A tilt pad bearing may include a support structure having first and second support structure surfaces. A pivot may have first and second pivot surfaces, and the first pivot surface may be coupled to the second support structure surface. A pad may have first and second pad surfaces, and the first pad surface may be coupled to the second pivot surface. A path of fluid communication may extend from the first support structure surface, through the pivot, and to an opening in the second pad surface.

A turbocharger is provided including a housing with a turbine and a compressor disposed in the housing. A central shaft is connected between the turbine and the compressor and is rotatably supported by a first journal bearing disposed within the housing at a location adjacent to the turbine and a second journal bearing disposed within the housing at a location adjacent to the compressor. A spacer is disposed directly between and adjacent to the first journal bearing and the second journal bearing and is neither coupled to or integrally formed with the first journal bearing.

The present disclosure provides a bearing design that accommodates misalignment of a rotatable shaft in the bearing and is well suited to usage in a particulate-laden fluid. The bearing can be shaped with a curved surface along a longitudinal axis of the bearing, such as in a curved barrel shape or a ball shape, to provide a point contact instead of a line contact as is the case with conventional plain bearings. The point contact allows the bearing to adjust with a misalignment between ends of the shaft or between the external supports and facilitates the assembly and disassembly of the rotating shaft. Because the bearing compensates for misalignment, the bearing surfaces can have closer tolerances for a smaller gap between the bearing surfaces, which can result in improved performance.

A turbocharger assembly can include a housing with a through bore and an axial face disposed in the through bore; a locating plate with a keyed opening attached to the housing; and a journal bearing disposed in the through bore where the journal bearing includes a keyed compressor end and an enlarged outer portion defined between two axial faces by an outer diameter and an axial length where the axial face disposed in the through bore of the housing, the locating plate, and the two axial faces of the journal bearing axially locate the journal bearing in the through bore and where the keyed opening of the locating plate and the keyed compressor end of the journal bearing azimuthally locate the journal bearing in the through bore. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.

A bearing pad and bearing are provided which can inhibit the bearing pad from being deformed without increasing the costs. In a bearing pad (2), a conduit that extends from a first opening (3a) formed in a high temperature zone (2H) on a sliding surface (2a) opposing to a supported surface (1a) towards the direction apart from the supported surface (1a) and that finally reaches a second opening (3d) is formed.

A washer assembly and a hydrodynamic torque converter comprising the washer assembly is provided. The washer assembly comprises a washer and a plate; the washer is annular and comprises a washer body and two or more positioning clamps protruding radially inward from an inner periphery of the washer body, at least one side of the positioning clamp in a circumferential direction having a positioning protrusion protruding; the plate is annular, an inner periphery portion of the plate being provided with two or more positioning notches; an edge of at least one side of the positioning notch in the circumferential direction being provided with a positioning groove; and the washer is mounted to one end face of the plate. The washer assembly saves the internal space of the torque converter and saves the material cost of the washer.

A liquid guiding structure for a fluid dynamic pressure bearing, comprising: a fluid dynamic pressure bearing having an inner recess chamber and a liquid guiding trench which is formed between two sides of the inner recess chamber so as to form a circular close liquid guiding structure; wherein the liquid guiding trench includes at least two small V shape paths and at least one large V shape path; the large V shape path is larger than the small V shape paths and is located between the at least two small V shape paths. First angles at tip ends of the at least two small V shape paths are equal. A second angle between connections of the small V shape path and a respective large V shape path is larger than the first angle at tip ends of the at least two small V shape paths.

A nacelle for a wind turbine includes: a nacelle housing; a rotor hub; and a rotor bearing for bearing the rotor hub on the nacelle housing, wherein the rotor bearing has at least one inner ring element and at least one outer ring element, wherein at least one oil-lubricated sliding bearing element is formed between the inner ring element and the outer ring element. In the nacelle housing and/or in the rotor hub, a lubricating oil sump is formed in such a manner for receiving a lubricating oil for the sliding bearing element. The lubricating oil sump can be filled with lubricating oil up to a lubricating oil level, wherein at least a section of the rotor bearing is arranged in the lubricating oil sump vertically below the lubricating oil level.

A thrust bearing includes two physically separate one-piece segments. At least one segment has a wedge-shaped surface serving as a sliding surface. An alternative thrust bearing includes precisely one segment of a one-piece design. The segment is interrupted along its course around an axis of rotation of the thrust bearing. The segment has a wedge-shaped surface serving as a sliding surface.

A plain bearing includes: a bearing body; a radial bearing portion arranged on an inner peripheral surface of the bearing body; a thrust bearing portion arranged on an axial end surface of the bearing body; a damper portion arranged on an outer peripheral surface of the bearing body; a dam portion arranged on the outer peripheral surface of the bearing body; and an oil hole having an inlet that opens to at least one of the outer peripheral surface of the bearing body and the dam portion, and an outlet that opens to the inner peripheral surface of the bearing body. The inlet, at least a part of the dam portion, and the damper portion are arranged in this order from an axially inner side toward an axially outer side. An outlet of an upstream side oil passage is connected to the inlet on a radially outer side.
