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:
▶
Therefore, before installing, make sure that the spigot diameter centers the axial
piston unit (observe tolerances) and that no impermissible axial or radial forces
act 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 are to act on
the shaft, if necessary the gear wheel must be supported separately at the gearbox
output.
7.4.6 Installation with cardan shaft
The following describes how to connect the axial piston unit via a cardan shaft on
a drive motor.
nOTICE! Damage to the axial piston unit and leaks at the shaft seal!
Improperly installed cardan shafts generate unbalances. This results in vibrations
and impermissible forces on the drive shaft.
▶
Observe the cardan shaft manufacturer's assembly instructions.
1.
Position the axial piston unit close to the specified installation location. Allow
enough space for the cardan shaft to fit through on both sides.
2.
Position the cardan shaft on the output shaft of the drive motor.
3.
Push the axial piston unit to the cardan shaft and position the cardan shaft on the
drive shaft of the axial piston unit.
4.
Bring the axial piston unit to the installation position and secure. If necessary,
details on the required tools and tightening torque for the mounting bolts can be
obtained from the system manufacturer.
7.4.7 Completing installation
1.
Remove any mounted transport screws.
CAUTIOn! Operation with protective plugs!
Operating the axial piston unit with protective plugs may result in injury or damage
to the axial piston unit.
▶
Before commissioning, remove all protective plugs and replace them with
suitable, pressure-resistant, metallic threaded plugs or connect the appropriate
lines.
