STORAGE - INSTALLATION RECOMMENDATIONS - LUBRICATION
LEROY-SOMER
3832 - 03.2005 / a
1 - STORAGE
Pjn servo gearboxes can be stored horizontally in a dry place
at a temperature between 0° and 30°C in their original
packaging (for a maximum of one year). (The threads and the
area below the screw heads of the locking clamps are
lubricated with molybdenum disulphide).
The service life of servo gearboxes increasingly depends on
how well they are maintained.
2 - INSTALLATION
RECOMMENDATIONS
Servo gearbox :
For the installation of Pjn servo gearbox, follow the
"Recommendations" chapter in the general manual (ref. 2557).
Servo motor :
For connection of the complete drive system (with brake),
follow the instructions of corresponding maintenance
delivered with the goods in the parcel.
3 - LUBRICATION
The Pjn servo gearbox is supplied as standard lubricated with
an oil with a viscosity of 150 mm
2
/S that is heavy pressure
wear-resistant against the risks of pitting, spalling and
abrasion with a very high natural viscosity index and complete
stability at shearing. (Klüber ref. GH6-150).
You must use an oil of the recommended type.
Please observe the oil quantities specified in the
table opposite. (Magnetic plugs make filling,
pressure relieving and draining easier, and retain any metallic
particles).
POLYGLYCOL LUBRICANTS CANNOT BE MIXED WITH
MINERAL OR SYNTHETIC LUBRICANTS OF A
DIFFERENT TYPE.
3.1 - Maintenance, draining
It is advisable to carry out initial draining after between 100
and 500 operating hours in order to remove the initial residue
from operation. Subsequent draining should preferably be
carried out every 10,000 hours. For harsh applications,
please consult Leroy-Somer. Observe the recommended
draining intervals and oil quantities.
3.2 - Plugs position
a - Servo gearboxes have an upper plug for refilling and a
lower plug for draining . The position of these plugs depends
on the operating position of the servo gearbox, which must be
specified at the time of ordering .
b - For continuous operation at rated speed, the optional
breather plug must be installed.
After installing the servo gearbox on site, insert the breather
plug in the place of one of the standard plugs and observe the
orientation of the vent hole.
3.3 - Oil capacity (cm
3
)
For all other operating positions, follow the quantities
specified in column V3.
Lubricants:
Operating position
1. Indifferent orientation
of the vent hole
2. Position of the plug for
servo gearboxes ratio 3 to
10
3. Orientation of the vent hole at the top

TECHNICAL CHARACTERISTICS - INSTRUCTIONS FOR DISMANTLING AND REBUILDING
LEROY-SOMER
3832 - 03.2005 / a
4 - TECHNICAL CHARACTERISTICS
Necessary information
a) from the servo gearbox nameplate :
1- servo gearbox model and size
2- operating position
3- fixing form : BS
4- exact reduction
5- output speed (min
-1
)
6- backlash : MEDIUM
7- serial number
8- lubrication
b) Where a servo motor is fitted to the servo gearbox,
from the servo motor nameplate :
(for the servo motor : see the corresponding manual)
- servo motor type, example : 95UMB300CACAA
5 - INSTRUCTIONS FOR
DISMANTLING AND REBUILDING
Only use appropriate tools (adequately-sized torque
wrenches, calibrated screwdrivers, etc.) or contact a
service centre (see back of servo motor manual) or
a Leroy-Somer approved centre.
Contact one of the centres to ensure the original standard of
the product is maintained.
5.1 - Dismantling
- Uncouple the servo gearbox from the machine.
- Remove the servo motor.
- Dismantle the servo gearbox.
5.2 - Rebuilding
- Proceed in the reverse order to dismantling.
- If the servo motor shaft is keyed, remove the key and check
that there is no burr on the groove.
- Degrease the servo motor shaft, the sleeve bore and the
mating surface of the flange.
- Position the 2 sleeve screws opposite the orifices used to
insert the key in the input bearing.
- If possible, assemble in a vertical position with the servo
motor above.
- Bring into contact the 2 sleeve locking screws.
- Tighten the screws of the servo motor.
- Tighten the 2 coupling screws (gradually, one after the
other, in three steps) until the recommended tightening
torque is reached (see table below).
- Slightly loosen then tighten the fixing screws of the servo
motor diagonally.
