Purpose/Assembly/Cleaning/Lubrication
Purpose
The toothed belt feeds LEZ1/2/3/9 are provided
for positioning devices, workpieces, tools etc. The
maximum possible load on the slots is dependent
on the acceleration. Toothed belt feeds are avail-
able in different
lengths, with and without drive module.
Assembly
isel toothed belt feeds LEZ1/2/3/9 are prefabri-
cated units (optional). complete with drive motor.
Cleaning
The toothed belt feeds LEZ1/2/3/9 are open units.
Clean the feed regularly to remove dust and
swarf. No objects (e.g. swarf) should be allowed
to build up under the toothed belt and inside the
section or to bond to the steel shaft.
Basic lubrication
Toothed belt units LEZ1/2/3/9 are fully lubricated
ex works and can be used immediately.
Only the two steel shafts (3) require regreasing in
accordance with the following notes, using the
grease nipple (1) on the shaft slots (2). All bear-
ings and drive components are greased fior life
and require no further regreasing.
Greasing
Use an impact press (4) or hand greasegun (5)
for greasing. Approx. three strokes on the isel
push-type gun (4) equals 1 g of grease. Use the
grease nipple (1) on the front of the shaft slot (2)
for greasing.
Proceed as follows:
1. Clean the steel shaft (3) and the grease nipple
(1) to remove dirt and solid bodies if necessary.
2. Place the grease gun on the clean grease nip-
ple (1) and force one stroke of grease in.
3. Move the shaft slot (2) to and fro several times
to distribute the grease introduced.
4. Continue to add grease and distribute it until
the desired amount is introduced.
Greasing plan
Regularly check the film of grease along both
steel shafts for dry points and dirt, and regrease
as necessary.
When idling or under average loads, you should
regrease approximately every 300 hours of oper-
ation with a sodium grease GP00/00F-20 to
DIN51502 or a comparable grease (part no.:
299031).
Greasing for toothed belt unit with trolley
On delivery, the steel shafts and rollers are pre-
served with oil, which should not be removed if
the parts are not dirty. Rollers based on twin-row
deep groove ball bearings are sealed for life.
Always look for an even film of grease on the
running surface of steel shafts. For this, regrease
steel shafts with GP00/00F-20 grease to DIN
51502 (part no.: 299031)
or a comparable grease.
Dry running is possible, but leads to increased
wear, friction corrosion and significantly lower
working life.
Risk of crushing
Ensure there is adequate protection
against crushing in operation!
Please note that if excessive force is used,
the grease nipple (1) can be pressed out of
the plastic threaded guide.
