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.
