Abstract: Rotor bearings for ESP motors can include anti-rotation tabs configured to engage with a stator during assembly of the ESP motor. Prior to insertion of the rotor bearing within the stator, the anti-rotation tabs may be held in place within axial slots in the outer surface of a bearing bushing of the rotor bearing using retention rings. The retention rings and the bearing bushing may be configured to allow for interference fit.

Abstract: A clearance is created between an inner circumference of a bushing main body (2) which surrounds a rack (5) across a row of rack gear teeth (50) and an outer circumference of the rack (5), and two supporting surfaces (21A, 21B) which face each other with a bushing main body axis O therebetween and a supporting surface (21C) which faces a back surface of the rack (5), each extending along an x-axis direction, are formed on the inner circumference of the bushing main body (2). The rack (5) in a neutral state is supported by the two supporting surfaces (21A, 21B) so as to be displaceable along a z-axis direction, and the rack (5) in operation is stably supported by the three supporting surfaces (21A-21C) at three places. A groove bottom position of an annular elastic member attachment groove (24), which is formed on an outer circumference of the bushing main body (2), is offset toward the support surface (21B) only in an area on a support surface (21B) side from the bushing main body axis O, and therefore an elastic ring (3) attached to the elastic member attachment groove (24), protrudes above an outer circumferential surface of the bushing main body (2), but only in the area on the support surface (21B) side from the bushing main body axis O.

Abstract: A rotor bearing for bearing a rotor hub on a nacelle housing of a nacelle for a wind turbine has at least one inner ring element and at least one outer ring element, wherein at least one sliding bearing element is arranged between the inner ring element and the outer ring element, which sliding bearing element is fastened to the inner ring element or to the outer ring element. On the sliding bearing element, a sliding surface is formed, which cooperates with a counterface, which is coupled with that ring element, to which the sliding bearing element is not fastened. The counterface is designed to be resilient.

Abstract: A turbo fluid machine includes a partition wall separating an inside of a housing into a compression space and a bearing space; and a foil bearing. The partition wall includes a support part having an end face raised toward a thrust collar in an axial direction. The support part has a groove formed in the end face and radially extending to an outer peripheral surface of the support part. Top foils of the foil bearing each have one surface facing the thrust collar and the other surface elastically supported by corresponding one of bump foils of the foil bearing. The foil bearing is mounted on the end face such that a position of the groove corresponds to a position of a gap between the bump foils and a position of a gap between the top foils and such that the groove faces the thrust collar in the axial direction.

Abstract: A journal foil bearing system includes a journal member with a bore and an internal groove. The system includes a shaft received within the bore and supported for rotation relative to the journal member about an axis. The groove extends substantially along the axis. The system also includes at least one biasing foil and a top foil member with at least one arch-bound top foil. The top foil member has a top foil first end and a top foil second end. Additionally, the system includes a foil support insert member that is received within the groove. The foil support insert member includes a spacer member that is disposed between the top foil first and second ends. The spacer member maintains the top foil first and second ends separated, at least, at a distance.

Abstract: A system includes a first structure having an upper surface coupled to a second structure by a fastener assembly including a bushing positioned within an opening in the upper surface of the first structure. An inner opening of the bushing defines an inner diameter, and a fastener is at least partially positioned within the bushing. An outer surface of the fastener defines an outer diameter of the fastener. The bushing and the fastener are configured such that a space between the outer surface of the fastener and the inner opening of the bushing defines a gap which increases in size in a direction extending from the upper surface to the lower surface of the first structure.

Abstract: A pillow block bearing seal for sealing the shaft opening around the shaft of a pillow block, having a stator assembly, a rotor, and a resilient cylinder sleeve. The stator assembly has a cylindrical base having an axial length that is configured to accept the shaft passing there through, and a stator extending annularly from an axial end of the cylindrical base. The rotor is configured to attach to and rotate with a rotatable shaft, and has an axially inward-facing surface that confronts the axially outward-facing surface of the stator to define labyrinth interface passage. The resilient cylindrical sleeve is fixed to an outer surface of the cylindrical base for contact with a pair of annular ribs of the bearing housing, for stabilizing the alignment of the center line of the shaft with the bearing housing.

Abstract: A turbocharger includes a shaft extending between a first shaft end coupled to a turbine wheel, and a second shaft end coupled to a compressor wheel. The turbocharger also includes a bearing housing assembly including a bearing housing presenting an interior surface having a first diameter. The interior surface defines a bearing housing interior. A bushing is disposed in the bearing housing interior, extends between first and second bushing ends, is coupled to the shaft, and includes a first anti-rotation component. A retention shoulder extends away from the interior surface and radially inward proximate to one of the first and second bushing ends, and presents an inner surface having a second diameter less than the first diameter to limit axial movement of the bushing. The retention shoulder includes a second anti-rotation component engagable with the first anti-rotation component to limit rotational movement between the bushing and the bearing housing.
