Mounting the stator
Bosch Rexroth AG R911298798_Edition 08
Stators which have already been ordered with a housing according to the mo‐
tor type code can be mounted to the machine directly via the mounting holes
in the flange.
When configuring the screwed connection, observe the data in the dimension
sheet referring to the quantity and size of the flange mounting holes.
●
In general, the stator has to be connected to the machine via
all mounting holes.
●
All screwed connections have to be provided with a liquid
screwlock. See also
●
The necessary screw length for fastening the stator depends
on the machine construction.
●
The screwed connections has to be able to take up both the
force due to the weight of the motor and the forces acting
during operation.
Ensure cleanliness during all working steps!
Refer to the instruction on how to prepare mounting in
chanical assembly" on page
1.
Lift and position the stator on the machine via suitable lifting tools and
the lifting eye bolt on the stator housing.
Avoid...
●
jamming or clamping the housing while mounting it to the
machine,
●
damaging the centering collar on the housing and the ma‐
chine.
2.
Center the stator housing on the machine using the centering collar pro‐
vided on the housing. Because of the enormous torque development of
the motors, all of the mounting holes on the motor flange must always
be used to fasten the motor.
An exception are frame sizes 530B, 530C and 530E where at least the
two outer mounting holes must be used per quarter hole circle diameter
on the motor flange.
Use screws with property class 8.8 or higher.
The property class of the screws and the hardness category of
the washers has to be equivalent in order to transmit the required
tightening torques (see
