BA 2010
Operating Instructions, 02/2018, A5E38093846A/RS-AC 13
Technical description
2
2.1
General description
The gearbox is supplied with one, two or three transmission stages.
The gearbox is suitable for various mounting positions. Observe the correct oil level.
Housing
The housings for sizes 18 and 28 are made of die-cast aluminum. The housings for
sizes 38 to 208 are made of cast iron.
Geared components
The geared components of the gearboxes are hardened. In the case of helical worm
gearboxes the worm is hardened and ground, and the gear is manufactured from bronze.
The bevel gear stage of the bevel helical gearbox is lapped in pairs.
Lubrication
The geared components are supplied with adequate lubricant by means of dip lubrication.
Shaft bearings
All shafts are mounted in roller bearings. The roller bearings are lubricated by means of dip
lubrication or oil spray lubrication. Bearings that are not supplied with lubricant are closed
and grease-lubricated.
2.2
Shaft seals
The radial shaft sealing ring, combination shaft sealing ring, labyrinth seal, and slide ring
seal at the shaft outlet prevent lubricant from escaping from the housing and impurities from
entering it.
Radial shaft sealing ring
At higher ambient temperatures over +40 °C to +80 °C, shaft sealing rings made from
temperature-resistant material are used, subject to contractual agreement.
The radial shaft sealing ring is used as the standard type of seal. It is provided with an
additional dust lip to protect against contaminants from outside.

Technical description
2.3 Cooling
BA 2010
14 Operating Instructions, 02/2018, A5E38093846A/RS-AC
Combination shaft sealing ring (optional)
The combination shaft sealing ring offers an improved oil seal, for example, additional
sealing lips prevent the ingress of dirt. The separate sealing system prevents shaft shrinkage
due to corrosion or dirt. The grease packing prevents the sealing lips from running dry.
When carrying out repairs, e.g. if the shaft has shrunk, you can replace the standard seal
with a combination shaft sealing ring.
2.3
Cooling
NOTICE
Dust deposits prevent heat radiation
Dust deposits prevent heat radiation and cause a high housing temperature.
Keep the gearbox free from dirt, dust, etc.
The gearbox does not normally require additional cooling. The generously dimensioned
housing surface is sufficient for dissipating heat losses where there is free convection. If the
housing temperature exceeds a value of +80 °C, please contact Technical Support.
2.4
Backstop
ATEX version gearboxes
The drive speed in the table "Drive speed when using backstops" must be reached
in continuous operation.
Starting and stopping operations ≤ 20 starts / stops per hour are permissible.
NOTICE
Replacing the backstop
Drive speeds below 1 000 rpm or frequent starting and stopping operations
(≥ 20 starts / stops per hour) will limit service life.
Do not use the same backstop for prolonged periods; replace backstops regularly.

Technical description
2.4 Backstop
BA 2010
Operating Instructions, 02/2018, A5E38093846A/RS-AC 15
NOTICE
Damaged or destroyed backstop
Do not run the motor against the backstop.
Note the directional arrow on the gearbox.
The gearbox can be fitted with a mechanical backstop. The backstop can be fitted either in
the coupling lantern or in the 2nd stage of the bevel helical gearbox. It permits only the
correct direction of rotation during operation. This is indicated by an arrow pointing in the
corresponding direction.
The backstop is fitted with centrifugally operated sprags. When the gearbox is running in the
specified direction, the inner ring and the cage with the sprags also rotate while the outer
ring remains stationary.
Where the backstop is used in the coupling lantern, lifting of the sprags is ensured when the
drive speed is above the speed listed in the table. The backstop is wear-free. It does not
require maintenance.

When used in the bevel helical gearbox (gearbox intermediate shaft), the backstop operates
at speeds below the lift-off speed of the sprags in a separate oil chamber. The oil must be
changed at the same intervals as the gearbox.

Technical description
2.5 Rating plate
BA 2010
16 Operating Instructions, 02/2018, A5E38093846A/RS-AC
2.5
Rating plate
The rating plate on the gearbox or geared motor is of coated aluminum foil. It is covered with
a special masking film which ensures permanent resistance to UV radiation and media of all
kinds, such as oils, greases, salt water and cleaning agents.
The adhesive and the material ensure firm adhesion and long-term legibility within the
operating temperature range from -40 °C to +155 °C.
The edges of the rating plate are paint-finished to match the color of the gearbox or motor to
which it is affixed.
In special cases, riveted or bolted metal plates are used.
2.6
Surface treatment
2.6.1
General information on surface treatment
All paint finishes are sprayed on.
ATEX version gearboxes
The gearbox is delivered complete with primer and paint finish.
If the gearbox is delivered with primer only or unpainted, a paint finish must be
applied which meets the applicable guidelines for the specific application. The
primer does not provide adequate corrosion protection.
ATEX version gearboxes
When applying conductive paint, the operator must ensure that the paint remains
in a perfect state.
The paint finish must be checked at intervals of approximately 2 - 3 years.
ATEX version gearboxes
An excessively high electrostatic charge must be avoided.
Ensure that highly active mechanisms that cause the paint finish to generate a
charge are avoided.
Highly active mechanisms that can generate charges:
•
Fast air with high dust content directed past the gearbox
•
Sudden escape of compressed gases that contain particles
•
Harsh abrasive processes (this does not mean manual cleaning / wiping with
cleaning cloths)

Technical description
2.6 Surface treatment
BA 2010
Operating Instructions, 02/2018, A5E38093846A/RS-AC 17
WARNING
Danger due to electrostatic discharge
For paint finishes in explosion group III, the paint can be electrostatically charged as a
result of intensive dust turbulence or processes with high levels of electrostatic charging.
Risk of explosion as a result of processes with high levels of electrostatic charging
Minimize the risk of electrostatic charging by applying effective measures according to
IEC 60079-32-1.
NOTICE
