The coupling then acts as a load-holding safety clutch until the drive is shut off by themotor control or couplingmonitoring system. ® FLUDEX couplings are hydrodynamic fluid couplings which operate on the Fottinger principle. The coupling parts on the input and output sides are not mechanically connected to each other. Output is transmitted via the oil filling which rotates in the coupling and is conducted over radially arranged blades. ® ® To compensate for shaft misalignment, the FLUDEX coupling is combined with a displacement coupling e.g. of the N-EUPEX type. Design and configurations Benefits ® FLUDEX couplings limit starting and maximum torque in the drive train and, through the property of rotational slip, serve as an aid to starting the motor, as overload protection in the event of fault and for isolating torsional vibration. ® In the case of special operating conditions, such as overload or blocking of the driven machine, the FLUDEX coupling limits the maximum torque load and prevents the inert effect of the rotatingmotor mass on the drive train. When large masses are started up, the drive train is accelerated only at the torque determined by the coupling characteristic. The starting operation is spread over time, the drivenmachine started softly and smoothly. ® ® FLUDEX couplings are used in drives for conveyor systems such as belt conveyors, bucket elevators and chain conveyors. In heavy industry FLUDEX couplings are used for applications such as blade wheel drives, crushers, roller presses, mixers, large ventilators, boiler feed pumps, large compressors, centrifuges and auxiliary drives for mills. ® The FLUDEX coupling further acts as ameans of decoupling during torsional vibration excitation. Application ® In drives with diesel engines, FLUDEX couplings are used on driven machines with a high mass moment of inertia. FLUDEX couplings are constructed of just a few, robust components. Internal components include the hollow shaft or solid shaft (106), to which the blade wheel (105) is connected. The outer housing comprises the cover (102) and the blade wheel housing (101). The joint is constructed as a bolted flange joint and sealed with an O ring. The outer housing and the shaft or hollow shaft have double bearing support and are sealed off to the outside with radial shaft seals. The coupling is provided with two filler plugs (153) with integral overflow protection and with one or two fusible safety plugs (103) in the coupling housing for protection against overheating. The fusible safety plug or a screw plug fitted in the same position also serves as a fluid drain plug and with the aid of a scale marking on the housing can be used as a level indicator. ® All FLUDEX couplings are designed with radial unset blades and are therefore suitable for rotation in both directions and reversing operation. They can be ® fitted horizontally, at an angle or vertically. In the case of FLUDEX couplings with a delay chamber it must be ensured, when fitting at an angle or vertically, that the delay chamber is below the working chamber. Further applications are, for example, pump drives, PTO generator drives, wind power systems and door and gate drives. Torsional vibration excitation with a frequency of > 5 Hz. is virtually absorbed by the coupling. 1 www.jbj.co.uk/couplings.html #DriveLineHarmony Introduction ® Fludex Fluid Couplings G_MD10_XX_00107 103 105 102 101 153 106

4 www.jbj.co.uk/couplings.html #DriveLineHarmony Introduction ® Fludex Fluid Couplings R1 R2 Cu1 Cu2 Motor Pump Turbine Pump impeller Turbine impeller Driven machine Fluid coupling G_MD10_EN_00113 Föttinger principle Two opposing, radially bladed impellers are housed in a leakproof housing. The impellers are not mechanically connected to each other. Because of the axially parallel arranged blades, the torque is transmitted independently of the direction of rotation and solely by the oil filling. Hydrodynamic couplings have the characteristic properties of fluid flow engines. The transmissible torque depends on the density and quantity of the operating fluid and increases as the square of the drive speed and the fifth power of the profile diameter denoting the coupling size. In the driven pump impeller, mechanical energy is converted into kinetic flow energy of the operating fluid. In the turbine impeller, which is connected to the output side, flow energy is converted back tomechanical energy. To generate the operating fluid circulation necessary for torque transmission, a difference in speed is necessary between the pump and turbine impellers. A centrifugal force pressure field is set up that is greater in the faster rotating pump impeller than in the turbine impeller. Depending on the FLUDEX coupling series, drive is via the inner rotor (shaft/hollow shaft with rigidly connected blade wheel) or via the bladed housing impeller (blade wheel housing). The driving impeller is the pump impeller, and the driven impeller is the turbine impeller. The difference in speed, usually termed “slip”, at the continuous operating point of the coupling is between 2 % and 6 %, depending on application and coupling size. Immediately after drive motor start-up slip is 100 %, i.e. the pump impeller is driven at the speed of the motor, but the turbine impeller remains stationary. A low-viscosity mineral oil VG 22/VG 32, which also serves to lubricate the bearings, is used as fluid. In special types water, a water emulsion or lowflammability fluidmay be used as a non-combustible fluid. The torque characteristic depends on the oil filling quantity FG in the coupling. This enables the transmissible torque on starting up to be set via the filling level. With a higher filling level the starting torque increases, while the operating slip and thus the coupling temperature rise decreases. Conversely, with a lower filling level the starting torque decreases, the coupling becomes softer, while slip and coupling temperature rise. Slip multiplied by the transmitted power represents the power loss of the coupling, which is converted into heat inside the oil filling. The amount of heat generated must be released into the environment via the coupling housing to prevent an impermissible temperature rise. The rated coupling output is mainly determined by the power loss which can be dissipated at a still acceptable operating temperature or a reasonable set slip limit. This distinguishes the FLUDEX coupling from all positively acting coupling assembly options for which the rated coupling torque is the defining characteristic.

