Clockwise
The direction ofrotation asindicated onthe name plate determines thedirection
ofrotation oftheaxial piston unit asviewed onthe drive shaft; see chapter 5.3
"Product identification" onpage 22. For information onthe direction ofrotation
ofthedrive motor, please refer tothe drive motor manufacturer's
instructionmanual.
7.4.2 Dimensions
For standard versions, thedata sheet contains all required installation dimensions
aswell astheposition and dimensions oftheconnections. If necessary,
aninstallation drawing can berequested.
Also observe themanuals provided bythemanufacturers oftheother
hydrauliccomponents when selecting therequired tools.
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.
