2. Technical data / intended purpose
2.1. Intended Use
Hydraulically actuated clutches are characterised by a low spatial require-
ment, low moment of inertia and very reliable number of switching cycles.
With sufficient internal oiling of the plates they are largely maintenance-
free.
Furthermore, their design as a multiple-disk clutch enables the transfer
of higher torques and with the appropriate internal oiling a large heat
load is permissible. The frictional heat arising during switching processes
is absorbed by the plates and then is conducted away from the clutch
through the internal oiling.
The closing and filling time between the switch signal and the complete
closure of the clutch is dependent on the piston stroke, piston surface and
the volumetric flow of oil available from the pressure oil supply.
2.2. Appropriate use
Our products are intended exclusively for use in accordance with the tech-
nical data stipulated per the design shown on the product drawing
(0 . . . - . . . - . . - . . . . . .)
The order-specific design which was performed by Ortlinghaus may only
be used for the intended application.
The technical data specified by the customer is a component of the
intended use. Insofar as a specification sheet which has been approved by
both sides is present, it is also essential. The customer is responsible for
the correctness of its data.
Our product is intended to be integrated into a system or machine or to be
assembled with other components to form a system or machine. For this
reason, the product should only be brought into circulation once the system
or machine into which the product is to be integrated has completely
fulfilled the applicable EU machinery directive.
Intended use also includes complying with the directions given in this oper-
ating manual, and paying attention to any residual dangers. Remaining
hazards are described in the hazard warning sections of the following
chapters. During the various applications (operating stages) in which
damage to the machine or hazards to personnel can arise, the operator
must ensure that appropriate safety measures are applied. Observe the
applicable national regulations pertaining to accident prevention and envi-
ronmental protection.

Ortlinghaus-Werke GmbH Operating instructions TPI 1570 EN
09.2011 7
2.3. Improper use
Any alternative or additional use other than that described in chapter
“Intended use” and “Appropriate use” is considered to be improper use.
Ortlinghaus is not liable for damages arising from this.
Especially, but not exclusively, improper use of our product includes:
➜is used as a bearing in the sense of supporting and guiding moving
machine parts with respect to the stationary part
➜is used outside without sufficient protection against environmental
conditions
➜is overloaded by an excessive speed or excessive torque when the
clutch is engaged
➜is overloaded by excessively long sliding actions on the friction surfaces
(e.g. by overloading)
➜is operated with insufficient cooling or with an operating pressure that is
too low
➜is loaded by an excessively high switching frequency e.g. in activation
mode
➜is operated with an incorrect fluid medium with wet running system
NOTE!
➜If the safety instructions and residual hazards are not observed then this
is also considered improper use.
WARNING!
• Unauthorised conversions and modifications on the product are not
permitted for reasons of safety.
➜Modifications to or on our products are prohibited. Where this is not
observed, any claims made against Ortlinghaus-Werke GmbH will be
deemed void.

2.4. Functional description
CAUTION!
• The rated operating pressure is:
Table 2: operating pressure
Built dimensions 66 - 80
Rated operating pressure [bar] 25 bar
Max. perm. pressure* 37,5 bar
* Occasional pressure peaks up to 37.5 bar do not cause damage to the
clutch. This pressure is only permissible during pressure testing.
➜Never operate the brake at a higher pressure. This can cause screws
to shear.
CAUTION!
• An axial force is exerted on the piston as a result of the centrifugal force
of the residual oil in the piston chamber when internal parts of the clutch
are rotating.
• If the axial force is greater than the counter-pressure of the pressure
springs then the clutch no longer opens completely but rather the clutch
engages itself independently.
➜Never operate the clutch at a speed higher than the permitted
maximum speed. Please refer to the certificate drawing for this.
CAUTION!
➜The installation of the pressure oil supply must be configured such that
the pressure oil can flow out of the piston chamber back though the
control valve to the pressure oil unit tank, without any counter-pressure.
2.4.1. Engage
The pressure oil moves the piston (2.1) against the force of the pressure
springs (2.4, 2.5). In this process the plate pack, comprising the outer
plates (8) and inner plates (9), is pushed against the stop plate (6) and is
axially compressed. The clutch is now engaged and transfers the torque
caused by the actuation pressure between the input side and the output
side.
2.4.2. Disengage
When the actuation pressure is released, the piston (2.1) is pushed back to
the home position by the springs (2.4, 2.5, 2.6). At this stage, the pressure
oil must be able to flow freely from the two piston chambers. The piston
space is formed by cylinders (1.2) and pistons (2.1).

