A removable spindle assembly improvement comprised of a spindle housing end unit having a threaded cavity. A corresponding threaded removable spindle is torqued into the threaded cavity. The spindle has a tapered section that includes O-rings for creating a seal along the corresponding section of the cavity to prevent corrosion which assists in the elimination of spindle seizure within the spindle housing end unit's cavity. The spindle housing end unit's housing includes at least two threaded apertures that cooperate with sealed set screws for securing the spindle in place during operation. The set screws are placed apart at an odd number of 15 degree increments. This assembly facilitates easy removal and replacement of a spindle on a spring axle.

A wheel hub assembly for tension spoke wheels is provided. The wheel hub assembly has a construction that automatically adjusts the position of the axle bearings along the rotational axis of the hub assembly to take-up slack between the axle bearings and the hub shell to prevent wheel wobble.

A bushing anti-rotation system and apparatus. A bushing anti-rotation system includes an impeller and diffuser stage including a rotatable shaft extending longitudinally through the stage, the diffuser having an inner diameter defining a bore, a bearing set including a bushing pressed into the inner diameter, and a rotatable sleeve inward of the bushing, and means for wedging the bushing against the inner diameter of the diffuser, wherein the means for wedging provides a mechanical lock against rotation of the bushing. The means for wedging the bushing against the diffuser includes one of a key wedged between an eccentric cavity in the diffuser and a notch in the bushing, a pin protruding from the diffuser against a flattened portion of the bushing, a square-shaped bushing secured into a square-shaped bore, a bent retaining ring having a bent end that wedges against a diffuser groove wall, or a combination thereof.

A composite tubular structure is described suitable for transmitting axial loads in compression or tension. It comprises an elongate composite member 70 having a nut 50 retained in each end for forming a connection with another component. The composite member further comprises an inwardly tapered section at each end, each of which has an inner surface that follows a tapered outer surface of one of the embedded nuts. The inwardly tapered section narrows the composite member in a longitudinal direction towards one end so as to provide a constriction which retains the respective nut within. A connector 80, 84, 86 may clamp the end with a pre-load. A liner 60 may be used to support the nuts during deposition of the filaments in order to form the two inwardly tapered sections at the ends. It can allow the wall of the structure to be formed with different profiles.

In accordance with one aspect of the present disclosure, a rolling element bearing assembly is disclosed. The rolling element bearing assembly may be used in an electrically-assisted turbocharger. The bearing assembly includes an inner race having an outer diameter defining an inner raceway, an outer race having an outer diameter and an inner diameter, the outer-race inner diameter defining an outer raceway, a single row of rolling elements between the inner raceway and the outer raceway, and a squeeze-film damper integrated with the outer race to form a single component. The squeeze-film damper provides for a squeeze-film damper surface between the outer-race outer diameter and a housing.

The invention relates to a bearing assembly (10) comprising at least one first bearing element (12) and a second bearing element (14) which are rotatably connected relative to each other along a common longitudinal axis (14). The bearing assembly (10) comprises a brake device (18) which inhibits the rotation of the two bearing elements (12) relative to each other by means of a frictional force produced by the brake device (18), wherein the brake device (18) has at least one frictional element (20) and at least one clamping device (22), by means of which the frictional element (20) is permanently clamped against one of the two bearing elements (12). The bearing assembly also comprises a coupling device (30) which can be moved between an open state and a closed state. In the closed state, the brake device (18) is engaged, whereby when the two bearing elements (12) rotate relative to each other, the rotation is inhibited by the frictional force produced by the brake device (18), and in the open state, the brake device (18) is disengaged.

A device for producing a releasable clearance-free position of a rolling bearing, having a rolling bearing which has an outer ring, an inner ring mounted on a shaft and a plurality of rolling elements arranged between the inner ring and the outer ring, and having a tensioning device mounted on the circumference of the rolling bearing outer ring for generating a radial preload which is uniform over the outer circumference of the rolling bearing outer ring between the tensioning device and the rolling bearing outer ring, wherein the tensioning device has an axially adjustable tensioning element which can be brought into a first alignment in which the rolling bearing has play, and which can be brought into a second alignment in which the rolling bearing is free of play. A corresponding method is also described.

A mower deck can include roller assemblies that prolong the life of bearings by more evenly distributing the roller's load to the bearings. The roller assembly can include a roller that is secured between opposing bearings via a tapered shaft of the roller and a correspondingly tapered collar that is housed within the corresponding bearing. The interface between the tapered shaft and the tapered collar causes the collar to be secured snugly within the bearing while also providing even distribution of the roller's load to the bearing.

A steering device includes a rolling-element bearing that rotationally supports a rotating member in a housing. The rolling-element bearing includes an inner ring, an outer ring, first rolling elements, and second rolling elements. The first rolling elements and second rolling elements are disposed in parallel in the axial direction between the inner ring and the outer ring. The inner ring includes a first split race having a first inner peripheral track surface and a second split race having a second inner peripheral track surface. The steering device further includes a fixing structure configured to fix the rolling-element bearing to the outer periphery of the rotating member in a state where a load is applied to the first split race, the first rolling element, the outer ring, the second rolling element, and the second split race.
