Abstract

In a shaft fixture in which a toothed and especially knurled region (B) of a shaft (2) is pressed into a drilling (3) in a seat (4) to form a positive fit with great centric precision via two separate centering sections (A, C), the solidity of the fixture is to be increased in that the shaft has a toothed region (D) outside the section to be introduced into a securing drilling. This toothed region may in particular be a pinion (1) which is pressed via a shaped shaft (2) with a hurled region (B) into a seat drilling (3) to provide a positive fit. To this end the end sections of the gaps between the teeth in the pinion region (D) can terminate in the adjacent shaft region (C) so that the diameter of the shaft may be made larger in relation to that of the pinion than if the sections did not so terminate.
