3.4 Weights
The weight of the drive is shown on the rating plate of the gear unit or the gear motor, if higher than 30 kg;
it can always be found in the shipment documents.

When there are several rating plates on one drive, the value on the main gear unit is decisive.

The weight given refers to the delivery condition of the product ex FLENDER TÜBINGEN.
3.5 Sound power level

The A-qualified sound power levels LWA of a selection of gear units in Figure 3.5 were determined
according to DIN EN 21680 measured with testing apparatus to DIN IEC 651.

The sound is dependent upon speed, power rating and ratio.

The MOTOX-N-drives mostly lie within the dark range. Gear units with very small ratios, high power
rating and high input speed may lie in the hatched range.

If no proper measuring system can be established when measuring again at the place of use, the
measurement on the FLENDER TÜBINGEN test rigs are valid.

4. Handling, Incoming goods and Storage
4.1 Handling
The drive is shipped in assembled state. Ancillary equippment (such as for example pipes and valves)
are shipped packed separately.
The packing of the gear unit will differ, dependent on the method of shipment and size. The packing,
unless otherwise agreed contractually, complies with HPE Packing Guidelines.
The symbols shown on the packing should be noted. Their significance is as follows:

This side up Fragile Keep dry Protect Centre of gravity Use no Sling here
Goods from heat hooks

When handling and loading and unloading of the drive, excercise special care
Attention! to avoid damage due to the use of force.

The drive should be lifted by the largest eye bolt present, this is usually the eye
bolt on the gear.
Check fixture of the eye bolt, tighten if necessary.
Eye bolts on the motor may only be used for
- handling of the motor alone or
- as an additional support for reaching a horizontal mounting position of the
drive.

The permissible attaching weight is to be observed:

M M8 M 10 M 12 M 16 M 20 M 24 M 30
m [kg] 140 230 340 700 1200 1800 3600
Highest load exercised by the drive to be attached in kg with tension ↑ in the direction
M of the screw axis.

Use additional suitable lifting devices (ropes or similar) for transport or

Attention! installation in order not to exceed the max. load in the direction of the eye bolt
axis.
When attaching with several chains and ropes, two ropes must already be
sufficient to support the complete load. Lifting devices such as ropes and
similar should be secured against slipping.

The threads in the shaft ends must not be used for attaching eye bolts for
Attention! handling.

Transport fixtures, if present, should be removed and stored or be made

Attention! noneffective according to additional notes.
For further transport reuse or make effective again.

4.2 Incoming goods

The contents of the shipment are listed in the shipping documents. The shipment should be checked
for completeness and shipping damage immediately on receipt. If necessary, a loss advice should be
written out in the presence of the forewarder, otherwise repairing the damage without costs will not be
possible.

Damaged drives must not be put into operation.

BA G298 EN 08.98 Page 11 of 39

4.3 Storage
The drives should be stored in dry rooms with minimum temperature fluctuations in their positions of
use on a horizontal wooden support and covered.

The storage area must be free of vibrations (shocks) as otherwise the

Attention! anti-friction bearings may be damaged.

It is not permissible to stack drives on top of one another.

The gear units are provided with internal preservation, the free shaft ends and the flange surfaces are
provided with a protective coating.
Note: Unless agreed to the contrary by contract, a warranty period of 6 months is given for
the standard preservation. The warranty period starts to run on the date of delivery
of the gear unit.
In the case of prolonged interim storage (> 6 months) check preservation and renew it, if necessary
(see Section 7. “Startup”).
The contractually agreed external coating (type, structure, colour) was carefully applied by spray
painting. See 5.11 for the resistances of the coating.
Note: Do not damage the coating!
Mechanical (scratches), chemical (acids, alkaline solutions) or thermal (sparks,
welding beam, heat) damage leads to corrosion and to the failure of the external
protection.

If stored in the open, the drive should be covered with special care and it
Attention! should be ensured that neither moisture nor foreign matter are allowed to
collect on the gear unit.

5. Technical description

5.1 General description

The gear units are supplied as two- or three-stage helical gear units. The gear units are suitable for the
different mounting positions taking into consideration the oil level.

5.2 Housings

The gear unit grey cast iron housings are stable, vibration dampening and are designed for continuous
operation.

The housings are manufactured using totally novel processes on most modern machines. This results
in a high centre distance precision, which avoids a punctual overload of the tooth flanks. Furthermore,
the high precision guarantees a favourable bearing load as well as good noise characterisitcs.

5.3 Toothed components

The toothed gear unit components are hardened and ground. The high quality of the tooth system as
well as the flank- and profile-corrected involute gearing minimizes the noise level of the gear unit and
at the same time optimizes the carrying capacity of the flanks.

5.4 Lubrication

The components of the tooth system are adequately supplied with lubricant by splash lubrication. This
ensures that the gear units are especially maintenance-free.

Attention! See Section 10. “Maintenance and repair” for trouble-free operation.

