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.

A planetary gear for a planetary gearset has a gear body and a planetary gear shaft defining a planetary gear rotational axis (APR) of the planetary gear. The gear body includes a gear rim having a first number (n1) of teeth and a second number (n2) of ribs. The ribs extend between the planetary gear shaft and the gear rim, and planetary gear contact projections are arranged on the ribs and project beyond the gear rim along the planetary gear rotational axis (APR). Also disclosed is a planet carrier for such a planetary gear, including an insert for removing torque from the carrier body, which insert is connected to the first disk-shaped body. The first disk-shaped body forms a first free planet carrier face on which a number of reinforcing ribs are arranged.

A method for manufacturing a torque-transmitting assembly includes turning an inner component and machining an outermost surface of the inner component such that the outermost surface of the inner component has a continuous convex shape. The method further includes turning an external component and machining an innermost surface of the external component such that the innermost surface of the external component has a continuous convex shape. The method also includes 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 and placing the heated external component onto the inner component while the inner component is maintained at room temperature.

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. A receiving region (21) is arranged in the hub (20). The end section (11) is arranged in the receiving region (21), with an intermediate layer of the filler material (30) positioned inbetween. The filler material (30) forms undercuts in the axial and rotational direction, in relation to the end section (11) and in relation to the receiving region (21), so as to create a positive embodiment of the shaft-hub connnection (1).

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.
