5.2.4 Mounting the motor on a gear unit with MB adapter
The assembly of a motor on a gear unit with an MB motor adapter with brake is described in a separate document (see
Supporting documents [}5]).
5.3 Mounting drive elements on a solid shaft
This chapter describes the assembly of drive elements, such as hubs, belt drives, couplings, pinions or sprockets, on the
output of a gear unit with a solid shaft and feather key.
When mounting drive elements on a solid shaft without a feather key, observe the technical documentation of the drive
element in question.
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 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 Additional documentation [}12]);
§ The drive element is balanced;
§ The tolerance of the inner hole of the drive element is ISO H7;
§ The keyway of the drive element corresponds to DIN 6885-1 (if not otherwise specified);
