Installation 27/68
RE 92105-01-B/06.2017, A4CSG, Series 3x,
Bosch Rexroth AG
7 Installation
Prior to installation, the following documents must be to hand:
• Installation drawing for the axial piston unit (can be obtained from your contact 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 92105 for the axial piston unit (contains the permissible technical data)
7.1 Unpacking
The axial piston unit is delivered in a corrosion protection film made of polyethylene
material (PE).
CAUTIOn!
Danger from parts falling out!
Improperly opening the packaging can result in parts falling out, which can become
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 material according to the national regulations in your
country.
7.2 Installation conditions
The installation position and position of the axial piston unit essentially determine
the procedures during installation and commissioning (such as when filling and air
bleeding the axial piston unit).
▶
Fix the axial piston unit so that the expected forces and torques can be
transferred without any danger. The machine/system manufacturer is responsible
for dimensioning the fasteners.
▶
Observe the permissible radial forces on the drive shaft when driving with radial
loading (belt drives). If necessary, the belt pulley must be stored separately.
▶
Make sure that the axial piston unit is air bled and filled with hydraulic fluid
during commissioning and operation. Do this also after relatively long standstill
periods, since the axial piston unit may drain through the hydraulic lines.
▶
The leakage in the housing area must be directed to the reservoir via the highest
drain port. Use the line size which is appropriate for the port.
▶
A check valve in the drain line is only permissible on a case-by-case basis upon
request. Please consult your responsible contact person at Bosch Rexroth.
▶
To achieve favorable noise values, decouple all connecting lines from all vibration-
capable components (for example, reservoir) using elastic elements.
▶
Make sure that the suction, drain, and return lines flow into the reservoir below
the minimum fluid level in all operating conditions. This will prevent air from
being drawn in and foam from being formed.
