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 g 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.

Maintenance
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.
