A shaft comprises two parts. One of these two parts is tube-shaped, and the other is pushed into the tube-shaped part along a main axis. The two parts are fixed to each other for rotation about the main axis and connected to each other in a gliding way along the main axis, by a spline provided between the two parts. One of the two parts comprises a plurality of elongated teeth which are parallel to the main axis and whose cross-sections decrease from the first part towards the second part. Intermediate spaces between neighboring teeth are at least as broad as the teeth. The other of the two parts, at its circumference facing the first part, is made of plastically deformable plastic material, and a counter-profile into which the teeth engage is pressed in the plastic material by intrusion of the teeth during assembly of the two parts. |

1. A shaft comprising a first part and a second part,
wherein one part of the first and the second parts is tube-shaped, and the other part of the first and second parts is pushed into the tube-shaped part in a direction of a main axis, a circumference of the first part facing a circumference of the second part, and wherein the first and the second parts are fixed to each other for rotation about the main axis and connected to each other in a gliding way in the direction of the main axis by a spline provided between the first and the second parts,
wherein the first part, at its circumference facing the second part, comprises a plurality of elongated teeth which are parallel to the main axis,wherein cross-sections of the teeth decrease from the first part towards the second part,wherein, in circumferential direction around the main axis, intermediate spaces between neighboring teeth are at least as broad as the teeth, andwherein the second part, at its circumference facing the first part, comprises a pressed-in counter profile into which the teeth engage, wherein the second part, at its circumference facing the first part, is made of plastically deformable plastic material, and wherein the counter profile is pressed in the plastic material of the second part by intrusion of the teeth of the first part into the plastic material during assembly of the first and second parts. |
