Permissible Forces On The Motor Shaft - HEIDENHAIN TNC 410 M Technical Manual

7.12 Permissible Forces on the Motor Shaft

7.12.1 General Information
7 – 196
All diagram values given for permissible axial and radial forces on the motor
shafts apply for the nominal bearing life, depending on the specific motor.
In the diagram the nominal bearing life values are specified for the maximum
permissible forces.
Axial forces
Point of the axial force
As shown in the diagrams, the maximum permissible axial force may also
depend on the motor speed.
Radial forces
Point of the radial force
The maximum permissible radial force may also depend on the motor speed
and the point of the radial force on the motor shaft. The point of the force is
defined by the distance z and is shown as an axis in the load diagrams.
