12.2.6 Example (XM, XH or XW conveyors)
You wish to set the clutch so that it permits a maximum traction force
o
f 900 N. Above that load, the clutch should release.
From the table you find that the ring must be released at least 9 divisions
fro
m hand-tightened position. Since the ring should be turned by complete
steps, you should select 9 steps. This corresponds to three quarters (¾) of
a full turn. The clutch will release at approximately 925 N. If you release the
ring by 10 divisions the clutch will release at 875 N.
Also see formulas for chain tension calcu
lations in the main conveyor cat-
alogue, chapter "Multiflexing conveyors", section "Engineering guidelines".
12.3 Start-up
12.3.1 Lubrication
The conveyor chain is lubrication-free. H
owever, for some specific applica-
tions where the operating environment is p
articularly hostile, regular lubri-
cation of the slide rail/conveyor chain will res
ult in a lower coefficient of fric-
tion, longer life and
reduced running costs. Use a silicone-based lubricant
(LDSS 450 or an equivalent lubricant).
