Normally-loaded shaft
In drives with only one direction of rotation
where the stresses in the shaft are moderate,
the shaft can be plain, see Fig. 3. and tables

Mounting instructions
Design of driven shaft end on heavily-
loaded shaft
Where the driven shaft is heavily loaded
and is subject to high stresses, for example
on changes in the direction of rotation, it is
recommended that the driven shaft should
have a stress relieving groove; see Fig. 3.1
and tables 3.1 and 3.4.
If the motor is to work properly it must be
installed with the greatest possible precision.
Every item connected to the motor that does
not meet the requirements of the following
instructions may result in stresses that
adversely affect the service life of the motor.
Normally the motor must be completely filled
with oil. When the motor is installed with the
shaft in the horizontal plane, the drain ports
must be positioned vertically. The higher of the
two drain ports must be used: see fig. 3.5.
When the motor is mounted with the shaft in
the vertical plane, drain outlet D1 or D must
be connected to the drain hole on the shaft
end housing or end cover. A preloaded check
valve must be connected in the drain line to
ensure that the motor is filled with oil; see 3..
"Draining and venting the motor".
The drain line must be dimensioned so that
max. 3 bar (43.5 psi) motor housing pressure
is not exceeded.
The max housing pressure is 3 bar (43.5 psi).
Brief peaks during operation up to 8 bar (116
psi) are permissible. The permitted housing
pressure when the motor is stationary is 8 bar
(116 psi).
The motor must always be connected in such
a way as to give a sufficient boost, make-up
flow at the low pressure connection. This is
particularly important at high speeds and
with rapid reversing, see .1 "Recommended
charge pressure".
