Axial Force - Siemens Simodrive 1PH7 Planning Manual

2.3.2

Axial force

The maximum axial forces F
following force diagrams.
The force diagrams and tables are only valid for standard drive shaft ends; non-
standard drive shaft end dimensions are specified for each particular application
corresponding to the permissible forces.
For force levels going beyond these, please contact your local Siemens office.
Shaft heights 180 and 225: For coupling, belt or pinion out-drive with straight
teeth, generally, only low axial forces occur. The locating bearing is adequately
dimensioned so that these forces can be accepted in all mounting positions.
The following forces due to the weight of the drive-out element are permissible at
the shaft end in order to ensure perfect vibration characteristics (i.e. low vibration):
S SH 180: max 500 N
S SH 225: max. 600 N
For pinion out-drives with helical gearing, please contact your local Siemens office.
Note
The permissible axial force at the shaft end without taking into account the
alignment forces of the rotor weight, the mounting position as well as the force
direction.
Information regarding axial force stressing, refer to the Planning Guide
"AC Induction Motors, General Section".
