Assembly and servicing of the toothed belt unit
Before you can assemble your new linear unit you must remove any securing devices used in
transport.
4.1
Setting up and servicing the shaft slot
The shaft slot is set by tightening the setting
screws (by means of an Allen key (a)) on the
underside of the shaft slot, proceeding in a cross-
wise manner.
The
desired
prestressing
is
determined
individually according to the shaft slot application.
Stiffness, torque loading, guidance accuracy and
resistance to movement all increase with pre-
stressing. The working life is reduced.
Maintenance:
Shaft slots must be greased via the grease nipple
every 300 hours of operation and in any event
every three months. The grease nipples are on
both sides of the front of the slot. The factory
default setting is designed for the respective tasks
in the relevant product descriptions and describes
an average value for the stress data.
Note:
Pushing on the guide rail is effected by slight forward and backward movement during the delay
movement.
Grease
Sodium grease on a mineral base, recommended ISO viscosity class: ISO-VG 100 (original grease:
transmission grease 4223 from Siebert GmbH). Too high a prestress reduces the working life. Feature:
the shaft slot is diifficult to move and can be difficult to move on the guide rails.
