Technical specifications
For further binding technical specifications and configuring aid
(e.g. lubrication, temperature rise and typical applications),
please refer to the latest catalog supplied by ZF (Zahnradfabrik
Friedrichshafen). The permissible characteristics of the motor
and
the gearbox must be taken into account in the design of the
complete drive unit (motor and gearbox).
For further information, refer to:
With motor 1PH8166-1..2, for example, the rated torque must be
reduced to 300 Nm (221 lb
f
-ft). With motors of shaft height
SH 132, please note that the maximum permissible speed of the
2K 250 gearbox for splash lubrication is 6300 rpm.
Option
K90
with motor shaft diameter 42 mm is also required for
the 2K 250 gearbox.

Selection and ordering data
1)
Higher drive speeds are allowed in some instances (refer to the ZF Catalog)
with oil-cooled gearboxes and for gear ratios
i
= 1.
2)
Special versions, such as gearboxes with different torsional backlash, or
other gear ratios (
i
= 3.17 or
i
= 5.5), are available on request.
3)
Preconditions: DE shaft extension with feather key and full-key balancing.
4)
Preconditions: DE shaft extension with feather key and full-key balancing.
Bearing version for coupling output. Shaft and flange accuracy
tolerance R. DE flange with shaft sealing ring.
Motors with built-on planetary gearbox
The SIMOTICS M-1PH8 motors are also available with a flange-
mounted planetary gearbox. The motor/gearbox unit is function-
tested. The entire drive unit, i.e. the SIMOTICS M-1PH8 asyn-
chronous motor with flanged-on ZF gearbox, can be ordered
directly from Siemens:
The following details must be specified with the order:
