7.2 Lubrication
The gearboxes are supplied without oil.
Before use, the gearbox must be fi lled with oil up to the level indicated using one of the lubricating oils advised.
The choice and the quantity of oil will be referred to the installer/user based upon the type of application.
7.3 Paint
The supplied gearboxes are not painted. A few parts are treated with a base layer of water soluble epoxy ester red
oxide. It is the responsibility of the customer to carry out the surface treatment using a paint that is compatible
with the base layer. O-rings must be protected during the painting.
7.4 Installation of fl ange motors
The installation of the motors to the coupling fl ange supplied by Jahns is a particularly simple operation, but it
must be carried out following the following important suggestions:
-Lubricate the coupling with a light fi lm of grease or anti-seizure lubricant;
-Ensure that the motor rests freely on the gearbox fi xing fl ange without forcing on either the shaft or the spigot;
-Tighten screws.
For further information refer to the maintenance and operation manual.
7.5 Installation of motors with connection couplings
When a connection coupling between motor and gearbox is used, one must verify that the alignment between
the motor and the gearbox is compatible with the type of coupling. Couplings are widely used in industrial
applications for the various functions that they can perform such as:
- limit the input torque,
- dampen vibrations coming from the motor,
- compensate small misalignments.
For the application of couplings, reference must be made to the component’s supplier operating manual.
7.6 Weights
For the gearboxes aproximative weights see page G.241.
8. Storage
The gearboxes must not be stored in the open or in direct contact with the ground. For long time periods they just
be stored full of oil, with the external worked parts covered with grease and the coupling surfaces protected with
anti-oxidant agents and operated under vacuum (a complete rotation of the output shaft is suffi cient) at least once
every two months.
For further information regarding storage, please refer to the maintenance and operating manual.
