A bearing assembly includes a housing, a spherical bearing located within the housing, and two outer races positioned between the spherical bearing and the housing. The outer races are configured in sliding engagement with the spherical bearing to allow the spherical bearing to rotate relative to the housing. The assembly also includes a tightening element configured to engage a first of the two outer races and tighten the outer races against the spherical bearing. The assembly is configured to provide a primary load path from the tightening element to the housing, wherein the primary load path leads from the tightening element to the housing via the outer races whilst bypassing the spherical bearing.

Provided is a fluid film bearing, especially for a rotor hub in a wind turbine, including an inner part that supports a rotating outer part, wherein the inner part includes multiple radial pads distributed along the outer circumference of the inner part, each of the radial pads having at least one radial pad sliding surface, wherein the radial pad sliding surfaces support at least one outer part sliding surface of the outer part in the radial direction.

A transport system for delivery or retrieval of a biostimulator, such as a leadless cardiac pacemaker, is described. The biostimulator transport system includes a docking cap supported by a bearing within a bearing housing. The bearing allows relative rotation between a torque shaft connected to the docking cap and an outer catheter connected to the bearing housing. The bearing housing and the docking cap include respective bearing retainers that constrain the bearing within the bearing housing without a weld attachment. The weldless retainers of the biostimulator transport system provide a robust mechanical securement of the bearing that is not vulnerable to corrosion. Other embodiments are also described and claimed.

A method for modifying an existing single shaft combined cycle power plant having a steam turbine part and a gas turbine part which are connected to each other rigidly by an intermediate shaft. The gas turbine part is supported by two pin-ended supports allowing a certain axial displacement of the casing by rotating about corresponding axes. The old gas turbine part is replaced by a new gas turbine part having a different structure, namely a rigid support and a flexible support. Relative thermal expansion or displacement of the intermediate shaft is compensated by a hydraulic unit comprising a double-acting piston for displacing the gas turbine rotor with respect to the gas turbine stator. The hydraulic unit is controlled based on a displacement measurement in the steam turbine.

A system for the axial retention of a holding ring for a bearing for guiding in rotation a rotary shaft of a turbomachine is disclosed. The system includes an annular bearing support and a bearing holding ring that is borne by the annular bearing support. The bearing holder ring includes an upstream ring configured to be brought into contact with the bearing support and a downstream ring that is elastically deformable. The bearing support has a first axial retention element, and the bearing holding ring has a second axial retention element. The first and second axial retention elements are configured to cooperate with one another to axially retain the bearing holding ring in the event of damage to the downstream ring.

A gas bearing for a compressor includes a bearing portion and a sealing portion mounted to a bearing housing of the compressor via one or more dampers, and the sealing portion being fixedly connected to the bearing portion, and a vent with an inlet in the bearing. The bearing portion has an inner radial surface for radially supporting a shaft of the compressor. The sealing portion has a sealing surface. The inlet of the vent disposed between the inner radial surface and the sealing surface. The sealing surface and a rotating surface form a path that extends along the sealing surface. The path extending from a pressurized volume of the compressor to the vent, and the pressurized volume containing a fluid.

There are disclosed apparatuses and methods for withdrawal of a bearing from a gate mechanism including a mechanism housing, a carrier assembly, and discrete fasteners. The mechanism housing includes a receiving bore as well as housing fasteners and housing surfaces located about a periphery of the receiving bore and offset from one another. The carrier assembly includes a carrier housing having a carrier support mating with the receiving bore and a carrier bearing supported for rotation within the carrier housing. The carrier housing has flange fasteners aligning with the housing fasteners and the housing surfaces when the carrier housing mates with the receiving bore. The carrier assembly withdraws from the mechanism housing in response to removing the discrete fasteners from a first group of the flange fasteners aligned with the housing fasteners and inserting the discrete fasteners to a second group of the flange fasteners aligned with the housing surfaces.
