Installation With A Coupling - Bosch rexroth HS5E Instruction Manual

Installation | A4... with HS5E(V)(L) control system Series 1x and 30
• On the drive of an axial piston unit, a cardan shaft may cause vibrations and
impermissible rotary angular accelerations. Depending on the frequency and
temperature, this may cause leaks in the shaft seal and damage the rotary group.
• If a shared drain line is used for several units, make sure that the respective case
pressure in each unit is not exceeded. The shared drain line must be dimensioned
to ensure that the maximum permissible case pressure of all connected units is
not exceeded in any operating condition, particularly at cold start. If this is not
possible, separate drain lines must be laid if necessary.
The version of installation for the axial piston unit depends on the connecting
elements to the drive side. The following descriptions explain the installation of the
axial piston unit:
• With a coupling
• On a gearbox
• On a cardan shaft
7.4.4 Installation with a coupling
The following describes how to assemble the axial piston unit with a coupling:
NOTICE!Danger from improper handling!
Product can be damaged!
▶ Do not assemble the coupling hub on the drive shaft of the axial piston unit by
striking it.
1. Assemble the specified coupling half on the drive shaft of the axial piston unit
according to the instructions of the coupling manufacturer.
The drive shaft of the axial piston unit is equipped with a female thread. Use this
female thread to pull the coupling element onto the drive shaft. The size of the
female thread can be seen in the installation drawing.
2. Clamp the coupling hub onto the drive shaft or ensure permanent lubrication
of the drive shaft. This prevents the formation of frictional corrosion and the
associated wear.
3. Transport the axial piston unit to the installation location.
4. Remove dirt and foreign particles from the installation location.
5. Assemble the coupling on the output shaft of the drive motor in accordance with
the parameters provided by the coupling manufacturer.
Do not fasten down the axial piston unit until the coupling has been correctly
installed.
6. Fasten the axial piston unit at the installation location.
7. Align the drive shaft of the axial piston unit and the output shaft of the drive
motor so there is no angular deviation.
8. Make sure no excessive axial and radial forces are acting on the drive shaft.