The temperature limits of the N-EUPEX add-on coupling are shown in part 7 of this catalogue. If other displacement couplings are combined with a FLUDEX coupling, their respective temperature limits must be taken into account. For use at temperatures below -20 °C, FLUDEX couplings are generally delivered without oil filling. For use at temperatures below -15 °C, FLUDEX couplings are exclusively delivered with NBR seals (Perbunan). Balancing is a two-level balancing with the specified oil quantity or a 75%filling. FLUDEX couplings can be delivered with or without oil filling. Starting torque can be reduced without increasing continuous operating slip by using a type of coupling with a delay chamber. On these couplings part of the oil filling is initially stored inactively in the delay chamber. The starting torque is considerably reduced because of the thus reduced starting filling in the working chamber of the coupling. The filling in the delay chamber runs very slowly, mostly only at the finish of the starting operation, from the delay chamber into the working chamber, causing the active filling in it to rise gradually and the continuous operating slip to reach a value corresponding to the whole filling. Technical Specifications Balancing FLUDEX couplings In deviation from the balancing specifications in Chapter E, all FLUDEX couplings complying with DIN ISO 21940 are balanced to balancing quality G6.3 for 1800 rpm. For operating speeds higher than 1800 rpmmicro-balancing, based on operating speed, can be requested. FLUDEX couplings are balanced in accordance with the half parallel key standard. Other balancing standards must be specified in the order. Add-on couplings are subject to the standards as set out in Chapter E.

Introduction ® Fludex Fluid Couplings Depending on the series selected, different starting characteristics arise during starting. If special requirements, based on the operating method of the prime mover or driven machine, are made of the coupling or the coupling is to be used in extreme environmental conditions, please give specific details in the enquiry or order. The form “Technical specifications for the selection of type and size” on page 13 can be used for this purpose. Start-up characteristics during the starting process The coupling with fusible safety plugs with identity marking T3 is suitable for the operating conditions set out in the ATEXDirective 2014/34/EU: Equipment group I (below-ground applications) of categoryM2 If used in potentially explosive environments under ground, aluminum couplings must be provided with a robust enclosure to preclude the risk of ignition caused by e.g. friction, impact or friction sparks. The deposit of heavy-metal oxides (rust) on the coupling housingmust be prevented by the enclosure or other Operating conditions for FLUDEX couplings in potentially explosive atmospheres Equipment group II (above-ground applications) Temperature class T3 of categories 2 and 3 for environments where there are potentially explosive gas, vapours, mist and air mixtures and for environments where dust can formpotentially explosive atmospheres. suitablemeans. FLUDEX couplings can be delivered with fitted brake disk or V-belt pulley. Designing the belt drive or the brake disk to conform with the guidelines is the responsibility of the subassembly supplier. It should be noted that there is a risk from, amongst other things, electrostatic charges and hot surfaces. Under BGR 132 (regulations of German Institute for Occupational Safety) the use of V-belts in conjunction with IIC gases is not permitted. Axial retention Weights specified in the dimension order tables apply tomaximumbore diameters without oil filling. Axial retention is provided by a set screw or end washer with a retaining screw for shaft ends to DIN 748/1 long with a centering thread to DIN 332/2. Selection of FLUDEX coupling In accordance with the requirements catalogue various series, sizes and types of FLUDEX coupling are available. The FLUDEX coupling series is characterized by various flow chamber configurations, fitted delay chambers or fittings in the flow chamber. The types are determined by the design of the add-on coupling. This results in different starting factors and characteristics which can be used for the most varied applications. The size is specified by stating the flow outside diameter. When selecting, the series required for the application, taking into account the starting factor and the characteristic, must be selected. Bore and keyway width tolerances are specified in: Selection of FLUDEX series FLUDEX couplings, which are to be used solely as an aid to starting the motor under no special conditions, can be selected according to the assignment tables from page 14 page 18 (for n = 1500min-1) or from (for n = 3000min-1).

