A method for manufacturing an assembled camshaft for valve-controlled internal combustion engines, in which at least one cam disc with a base circle region and cam region is machined on the running surface and has a cam-disc recess, includes shrinking the cam disc onto a corresponding shaft designed with a defined dimensional overlap by cooling the shaft and heating the cam disc. Temporally before being shrunk onto the shaft, the at least one cam disc is clamped by a clamping device such that a tension force acts on the recess wall region, which defines the cam-disc recess, the tension force corresponding to a predetermined extent to the state of stresses and/or deformation state of the recess wall region after the operation of shrinking the cam disc onto the corresponding shaft. The running-surface machining of the at least one cam disc takes place when the cam disc is clamped by the clamping device.

A rotational driving force transmission mechanism includes a cylindrical shaft made of fiber reinforced plastic, and a first constant velocity joint. The shaft is joined to the first constant velocity joint via a metallic intervening member which is attached to one end of the shaft in the axial direction. The intervening member includes a shaft portion and a main body portion. The shaft portion is inserted into the one end of the shaft from a distal end side thereof. The main body portion is of a bottomed tubular shape made up from a bottom part joined to a proximal end side of the shaft portion, and a tubular portion fitted over the one end of the shaft. The first constant velocity joint includes an inner ring fitted externally over the tubular portion of the intervening member.

A freewheel assembly includes a central axis of rotation, a single-piece flange formed by deep drawing, and a freewheel unit. The single-piece flange includes a sleeve portion, a disk portion protruding radially outward from the sleeve portion, and a centering collar. The disk portion includes a first end face and the centering collar is formed on the first end face. The freewheel unit includes an outer ring fastened to the sleeve portion by press fitting, and a plurality of rolling elements accommodated within the outer ring. The outer ring includes a plurality of clamping ramps, and each one of the plurality of rolling elements cooperates with a one of the plurality of clamping ramps.

A method of making an axle sleeve includes forming a main body comprising a cylinder and forming an expansion member whereby a diameter of the main body may be varied. The method includes cutting an inner helical cutout comprising a first slit defined through the main body and extending helically from an inner edge of the main body, cutting an outer helical cutout comprising a second slit defined through the main body and extending helically from an outer edge of the main body, forming an inner edge remaining portion comprising an annular section of the main body unbroken by the inner helical cutout, and forming an outer edge remaining portion comprising an annular section of the main body unbroken by the outer helical cutout.

A vehicle includes a first drivetrain component and a second drivetrain component. The first drivetrain component defines a splined orifice. The second drivetrain component has a shaft that includes splines that are configured to clearance-fit the splined orifice upon engagement up to a first length and interference-fit the splined orifice upon engagement beyond the first length. Engagement of the splines and the splined orifice at substantially the first length counteracts loads perpendicular to an axis of the shaft preventing disengagement of the first and second drivetrain components.

A method for assembling a camshaft from a support shaft and components to be connected to the support shaft, the components having through-openings for receiving the support shaft. In this method, a support shaft is provided, having first diametrical enlargements in first regions, in which the components are to be secured, and second diametrical enlargements in second regions, in which the components are to be pre-positioned. A diameter (D2) in the second regions is smaller than a diameter (D1) in the first regions The support shaft is cooled and/or the components are heated up, so that the support shaft can be pushed with its first and second diametrical enlargements through the through-openings of the components.

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.

The present invention relates to a transmission input shaft arrangement (100) for a vehicle transmission, the transmission input shaft arrangement comprising an input shaft (102); a clutch arrangement (104) and a bearing arrangement (106) arranged at a position spaced apart from the clutch arrangement (104). The bearing arrangement (106) comprises a bearing inner ring (108) rotationally connected to the clutch arrangement (104).

The present invention relates to a motor vehicle rotary electric machine (100) drive assembly, the drive assembly comprising a rotor shaft (2) extending along a longitudinal axis (X) and a connecting piece (4) providing connection between the shaft and the torque transmission system comprising a bore (41) for the passage of the rotor shaft, the drive assembly being characterized in that the bore comprises a first wall (41a) extending axially and a cylindrical second wall (41b) extending axially in alignment with the first wall, and in that the rotor shaft comprises: —a first surface (21) extending axially and cooperating with the first wall of the bore to centre the connecting piece around the rotor shaft; and—a second cylindrical surface (22) extending axially and provided with knurling, with a diameter (A) greater than the diameter (A′) of the second wall of the bore, the connecting piece being force-fitted onto the rotor shaft by means of the knurling.

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.
