RE 92050-01-X-B1/2019.08.23, Axial piston variable pump A4VSO, BoschRexrothAG
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.
2. Clamp thecoupling hub onto thedrive shaft orensure permanent lubrication
ofthedrive shaft. This prevents theformation offrictional corrosion and
theassociated wear. Moreover, this prevents relative movement which could
cause heat or sparks to form.
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. Use the shaft collar as a stop for the coupling. The coupling should not grind
on stationary parts. When using elastic couplings, maintain an air gap to the
case so that no sparking can occur through material contact. When using elastic
couplings, make certain that a sufficiently large air gap to the case is present,
even during operation.
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:
▶ Therefore, before installing, make sure the spigot diameter centers the axial
piston unit and that no excessive 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.
▶ Maintain a sufficiently large air gap between the coupling and the case so no
sparking or heat buildup can occur through material contact.
▶ Fasten theaxial piston unit attheinstallation location.