This enables the advantages of the compensating chamber and the working chamber to be used to best effect. Combinations with brake drums/disks and pulleys can also be easily achieved. When the coupling is started, part of the oil filling in the area of greatest slip is forced into the radially inner chambers and the compensating chamber by the strong rotational flow. This causes the effective oil filling in the working chamber to be reduced and the desired torque limitation (approx. twice TN) to be achieved during starting. By means of additional fittings the coupling torque at the start of the starting operation can be limited to approx.1.5 times the rated value. During run-up to speed the compensating chamber again empties into the working chamber, and this helps to reduce slip. FGand FV series – drive via the housing When the coupling is started up, part of the oil filling is forced into the damming chamber. This enables the desired torque limitation (approx. twice TN) to be achieved during motor starting. In the FV series the delay chamber also receives part of the oil filling in accordance with the fluid level when the coupling is stationary. During starting the effective oil filling in the working chamber is reduced by the amount of fluid in the delay chamber, thus considerably From the delay chamber located on the drive side, the oil is fed back time-dependently to the working chamber via small holes and the coupling torque is raised, even if the output is blocked. FLUDEX FG and FV series couplings are designed for drive via the coupling housing. In the FV series (coupling with delay chamber), the motor drives the coupling housing, comprising a blade wheel (101) and a cover (102), via the flexible N-EUPEX coupling (part 2/3) and the delay chamber (115). The rotational flow of the coupling filling drives the blade wheel (105) and the hollow shaft (106) on the output side, which is mounted on the gear unit or drivenmachine shaft. In the FG series (basic coupling), there is no delay chamber, and the flexible coupling is directly flange-mounted on the blade wheel. FG series couplings are used for normal starting torque limitation, as a starting clutch for isolating vibration and for overload limitation in the event of drive blockage. reducing the starting torque (approx. 1.5 times TN). The property of the coupling with delay chamber can be used advantageously, for example, to soft-start empty, partly loaded and fully loaded conveyor belts. This replenishing function enables a drive to be soft started with a very low starting torque and with an almost load-free motor. At the same time, however, increased load torques can be overcome by the torque increase in the coupling.

The delay chamber is designed as a hub carrier (120) and is mounted on the motor shaft. The hub carrier is flange-fitted to the housing (101, 102) of the FLUDEX coupling. Output is via the blade wheel (105) and the shaft (106) to the flexible N-EUPEX coupling connecting to the gear unit or drivenmachine. With types FND, FNDB and FNDS the coupling can be dismounted radially without The normally stronger motor shaft bears the weight of the hub carrier (cast version) and the main coupling. The gear unit shaft carries only the brake drum or disk and the output-side part of the flexible coupling. At the same time, the principle of the drive-side delay chamber with the capacity for increasing torque time-dependently is retained. FN couplings have the same fields of application as FV couplings. However, they offer special advantages in the brake disk design because of the weight distribution. moving the coupledmachines. Because of the larger delay chamber, FN couplings enable even softer starting than FV couplings. Torque limitation during motor starting is approx. 1.3 times TN.Afurther advantage of types FNDB and FNDS is the favorable weight distribution. 8 www.jbj.co.uk/couplings.html #DriveLineHarmony
