These operating instructions contain information about the
transport, assembly, commissioning and service of , gear
units/geared motors from STOBER.
Observe the applicable documents of attached motors and
additional drive components.
1 Operation in accordance with its in-
tended use
Gear units/geared motors from STOBER comply with the val-
id standards and regulations. They are intended for installa-
tion in commercial machines and systems. Intended use
includes:
• Use of the gear unit/geared motor exclusively for the ap-
plication that it was designed for.
• No modifications to the gear unit/geared motor by the
customer.
• No overload of the gear unit/geared motor with regard to
the maximum permitted speeds, torques and tempera-
tures that are specified in the order confirmation.
• Compliance with the inspection and maintenance inter-
vals.
• Observance of this documentation.
If the gear units/geared motors are to be used to left or hold
loads, the machine manufacturer must check whether addi-
tional safety measures are required.
1.1 Surface temperature
To ensure safe operation of the gear unit, the surface tem-
perature of the gear unit must not exceed the following tem-
perature values:
• For mineral lubricants 80° C,
• For synthetic lubricants 90° C.
For this reason, observe the following:
• The standard version of gear units/geared motors from
STOBER may be used at surrounding temperatures be-
tween 0 °C and +40 °C. Different surround temperature
ranges are specified in the order confirmation for special
versions.
• The gear units must be protected from overload and be
adequately ventilated. More detailed information can be
found in the Assembly chapter.
2 Safety information
CAUTION!
Burns!
The surface temperature of the gear unit can significantly ex-
ceed 65° C in operation!
Allow the gear unit to cool down sufficiently before touch-
ing it or wear protective gloves.
Also follow the applicable national, local and system-specific
requirements.
2.1 Personnel requirements
All work on the electrical equipment of the drive units must be
performed by qualified electricians. Installation, maintenance
and repairs of mechanical parts must be performed by fitters,
industrial mechanics or persons with comparable qualifica-
tions.
3 Technical data
The technical data of the gear unit/geared motor can be found
in the order confirmation. This refers to the lubricant used that
is specified on the nameplate of the gear unit. Other technical
data as well as dimensional drawings can be found in the ap-
propriate catalog from STOBER.
4 Transportation and storage
When transporting the gear units/geared motors make certain
not to damage the shafts and bearings with impacts.
Use the ring screws on the gear unit housing for vertical trans-
port of the gear units. Sling the gear units without ring screw
with a suitable support cable directly on the gear unit housing.
Note that ring screws are only intended for vertical transport
of the gear units without additional attachments. In addition
sling the motor mounted on the gear unit and make sure that
there is no diagonal pull.
If the ring screws are removed after assembly, permanently
seal the threaded holes according to the protection class of
the gear unit.
The gear units/geared motors may only be stored in en-
closed, dry rooms. Storage in open air areas with a roof is only
permitted for brief periods. Protect the gear units/geared mo-
tors from all damaging environmental effects and mechanical
damage.
Avoid extreme temperature fluctuations with high relative hu-
midity when the gear units/geared motors are being stored
temporarily to prevent formation of water from condensation.
Long-term storage
If long-term storage is planned, protect the bare parts of the
gear unit against corrosion. Completely fill the variable speed
drive with integrated spur gear stage with lubricant that is
specified on the nameplate. Reduce the lubricant to the cor-
rect filling quantity according to the nameplate before com-
missioning the drive.

5 Mounting
Inspect the delivery for any transport damage immediately af-
ter you receive it. Notify the transport company of any dam-
age immediately. Do not operate damaged gear units/geared
motors.
Remove the packaging of the gear unit/geared motor and dis-
pose of it according to the applicable legal requirements on
site.
NOTICE
The lip seals of the shaft seal rings can be damaged by
the use of solvents.
When removing the corrosion protection, make sure that
the lip seals of the shaft seal rings do not come into con-
tact with solvents.
Completely remove all corrosion protection on the shaft ends
prior to installation.
