2Safety instructions
The entire manual, especially the safety instructions, must be considered by every person working with the
planetary gearbox. In addition, all legal regulations, in particular regarding accident prevention and environmental
protection, must be followed.
2.1 Machinery Directive
According to the EU Directive 2006/42/EG, planetary gearbox units are machine components. It is therefore
neither a machine nor an incomplete machine, but rather components for installation in machines and systems.
The planetary gearbox units are not subject to the Machinery Directive. A CE marking and a conformity guideline
according to the Directive 2006/42/EG are not permitted for the planetary gearboxes.
The commissioning of the planetary gearbox is not permitted within the scope of the Machinery Directive until it
has been established that the machines and systems in which the planetary gearbox is going to be installed comply
with the provisions of Directive 2006/42/EG.
2.2 Intended use
The planetary gearboxes are designed for converting rotational speed and torque in electrical machines, systems
and components intended for industrial and commercial use. The gearboxes are designed to be mounted to
electric motors.
When installing the gearbox unit in electrical machines and systems, commissioning is only permitted once it is
clearly established that all local laws and guidelines are being followed.
Improper use of the planetary gearbox can lead to serious personal and property damage. The gearboxes may only
be used within their technical performance data. Exceeding the technical data can lead to immediate or creeping
damage to the planetary gearbox. Any exceeding of the technical data is not permitted; this is considered
improper use.
2.3 General safety information
Warning!
Incorrect assembly and utilization, improper use and inadequate
maintenance can lead to serious property damage and severe injuries
or even death.
▪All following safety instructions must be observed.
▪The use of the planetary gearboxes is only permitted according to
the intended use and by consideration of the technical data.
Warning!
Rotating components of the planetary gearboxes can sling away. This
can lead to severe damage and injuries or even death.
▪All tools and assembly aids must be removed before
commissioning the planetary gearboxes.
▪Keys and other components on the shafts that are detachably
connected must be removed or covered before starting if they are
not secured by the attachment.

parts. This can lead to severe injuries or even death.
▪Before starting up and during the entire operation, a sufficient
distance must be maintained to all rotating gearbox parts and
attachments.
▪Assembly and maintenance work may only be carried out when
the planetary gearbox is at standstill and when appropriate safety
precautions have been met, for example securing the entire
system against starting up or unintentional movement.
Notice
Leaking operating fluids and lubricants and improper disposal can
cause environmental damage.
▪Leakages must be prevented during handling, storing, operation,
maintenance and disposal.
▪The planetary gearboxes must be disposed of properly.

3.2 Lubrication
Grease: Tribol GR100-0PD Manufacturer: Castrol
Under normal operating conditions, the grease used serves as permanent lubrication based on 15.000 operating
hours or 3 years. If the temperature is above 90°C during continuous operation or if there are very large
temperature fluctuations due to extreme operating cycles, the lubricant change is required after 10.000 operating
hours.
In the event of damaging the shaft sealing rings, resulting in a loss of grease, a factory repair and inspection is
necessary.
3.3 Operating temperature
The operating temperature of the standard gearbox is in the range from -25°C to +90°C. Operating temperatures
above or below the specified range are only permitted with special precautions. Please contact us in these cases.
3.4 Technical data
The technical data of the respective planetary gearboxes can be found in the current product catalog, the technical
datasheet or our website: www.eisele-getriebe.de
4Delivery and handling
4.1 Delivery condition
The planetary gearboxes are packed in safe and appropriate packaging. Transport damage must be reported to the
shipping company immediately upon receiving the delivery. All packaging materials must be disposed of at the
designated disposal points, the country-specific requirements must be met.
The complete scope of delivery of the planetary gearboxes is noted on the enclosed delivery note. The planetary
gearboxes are to be checked for completeness immediately after receiving the delivery. Please contact us directly
in case of missing or incorrectly delivered parts.
4.2 Transport
The planetary gearboxes do not contain any transport devices. Transport the planetary gearboxes preferably in the
delivered packaging in order to avoid possible transport damage. During the entire transport, it must be ensured
that the permissible storage temperature (see chapter 4.3) is not exceeded and that the packaging is protected
from moisture.
Please note: The planetary gearboxes can be damaged by improper transport, e.g. by putting them down too hard.
Attention!
When transporting and handling the planetary gearboxes, there is a
risk of crushing due to their weight.
▪Only suitable means of transport and lifting gear may be used for
transport.
▪Suitable safety equipment, for example, safety shoes and safety
gloves, must be worn.
4.3 Storage
The planetary gearboxes should be stored in the original packaging or in a horizontal position in a dust-free and
dry environment and in a temperature range between -10°C and +40°C. Storing outdoors is not permitted. The
planetary gearboxes can be stored for up to 2 years if these storage conditions are kept.

