Maximum Weights Of The Coupling - Siemens SIMOTICS HV M Operating Instructions Manual

Technical data and drawings
B.2 Maximum weights of the coupling
Applications
The above-mentioned tightening torques apply for the following applications:
● Case A
● Case B
● Case C
B.2

Maximum weights of the coupling

The motor is designed for flexible coupling. If the maximum weight of the coupling is exceeded,
check the feasibility.
Diameter of the shaft exten‐
124
Applies to electrical connections in which the permissible torque is normally limited by the
bolt materials and/or the current carrying capacity of the insulators, with the exception of
the busbar connections in case B.
Applies to bolts screwed into components made from materials with lower property class
(e. g. aluminum) and to bolts with property class 8.8 according to ISO 898-1.
Applies to bolts with property class 8.8, A4-70 or A4-80 according to ISO 898-1, however
only to bolts screwed into components made from materials with higher property class, e.g.
cast iron, steel or cast steel.
Note
Non-standard tightening torques
Different tightening torques for electrical connections and bolted connections for parts with
flat seals or insulating parts are specified in the relevant sections and drawings.
