Hubs will be fixed like a shrunk-on fit on shafts with the help of taper
adapter sleeves. To assembly and disassembly it you need only a
screw driver DIN 911 (Allan key).
The same set screw or rather the
same screws serve to loose and to stretch.
The taper – adapter sleeve are inside cylindrical, outside cone
shaped and slotted along the length. The smaller sleeves have in the
big face 2 and 3 cylindrical blind holes parallel to the axis. One half
lies on the material of the sleeves and the other half lies in the hub
and have threads.
Set screws or rather screws will be screwed in with a Allan key to the
stop in the face bores. When the screws are powerful tightened, the
hub will be drawn on the shaped sleeve and the sleeve will be
pressed with force on the shaft.
