surface of the rotation shaft in a non-contact state in which dynamic pressure forms a gap between the gas seal and the outer circumferential surface of the rotation shaft. The support supports the gas seal in a state in which the gas seal is movable in a direction intersecting an axial direction of the rotation shaft.

摘要： A hybrid dynamic pressure gas thrust bearing, comprises two outer discs, an inner disc clamped between the two outer discs, and foil type elastic parts arranged between each outer disc and the inner disc; and the two end faces of the inner disc are respectively provided with regular groove-type patterns, and the groove-type pattern in one end face is in mirror symmetry with the groove-type pattern in the other end face. The hybrid dynamic pressure gas thrust provided by the invention has the rigidity characteristic of the high-limit rotating speed of the groove-type dynamic pressure gas thrust bearing, and has the flexible characteristic of the high impact resistance and the load capacity of the foil type dynamic pressure gas thrust bearing, it can meet the application of dynamic pressure gas thrust bearings in ultra high-speed areas under larger loads.

摘要： A thrust bearing pad includes a relatively low wear and low friction contact layer disposed on a metallic substrate. The metallic substrate allows a manufacturer to couple the thrust bearing pad to a corresponding metallic thrust bearing in a relatively secure manner while the contact layer extends the operating life of the thrust bearing and minimizes maintenance.
