A device for positioning a shaft relative to a functional element including at least one hub for the shaft. The device may include a tailstock for axially aligning the shaft with respect to the at least one hub of the functional element. The tailstock may include a radially adjustable centring cone for the shaft. The tailstock may have an outer diameter that is smaller than an inner diameter of the at least one hub.

An assembly for securing a probe retention member at a desired location within a tubular interior such as in a drill string collar. The assembly may use one or more securing members external to the retention member. In some embodiments most of the stresses from the probe retention structures of the retention member are isolated.

A method for jointing elements, each having a cutout, on a shaft by a device for producing a control shaft, comprises disposing the elements vertically above one another, aligned, and fixed. The method also comprises pushing the shaft in vertically from above though the cutouts of the elements by a traversable guide carriage of the device and displacing by a pneumatic piston of the device the traversable guide carriage and the shaft attached thereto until a maximum first press-in force is reached. The method further comprises displacing by at least two spindles of an electric spindle drive of the device the traversable guide carriage and the shaft when the maximum first press-in force is exceeded.

In order to provide a brake disc unit the production and assembly of which is economically viable even with extreme mechanical and thermal load capacity, preferably without the application of intermediate elements, the disclosure proposes a brake disc unit with a friction ring and a friction ring carrier which are connected by a shaft-to-hub connection with an alignment gearing having a multitude of dogs, wherein the cross-section of the dogs provides a contour which, at least partly, runs along an extended trochoid.

A heat treatment method is provided in which a first steel component (11) formed with a coating (111) thereon is fitted in first holes (123, 124) of a second steel component (12) subjected to a quenching treatment. The heat treatment method includes a heating step of heating the second steel component to a first temperature (T.sub.1) equal to or higher than a tempering temperature (T.sub.0) of the second steel component and higher than a temperature of the first steel component by a temperature difference (ΔT) for achieving shrink fitting and a shrink-fitting step of shrink-fitting the first steel component in the first holes of the second steel component in a state of maintaining the temperature difference for achieving shrink fitting between the first steel component and the second steel component.

A drive shaft has a tubular member extending between axial ends and being hollow. The tubular member is formed of a thermoplastic matrix with embedded fibers. At least one ring member is positioned radially of the tubular member. A method is also disclosed.

A method for manufacturing a torque-transmitting assembly includes: turning an inner component (b) machining an outermost surface of the inner component such that the outermost surface of the inner component has a continuous convex shape; (c) turning an external component; (d) machining an innermost surface of the external component such that the innermost surface of the external component has a continuous convex shape; (e) heating the innermost surface of the external component to expand a size of the innermost surface after machining the innermost surface of the external component; (f) placing the heated external component onto the inner component while the inner component is maintained at room temperature; and (g) holding the inner component and the external component in place until an interface between the innermost surface of the external component and the outermost surface of the inner component reaches the room temperature.

A connection device for a joint shaft in a motor vehicle includes an axis of rotation, a first connection area for connecting the connection device to a drive train element, a predetermined breaking region, and a tube region which connects directly to the predetermined breaking region. The connection device has an axial extension in the direction of the axis of rotation, and a radial extension orthogonal to the axis of rotation and is designed, at least substantially, as a tubular hollow body. The predetermined breaking region is arranged between the first connection region and the tube region in the axial direction. A connection area is arranged in the axial direction between the first connection region and the predetermined breaking region.

A camshaft phaser includes a stator, a rotor rotatable with respect to the stator, and a connector configured for being nonrotatably fixed to the rotor. The connector is configured for being nonrotatably connected to an outer circumferential surface of a camshaft.
