ABSTRACT:
A method for separating an encoder shaft of an angle encoder from a drive shaft, which are axially aligned with each other along an axial direction and are self-lockingly braced on each other by a press fit along the axial direction and a central fastening screw, which connects the encoder shaft and the drive shaft in the axial direction. A head of the fastening screw rests against an end of a bore of the encoder shaft, which receives a shank of the fastening screw, and a thread of the fastening screw is screwed into an internal screw thread of the drive shaft for bracing the encoder shaft and the drive shaft. The method includes partially turning the fastening screw out of the internal screw thread of the drive shaft and canceling the press fit by generating an axially oriented force acting between the head of the fastening screw and an end of the encoder shaft opposite the press fit.
