Maintenance schedule
Note
Please take special care during all maintenance and repair that the guiding surface
remains intact!
WHEN
WHAT
ACTION
After commissioning
Sliding carriage
Check free movement of the sliding carriage by manually
moving the sliding carriage.
(Check)
(see on page 17)
every 4 weeks or every 1000 km*
Sliding carriage
Check sliding carriage play and replace sliding blocks if
necessary.
(Exchange wearing parts)
(see on page 17)
Check free movement of the sliding carriage by manually
moving the sliding carriage.
(Check)
(see on page 17)
semi-annually or every 5000 km
Toothed belt
Visual inspection of the toothed belt for wear. Change
toothed belt if necessary.
(Check toothed belt)
(see on
*With the first set of sliding blocks (new LCB) please check the sliding carriage play
weekly or every two weeks, as an increased wear can be expected during the initial
break-in phase.
3.3
Check free movement of the sliding carriage
Move the sliding carriage manually over the entire stroke distance after assembly
or setup. The sliding carriage must move easily and with constant force. If the
sliding carriage does not move easily or rather "joltily", please check the following:
Make a visual inspection of the guiding. Check for visual wear and for
smoothness of the guiding surface. If necessary, replace profile. If the force
needed to move the sliding carriage changes continually (increases or decreases
continually), an alignment error of the double-axis actuator could be the case.
New alignment of double axis
(see on page 13).
Possibly too high deflection of the guiding profile. If needs be,
reduce distance
between supports
(see on page 11).
If the causes mentioned above do not apply, please check the sliding carriage
play
(check sliding play)
(see on page 18).
3.4
Replacement interval for wearing parts
Check sliding carriage / play of sliding carriage
The diagrams "Bearing capacity of sliding carriage / wear" show the wear of the
sliding blocks in an ideal case of load on the sliding carriage. The wear can differ
from the indicated curves in a specific application.
Depending on the load and the distance traveled, the sliding blocks in the sliding
carriage wear down and the sliding carriage play will increase accordingly. If the
increased sliding carriage play does not have a negative influence on the
application, the sliding blocks can be operated up to the wear limit (0.5 mm wear
for LCB040 and 1.0 mm wear for LCB060).
The wear limit given in the diagrams may under no circumstances be exceeded -
this could damage the surface of the guiding irreversibly!
