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.
Place 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.
3.
Push the axial piston unit to the cardan shaft and place the cardan shaft on the
drive shaft of the axial piston unit.
4.
Bring the axial piston unit to the installation position and fasten it. Details
of the required tools and tightening torque for the mounting bolts can
be obtained from the system manufacturer.
