Abstract
In the case of a shaft coupling for bottom cylinders of drafting units on spinning machines, a shaft is provided on its end with an area of a reduced diameter which engages in a longitudinal bore at the end of the other shaft. In the area of the longitudinal bore, the two shafts are connected with one another by means of a screw thread. In addition to the screw thread, the area of the reduced diameter also comprises two centering surfaces with fits, one fit being a clearance fit and the other fit being a press fit. As a result, radial deviations of the shafts caused by the shaft coupling are to be avoided.