5.5 Bearings

All shafts are mounted in anti-friction bearings. Lubrication of the anti-friction bearings is effected by
splash lubrication assisted by the gear wheels. Bearings which are not supplied with lubricant hereby
are enclosed and grease lubricated (lifetime lubrication).

5.6 Shaft seals

Radial shaft seal rings at the shaft outlet prevent lubricant from escaping from the housing and dirt
entering the housing. In case of higher ambient temperatures (60°C-100°C), shaft seal rings from
temperature resistant material are used.

5.7 Cooling

The gear units do not require any additional cooling. The generously dimensioned housing surface is
sufficient for dissipating the heat loss in case of free convection.

The surface of the gear unit or the gear motor should be kept free of dirt
Attention! (see Section 10. “Maintenance and repair“).

5.8 Couplings

As a rule, flexible couplings should be provided for the input drive and output drive sides of the gear
unit.

If rigid couplings or other input drive and output drive elements are used which give rise to additional
radial and/or axial forces (for example gear wheels, belt pulleys, etc.), this must be agreed on by
contract.

Couplings with peripheral speeds at the outside diameter up to 30 m/s must

Attention! be statically balanced. Couplings with peripheral speeds above 30 m/s require
dynamic balancing.

The special Operating Instructions should be noted for operation of the couplings.

BA G298 EN 08.98 Page 13 of 39

5.9 Backstop
The gearboxes can be provided with a mechanical backstop for certain requirements. During operation,
this permits rotation in the specified direction only. This direction is marked by a corresponding direction
of rotation arrow.

The backstop incorporates centrifugally operated grippers. When the gear unit is rotating in the
specified direction, the inner ring and the cage with the grippers rotate, the outer ring remaining
stationary. From a certain speed of rotation, the grippers lift off and the back stop now operates without
wear.
The backstops are lubricated ready for duty, they don’t need to be serviced.

To prevent damage to or destruction of the backstop, it is essential to ensure

Attention! that the motor is not run against the locked backstop.
Please observe the notes on the gear.
5.10 Rating plates
The rating plates of the gear units or gear motors are generally made from laminated aluminium foil.
They are covered with a special transparent label, which guarantees an excellent long term resistance
against sunlight and media of all kinds (oil, grease, sea-water, cleaning solvents, etc.).
The adhesives and materials are chosen in such a manner, that an extremely tight fixation and a durable
good readability is given, even at the limits of the operating temperature range (–40°C ... +155°C).
The edges of the rating plates are included under the respective painting, see 5.11 “Coats of paint”.

In special cases, i.e. with special specifications, riveted or screwed metal rating plates are used.

6. Installation
6.1 General information on installation
During installation, the safety notes in Section 2. “Safety notes” should be observed.
Installation should be carried out by specialist personnel with extreme care. Damage caused by
improper execution results in the exclusion of our liability.
Right at the planning stage, it should be ensured that there is adequate space around the gear unit for
installation and subsequent care and maintenance.
Adequate space for air intake should be left for drives with fan.
The drives may overheat if positioned in strong direct sunlight. Provide
Attention! appropriate protective devices such as cover, roof or similar!

Before commencing installation, adequate hoist equipment must be provided for lifting the drives.
No welding work must be carried out on the drive. The drives must not be used
Attention! as ground points for welding work. Components of the tooth system and
bearings may be destroyed by welding.

Note: Use shoulder studs of property class 8.8 or higher for mounting the drives.

All mounting possibilities assigned to the respective mounting position

Attention! should be used.

6.2 Drives with foot mounting

6.2.1 Foundation

The foundation must be flat.

Note: The flatness of the gear unit support must not exceed the following values:
for gear units up to size 88 ≤ 0.1 mm
for gear units above to size 108 ≤ 0.2 mm

It should be executed in such a way that no resonance vibrations occur and no vibration can be
transmitted from adjacent foundations. Steel structures on which the gear unit is installed must be
torsionally rigid. They are to be designed corresponding to weight and torque, taking into account the
forces acting on the gear unit.
When mounting the gear unit on a concrete foundation, using foundation blocks, suitable recesses
should be provided in the foundation.
When alignment has been completed, slide rails should be grouted to the concrete foundation.
6.2.2 Installation of gear units with foot mounting

When making use of the highest possible output torque or shearing forces besides the foot mountings
by studs or bolts of property class 8.8. suitable additional positive connections such as e.g. cylindrical
grooved pins, dowel pins, spring type straight pins or fitting pipes should be provided. These measures
are also necessary for dynamically loaded screw connections.
In some cases headed screws can’t be used, due to lack of space for insertion. If in doubt, please
contact us giving the type of gear.
Do not use spring rings, serrated lock washers, spring washers or tooth lock
Attention! washers, plate springs or idler pulleys as substitute for the above mentioned
positive connections.

The gear unit housings must not be distorted when tightening the fastening
Attention! screws.

Note: See 10.2.5 for tightening torques.

Note: Gear units which require the use of a hoist due to their weight should be attached
according to 4.1.

