Bosch Rexroth AG, A10VO, A10VSO Series 31, RE 92701-01-B/04.2018
7 Installation
Have the following documents on hand before installation:
• Installation drawing for the axial piston unit (can be obtained from your contact
person at Bosch Rexroth)
• Hydraulic circuit diagram for the axial piston unit (in the installation drawing)
• Hydraulic circuit diagram for the machine/system (available from the machine/
system manufacturer)
• Order confirmation (contains the order-related technical data for your axial piston
unit)
• Data sheet for the axial piston unit (contains the permissible technical data)
7.1 Unpacking
The axial piston unit comes in a polyethylene (PE) corrosion protection film.
CAUTIOn! Danger from parts falling out!
Improperly opening the packaging can result in parts falling out, which can be
damaged or cause injury!
▶
Place the packaging on a level, load-bearing surface.
▶
Only open the packaging from the top.
▶
Remove the packaging from the axial piston unit.
▶
Check the axial piston unit for transport damage and completeness; see chapter
4 "Scope of delivery" on page 18.
▶
Dispose of the packaging in accordance with the regulations in your country.
7.2 Installation conditions
The installation position and location of the axial piston unit essentially determine
how it is installed and commissioned (such as when filling and air bleeding the axial
piston unit).
▶
Install the axial piston unit so that the expected forces and torque can be
transferred without any danger. The machine/system manufacturer is responsible
for sizing the fasteners.
▶
Observe the maximum permissible radial forces on the drive shaft when
transferring drive/output drive with radial loading (belt drives). If necessary, store
the belt pulley separately.
▶
Make sure the axial piston unit is always filled with hydraulic fluid during
commissioning and operation. Also do this also after relatively long standstill
periods, since the axial piston unit may drain out through the hydraulic lines.
▶
Direct the leakage in the housing to the reservoir through the highest drain port.
Use a line size that matches the port.
▶
A check valve in the drain line is only permissible on a case-by-case basis following
consultation. Please consult your proper contact person at Bosch Rexroth.
▶
To keep noise levels low, use elastic elements to isolate all connecting lines from
all vibration-capable components (e.g. reservoir).
▶
Make sure the suction, drain, and return lines flow into the reservoir below the
min. fluid level under all operating conditions. This will prevent air from being
drawn in and foam from forming.
