PACMotion™ Rotary Servo Motors Installation and User Manual
GFK-3169C
2.1.8
Radial force
If the motors drive via pinions or toothed belts, then high radial forces will occur. The permissible values
at the end of the shaft may be read from the diagrams in chapter "Drawings" from (Section 8: Dimension
Drawings). The maximum values at rated speed you will find at the technical data from (➜ # 169). Power
take-off from the middle of the free end of the shaft allows a 10% increase in F
2.1.9
Axial force
When assembling pinions or wheels to the axis and use of e.g. angular gearheads axial forces arise. The
maximum values at rated speed are found in the technical data.
2.1.10
Coupling
Double-coned collets have proved to be ideal zero-backlash coupling devices, combined, if required,
with metal bellows couplings.
2.1.11
Vibration class
The motors are made to vibration class A according to EN 60034-14. For a speed range of 600-3600 rpm
and a shaft center between 56-132 mm, this means that the actual value of the permitted vibration
severity is 1.6 mm/s.
