A magnetic geared rotary electric machine includes: a casing; a stator which includes a stator core, a coil, and a stator magnet provided inside the stator core; a first rotor which includes pole pieces provided inside the stator; a second rotor which includes a rotor core provided inside the first rotor and rotor magnets provided in the rotor core at intervals in a circumferential direction; movable bearings which are provided in the casing so as to be arranged at intervals in the circumferential direction and which come into contact with at least one of outer peripheral surfaces of the first rotor and the second rotor; and actuators which move the movable bearings in a direction included in a plane orthogonal to an axis.

A flexible cartridge assembly can include a flexible shell that includes a flexible portion disposed between a compressor-side portion and a turbine-side portion, where the flexible portion includes a series of arc-shaped cutouts disposed axially along at least a portion of the flexible portion; a compressor-side bearing assembly; and a turbine-side bearing assembly.

A drive (1) with a housing (2) and a toothed part (4) which is mounted rotatably relative thereto with a wire race bearing (15), wherein a threaded ring (23) is screwed onto the housing (2) or the toothed part (4), said threaded ring axially fixing the wire race bearing (15) and permitting an adjustment.

A seal assembly for a truck wheel hub assembly includes an inner annular case having an axial portion disposable about an axle and a radial portion extending radially outwardly from the axial portion. An outer annular case is coupleable with a hub bore and has a radial portion extending radially inwardly from the bore. An annular elastomeric seal member has a base portion disposed on the outer case and at least one flexible axial seal lip with a first end integrally formed with the base portion and a second, free end sealingly engageable with the radial portion of the inner case. A radial projection extends radially inwardly from the outer case radial portion and has an inner radial end located adjacent to and spaced radially outwardly from the inner case axial portion or an outer circumferential surface disposed about the axle so as to form a labyrinth seal gap.

A wheel bearing assembly with an outer race, a first roller bearing, a second roller bearing, a first shield, and a second shield. The outer race may have a first inner surface and a second inner surface. The first roller bearing and the second roller bearing may have a plurality of rollers configured to engage with the first inner surface and with the second inner surface, respectively. The first shield and the second shield may be configured to engage with the first roller bearing and the second roller bearing, respectively, and push the first roller bearing and the second roller bearing against the first inner surface and the second inner surface, respectively. The first shield and the second shield may each have a rubber seal configured to reduce passage of fluid into or out of the first roller bearing and the second roller bearing, respectively.

A lock nut and tang washer mechanism preloads and locks components in a rotating environment. A drive system mechanism preloads and locks the device in a rotating environment and provides a double locking safety requirement needed in most aircraft for applications operating in an enclosed environment. The mechanism holds a required torque for the duration of the drive system operating life without the need for periodic visual inspections.

A seal assembly is for a wheel hub assembly and includes an inner annular case disposable about an axle and having a radial portion extending radially outwardly from the axle. An outer annular case is coupleable with a hub bore and has a radial portion extending radially inwardly from the bore. An annular elastomeric seal member has a base portion disposed on the outer case and at least one flexible axial seal lip with a first end integrally formed with the base portion and a second, free end sealingly engageable with the radial portion of the inner case. The lip extends generally axially and radially outwardly from the first end to the second end such that the lip is biased radially outwardly by centrifugal force during rotation of the hub to reduce sealing pressure of the lip second end on the inner case radial portion.

A sealing device configured to be mounted on a rolling bearing provided for a wheel bearing device, the wheel bearing device including an axle pipe and a rolling bearing being fitted onto an outer circumferential stepped portion formed on an outer circumference of the axle pipe to rotatably support a wheel, the sealing device being mounted between an outer ring and an inner ring. The sealing device includes a slinger member having a first cylindrical portion, a disk portion, and a second cylindrical portion; a core body member having a cylindrical portion and a disk portion; and a seal body made of an elastic material. An inner circumferential face of a seal body cylindrical portion has an inclined portion constituting a labyrinth of which diameter gradually increases toward one side from the other side in the axial direction between the inner circumferential face and the second cylindrical portion.

A power steering device includes a bearing rotatably supporting the tip side of a worm shaft, a gear case provided with the housing hole for housing the worm shaft and a holder housing the bearing. The holder includes a first holder holding the bearing, a second holder having the guide part configured to guide a movement of the second bearing toward a worm wheel, and a spring provided in a compressed state between the first holder and the second holder and configured to bias the first holder toward the worm wheel. The second holder includes a holder opening part configured to allow the bearing and the first holder to pass through thereof in the guiding direction of the guide part to guide the bearing, and the first holder faces an inner peripheral surface of the housing hole through the holder opening part.
