Installation and maintenance of gear reducers
Please read and follow these instructions carefully to obtain
maximum performance while maintaining warranty rights on
the equipment received.
Every EURODRIVE product is factory tested and properly
packaged before it leaves our company Please report any
transport damage to the agent of the forwarding carrier.
If the reducers are to be stored before installation, the storage
area should be dry and well ventilated Prolonged storage
and/or storage in areas of high humidity, requires special
precautions. Instructions for long term storage can be obtained
from EURODRIVE If storage 15s done in an area of extreme
and rapid temperature changes, the ventilation plug should be
installed for the period of storage (See "Lubrication").
The reducers must be mounted on a firm, rigid, plane base,
preferably with a machined surface. The support must not flex
under load, and the unit has to run vibration free at all times.
Careful alignment with the driven machinery is essential In
applications that exert side loads onto the shaft, mechanical
side stops, adjustable if possible, should be installed onto the
mounting surface. To maintain the warranty, the reducer shall
not be modified or other equipment attached to it.
Installation of Driven Members
The shafts are protected against corrosion with a vinyl
strippable coating, which can be easily removed without using
chemicals If chemicals are used for shaft cleaning, avoid
contact with the shaft seals to protect seal and bearing
EURODRIVE shafts are machined with tolerances as shown
on the dimension sheets in our catalogues.
Driven members, sprockets, pulleys, and sheaves should be
heated to 80 degr C (180 degr F), and pushed over the slightly
greased shaft Metric shafts are provided with centrebores
which can be used for attachment of mounting tools.
Reducers with keyless hollow shafts (Ringfeder or Stuewe
taper-locks) require special attention See instructions on the
Never force driven members with hammer strokes onto the
shaft. Doing so will greatly decrease bearing life.
Belts, chains, etc , should be mounted as close as possible to
the casting of the reducer to reduce overhung loads on the
shaft Values for maximum permissible overhung loads are
published in EURODRIVE catalogues, or can be obtained from
EURODRIVE reducers are shipped with the proper oil level
according to the mounting position specified on the original
The reducer is provided with a red-painted level plug, a drain
plug located on its lowest
spot, and a blue-painted plug indicating the location for the
breather plug. The breather plug is shipped in a plastic bag
attached to the reducer Breather plugs for gearmotors are
shipped inside the motor terminal box. Some reducers (i.e.,
R/RF30 and S/SF30) do not require ventilation.
When the installation of the drive Is completed, the blue plug
should be located on the highest spot on the reducer The
location of the level plug and the ventilation plug must be
checked according to the mounting position data contained in
this book, pages 21 to 26.
In certain mounting positions, slight oil loss through the
breather plug--due to foaming of oil, or due to internal
agitation--might occur In these cases, the ventilation plug
can be substituted with a solid plug, since our reducers are
safe to be run sealed. For washdown applications, specially
protected ventilation plugs are available to prevent water from
being sucked into the gearcase enclosure.
Some gear reducers, specifically types R/RF30 and S/SF30,
do not need any maintenance. They can be mounted in any
position and therefore, do not have a level plug. For refills, see
page 27 for type and quantity of oil to be used.
Before starting the unit, the proper oil level has to be checked
at the red-painted level plug. If lubricant is missing, fill to the
proper level with the oil suggested on page 27 Mixing different
types of oils should be avoided Using types of oils other than
those shown on page 27 may void the warranty. Oil quantities
needed for complete refills are shown on page 28.
After the initial start up, the oil level should be checked
periodically, and the area surrounding the reducer should be
inspected for evidence of leaking oil.
We suggest changing the reducer oil every 10,000 hours of
operation, or every 2 years, whichever is shorter. With the use
of synthetic lubricants, 20,000 hours or 4 years of operation
can be obtained Adverse environments, high humidity,
aggressive media, and high temperature will shorten the useful
life of the lubricant.
CAUTION: Synthetic lubricants must not be mixed with other
types, or brands, under any circumstances.
Antifriction bearings are either lubricated by the gear oil, or are
provided with sealed grease packings EURODRIVE does not
prefer to provide field re-greasable bearings (Zerk fittings)
since todays high quality greases will likely outlast the bearing
If downtime, due to bearing failure must be avoided under any
circumstances, periodical cleaning, checking and re-greasing
with specified grease is recommended As option, the input
covers of helical gear units can be provided with regressing
facilities, or oil bath lubrication on larger units.
