Provided is a rack bush capable of reducing an effect on the feeling of a steering operation. A rack bush (1) comprises: a rack bush 1 housed in a cylindrical housing (4), which supports a load applied to a rack bar (5) while allowing movement of the rack bar (5) in the direction of the axis (O) and can be freely expanded and contracted in the radial direction; and elastic rings (3) mounted on the bush body (2). The bush body (2) has mounting grooves (28), which are formed in the circumferential direction on an outer peripheral surface (22) for mounting the elastic ring (3). An axis (P) of the mounting groove (28) are shifted from the axis (O) of the bush body (2). By this arrangement, there are formed an elastic ring protruding part (10), where the elastic rings (3) protrude greatly from the outer peripheral surface (22) of the bush body (2), and an elastic ring embedded part (11), where the elastic rings (3) are embedded in the outer peripheral surface (22) of the bush body (2).

A method for producing a bearing, in particular a hydraulic axle support bearing, which comprises the following steps: preassembling an inner part in an outer part with an elastomer body which is arranged in between and is reinforced by a plastic cage which at least partially bears against an inner wall of the outer part. The plastic cage is configured to radially protrude over an upper edge and a lower edge of the out part and, at the lower edge of the outer part, to project over the latter. Simultaneously calibrating the outer part and the plastic cage by constricting the outer part and the plastic cage from a respective first diameter to a respective second diameter which is smaller than the respective first diameter. After the constriction, the plastic cage projects over the upper edge of the outer part for the form-fitting axial securing of the outer part.

A drive device (1) for motorized actuation of a functional element of a motor vehicle has an electric motor (2) with a motor shaft (3) and also has a worm shaft (4) of a worm gearing. A first end of the worm shaft is connected to the motor shaft (3) and a second end is received in a radial bearing (5). The radial bearing (5) has a bearing body (21) with an outer surface mounted in a housing (11) and at least one annular bearing element (24) is mounted to the worm shaft (4). The bearing element (24) is elastic at least in a partial region to ensure compensation for tolerances in the region of the radial bearing.

There is provided an apparatus for delivering a flow of gas having a controller, a housing defining a gasflow passage, a motor with an impeller to deliver gas through the gasflow passage, and a flexible printed circuit electrically connected to the motor for electrically connecting the motor to the controller. There is also provided an apparatus for delivering a flow of gas having a housing defining a gasflow passage. The gas flowing through the gasflow passage is a high concentration oxygen gas. The apparatus has a motor with windings and an impeller to deliver gas through the gasflow passage, and an elastomeric shield to pneumatically isolate the windings from the gasflow passage.

A bearing holder includes an inner portion and an outer portion, wherein the inner portion includes a receiving contour for receiving the bearing and the outer portion is configured to be mounted on a housing. A transition area between the inner portion and the outer portion includes a spring. The transition area is at least partly in a plane perpendicular to an axial axis of the receiving contour and is at least partly in a plane with at least one part of the inner and the outer portion. The transition area includes an attenuator and the attenuator is configured to attenuate a vibration of the inner portion to reduce a transfer of the vibration from the inner portion to the outer portion. Further, an electric motor, a method for producing a bearing holder and a method for operating a bearing holder are described.

A rubber-metal sleeve bearing includes an outer sleeve having a first outer edge and a second outer edge in opposing relationship to the first outer edge, when viewed in an axial direction. The first and second outer edges each have at least one section provided with radially inwardly recessed outer edge regions. An inner sleeve is disposed in concentric relation to the outer sleeve, and an intermediate sleeve is disposed concentrically between the outer and inner sleeves and connected to the outer sleeve via a first elastomer layer and to the inner sleeve via a second elastomer layer.

The bearing assembly includes one or more elastomeric members loaded in a precompression by a shim that includes a shape memory alloy. The shape memory alloy is configured to generate the precompression in the elastomeric members upon a temperature change.