BA G298 EN 08.98 Page 17 of 39

6.3 Drives with housing flange mounting
With housing flange (C-Type) at size DZ/ZZ108-168, the customer side can be pinned.
The output flanges are designed in a manner, that the permissible torques and radial loads can be
transmitted safely by the screw connection.
When there is need for additional safety, e.g. reversing or operation with heavy
Attention! shock load, the existing pin holes can be used.
The gearbox can also be bored and pinned together with the maschine. In this
case the given dimensions should be observed.

DZ/ZZ108 DZ/ZZ128

DZ/ZZ148 DZ/ZZ168

With heavy straight pins to DIN 1481: Use existing pinholes in the housing flange.
With dowel pins to DIN EN 28740 / ISO 8740: Bore the mating part together with the housing.

Attention! Do not exceed max. bore depth given (A-A).

6.4 Drives with foot-/flange mounting

(Mounting positions B3/B5, V1/V5, V3/V6)
Fastening of the drive unit for transmission of forces and torque only must be effected by flange
mounting or foot mounting according 6.2 to avoid distortion of the gear unit housings.
Second fastening facility (foot or flange) normally is provided for attached elements, e.g. guard covers
or similar, while its weight should not exceed max. 30% of the drive unit weight.

The gear housings must not be distorted through the attached elements.
Attention! Likewise, no forces, torque and vibrations should be transmitted to the drive
units, e.g. when small auxiliary units are attached.

10.2 Description of maintenance and repairs
10.2.1 Carrying out oil changes

When changing the oil the gear unit should always be filled with the oil grade
Attention! previously in use. Mixing oils of different grades is not permissible. In
particular, synthetic oils may not be mixed with mineral oils or different
synthetic oils. When changing over from mineral oil to synthetic oil or from
synthetic oil with a particular base to synthetic oil with another base, the gear
unit must be flushed through thoroughly with the new oil grade.
When changing the oil, the housing must also be cleaned thoroughly by flushing with oil to remove oil
sludge, abraded particles and residues of old oil. For this purpose, the same oil grade should be used
as is in use for operation of the gear unit. Viscous oils should be warmed beforehand. Only when all
residues have been removed, the fresh oil may be poured in.
Note: The oil should be drained off after shutdown, while the gear unit is still warm.
S Shut down the gear unit by shutting off the drive unit.

10.3 Lubricants
Oil selection should always be determined by the oil viscosity (ISO VG class) specified on the rating
plate of the gear unit. The viscosity class is valid for the operating conditions agreed on by contract.
Under different operating conditions, it will be necessary to consult us at FLENDER TÜBINGEN.
We have compiled a Lubricant Table of the lubricants suitable for the gear unit (see Table 10.3).
We are acquainted with the composition of these lubricants and know that, in accordance with the latest
technology, they possess values in respect of loadability, corrosion protection, load carrying capacity
with micro-pitting, as well as compatibility with seals and internal coating on which the design of the gear
unit has been based.
Thus, we recommend that our customers should select a lubricant from this Table, taking in account
the viscosity class stated on the rating plate.
The lubricants listed have no approval according to USDA -H1/-H2 (United
States Department of Agriculture) and are as such not, or only limited
approved, for use in the food or pharmaceutical industry.
The lubricants are not, or only limited biologically decomposeable. They are
usually according to the Classes 2 or 1 of hazard for water.
If lubricants are necessary according to these classifications, please contact
the factory.
If the gearboxes are filled with special lubricants from the factory for the cases
given above, this can be seen on the name plate e.g.: CLP-H1 VG220 or
CLP E VG220.

Note: As a precaution against misunderstandings, we would like to point out that the
recommendation does not imply any release in the sense of a warranty for the quality
of the lubricant provided by your supplier. Each lubricant manufacturer must warrant
the quality of his product himself.
If for any reason you deem important, you do not follow our recommendation, you yourself will assume
the responsibility for the technical suitability of the lubricant.
In order to assist you to minimize the technical risk in such cases, we recommend that you consult us
at FLENDER TÜBINGEN.
S In the case of synthetic oils not listed in Table 10.3, the corrosiveness of the oil to our internal coating
should also be checked. A check of this nature is carried out by us at cost (cost on request).

11. Spare parts stock, service addresses

11.1 Stocking spare parts

Maintaining a stock of the most essential replacement and wearing parts on site will ensure that the
drive is serviceable at all times.
We assume warranty only for original spare parts supplied by us.

We would like to explicitly draw attention to the fact that spare parts and
Attention! accessories not supplied by us have not been tested and approved by us
either. Fitting and/or use of such products can therefore under certain
circumstances adversely effect structurally specified properties of the drive
and will thus impair active and/or passive safety. No form of reliability or
warranty will be assumed by FLENDER TÜBINGEN GmbH for damage caused
by the use of non-original spare parts and accessories.

Please note that special production and supply specifications frequently exist for components and we
will always offer spare parts in accordance with the latest technology and the latest legal requirements.

When ordering spare parts, the following data should be stated:

Order No. (see rating plate 3 )

Type designation (see rating plate 4 )

Part No. (three-digit pos. No. from the spare parts list, or six-digit ident. No. or
seven-digit part No.)
