Assembly of taper clamping sleeve:
Clean the contact surfaces of the taper clamping sleeves and of shaft and hub and afterwards apply thin fluid oil
lightly (e. g. Ballistol Universal oil or Klüber Quietsch-Ex).
The taper clamping sleeves have got axially parallel, cylindrical and smooth tapped blind holes. Only half of these
holes are located in the material of the sleeve. The other half located in the hub has got threads.
Fit the coupling element and the taper clamping sleeve into each other, make sure that the bores cover each
other and tighten the setscrews lightly. Fit the coupling element along with the taper clamping sleeve on the shaft
and tighten the setscrews at the tightening torque specified in table 10.
During the screwing operation the hub is mounted onto the taper sleeve and thus the sleeve is pressed onto the
shaft. By light blows of the hammer the taper clamping sleeve must be pushed further into the taper bore by
means of a suitable sleeve. Afterwards re-tighten the setscrews at the tightening torque specified in table 10. This
process must be performed at least once.
After operation under load of the drive for a short while please inspect if the setscrews have unscrewed.
Axial fixing of the Taper Lock hub (coupling hub with taper clamping sleeve) is obtained by proper assembly only.
!
If used in potentially explosive atmospheres the setscrews to fasten the taper clamping
sleeves have to be secured against working loose additionally, e. g. conglutinating with
Loctite (average strength).
Taper clamping sleeves used without a feather key are not permitted in potentially explosive
atmospheres and are thus not provided with a respective explosion protection marking.
!
Oils and greases with molybdenum disulphide or high-pressure additives, additives of
Teflon and silicone as well as internal lubricants reducing the coefficient of friction
significantly must not be used.
