Safety
Proper use
The highly flexible Reich TOK coupling has been specially designed for applications
requiring extremely low torsional stiffness. Furthermore, it is particularly well suited to the
compensation of axial and radial displacements of resiliently mounted drives. The wide
range of flexible coupling elements and adaptive designs provides standard solutions for a
wide variety of different tasks. These can be complemented by specific customised
designs on request. The flexible element is designed to combine high torque transmission
capacity and high displacement capacity with high speed capability. Its stiffness can be
adapted to requirements by selecting different rubber qualities. The adaptive designs are
based on the standard flywheel adapter dimensions according to SAE J 620.
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 protective guards.
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.

Duties of the owner
The owner of the coupling is bound by laws and regulations to issue instructions which
ensure safe operation.
The owner must define a “responsible person”. Only this person is authorised to issue
a work clearance permit for working on and with the coupling. Work on the coupling
described herein must not be executed unless the written work clearance permit for
the execution of that work is available from the responsible person.
The owner of the coupling must ensure that only qualified and authorised personnel
performs the following activities on and with the coupling:
−Transportation
−Storage
−Assembly
−Putting into operation
−Operating
−Decommissioning
−Cleaning
−Servicing
−Disposal.
Persons whose ability to react is affected, for example, by the use of alcohol,
medicines, drugs, etc., must not work on or with the coupling.
The owner of the coupling must regularly train the personnel working on the coupling
in the following areas:
−Use of the personal protective equipment
−Safe working practices
−Applicable accident prevention regulations
−Hazards arising from the coupling whilst in operation
−Behaviour in an emergency
−First aid measures.
The owner must ensure that the applicable country-specific laws and guidelines
including the health protection regulations, the occupational health and safety
regulations and the fire prevention regulations, are adhered to.
The owner must ensure that personnel receiving training, hands-on training, briefings
or making an apprenticeship exclusively works on and with the coupling under the
constant supervision of an experienced specialist.
The operator must ensure that the coupling is enclosed by an adequately dimensioned
separating protective guard which can withstand a coupling rupturing. It must allow
sufficient ventilation of the coupling; see page 72.
Before commissioning the coupling, the owner or a person authorised by the owner
must ensure that the following requirements are met:
−Proper use of the coupling must be ensured.
−All protection devices must be properly mounted and functional.
−All safety regulations must be adhered to.

Wear ear protectors in areas in which your hearing may be damaged.
Wear a respiratory protector during work when your respiratory system may be
damaged.
Make sure that the work areas and escape routes are not blocked at the place of use.
The owner must issue instructions for the wearing of personal protective equipment in
accordance with the risks existing at the place of use.
Note regarding residual dangers
The coupling has been constructed according to the state-of-the-art and the recognised
safety rules and relevant standards. Wherever possible, sources of danger have been
eliminated in the design or ruled out through suitable devices. Residual dangers may
nevertheless arise when using the coupling.
Dangers to persons or impairment of the coupling and other property can especially occur
if the coupling:
is improperly transported, mounted, commissioned and maintained by non-qualified
or untrained personnel,
is operated improperly,
is not used properly,
is not serviced properly,
is not cleaned properly,
is not decommissioned properly,
is not stored properly.
Basic safety instructions
Danger to life due to rupturing of the coupling
A damaged or improperly mounted coupling can rupture during operation. Parts flying
around can cause life-threatening injuries.
The coupling must be mounted exclusively by specialist personnel qualified for this
task.
The coupling must be operated exclusively in flawless condition.
The maintenance intervals must be adhered to.
The owner must mount a protection device which is capable of withstanding rupturing
of the coupling.

Safety
13
Danger to life due to improper transportation and handling of the coupling
If the coupling or its components are inadequately supported during transport, assembly
or disassembly, there is a risk of crushing injuries in the event of the coupling or its
components falling down.
Exclusively use undamaged lifting and lashing gear which is suitable for the load.
Secure the coupling and its components during transport, assembly or disassembly to
prevent them from falling down.
Do not stand under suspended loads.
Wear the personal protective equipment specified by the owner.
Avoiding risks of injury due to entanglement
Perform all work required on the coupling only when the coupling is stationary.
Switch off the prime mover prior to all work on the coupling.
Secure the prime mover to prevent reactivation.
Exclusively operate the coupling with a mounted and functional protective guard.
Affix a label warning of the hazard of entanglement on the protective guard.
Avoiding risks of burns from hot surfaces
The surface of the coupling can become hot during operation.
Do not touch hot surfaces.
Allow the coupling to cool to hand temperature prior to maintenance work.
If necessary, check the surface temperature with an infrared thermometer.
Wear the personal protective equipment specified by the owner.
Avoiding risks of poisoning
There is a risk of poisoning when working with solvents or preservatives.
Wear the personal protective equipment specified by the owner.
Observe and follow the instructions contained in the safety data sheet for the solvent
or preservative being used.
Make sure that the workplace is adequately ventilated.

Description
The couplings in the TOK series, types TOK…F2, TOK…D F2, TOK…F2K, TOK…D F2K,
TOK…TK, TOK…D TK, TOK…R F2K and TOK R TK are used to transmit torques and speeds
between a drive unit and the driven machine in horizontal position. They reduce torsional
vibrations and shock loads and are able to compensate for displacements.
Depending on the type, they consist of the flange, the coupling hub, the actual flexible
coupling element, adapter flange and an optionally supplied spacer ring. After assembly, a
torsionally flexible connection is established between the drive unit and the driven
machine.
Overview of type TOK...F2
With this type, two different mounting lengths can be achieved depending on the
configuration of the coupling element.
