Installation
Bosch Rexroth AG, RE 90300-B/2021-01-19
4.
Transport the axial piston unit to the installation location.
5.
Remove dirt and foreign particles from the installation location.
6.
Install the coupling onto the input or output drive according to the instructions
of the coupling manufacturer.
Do not fasten down the axial piston unit until the coupling has been correctly
installed.
7.
Fasten the axial piston unit at the installation location.
8.
Align the drive shaft of the axial piston unit and the output shaft of the drive
motor or the input shaft of the machine so that there is no angular deviation.
9.
Make sure no excessive axial and radial forces are acting on the drive shaft.
10.
For bell housing installation, check the coupling axial play through the bell
window according to the manufacturer's specifications.
11.
Details on the required tools and tightening torques for the mounting bolts are
available from the machine/system manufacturer.
12.
When using elastic couplings, check that the drive does not resonate after
completing the installation.
7.4.5 Installation on a gearbox
The following describes how to install the axial piston unit on a gearbox.
After installing on a gearbox, the axial piston unit is covered and is difficult to access:
▶ Before installing, make sure that the spigot diameter centers the axial piston unit
(observe tolerances) and that no excessive axial or radial forces are acting on the
drive shaft of the axial piston unit (installation length).
▶ Protect the drive shaft against frictional corrosion by providing permanent
lubrication.
▶ Fasten the axial piston unit at the installation location.
No gearing forces higher than the permissible axial and radial forces should act on
the shaft; if necessary, support the gear wheel at the gearbox output separately.
7.4.6 Installation with cardan shaft
The following describes how to connect the axial piston unit to the drive motor with
a cardan shaft.
NOTICE!
Damage to the axial piston unit and leaks at the shaft seal due to
incorrectly installed cardan shaft!
Improperly installed cardan shafts generate unbalances. This results in vibrations
and excessive forces on the drive shaft.
▶ Observe the cardan shaft manufacturer's assembly instructions.
1.
Position the axial piston unit near the intended installation location.
Allow enough space for the cardan shaft to fit through on both sides.
2.
Place the cardan shaft on the output shaft of the drive motor.
