Abstract: 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.

Abstract: To provide a rolling bearing in which a resin cover for preventing electrolytic corrosion is accurately attached to a bearing ring. The rolling bearing includes: an inner ring and an outer ring that are disposed coaxially with each other; a rolling body that is disposed between the inner ring and the outer ring; and a resin cover that is mounted on the outer ring. The outer ring has an outer circumferential surface that faces an opposite side of the inner ring, and an end surface that faces an axial direction. The resin cover has a circumferential wall portion that covers the outer circumferential surface, and a flange portion that is connected to the circumferential wall portion and covers the end surface. The flange portion has an opening portion formation region that has a constant width in a radial direction, extends over an entire circumference, and is formed with opening portions that expose the end surface.

Abstract: Compressor device provided with at least one compressor element and a drive for the compressor element, wherein all bearings of at least one shaft in the compressor device configured to carry static axial load, are provided with a bearing damper which comprises a coupling element and at least one damping element made of damping elastomer material. The bearing damper is installed with the aid of the coupling element between a bearing of the compressor device and the housing of the compressor device. The coupling element allows little or no movement of the bearing relative to the housing the radial direction compared to the axial direction. The damping element is configured to dampen the axial movement of the bearing relative to the housing.

Abstract: A two-part bearing cage for a rolling bearing includes a first cage part and a second cage part. Each cage part includes an annular base body with a plurality of bars extending axially from the annular base body and/or a plurality of complementarily designed bar receptacles. The bars of one cage part engage in the bar receptacles of the other cage part to form cage bars for defining cage pockets configured to receive the rolling elements of the rolling bearing. Each bar includes a claw and each bar receptacle includes a connection portion such that each connection portion and its corresponding claw form a snap joint.
