Warning!
Always work with gloves to
protect yourself from burns
from hot coupling parts!
Even warming of the shaft
hub at 80 °C to 120 °C is
harmless in order to simplify
assembly.
Recycling/disposal
Used grease must be disposed

The coupling is generally delivered assembled. The coupling
must be disassembled and checked for completeness prior
to assembly.
The gear hub must be clamped at the marked areas for
drilling.
If the customer carries out the hub bore then the hub must
be aligned carefully with the outer diameter in order to
adhere to the required concentricity
The maximum values for the drilling diameter Ø dmax must
be adhered to in all events.
The hubs must be secured against axial displacement on
the shaft ends using an adjusting screw, shaft locking plate
or suitable oversize element.
Attention: The adjusting screw should never be under
the O-ring in the casing.

The maximum permitted displacements must always be taken into account!
The valid data can be found in the following table (Table 1).
Attention: the coupling may never be adjusted ‘to zero’!
A small offset is necessary in order to achieve lubrication of the gearing.
Heat expansion that is to be expected during operation must be taken into account
when adjusting the cold system, so that the maximum permitted displacement values
are not exceeded during operation.
Displacement values are maximum values that may not occur simultaneously.
The values must be reduced if there is simultaneous radial and angular displacement.

An angular displacement of Kw= 0.1° is necessary at all times in order to guarantee lubrication of the gearing.

Only use fitting screws and nuts in the condition as delivered. The fastening elements may
not be cleaned or additionally lubricated.
Secure the fitting screws against twisting and tighten the nuts with the given torque.
Any adjusting screws must be secured against unwanted loosening and flying off during
tightening using a suitable adhesive such as e.g.: Loctite 222.

Place the filling openings horizontally.
Open the screw plug on the opposite side before filling.
Fill lubricant into each half of a coupling, for example
using a grease press, until it comes out of the opposite drill
hole.
Select a suitable lubricating grease from Table 5.
Conventional roller bearing grease is not suitable for use
in Gear Couplings.

Maintenance
The torsionally stiff Gear Coupling RINGFEDER®TNZ must be
maintained and lubricated regularly!
Please check the following points during
routine maintenance work on the system:
Lubricant quantity in the coupling
Leak tightness of the coupling
Adjustment of the coupling
A tight fit on all fastening elements
Remove dust and dirt deposits on the coupling parts
Inspection and maintenance
The coupling must be re-lubricated after every 1,000 hours of
operation.
After every 5,000 hours of operation or at least once every two
years the grease must be changed, gears and seals inspected
for damage and the adjustment checked.
The position of the gear hub and the sprocket sleeve to one
another must be marked before opening the coupling.
Place the geared parts back together in their original position
after the inspection. The same gears must always interlock as
before.
It is recommended to exchange the seal elements as well as the
screws and nuts as part of the maintenance.
General information on operation
Please note the identification data when using the coup-
ling (see product Product Paper & Tech Paper ”Gear Cou-
plings“). They may never be exceeded without the written
authorisation of RINGFEDER POWER TRANSMISSION.
In order to ensure the failure-free, long-term operation of
the coupling it must be adjusted in accordance with the
design specification in the Product Paper & Tech Paper ”Gear
Couplings“ with an operating factor that is suitable for the
operating conditions. Any modification to the conditions
of use or the operating parameters necessitates an inspec-
tion of the coupling configuration.
At the start and during operation please pay attention to:
changes in running sounds,
vibrations,
leaks,
other unusual occurrences.
Attention!
If you discover irregularities at the start or during operation
then please switch the drive off immediately!
Determine the cause of the fault and resolve it.
All the machine components and operating circumstances
must be taken into account when searching for the fault.
Coupling operating temperature:
-10 °C to +80 °C