5.1 Installation positions
The version of the gear unit and the lubricant amount filled at
the factory is matched to the installation position of the gear
unit. The gear unit may therefore only be installed at the in-
stallation position specified in the order confirmation. A sign
on the gear units shows which gear unit side must point down-
wards.
5.2 Installation of gear unit
Mount the gear unit on an even, vibration-reducing and tor-
sion resistant substructure. Use screws of strength class 10.9
to fasten the gear unit via the pitch circle diameter. Use
screws of strength class 8.8 for all other fastening types.
Observe the following for assembly:
• The housing feet and attachment area may not be braced
against each other.
• The permitted shear and axial forces may not be exceed-
ed.
• Screws for filling and draining the lubricant as well as
available ventilation valves must be freely accessible.
• Earthing the gear unit housing via metal components of
the system must be ensured.
Gear units/geared motor with solid shaft; installation of
power transmission elements:
The output shaft is equipped with a centering thread accord-
ing to DIN 332, Sheet 2, which is provided both for fitting and
for axial mounting of transmission elements (gear, chain
wheel, pulley, coupling hub) by means of a central screw.
Shaft ends with a diameter up to 55 have tolerance ISO k6,
those larger than 55 have tolerance ISO m6. The fitting keys
correspond to DIN 6885, Sheet 1.
NOTICE
Damage to the bearing race.
Avoid all impacts to the output shafts.
5.3 Ventilation
The gear units are closed on all sides and are not vented.
6 Commissioning
Check the following before commissioning:
• Is it ensured that the gear unit is adequately vented and
no external heat input (e.g. Via a coupling) is present?
The cooling air may not exceed a temperature of 40° C.
• Does the attached motor cover the full flange surface of
the motor adapter for gear units with motor adapters?
• If ring screws were dismantled, are the holes sealed with
appropriate plugs?
• Is it ensured that no gear unit overload relating to the per-
mitted torque can occur due to the mounted motor? (The
permitted torque can be found in the order confirmation.)
WARNING!
Risk of injury due to moving parts!
Before switching on the drive, check the following:
Are no persons in danger due to start-up?
Is all protection and safety equipment properly installed,
in test operation too?
Is the drive not blocked?
Are the brakes released?
Is the direction of rotation of the drive correct?
Are components attached to the output such as feather
keys or coupling elements adequately secured against
centrifugal forces?
7 Service
7.1 Inspection and maintenance
The gear units are provided with life-long lubrication. The
specification and filling quantity of the lubricant is given on the
nameplate of the gear unit.
To ensure problem-free operation, check the shaft seal rings
for leaks every 3000 operating hours or every 6 months at the
latest.
Maintenance of the adjustment mechanism
If the speed of the variable speed drive is frequently adjusted
or the variable speed drive is operated in wet areas, lubricate
the gear rack guide of the motor valve every month. Also ap-
ply grease over both lubrication nipples using a grease gun.
Now pass through the entire adjustment range several times.
7.2 In the event of disruptions
7.2.1 General faults
Changes compared to normal operation indicate that the
function of the drive has been impaired. This includes:
• Higher power consumption, temperatures or vibrations
• Unusual noises or odors
• Leaks on the gear unit
• Monitoring devices responding
In this case, stop the drive as quickly as possible and contact
STOBER Service.

7.2.2 Friction system faults
The following faults of the friction system can occur when op-
erating the variable speed drive.
For variable speed drives, if the output shaft does not turn al-
though the motor is running or the specified torque is not
transferred, or if (existing) blockage monitoring responds, the
following may be the causes:
• The wear limit of the race is exceeded. In this case, re-
place the race.
• The running surfaces of the friction system oily. Rectify
the cause of the oiling, clean the friction system and re-
place the race.
After a brief blockage of the output shaft, knocking sounds are
audible because a calotte has formed on the race surface.
Small calottes can recede. Replace the race for persistent
knocking sounds.
The replacement of the race is described in the document
with ID 441262.
If the speed of the gear unit adjusts automatically, retighten
the brake screw at the adjustment handwheel.
