7.4.5 Installation on a gearbox
The installation layout for the axial piston unit on a gearbox is described below.
After installing on a gearbox, the axial piston unit is covered and is difficult to access:
▶
Therefore, before installing, make sure that the centering diameter centers the
axial piston unit (observe tolerances) and that no impermissible axial or radial
forces act on the drive shaft of the axial piston unit (installation length).
▶
Protect the drive shaft against frictional corrosion by providing permanent
lubrication.
▶
Fix the axial piston unit at the installation location.
No gearing forces higher than the permissible axial and radial forces are to act on the
shaft, if necessary the gear wheel must be supported separately at the gearbox output.
7.4.6 Installation with cardan shaft
To be connected around the axial piston unit with a cardan shaft:
1.
Position the axial piston unit close to the specified installation point. It should
allow enough space for the cardan shaft to fit through on both sides.
2.
Join the cardan shaft to the drive shaft of the machine/system.
3.
Push the axial piston unit to the cardan shaft and join the cardan shaft to the
output shaft of the axial piston unit.
4.
Bring the axial piston unit to the installation position and secure. If necessary,
details on the required tools and tightening torque for the mounting bolts can be
obtained from the system manufacturer.
7.4.7 Completing installation
1.
Remove any mounted transport screws.
CAUTIOn! Operation with protection plugs!
Operating the axial piston unit with protection plugs may result in injury or damage
to the axial piston unit.
▶
Before commissioning, remove all protection plugs and replace them with
suitable, pressure-proof, metal threaded plugs or connect the appropriate lines.
2.
Remove the transport protection.
The axial piston unit is delivered with protective covers (1) and protection
plugs (2). They are not pressure-resistant and have to be removed prior to
connection. Use a suitable tool for this to prevent damage to the sealing and
functional surfaces. If sealing or functional surfaces are damaged, contact your
Bosch Rexroth service partner or the service department of the manufacturer's
plant for the axial piston unit.
