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.
Diesel drives with a small number of cylinders and low flywheel mass are at
particular risk.
Do not use a belt drive the A4VSO ATEX due to the buildup of static electricity.
• A cardan shaft on the input or output drive of an axial piston unit 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.
• For combinations of multiple units and for single pumps, make sure that the
respective case pressure in each unit is not exceeded. In the event ofpressure
differences atthe drain ports ofthe units, the shared drain line must bechanged
so that the minimum permissible case pressure ofall connected units isnot
exceeded inany situation. If this is impossible, separate drain lines must be laid
ifnecessary (see also chapter8).
• Excessive case pressure or excessive pressure peaks can cause wear, leaks
and excessive temperatures in the shaft seal, creating a risk of sparks
(seealsochapter2.6 "Product-specific safety instructions" on page 11).
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
• With 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.
