Siemens SIMOTICS S-1FK2 - Output Coupling

5.3 Output coupling
NOTICE
Motor damage caused by rotating forces
Output couplings, especially sti󹪜 metal bellows-type couplings can exercise rotating forces on
the shaft. These forces can result in bearing motion and in turn damage the motor.
• Rotating forces are not permissible.
To achieve optimum output characteristics, we recommend ROTEX
Ⓡ
GS couplings from the KTR
company.
The advantages of ROTEX
Ⓡ
GS couplings are as follows:
• 2 to 4x torsional sti󹪜ness of a belt gearbox
• No teeth meshing (when compared to a belt gearbox)
• Low moment of inertia
• Good closed-loop control response
KTR can provide support when selecting the coupling, see http://www.ktr.com