5Assembly and Installation
The gearing tolerances of low backlash planetary gearboxes must be very precise and require a very exact
installation of the motor pinion in the planetary gearbox, in order to guarantee good operating noises, operating
efficiency and prevent potential wear. Therefore, the concentricity of the motor shaft, the coaxiality and the axial
runout of the mounting flange of the drive motor must comply with DIN 42955-R.
5.1 Motor assembly
a) Check motor flange and motor shaft regarding compliance with tolerances according to DIN 42955-R.
b) Remove eventual damages (dents, ridges)
c) Check the gearbox motor flange for damage and remove eventual damage.
d) Carefully slide the planetary gearbox onto the motor while applying slight pressure.
e) Tighten the screw of the clamping hub coupling with the specified torque.
f) Tighten the connecting screws between the motor and the planetary gearbox crosswise.
If the motor flange does not comply with DIN 42955-R, increased operating noises and wear can be expected,
which will reduce the life time of the gearbox. The values in the technical data can then no longer be regarded as
binding.
A detailed description of the motor assembly is provided in the respective assembly instructions. These are
available on the internet at www.eisele-getriebe.de
5.2 Attaching couplings, toothed pulleys, etc.
Couplings, pulleys, gear wheels, sprocket wheels etc. are to be mounted up onto cleaned or lightly greased shafts
with the help of the axial threaded hole in the gearbox output shaft or by heating. Pressing or knocking on can
cause bearing damage and must be avoided.
5.3 Installation
The planetary gearboxes are sealed on all sides and can be installed in any mounting position.
The mounting seats (centering) and contact surfaces must be undamaged and clean. The shafts which are to be
connected must be in exact positional accuracy to the contact surfaces in order to prevent damaging loads due to
misalignment for bearings, shafts and housing in the overall system.
6Commissioning and operation
6.1 Precautions before commissioning
Before commissioning the planetary gearboxes, the following requirements must be met.
▪All safety instructions must be taken care of.
▪Assembly and installation must have been carried out in accordance with the descriptions above.
6.2 Operating temperature
When operating the planetary gearboxes, the surface heats up.
Attention!
Planetary gearboxes heat up during operation, through which all
surfaces heat up. Touching the planetary gearboxes can cause burns.
▪All accessible areas of the planetary gearboxes must be secured by
fixtures or warning signs.
▪Before touching the planetary gearbox, e.g. for work on the drive,
one must wait until the surface has cooled down.

Overheating of the planetary gearbox can damage the lubricant and the seals in particular. During commissioning,
check that the surface temperature does not exceed the maximum permissible temperature after several hours of
operation. The operating temperature is given in the technical data (see chapter Fehler! Verweisquelle konnte
nicht gefunden werden.).
6.3 Sound emission
The sound emission of the planetary gearbox varies depending on the size, design and installation situation. The
maximum running noise can be found in the technical data (see chapter Fehler! Verweisquelle konnte nicht
gefunden werden.). It should be considered that the noise emission of the entire drive, meaning the motor +
planetary gearbox + add-on parts, is significantly influenced by the damping behavior of the entire system.
Increased running noise can be caused by an incorrect installation of the planetary gearbox. If the specified
maximum running noise is exceeded, the installation of the planetary gearbox must be checked, otherwise there is
a possibility of damaging the planetary gearbox or the entire system.
7Maintenance
Sliding and rolling friction cause a certain amount of abrasion on certain gearbox components such as bearings,
shaft seals and toothing over the course of the operational time. This abrasion is reduced to a minimum through
the use of the lubricant and therefore extends the service life of the planetary gearbox components.
The selection of the gearbox size depends on the transmission power and the bearing load. If the gearbox is
selected correctly, the load on the gear teeth is within the fatigue strength range of the gear material. Pitting or
fatigue failure in the toothing are therefore excluded.
7.1 Maintenance intervals
The planetary gearboxes have a lifetme lubrication. The planetary gearboxes are maintenance-free under
appropriate operating conditions within the technical specifications. If the gearbox is selected correctly, the service
life of the gearbox bearings corresponds to the expected service life of the machine. The elements relevant for
testing are limited to the gearbox grease and the shaft sealing rings.
The service life of the shaft seal used depends on various factors such as rotational speed, temperature, grease
quality and environmental conditions. After 10.000 operating hours, we recommend regularly carrying out visual
inspections of the planetary gearbox every 5.000 operating hours. If leakage is detected on the drive or the output,
a replacement is required at short notice.
7.2 Grease change
As described in chapter 3.2, under normal operating conditions, a grease change is required after 15.000 operating
hours or after 3 years. In order to change the gearbox grease, the planetary gearbox must be dismantled. We,
therefore, advise having Eisele Antriebstechnik carry out the grease change.
7.3 Recommissioning after testing or maintenance
The outside of the planetary gearbox must be cleaned prior to recommissioning. All safety precautions required for
testing and maintenance are to be removed. Chapter 6 must be paid attention to in order to ensure safe
recommissioning.
