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.
