SLIDING BEARING PAD SUPPORT
The invention relates to a support of a bearing pad of a sliding bearing.
Provided is a bearing pad support connection including a bearing pad and a bearing pad support, whereby the bearing pad is connected to the bearing pad support by a pivot joint. The pivot joint includes a pivot pocket, and a pivot.
The pivot pocket includes a sealing that abuts on the pivot of the pivot joint.
CORROSION RESISTANT BEARING ELEMENTS, BEARING ASSEMBLIES, BEARING APPARATUSES, AND MOTOR ASSEMBLIES USING THE SAME
Embodiments disclosed herein relate to bearing assemblies and methods of manufacturing. In an embodiment, a bearing assembly includes a support ring and bearing elements. The bearing elements are mounted to and distributed circumferentially about an axis of the support ring. At least one of the bearing elements includes a polycrystalline diamond table, a substrate bonded to the polycrystalline diamond table, bonding region defined by the substrate and the polycrystalline diamond table, and a corrosion resistant region. The corrosion resistant region includes a corrosion resistant material that covers at least a portion of at least one lateral surface of the bonding region. The corrosion resistant region prevents corrosion of at least some material in the bonding region covered by the corrosion resistant region (e.g., during use). Other embodiments employ one or more sacrificial anodes as an alternative to or in combination with the corrosion resistant region.
HYDRODYNAMIC SIDE PLATE FOR TORQUE CONVERTER STATOR
A hydrodynamic side plate for a stator in a torque converter includes a first radial surface, a second radial surface opposite the first radial surface, a first axial restriction surface on the first radial surface opposite an inner race of a stator assembly, a second axial restriction surface on the first radial surface opposite locking components of the stator assembly, and a plurality of hydrodynamic pads in the second radial surface separated by a plurality of corresponding radial grooves. The first axial restriction surface is configured to restrict axial movement of the inner race of the stator assembly. The second axial restriction surface is configured to restrict axial movement of the locking components of the stator assembly. The second radial surface comprises at least two anti-rotation tabs configured to prevent relative motion with the stator assembly.
STATIONARY THRUST BEARING OF A STATIONARY AND ROTATING THRUST BEARING SYSTEM INTENDED FOR WITHSTANDING AN AXIAL LOAD
A stationary thrust bearing is for a stationary and rotating thrust bearing system designed to withstand an axial load along an axis of a rotation shaft mounted in a guide bearing, in particular of a turbocharger. The stationary thrust bearing includes a flange in which is created a through-opening that allows the rotation shaft to pass through and has, on a face, pads with structured regions. Specifically, at least two sets of the pads, which include a first set of pads with structured regions present in a first ring on the face of the flange, and a second set of pads with structured regions present in a second ring, coaxial with the first ring, on the face of the flange, set back relative to the first set of pads in the longitudinal direction of the axis of the opening.
Hydrodynamic bearing features
A system includes a hydraulic transfer system configured to exchange pressures between a first fluid and a second fluid, where the first fluid has a pressure higher than the second fluid, includes a sleeve comprising an elliptical shape, a cylindrical rotor disposed within the sleeve in a concentric arrangement, where the cylindrical rotor is configured to rotate circumferentially about a rotational axis and has a first end face and a second end face disposed opposite each other. The system includes a first and second end cover having a first and second surface which interface with a first and second end face of the rotor. The system includes a first and a second radial clearance disposed between the sleeve and the cylindrical rotor, where the radial clearances are configured to increase or decrease based at least in part on a pressure differential.
Tilting pad bearing assemblies, and bearing apparatuses and methods of using the same
Embodiments disclosed herein are directed to tilting pad bearing assemblies, bearing apparatuses including the tilting pad bearing assemblies, and methods of using the bearing apparatuses. The tilting pad bearing assemblies disclosed herein include a plurality of tilting pads. At least some of the superhard tables exhibit a thickness that is at least about 0.120 inch and/or at least two layers having different wear and/or thermal characteristics.
Gas bearings
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 pressurized gas fluidly connected with the bearing and a control system (134) for regulating the supply of pressurized 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 pressurized 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.
MACHINE THRUST BEARING ASSEMBLY
A thrust bearing assembly for a machine includes a stator housing, a fluid film thrust bearing, and a ring bearing. The stator housing surrounds at least a segment of a rotor shaft and one or more runners on the rotor shaft that include a first runner surface and a second runner surface facing in opposite axial directions along the rotor shaft. The fluid film thrust bearing is axially held between a first stator surface of the stator housing and the first runner surface. The fluid film thrust bearing is configured to generate a fluid cushion that blocks the first runner surface from engaging the fluid film thrust bearing. The ring bearing is axially held between a second stator surface of the stator housing and the second runner surface. The ring bearing has an annular contact surface that engages the second runner surface to axially support the rotor shaft.
