A method for producing a shaft-hub connection in which a shaft component and a hub component are placed into a joined state in the form of a frictional shaft-hub connection. The shaft component has a toothed region having teeth with a height H, and the hub component has a mating toothed region having a mating region internal diameter d. The hub component is pushed onto the shaft component in a longitudinal direction to produce the frictional shaft-hub connection and in the process geometrically reproduces the toothed region in the mating toothed region. The mating toothed region passes over a cylindrical centering region with an outer diameter D before coming into contact with the toothed region. The outer diameter D is at most 0.2 mm and at least 0.005 mm smaller than the mating region inner diameter d. The centering region has a length L greater than 1 mm.

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 tube arrangement includes a composite tube defining a centerline axis, wherein the composite tube comprises a proximal surface and a distal surface, and an end fitting comprising a first end disposed within the composite tube and a second end extending from the composite tube, wherein an outer surface of the end fitting defines a flared portion defining a terminus of the first end, a lobe portion disposed axially from the flared portion, and a terminating portion disposed axially from the lobe portion, the proximal surface conforms to a geometry of the outer surface of the end fitting, the lobe portion and the flared portion mechanically lock the end fitting to the composite tube to mitigate movement of the end fitting relative to the composite tube.

The invention relates to a shaft-hub connection (1), particularly for mounting a rotor wheel on a shaft (10). The shaft-hub connection (1) comprises a shaft (10), a hub (20) and a filler material (30). The shaft (10) comprises an end section (11) on one end.
