An interconnected bearing linkage system having two or more horizontal two-axis combined journal and thrust bearings with self-lubricating liners therein, two or more vertical single-axis sleeve bearings with self-lubricating liners therein and one or more vertical thrust bearing with self-lubricating liners therein, that cooperate with one another to accommodate vertical and horizontal angular movement relative to one another.

A tilting pad bearing including pads disposed around a rotating shaft so as to face an outer peripheral surface of the rotating shaft, liners each supporting an outside of the pad in a radial direction with an axis of the rotating shaft as a center, and pivots each supporting an outside of the liner in the radial direction with the axis as a center at a central position of the liner in an axial direction of the rotating shaft so as to allow the pad to be swingable, wherein a recessed portion recessed in a direction away from the pad is formed on a surface of the liner facing the pad or a surface of the pad facing the liner at least at the central position thereof in the axial direction of the rotating shaft.

A bearing element for a bearing assembly has a body of polycrystalline diamond (PCD) material having a bearing contact surface, and a substrate bonded to the body of PCD material along an interface and having a free end surface. The substrate has a through-bore extending longitudinally therethrough, the body of PCD material having a portion extending through the through-bore in the substrate to at least the free end surface thereof, the substrate extending around the peripheral side edge of the portion of PCD material extending therethrough.

The present disclosure relates to a thrust bearing which is disposed to face a thrust collar provided in a rotation shaft. The thrust bearing includes a top foil, a back foil, and a base plate. The back foil includes a plurality of back foil pieces which are arranged in a circumferential direction of the base plate, and the top foil includes a plurality of top foil pieces which are respectively disposed on the back foil pieces. An inner peripheral recessed portion is formed at a portion which supports an inner peripheral side end of the back foil piece in a surface supporting the back foil in the base plate.

The present disclosure is directed to a bearing assembly for a gas turbine engine. The bearing assembly includes a bearing housing and a bearing pad for supporting a rotary component of the gas turbine engine. The bearing pad includes at least one gas inlet and a plurality of gas outlets configured on an inner surface thereof. The gas inlet is in fluid communication with the plurality of gas outlets via a gas distribution labyrinth. Further, the gas distribution labyrinth includes a plurality of passageways configured to evenly distribute pressurized gas entering the gas inlet to an interface between the inner surface of the bearing pad and an outer diameter of the rotary component.

A journal bearing, in which a lower half carrier ring is disposed on the outer peripheral side of a horizontally installed rotating shaft, and an upstream side pad and a downstream side pad are disposed on the inner side of the lower half carrier ring, includes an upstream side oil supply portion and downstream side oil supply portion which supply lubricant oil to the upstream side pad and downstream side pad, the bearing being characterized in that the supply quantity of lubricant oil supplied from downstream side oil supply nozzles of the downstream side oil supply portion is adjusted so as to be less than the supply quantity of lubricant oil supplied from upstream side oil supply nozzles of the upstream side oil supply portion.

Provided is a tilting pad type journal bearing capable of reducing the amount of oil that has to be supplied to the bearing. A bearing comprises nozzles 5 which are each arranged between pads 2 to supply lubricating oil to sliding surfaces 14 of the pads 2. The sliding surface 14 of each of the pad 2 is formed so that the width of the sliding surface 14 increases as it goes from a front edge part towards a rear edge part thereof. A tip end part of each of the nozzles 5 has a groove part 18 which induces a flow heading from lateral parts towards the center in the width direction, in an oil flow from the rear edge part of the sliding surface 14 of an upstream pad 2 to the front edge part of the sliding surface 14 of a downstream pad 2.

A bearing arrangement for a wind turbine including a bearing housing and a drive shaft, whereby the drive shaft is arranged within the bearing housing in an axial direction along a longitudinal axis of the bearing housing, the bearing arrangement further comprising a downwind bearing and an upwind bearing as radial fluid bearings, whereby the downwind bearing and the upwind bearing are arranged between the bearing housing and the drive shaft is provided. The downwind bearing and/or the upwind bearing includes a lubricant flooded chamber, in which multiple radial bearing pads are arranged about the drive shaft, whereby the lubricant flooded chamber is sealed against the drive shaft, an internal space of the bearing housing and an outside of the bearing housing is also provided.
