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.
Clamp the coupling hub onto the drive shaft or ensure permanent lubrication
2.
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.
Install the coupling on the output shaft of the drive motor in accordance with the
specifications 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.
9.
For bell housing installation, check the coupling axial play through the bell
window according to the manufacturer's specifications.
10.
Details on the required tools and tightening torques for the mounting bolts are
available from the machine/system manufacturer.
11.
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.
