Turbo Coupling with Constant Fill
Voith Turbo Coupling with Constant Fill
1 Voith Turbo Coupling with
Constant Fill
1.1 Function
Fig. 1
The Voith turbo coupling is a hydrodynamic coupling working to the Föttinger principle.
Its main elements consist of two blade wheels - the pump impeller and the turbine
wheel - enclosed by a shell. Both wheels are provided with bearings relative to each
other. The power is transmitted with hardly any wear, there is no mechanical contact
between the power-transmitting parts. A constant amount of operating fluid is in the
coupling.
The mechanical energy provided by the drive motor is converted into kinetic energy of
the operating fluid in the connected pump impeller. In the turbine wheel, this kinetic
energy is reconverted into mechanical energy.

Blade wheels

Turbo Coupling with Constant Fill
Voith Turbo Coupling with Constant Fill
Three conditions are to be considered with regard to the coupling function:
Fig. 2
Standstill
The whole operating fluid rests in the
coupling.
Fig. 3
Starting condition
The pump impeller accelerates the
operating fluid with increasing motor
speed causing a circulating flow in the
worki
ng chamber. The whole blade
space of the turbine wheel is flooded,
and the turbine wheel starts to move as a
result of the kinetic energy of the fluid
flow. The coupling characteristic curve
determines the torque curve during start-
up.
Fig. 4
Nominal operation
During nominal operation, only the torque
required by the driven machine is
transmitted. The low speed difference
between pump impeller and turbine wheel
(the so-
called rated slip) results in a
stationary flow condition in the coupling.

Turbo Coupling with Constant Fill
Declarations of Manufacturer
4 Declarations of Manufacturer
4.1 Declaration regarding assemblies and components
Since 29 December 2009, a new Machinery Directive 2006/42/EC has to be applied
bindingly in the member states of the European Community.
Voith turbo couplings of Product Group "Start-up Components", as defined by the new
Machinery Directive 2006/42/EC and the explanations of the guidelines published in
December 2009 to implement the Machinery Directive, are neither "machines" nor
"incomplete machinery", but rather assemblies or components.
As our products are no incomplete machinery, we do not issue a declaration of incor-
poration as per Machinery Directive 2006/42/EC.
An EC Declaration of Conformity must not be issued for these products either, nor CE
marking be provided, unless specified by other EC directives or regulations.
Voith as certified company ensures that the basic safety and health requirements for
their products are always be met by internal quality management systems and by
applying harmonized standards.
The technical documentation for Voith products is so comprehensive that they may be
installed reliably into machinery or incomplete machinery. Safe operation of the
complete machinery with regard to Voith products is also ensured at a later date when
observing this documentation.

Turbo Coupling with Constant Fill
User Information
5 User Information
This manual will support you in using the turbo coupling with connecting coupling in a
safe, proper and economical way.
If you observe the information contained in this manual, you will
– increase the reliability and lifetime of the turbo coupling and installation,
– avoid any risks
– reduce repairs and downtimes
This manual must
– always to be available at the machine jobsite
– be read and used by every person who transports the turbo coupling, works on
the turbo coupling or commissions the same.
The turbo coupling has been manufactured according to the latest design standard
and approved safety regulations. Nevertheless, the user's or third party's life may be
endangered or the machine or other property impaired in case of improper handling or
unintended use.
Spare parts:
Spare parts must comply with the requirements determined by Voith. This is
guaranteed when original spare parts are used.
Installation and/or use of non-original spare parts may negatively change the
mechanical properties of the Voith turbo coupling and thus have an adverse impact
on safety.
Voith is not liable for any damages resulting from the use of non-original spare parts.
Use only appropriate workshop equipment for maintenance. Professional
maintenance and/or repair can only be guaranteed by the manufacturer or an
authorized specialist workshop.
