A hydrodynamic slide bearing (10, 10′) supports a shaft (14, 14′) that is mounted rotatably. The hydrodynamic slide bearing (10,10′) comprises a plurality of bearing segments (12, 12′) arranged next to one another in the rotation direction (22, 22′). The segment surfaces together form a running surface (16, 16′) for the shaft (14, 14′). At least one bearing segment (12, 12′) has a plurality of grooves (26, 26′) disposed in its segment surface, and the grooves (26, 26′) are orientated substantially transverse to the rotation direction (22, 22′). The rear groove edges (261) in the rotation direction (22, 22′) are orientated obliquely to their respective assigned radial plane (24, 24′) and are undercut in relation to their respective assigned radial plane (24, 24′). The front groove edges (262) in the rotation direction (22, 22′) are not undercut and are orientated obliquely to their respective assigned radial plane (24, 24′).

The present invention provides an adjustable bearing assembly comprising a first bar and a second bar. The first bar comprises a first engagement surface which is configured to engage with a second engagement surface on the second bar. The first bar further comprises a bearing surface opposite the first engagement surface. One of the first or second engagement surfaces comprises a first plurality of teeth aligned in a first direction, wherein the plurality of teeth are configured to engage a plurality of inclined surfaces on the other of the first or second engagement surfaces such that a force applied to the second bar in the first direction causes the distance between the bearing surface and the second bar to vary.

Radially outer ring of a bearing unit for a hub-wheel assembly for motor vehicles, the radially outer ring being provided with: a flange portion having a plurality of axial fixing holes that connect an element of the motor vehicle wheel to the radially outer ring, an almost cylindrical portion which with part of its radially internal surfaces defines raceways for rows of rolling bodies of the bearing unit, an axially internal or axially external surface of the flange portion and a radially external surface of the cylindrical portion connected to each other by a first portion of toroidal surface (St1) and of a second portion of toroidal surface (St2) defined by corresponding first radius (R1) and second radius (R2), a truncated cone surface (Stc) defined by an angle (a) formed with a rotation axis (X) of the radially outer ring is interposed between the first portion of toroidal surface (St1) and the second portion of toroidal surface (St2).

In a propeller shaft, a crowning portion of a male spline portion is provided in a predetermined range including a front end portion in an axial direction, and a tooth tip surface is shaped in such a manner that a tooth thickness thereof gradually increases from the front end portion toward an intermediate portion of the male spline portion in the axial direction.

A bearing housing is configured as an end-side cover for a nacelle of a fluid-flow power plant and includes a cylindrical section having an interior and a bearing unit in the interior. The bearing unit includes at least one rolling-element bearing having an inner ring and an outer ring rotatably disposed with respect to each other about a bearing rotational axis and a plurality of rolling elements between the rings. A pressure line of the bearing intersects the bearing rotational axis at a first angle. An angled section of the housing extends from the cylindrical section of the housing at a second angle that is related to, and preferably substantially equal to, the first angle.

A steering actuator for rear axle steering of a motor vehicle has a spindle drive (5) which comprises pushrods (9) which are connected to a threaded spindle (16) and which are mounted in a housing (6) by means of plain bearings (18), allowing the passage of air, and are connected at each end thereof to an attachment element (12) provided for coupling to a chassis suspension arm, wherein a gaiter (19, 20) is connected on the one side to the housing (6) and on the other side to one of the attachment elements (12) in each case. Each plain bearing (18) is designed as a bearing allowing one revolution of the threaded spindle (16), wherein at least one longitudinal groove (21) abuts one guide bush (23) of the plain bearing (18).

A bearing housing is configured as an end-side cover for a nacelle of a fluid-flow power plant and includes a cylindrical section having an interior and a bearing unit in the interior. The bearing unit includes at least one rolling-element bearing having an inner ring and an outer ring rotatably disposed with respect to each other about a bearing rotational axis and a plurality of rolling elements between the rings. A pressure line of the bearing intersects the bearing rotational axis at a first angle. An angled section of the housing extends from the cylindrical section of the housing at a second angle that is related to, and preferably substantially equal to, the first angle.

A bearing assembly includes a rolling bearing having a bearing ring fitted to a mating member, i.e., a shaft or a housing, with a clearance fit. Of the bearing ring and the mating member, the bearing ring has a flank face that separates a fitting surface of the bearing ring across the entire width thereof. The flank face defines a radial gap between the bearing ring and the housing. In a load receiving region where the radial gap remains, a portion of the bearing ring which is deformed in a wave-shaped pattern is kept out of contact with the fitting surface of the housing. The wave-shaped deformation of the bearing ring does not act as traveling waves that cause creep of the bearing ring.

A bearing device, a compressor and a method, in which a first radial bearing element is measured in at least the radial direction, an axial distance of the first axial bearing element from the first radial bearing element being measured, the second radial bearing element being measured in at least the radial direction, the first radial bearing element being positioned with respect to the second radial bearing element as a function of the predefined first width of the radial gap, the adjustment arrangement being situated in such a way that the axial gap has the predefined second width.
