INTERVAL
DESCRIPTION OF CHECK
After first 100 hours
or 2 weeks, and every
500 hours or 2 months
thereafter
Stop the sorter, inspect the chain for proper lubrication, and monitor the chain
elongation.
1.
The chain should have a light coat of oil visible on its surface
2.
If the chain is dripping with oil, the oiler flow rate is too high and may be
reduced to prevent the contamination of slats and product with excess oil
3.
Some oil dripping and accumulation is normal at both ends of the sorter
4.
If the chain is excessively dirty or coated in dust/grit: clean it with kerosene
or another appropriate solvent and run the oiler for two chain revolutions
immediately on restarting the sorter
5.
Remove one set of connecting links for inspection: the pin surface will be
shiny and coated in lubrication if it is getting enough oil.
a.
The presence of red or brown residue, or a scored or galled pin surface
means the chain is not getting enough oil: check for proper operation of
the oiler
b.
If the oiler is functioning correctly, increase the oil flow and/or increase
the frequency of oiling as necessary to keep the chain properly
lubricated
6.
Monitor the chain on both sides for elongation: maximum acceptable
elongation is 1.5% before the chain must be replaced
a.
Measure 12 pitch lengths center-to-center: 15-1/4
” maximum
measurement (measurement on a new chain would be 15”)
b.
Chains on both sides of the sorter must be replaced at the same time
c.
Uneven elongation is a warning that one side is not getting enough oil
(chain that is starved for oil will wear faster)
6 months or 3000
hours
Check the oil level and oil condition in the drive motor gearbox. Top up or change
the oil if needed. See the SEW Eurodrive Gear Unit Assembly and Operating
Instructions for detailed instructions on oil replacement and service intervals.
