Shaft-hub-connection

The shaft-hub-connection comprising:

• a hub;
• a first front face and a second front face arranged parallel to the first front face on said hub;
• a first through bore in said hub extending between the first and second front faces and centered on a longitudinal axis, said first through bore having a first bore portion;
• a support disk having a second through bore, said support disk being non-movably positioned along the longitudinal axis of the hub at the end of the first bore portion close to the second front face;
• a shaft having an external face portion formed fitting to the first bore portion of the hub, said shaft being centered on the longitudinal axis;
• a threaded bore in said shaft starting at a front face of the shaft and centered on the longitudinal axis;
• a tensioning screw having a head and a threaded shank, said tensioning screw being screwed into the threaded bore starting from the second front face of the hub through the second through bore of the support disk, and a nut non-rotatably retained on the threaded shank between the support disk and the front face of the shaft with a gap formed relative to the support disk;
• and
• wherein the first bore portion of the hub and the external face portion of the shaft received in the first bore portion, being formed such that at least, starting from a specific insertion depth of the shaft into the first bore portion, a frictional resistance and/or a resistance resulting from the shape of the external face portion and the first bore portion acts to oppose tensioning of the external face portion and the first bore portion.
