A low-noise main bearing cap for an internal combustion engine is designed that includes a main bearing cap body, wherein the main bearing cap body is connected to an engine body main bearing seat. The main bearing cap body is provided with a vibration isolator A vibration isolation structure is provided between the main bearing cap body and the vibration isolator The main bearing cap body is connected with the vibration isolator through a connector The vibration isolation structure comprises an S-shaped structure and an oil film gap, and the vibration isolator is provided with an oil inlet passage which is communicated with the oil film gap. The present design solves the control problem of the main bearing vibration source caused by the main bearing load.

Multistage centrifugal compressor provided with a shaft with blades, which is mounted in a housing with bearings. At least one bearing is provided with a bearing damper element including a ring arranged between the shaft and the bearing. The ring includes slots through the thickness of the ring in the axial direction (X-X′) and at a distance from the radially-directed inner and outer surface of the ring. The slots are at least partially overlapping, and: A) the slots are filled with a liquid, and the axial annular surfaces are closed off by means of a protective cap; or: B) at least one of the annular surfaces is provided with a viscoelastic material or hysteretic damping material sandwiched between two concentric discs, which discs are attached to the ring; or: C) the slots are filled with a viscoelastic material.

The disclosure relates to a steering system for a motor vehicle, which is designed as a steer-by-wire steering system and comprises a rack, an electric drive for longitudinal displacement of the rack, a worm gear and a drive shaft which is in toothed engagement with the rack. The electric drive is connected to the drive shaft by the worm gear so as to transmit torque.

A pivot bearing arrangement for a steering column of a motor vehicle, having a steering shaft which is rotatably mounted in a casing unit in the direction of its axis of rotation but rigidly mounted in the radial direction, is improved in terms of a simple and cost-effective construction in that the casing unit is provided with at least one first sliding bearing shell, which comprises a first circumferential radial projection, which engages in a first circumferential groove.

An apparatus for delivering a flow of gas having: a controller; a housing defining a gas-flow passage flowing a high concentration oxygen gas; a motor with windings, resilient bearing mounts and an impeller to deliver the gas through the gas-flow passage; a flexible printed circuit electrically connecting the motor to the controller and sensor system; and an elastomeric shield to pneumatically isolate the windings from the gas-flow passage.

A fluid bearing for a wind turbine including a bearing housing, a plurality of bearing pads inside the bearing housing and circumferentially distributed around a longitudinal axis of the fluid bearing, a plurality of supporting structures, each supporting structure having at least a first interface detachably connected to a respective seat provided in the bearing housing and at least a second interface detachably connected to a respective bearing pad of the plurality of bearing pads, the supporting structure including an elastomer allowing tilting of the respective bearing pad parallel to the longitudinal axis, the elastomer being interposed between the respective seat and the respective bearing pad is provided.

An apparatus includes an outer bearing member defining a cavity and an inner bearing member disposed within the cavity. The inner bearing member includes a spherical surface and a rod attachment opening defined in the spherical surface. The apparatus also includes an elastomeric material disposed within the cavity adjacent to the spherical surface.

The bearing component comprises an external cylindrical member having an outer bearing surface and an inner cavity, and internal cylindrical member, arranged in the inner cavity of the external cylindrical member and substantially coaxial thereto. The external cylindrical member and the internal cylindrical member form a gap therebetween. A resilient damping feature is arranged in the gap.

A pivot bearing arrangement for a steering column of a motor vehicle, having a steering shaft which is rotatably mounted in a casing unit in the direction of its axis of rotation but rigidly mounted in the radial direction, is improved in terms of a simple and cost-effective construction in that the casing unit is provided with at least one first sliding bearing shell, which comprises a first circumferential radial projection, which engages in a first circumferential groove.

A telescopic steering column assembly comprises a telescopic shroud having an inner shroud portion and an outer shroud portion, and a telescopic steering shaft that passes through the shroud, comprising an inner shaft portion and an outer shaft portion. The telescopic steering shaft is supported by the shroud through a support assembly interposed between the outer shaft portion and the inner shroud portion, which in use, limits or removes free play between the telescopic steering shaft and the shroud that would otherwise occur in at least one direction orthogonal to the telescopic movement.
