ATTENTION! Damage to encoders, bearings and shafts due to improper assembly!
Never use force when
mounting drive elements with fittings, e.g. hitting drive elements, shafts or the motor or gear unit housing with a hammer,
and instead install them in accordance with the instructions in the documentation.
Prerequisites
§
The drive element does not cause any impermissible shaft loads (e.g. tensioning the belt on a belt drive). Information
on permissible shaft loads can be found in the corresponding catalog (see
).
§
The drive element is balanced.
§
The tolerance of the inner hole of the drive element corresponds to ISO H7.
§
The keyway of the drive element corresponds to DIN 6885-1 (if not otherwise specified).
§
The information in the chapter
§
A mounting device suitable for the drive element is available (not included in the scope of delivery).
Procedure
1.
Remove the corrosion protection from the solid shaft.
2.
Degrease the inner hole of the drive element.
3.
Mount the drive element on the solid shaft with the aid of a mounting device positioned on the centering hole of the
solid shaft. Details can be found in the following figure and table.
4.
If the drive element is difficult to hoist, do not use force and instead heat it to about 80 °C beforehand.
5.
If the length of the solid shaft is greater than the length of the drive element, use an appropriate spacer bushing that
you position between the plate (1) and drive element (5).
