A clamping mechanism for securing a hollow shaft on a solid shaft, the hollow shaft having, at least one of its ends, an inner cone for receiving an adapter bushing that has a corresponding outer cone and rests on the solid shaft; and the adapter bushing having an axial longitudinal slot; and a contraction disk, including at least one pressure ring, exerting a contraction force on the hollow shaft with the aid of the at least one pressure ring; and the pressure ring having an axial longitudinal slot.

Clamping mechanism

A series of shafts configured to attach in a bore of a receiving part and a method for manufacturing the shafts, the series including at least two different sizes, each size including different variants of shafts; wherein each shaft includes at least five contiguous axial regions, wherein each variant includes different gear teeth in the axial region of the first end of the shaft. The bore in the receiving part includes at least three axially adjacent regions, the axial regions being arranged to provide a force-locked connection between the shaft and the receiving part when the shaft is pressed into the receiving part and such that the toothed or milled region of the shaft cuts into the bore in a form-locked manner as a result of the shaft being pressed in.
