1. Remove protective cap (1), if available.
2. Check machine shaft:
–
Diameter in fit tolerance h6
–
Material yield point Re > = 360 MPa
–
E−module approx. 210000 MPa
–

–
Concentricity in order to prevent unnecessary additional forces caused by
tensioning.
3. Thoroughly clean and
degrease
hollow shaft bore and machine shaft.
Note!
Thoroughly degrease the bore over the
entire
hollow shaft length to
make sure that remainders of the anticorrosion agent will not be carried
off into the area of the shrink disc when pushing on the machine shaft.
4. Slightly loosen clamping screws (2) one after the other, do
not
unscrew!
5. Push drive onto machine shaft.
6. Slightly tighten clamping screws manually.
7. Tighten clamping screws (2) one after the other (see Fig. 14) in several passes,
with rising torque, evenly until the indicated screw−tightening torque (see Tab. 6 )
is reached at all screws.
