A method for connecting a constant velocity joint having a bell and a shaft to a wheel bearing having an opening, the shaft being oversized relative to the opening, includes applying an adhesive to the shaft and/or the opening, the adhesive in an uncured state being configured to reduce a coefficient of friction between the shaft and the opening, pressing the shaft into the opening to form a press connection between the shaft and the wheel bearing, and curing the adhesive or allowing the adhesive to cure. Also a subassembly formed by the method.

A differential gear including a rotatably mounted differential housing and a final driven gear mounted rotationally fixed to the differential housing. The differential housing, on the outer circumferential surface thereof, includes two mating surfaces and that the final driven gear, on the inner circumferential surface thereof, includes two radially opposite mating surfaces. The mating surfaces formed on the outer circumferential surface of the differential housing and the mating surfaces formed on the inner circumferential surface of the final driven gear are each designed as separate mating surfaces which, when viewed in axial direction (a), are arranged geometrically separated from each other by a spacing.

A compressor assembly is provided. Embodiments of the present disclosure generally relate to compressors used in chiller air conditioning systems for indoor spaces. The disclosed compressors have magnetic bearings that support rotating components. In one embodiment, the compressor comprises a partially segmented thrust bearing stator core. Additional systems, devices, and methods are also disclosed.

In a component for connecting a shaft to a clamping holder that can receive a rotor, the clamping holder is able to be inserted into a cup-shaped housing and is able to be fixed there by fasteners. On the housing base of the housing is a connector for connecting the housing to the shaft in a torque-proof manner. The fasteners are arranged with their base surface on the outer lateral surface of the housing, and can be brought into engagement with the clamping holder by bores present in the housing. The fasteners have at least one recess in the base surface, such that they rest with their base surface on the outer lateral surface only in some regions.

A rotary assembly for an aircraft engine is disclosed. A shaft is mounted for rotation about a central axis and a rotary part is mounted on the shaft for common rotation therewith. The rotary part has an axial end portion extending away from a center of mass of the rotary part, the axial end portion having a radial thickness smaller than that of the rotary part at an axial location aligned with the center of mass. The shaft and the rotary part have an interface defining an interference fit between the shaft and the axial end portion of the rotary part. The interface is located at a distance along the central axis from the center of mass. An undercut is defined in the rotary part. The undercut extends axially from adjacent the interface towards the center of mass.

A shaft connection, e.g., for a motor vehicle driveline, comprises a metal shaft tube material and a metal connecting element. The connecting element comprises a connecting portion with an outer toothing which is pressed with a press fit into a connecting portion of the shaft tube so that an interlocking connection effective in the circumferential direction is formed for torque transmission, wherein the connecting element comprises a maximum outer diameter in the region of the outer toothing; wherein the shaft tube comprises an axial connecting region which is formed radially inwardly into a section of the connecting portion that is reduced relative to the outer toothing so that an interlocking axial connection effective in the axial direction is formed between the shaft tube and the connecting element for transmitting axial forces. A drive shaft can have such a shaft connection.

A composite vehicle driveshaft is provided with a crash collapse system that allows for a controlled longitudinal collapse of the driveshaft by facilitating telescopic movement of various components with respect to each other during a crash event. The crash collapse system may include a collapsible joint with a sleeve that is concentrically bonded in an end of a composite tube and a stub end assembly that is spline-engaged and interference fit within the sleeve, such as by way of a press-fit and/or a thermal shrink-fit procedure. This relationship may rotationally lock and axially fix the stub end assembly to the sleeve unless, during a crash event, the composite vehicle driveshaft experiences a compression or push-type force that exceeds a minimum breakaway or collapse force value that longitudinally and telescopically collapses the composite vehicle driveshaft.

A rotary assembly for an aircraft engine is disclosed. A shaft is mounted for rotation about a central axis and a rotary part is mounted on the shaft for common rotation therewith. The rotary part has an axial end portion extending away from a center of mass of the rotary part, the axial end portion having a radial thickness smaller than that of the rotary part at an axial location aligned with the center of mass. The shaft and the rotary part have an interface defining an interference fit between the shaft and the axial end portion of the rotary part. The interface is located at a distance along the central axis from the center of mass. An undercut is defined in the rotary part. The undercut extends axially from adjacent the interface towards the center of mass.

A method of manufacturing a torsion bar for a steering system is provided. The method includes supporting a torsion bar blank on a cold forming machine with a plurality of dies at a first end region of the torsion bar blank and a second end region of the torsion bar blank. The method also includes rolling the torsion bar blank to form an end region having a cylindrical outer surface extending from an axial end surface and a serrated portion disposed proximate the end region and axially offset from the axial end surface.

A stop collar for mounting to a downhole tubular includes: a cylindrical housing having a threaded inner surface and a tapered inner surface; a compressible slip ring having teeth formed in an inner surface thereof and a pair of tapered outer surfaces; a compressible cam ring having a tapered inner surface; and a cylindrical bolt having a threaded outer surface. A natural outer diameter of each ring is greater than a minor diameter of the threaded surfaces. Screwing the threaded surfaces of the housing and the bolt is operable to drive the tapered surfaces together, thereby compressing the slip ring such that the teeth engage a periphery of the tubular.
