Selecting the
gear unit
Check the input
power at the gear
unit (P
n
)
The values in the selection tables refer to an input speed of n
e
= 1750 rpm. The input
power at the gear unit corresponds to a maximum torque at the input side. If the speed
deviates, convert the input power by means of the maximum torque.

Determine the gear unit type
↓
Determine the gear unit size by means of the
• maximum output torque (T
a max
)
• Gear ratio (i)
in the gear unit selection tables with adapter AM
↓
Check the maximum permitted overhung load value on the output (F
Ra
)
↓
Check the maximum permitted input power at the adapter (P
m
)
(see “Power ratings, mass moments of intertia” on page 60)
↓
Is the required adapter size available?
↓
Is the required combination feasible?
