7.4.3 General instructions
Follow these general instructions when installing the axial piston unit:
• Note that certain installation positions will affect the control system. Gravity,
dead weight and case pressure can cause minor characteristic shifts and changes
inresponse time.
• Torsional vibrations and speed variations may cause leaks inthe shaft seal and
increased rotary angular acceleration oftherotary group oftheaxial piston unit.
Atrisk are diesel drives with asmall number ofcylinders and low flywheel mass
and toothed belt orV-belt drives. Belts can lose much oftheir pre-charge pressure
after just ashort operating time.
An automatic clamping device can lessen the speed variations and vibrations, and
thus avoid subsequential damage.
– When using drives with toothed belts orV-belts, always use anautomatic
clamping device.
• On the drive ofanaxial piston unit, acardan shaft may cause vibrations
and excessive rotary angular acceleration. Depending onthe frequency and
temperature, this may cause leaks inthe shaft seal and damage the rotary group.
• If ashared drain line isused for several units, make sure that the respective case
pressure ineach unit isnot exceeded. The shared drain line must bedimensioned
toensure that the maximum permissible case pressure ofall connected units
isnot exceeded inany operating conditions, particularly atcold start. If this isnot
possible, separate drain line must belaid, ifnecessary.
The type ofinstallation for the axial piston unit depends onthe connecting elements
tothe drive side. The following descriptions explain the installation oftheaxial
piston unit:
• With acoupling
• On agearbox
• On acardan shaft
7.4.4 Installation with acoupling
The following describes how toinstall the axial piston unit with acoupling:
NOTICE! Danger from improper handling!
Product can bedamaged!
▶ Do not install the coupling hub onthe drive shaft oftheaxial piston unit
bystriking it.
1. Install the specified coupling half onthe drive shaft oftheaxial piston unit
according tothe instructions ofthecoupling manufacturer.
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.
3. Transport the axial piston unit tothe installation location.
