Important
When designing the complete drive unit (motor with gear) the gearbox data is
decisive.
For 1PH4168 AC motors, for example, the rated torque must be reduced to
300 Nm. For motors, shaft heights 100 and 132, the maximum motor speed
should be limited to the permissible gearbox speed 2K120 / 2K250.
Other binding technical data and engineering information/instructions (e.g.
lubrication, temperature rise, permissible cantilever forces and examples), please
refer to Catalog 2K Gearboxes from ZF (Zahnradfabrik Friedrichshafen).
1) Can be supplied with holding brake (option).
2) Higher maximum speed from 8000 ... 9000 rpm for more than 20% power–on duration is only possible
with injection lubrication.
3) Permissible with gearbox oil cooling for gearbox stage i = 1.