4. Installation and assembly instructions
The supplier or operator is responsible for the installation of the product
described. Comply with the applicable regulations and requirements as
well as these OI. Check the operational readiness before installation. Use
appropriate lifting gear for handling whilst the installation work is being
carried out.
Follow the instructions for installation.
WARNING!
• Observe the hazard notes in chapter “Maintenance” and “Repair, modifi-
cation”!
➜Observe the applicable environmental regulations.
It is necessary to carry out a check for compliance with the geometric
tolerances after installation. It may be necessary to correct radial and axial
misalignments by adjusting the shaft(s) and other machine parts. Note that
there may be thermal expansion, shaft bending and soft mountings/bear-
ings. Check tightening torques of all bolts and correct if necessary.
WARNING!
• Please obtain the values required for the check from the product drawing
or contact Ortlinghaus-Werke.
➜Personal injury or machinery damage are potential effects of non-obser-
vance and are caused, for example, by components breaking or heat
generated by contact with moving parts.
➜If the geometrical installation conditions are not observed, our product
must not be installed.
4.1. Installation conditions
• Moving parts must be safeguarded by the customer against unintended
contact, without significantly compromising the ventilation.
• The installation area, with its connection faces, and the product must be
free of grease, dust or other contamination.
• It must be ensured that the friction components are not contaminated by
operating fluids such as oil or grease (other than the specified operating
fluids) during installation or subsequent operation. Exceptions are the
lubricants approved for operation. If clamping rings are used for shaft
connection then no oil must emerge from these after installation.
• There must be no damage present at the joints of the machine.
• Observe the fitting and position tolerances and the data on the product
drawing. Otherwise small cracks or gaps from angular or radial misalign-
ment of the shaft/machine are created.
• Ensure that there is adequate space available in the installation area.

Ortlinghaus-Werke GmbH Operating instructions TPI 1570 EN
09.2011 13
4.2. Installation
• First check the position of the parallel key or rather the position of the
toothed profile, oil inlet holes and cooling oil holes on the shaft. (One or
more radial grooves are provided in the hub hole for the cooling oil.)
• Push the clutch unit without housing onto the shaft and lock the clutch
unit in the correct position for the oil inlet.
CAUTION!
• The fit selection must not lead to an impermissibly large expansion of the
clutch's inner drive.
➜For example, a fit of H6/m6 is the max. permissible.
• Now slide the housing carefully over the clutch unit, without damaging
the plate toothing, up to the centring seat on the corresponding machine
component.
• Screw and pin the housing and machine component to one another.
CAUTION!
➜Secure all screw connections against loosening independently, e.g. with
Loctite type 262 and observe the prescribed tightening torques.
CAUTION!
➜If it should be necessary, due to existing conditions, to connect the
housing with the machine component first and then to slide the clutch
unit onto the shaft and into the housing simultaneously then particular
care must be taken to avoid damaging the plates.

5. Commissioning
Prior to commissioning, the connection on the drive side and output side
must be checked for correct attachment and a functional test carried out.
Furthermore, a functional test must also be carried out after maintenance
or repair with a stationary system or machine.
With hydraulic systems, the existing contamination must be filtered out
before first use. The piston chamber should be bled via the connection
provided (if available) prior to commissioning.
Check for unusual noises, vibrations and oscillations. Monitor the oper-
ating temperature. If unusual heating should be detected in the first hours
of operation, the commissioning is to be halted.

6.2. Emergency switching unit
The clutches from this series are equipped with an integrated emergency
stop device as standard.
Caution! In the event of the hydraulic system failing press the plate
stack against the piston with the aid of the emergency engagement
screws. The emergency engagement screws should be loaded equally
when doing this.
Only operate the clutch by means of the emergency stop device if there is
an emergency, i.e. if the pressure oil supply of the clutch can no longer be
assured. Under no circumstances may the emergency stop device be used
during continuous operation.
The emergency stop device is actuated when the drive shaft and driven
shaft are stationary. The requisite tightening torques for the emergency
engagement screws can be found on the clutch drawing. After emergency
switching the plates must be checked for damage, and in the event of there
being damage or if the wear limits are exceeded, they must be replaced.
6.2.1. Operation of the emergency stop device
• If the hydraulics breakdown, tighten the emergency engagement screws
(15) on the cylinder with the torque specified on the product drawing.
• The piston (2.1) compresses the plate pack.
• The clutch is now engaged and transfers the torque caused by the pres-
sure between the input side and the output side.

6.3. Recommended oils
The function of the selected lubricant is of decisive importance for the
permanent operation of our wet-running products.
➜Please refer to factory norm
ON 9.2.10 for a list of the oils which we recommend.
➜The factory standard can be requested from us easily by telephone or
email (for telephone number or email address, see front page).
The indicated oil recommendations are based exclusively on the function
of the product described here.
Restrictions may be caused by other components connected to the
same oil circuit.
Please note the system manufacturer’s approved oils list.
CAUTION!
• Under no circumstances should lubricants of different types be mixed
together! Mixing them together can negatively alter the properties.
➜This can lead to functional impairments, e.g. reduction in friction or foam
generation. Damage to the product or machinery, e.g. seals/gaskets, is
also possible.
