Flender Mechanical Power Transmission Couplings available from jbj Techniques FLUDEX couplings are hydrodynamic fluid couplings which operate on the Fottinger principle. 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. To compensate for shaft misalignment, the FLUDEX® coupling is combined with a displacement coupling e.g. of the N-EUPEX® type. Railway Couplings Couplings for rail vehicles developed, tested...

JBJ has a wealth of experience in established and niche applications, such examples are: Mechanical drives for subsea wave energy, steel works crucible handling equipment or marine winch drives. We are happy to have them on our side for our UK coupling customers, especially for the supply of the recently optimized...

Fludex® Fluid Couplings Benefits 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. 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. When large masses are...

Fludex® Fluid Couplings Materials • Blade wheel and housing: Cast aluminum AlSi10Mg or AlSi9Mg. • Shaft and hollow shaft: Steel with a yield point higher than 400 N/mm2. • Static seals and radial shaft seals: Perbunan NBR or Viton FPM. • Add-on parts: Grey cast iron EN-GJL-250, spheroidal graphite cast iron EN-GJS-400 or steel. Fusible safety plugs If a FLUDEX coupling is operated with an impermissibly high slip for a prolonged period, the oil filling and the coupling housing will overheat. Fusible safety plugs which release the oil filling into the environment upon reaching a preset temperature...

Fludex® Fluid Couplings Coupling Size Perm. speed in rpm Radius of travel R in mm From coupling size 297, the thermal switching equipment can be used up to a peripheral speed of 50 m/s. At higher speeds, an EOC system should be provided. Motor contactor Limit switches Snap-action switching contact Wiring proposition EOC System On the EOC system the temperature-dependent magnitude of the magnetic field of the EOC transmitter is measured and used for a switching pulse. The transmitter signal is transmitted via the fixed sensor to the evaluation instrument and there compared with the set value. If...

Fludex® Fluid Couplings Function Föttinger principle Pump impeller Fluid coupling machine Pump 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...

Fludex® Fluid Couplings Continuous operation Operation of the delay chamber 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...
