Lubrication Systems
SPLASH LUBRICATED UNITS —
Standard Type GHB, Y, YB &
YBX drives are splash lubricated. The lubricant is picked up by the
revolving elements and distributed to all bearings and gear meshes.
OIL PUMPS —
Occasionally gear drives are equipped with oil
pumps, either for special lubrication
considerations or for external cooling.
When so equipped, run the
lubrication system for several minutes
to fill the system components. Verify
that the pump is circulating oil
properly then recheck the oil level.
Before starting the gear drive, rotate
the input shaft by hand to check for
any obstruction. Then start the drive and allow it to run without
a load for several minutes. Shut down and recheck oil level.
Add oil to compensate for cooler, filter, etc., oil capacities. If
everything is satisfactory, the drive is ready for operation.
CAUTION
:
Consult the Factory for drives that use pumps to
distribute lubricants with temperatures below 30
°
F(-1
°
C).
Bearing & Seal Greases
Some gear drives have one or more grease lubricated bearings
and grease purged seals. Whenever changing oil in the drive,
grease the bearings and purge the seals with one of the NLGI
#2 greases listed in
Some of these greases are of the EP type and may contain toxic
substances not allowed in the food processing industry. A grease
that meets the USDA “H1” classification is suitable for food
processing applications.
GREASE LUBRICATED BEARINGS —
Remove pressure relief
plug when greasing bearing on vertical hollow shaft drives.
Pump grease into bearing cage until it appears at the plug.
Replace pressure relief plug.
GREASE LUBRICATED SEALS —
Most gear drives and
backstops are furnished with grease purged seals which
minimize the entry of contaminants and abrasive dusts into the
drive or backstop. Gear drives and backstops are shipped with
NLGI #2 grease in the seal housing cavities unless otherwise
specified. If grease could contaminate the product, as in the
food and drug industries, it should be removed. A grease that
meets USDA “H1” classification is suitable for food
processing applications.
Periodically (at least every six months) depending upon the
frequency and degree of contamination, purge contaminated
grease from seals by slowly pumping fresh bearing grease thru
the seal,
WITH A HAND GREASE GUN,
until fresh grease flows
out along the shaft. Wipe off purged grease.
CAUTION
:
Rapid regreasing with a power grease gun can force
grease inward past the seals and plug the oil drain back system
causing seal leaks.
BACKSTOP EQUIPPED DRIVES —
Type “Y”, gear drives, use a
self contained, pawl type, backstop externally mounted on an
intermediate shaft. The backstop is furnished filled with grease
suitable for operation in an ambient temperature range of -20
°
F to
+125
°
F(-29
°
C to +52
°
C). Relubricate the backstop every 3
months (2 weeks in severe operating condition). To relubricate,
select and clean one grease fitting and pump grease into the
backstop until fresh grease appears at both seals. Refer to the
backstop manufacturer’s service manual (supplied with the drive)
for detailed maintenance instructions and recommended greases.
DO NOT use greases with molybdenum disulfide or other
EP additives.
