Safety
Proper use
The couplings in the MULTI MONT SELLA series, type MMS-T...W are pluggable
claw couplings. These act in transferring torques and rotation speeds between a drive
unit and the driven machine. They reduce torsional vibrations and shock loads and
are able to compensate for misalignments.
Proper use also includes the observance of and compliance with all details contained
in these operating instructions and the related documents. This applies, in particular,
to both the safety instructions and the warning notices, and to the adherence to the
cleaning and maintenance intervals.
Any other use or any use beyond the limits of proper use is deemed improper use
and can lead to property damage or personal injury.
The following types of use, in particular, are deemed improper use:
Operating the coupling outside its operating limits, and especially at too high
rotational speeds and/or torques or continuous fatigue torques.
Operating the coupling in a substandard condition.
Having the coupling operated by inadequately trained personnel.
Operating the coupling with deactivated and/or modified protection devices.
Operating the coupling with modified add-on parts.
Improper cleaning with cleaners containing solvents, alkalis or acids.
Improper operation of the coupling results in forfeiture of the liability for material
defects and warranty.

Description
The couplings in the MULTI MONT SELLA series, type MMS-T...W are pluggable
claw couplings. These act in transferring torques and rotation speeds between a drive
unit and the driven machine. They reduce torsional vibrations and shock loads and
are able to compensate for misalignments.
The coupling consists of two coupling halves and the flexible elements. Joining the
coupling halves enables the claws with the flexible elements to interlock with each
other. This results in a practically backlash-free, positive connection, which allows for
transmission of the torque.

Description
16
Overview of type MMS-T…W (with taper bush)
The type MMS-T...W is a shaft coupling with two coupling hubs 3, 6). The coupling
hubs are each attached with a taper bush 5, 7) on the shaft of the relevant machine.
The torque is transmitted via flexible elements 4) which are guided and held in place
by a retaining cap 2). The flexible elements 4) can be mounted and removed after
loosening the bolts 1) and sliding back the retaining cap 2). The coupled machines
need not be moved for this purpose.

Description

Components
Coupling hubs
The coupling has two coupling hubs. The coupling hubs usually consist of cast iron.
They are placed on the shaft of the driven/driving machine and fixed in position by a
taper bush. The coupling hub is equipped with claws. These claws are the
counterpart to the flexible elements.
Taper bush
The taper bush is a connection element with a conical basic form and a longitudinal
slot. It acts as a form-fitting shaft-hub connection to connect the coupling hub with
the shaft of the driven/driving machine. The taper bush is tensioned into the threaded
parts by screwing in the bolts supplied. This means the conical surfaces are pressed
against each other. The coupling is held on the shaft by means of this press force.
Torque transmission occurs via the form-fitting key connection.

Description
18
Flexible elements (toothed ring, saddle elements)
The used flexible elements differ depending on the size. A split toothed ring A) is
used for sizes up to and including size 63. The individual rubber buffers are
connected to each other via an external belt. The parting line B) enables the toothed
ring to be replaced without moving the coupling halves.
From size MMS 100 on, six saddle elements 1) are used where two rubber buffers 2)
each are connected via one external belt 3).
The saddle elements are shown in the figures above and below.
The following materials are available for the flexible elements depending on the type of
application:
Natural/synthetic caoutchouc
Synthetic caoutchouc NBR)
Silicone caoutchouc VMQ)
Polyurethane PUR).

Description
19
Retaining cap
The retaining cap is slipped over the coupling hub and bolted to it. The flexible
elements are covered this way and protected against dirt and falling out. The flexible
elements can be replaced after loosening the retaining cap bolts and sliding back the
retaining cap. Depending on the size, the retaining cap is made of polyamide, sheet
steel, or cast iron.
Operating conditions
Observe the following operating conditions depending on the rubber mixture of the
flexible elements:
Rubber mixture Ambienttemperature Colour Identifier
Natural/synthetic caoutchouc in
standard design
–40 °C to +80 °C black SN
Synthetic caoutchouc NBR) –40 °C to +100 °C black SP
Silicone caoutchouc VMQ) -70 °C to +120 °C blue SX
Polyurethane PUR) -30 °C to +120 °C black UD
Contact the manufacturer in the case of deviating ambient temperatures.
For the operating conditions which are permissible for your application, refer to
the technical product description supplied with the coupling.
