Self-adjusting bushing bearing having a springy element
Self-adjusting bushing bearings having a springy element. The self-adjusting bushing bearing has a bearing subassembly that is configured to be received in a housing and also has a plurality of bearing segments that together are configured to receive a shaft therein. A springy element biases the plurality of bearing segments radially inwardly towards the shaft. The springy element is mated with at least one bearing segment in the plurality of bearing segments.
ENHANCED DURABILITY DRIVE LINK FOR HIGH LOAD MISALIGNMENT
The present disclosure provides a drive link assembly that includes a case having a spherically formed inner ring. A clevis is affixed to a surface of the case such that is disposed horizontally between a first end and a second end of the clevis. A spacer having a spherical inset portion is positioned on the surface horizontally between the clevis and the spherically formed inner ring, such that the spherical inset portion is aligned with the spherically formed inner ring. A spherical bearing is seated within the spherically formed inner ring. A rod is affixed to an outer surface of the spherical bearing.
Angular contact self-aligning toroidal rolling element bearing
An angular contact self-aligning toroidal roller bearing comprising an inner ring, an outer ring, and a set of rolling elements formed of rollers arranged in an intermediate configuration between the inner and outer rings. Each roller is arranged to self orient in its axial direction in relation to the inner and outer rings in a loaded zone during operation. Furthermore, a method for determining dimensional parameters of structural members of an angular contact self-aligning toroidal rolling element bearing and a method for manufacturing an angular contact self-aligning toroidal rolling element bearing are described herein.
Device for the rotation of objects (embodiments) set for the rotation of ojbects
A device for rotation of an object disposed on a horizontal surface, about a vertical axis, includes a base for an object, for rotation about a vertical central axis of the base, at low rotational speeds without achieving the gyroscope principle. The base has a lower surface, at least one downwardly projecting, central pivot lug for rotation of the base thereupon and at least one lateral lug spaced radially from the central lug and having a height less than the central pivot lug. The base is configured and dimensioned to rotate when caused to spin while being continuously supported both by the central pivot lug and at least a portion of the lateral lug as it spins. The base is tilted from the vertical axis at a minor angle, with the difference in heights of the central lug and lateral bearing lugs ranging from 0.025 to 1.25 mm.
AXIAL SLIDING BEARING ARRANGEMENT FOR A PUMP IMPELLER OF A RADIAL PUMP AND A RADIAL PUMP COMPRISING THE AXIAL SLIDING BEARING ARRANGEMENT
Axial sliding bearing arrangement for a pump impeller of a radial pump and a radial pump comprising the axial sliding bearing arrangement
Axial sliding bearing arrangement for a pump impeller (8) of a radial pump (1) with a first, rotating friction surface (22) pointing in an axial direction (A), a second, non-rotating friction surface (23) facing the first, rotating friction surface (22), wherein the second, non-rotating friction surface (23) is allocated to a swivel head body (20), wherein the swivel head body (20) is axially supported via an axial support surface (24), and the swivel head body (20) is radially supported in a resiliently yielding manner at radial support surfaces (25) by means of first spring means (31).
Tilt pad bearing with through-pivot lubrication
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.
Plain bearing and method for its manufacture
A newly built plain bearing has an inner ring and an outer ring each having a sliding surface along which the rings are movable relative to each other. The sliding surfaces are spaced from each other by an intermediate space that holds an initial greasing, and at least one of the sliding surfaces includes an anti-corrosion coating.
Compliant bearing for oilfield applications
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.

Greased bearing track
A bearing assembly includes a cylindrical configuration with a radial direction, a circumferential direction and defining a bearing assembly longitudinal axis, a first axial end, and a second axial end, an inner radial race, an outer radial race, a bearing member configured to be disposed radially between the inner radial race and the outer radial race, and a retaining ring configured to engage the inner radial race and the outer radial race, the retaining ring being configured to limit longitudinal movement of the inner radial race relative to the outer radial race once assembled.
