Bearing arrangement with a bearing having an outer bearing race; a machine element with a cylindrical cutout receiving and securing the outer bearing race; and a circumferentially constructed groove adjoins a first axial side of the cylindrical cutout and extends radially outward to receive a locking element for securing the outer bearing race at the first axial side of the groove; an annular locking element having an inner diameter which is larger in a mounting state than in a securing state. The locking element is partially guided in the constructed circumferential groove to secure the outer bearing race at the first axial side in the securing state; and a securing device cooperates with the locking element to secure a changed state of the locking element; and the securing device secures the locking element from an outer side of the machine element opposite the first axial side of the cylindrical cutout.

A cover for a bearing housing, in particular intended to be mounted on machinery for the food industry, provided with an end wall transverse to an axis of the bearing housing; with an annular side wall which extends transversely with respect to the end wall; and with an engaging portion towards the bearing housing, which is formed on one end of the side wall opposite to the end wall; a through-opening being formed through the end wall so as to allow the passage of a moving shaft, preferably a rotating shaft, and being surrounded by a reinforcing ring rigidly joined to and integral with the end wall so as to support a sealing element mounted on the through-opening and sealingly engaged by the moving shaft.

A gear unit for a motor vehicle including a rotatable worm gear shaft rotating about a rotation axis and cooperating with a worm gear wheel in an engagement region spaced from the rotation axis. A pivotable rotary bearing mounts the worm gear shaft on a housing on one side of the engagement region and a loose rotary bearing, pretensioned in the direction of the spacing axis, mounts the other side in the housing. A support device supports the pivotable rotary bearing on the housing in the direction of the rotation axis. To optimize engagement between a worm gear shaft and a worm gear wheel, the pivotable rotary bearing pivots relative to the housing about a pivot axis perpendicular to the rotation axis and to the spacing axis. A support point of the support device is offset relative to the rotation axis along the spacing axis towards the engagement region.

A lock for use with an assembly is provided. The assembly includes an inner race having a bore with a generally tapered periphery. The bearing assembly supports a shaft. The bearing lock includes a sleeve having a generally cylindrical internal periphery adapted for cooperation with the shaft and a generally tapered external periphery that cooperates with the bore. The sleeve conforms from a first condition whereby the internal periphery defines a first diameter to a second condition whereby the internal periphery defines a second diameter different than the first. The bearing lock also includes a collar that cooperates with the sleeve to urge the sleeve from the first condition to the second condition. The collar conforms from a first condition whereby the generally cylindrical internal periphery defines a first diameter to a second condition whereby the internal periphery defines a second diameter substantially different than the first.

An object of the present invention is to hold a holding member appropriately in a casing. A rotary electric machine includes a rotor having a drive shaft, a stator provided on an outer periphery of the rotor, a bearing B2 that rotatably supports the drive shaft, a holding member that contains an aluminum alloy member and holds the bearing, and a casing that houses the rotor, the stator, the bearing, and the holding member. The casing is made of a member that does not grow permanently or an aluminum alloy member that is permanently grown when the holding member is fixed to the casing. The holding member is in a state before permanent growth before being fixed in the casing, and the holding member grows permanently to be fixed more firmly to the casing.

A rotary machine includes a fixed internal body, a rotating external body and a lubrication system to lubricate one or more components of the internal body or external body during rotation. The lubrication system includes: an inlet conduit for a lubricant, formed in the internal body; one or more distribution conduits for the lubricant; a lubricant collection chamber between the external body and the internal body; and an outlet conduit communicating with the collection chamber.

A structural subassembly which has a bearing which comprises a statically arranged outer ring and a rotatably arranged inner ring, wherein the inner ring is connected for conjoint rotation to a component that is rotatable about a longitudinal axis or said inner ring forms part of such a component, and wherein the longitudinal axis defines an axial direction of the bearing. The structural subassembly furthermore comprises a housing flange of a support structure, to which flange the statically arranged outer ring is connected. Provision is made for the outer ring to be of two-part design, wherein each part of the outer ring has a connecting element which is connected to the housing flange, wherein the housing flange is arranged between the two connecting elements in the axial direction.

A system for an unmanned aerial vehicle can include an altitude control system, which further includes a compressor assembly, a valve assembly, and an electronics assembly. The compressor assembly may include a driveshaft and a bearing assembly configured to rotate the driveshaft. The driveshaft may be formed from a first material and a compressor housing may be formed from a second material. The first and second materials may have different rates of thermal expansion. A dynamic preloading mechanism, such as a flexible plate, may be provided within the compressor assembly to exert a preloading force on the bearing assembly. Throughout the duration of the flight of the unmanned aerial vehicle, the preloading mechanism can continually compensate for differences in rates of thermal expansion between the first and second materials throughout.

A hobby servo block system for increasing the load-bearing capacity of a hobby servo motor is provided. The system includes aa servo plate configured to receive a hobby servo motor. The system also includes a hub plate configured to couple to the servo plate such that the hub plate and the servo plate are substantially perpendicular. The system further includes a ball bearing plate configured to couple to the hub plate such that the ball bearing plate and the servo plate are substantially parallel.

A bearing assembly includes a bearing unit configured to support a rotatable component relative to a stationary component which may be a bearing carrier, the bearing unit including a stationary bearing ring and a rotatable bearing ring. The rotatable bearing ring is connectable to the rotatable component and the stationary bearing ring is connectable to the bearing carrier such that they are rotationally fixed. At least part of the bearing unit is not covered by the bearing carrier.
