Assembly of stators without housing
Bosch Rexroth AG R911336703_Edition 03
The machine manufacturer must observe the special features of
the construction and create a special assembly instruction for the
motor components rotor and stator. The machine manufacturer's
mounting instructions are the only binding guidelines.
WARNING
⇒The permanent magnets at the rotor and the resulting magnetic forces can
cause the rotor to be abruptly pulled into the stator. Therefore, fasten the ma‐
chine housing to the work table and only use lifting gear (e.g. crane with
hoisting chains) which avoids uncontrolled movements of the rotor package
while it is lowered into the stator.
Avoid
●
jamming or clamping the housing while mounting it to the
machine.
●
damaging the centering collar on the housing and the ma‐
chine.
●
In general, the stator has to be connected to the machine via
all mounting holes.
●
All screwed connections are equipped with a liquid screw
lock. 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.
●
Use screws of the fastening class specified in the dimension
sheet. 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
"Mounting screws with tightening torque" on page
Assemble the stator according to the specifications of the machine manufac‐
turer. The machine manufacturer has to consider the special character of his
construction and has to prepare special mounting instructions.
For general orientation, the MBT project planning manual
sambly instruction. The example of a MST530 describes a schematic con‐
struction without considering the special structural features of the machine
and serve only for general orientation. The dimension sheets also show parts
that are required but are maybe not included in the Bosch Rexroth delivery
and have to be appropriately dimensioned and provided by the user.
General procedure during disassembly: The motor components lie on a clean
and a flat surface.
1. Check whether the components are damaged. Damaged components
must not be mounted.
