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...

Complies with the current ATEX Directive for: II 2G Ex h IIC T6 ... T2 Gb X II 2D Ex h IIIC T85 °C ... 250 °C Db X I M2 Ex h Mb X Benefits N-ARPEX couplings of the ARN-6/-8/-10 series are outstanding for their application-optimized construction. The NEN, BEB, MCECM, MFEFM series meet the requirement of API 610. Couplings in accordance with API 671 are also possible. For speeds of over 1,800 rpm the five-part version with pre-assembled intermediate unit is...

Torsionally Rigid All-Steel Couplings N-ARPEX ARN-6/-8/-10 Series Introduction Design and Configurations Materials Figure 1 NEN The design of an N-ARPEX type NEN is shown in illustration, figure 1. The coupling comprises two hubs, an intermediate spacer and two plate packs that in the ARN-6 series are bolted together alternatingly with close-fitting bolts and in the ARN-8/-10 series by means of a Flender conical screw connection. The coupling is available in fixed lengths from stock. Other spacer lengths are manufactured to order. Hubs are designed with threaded pull-off holes. Hub Plate pack Intermediate...

Torsionally Rigid All-Steel Couplings N-ARPEX ARN-6/-8/-10 Series Introduction Plate-pack designs The plate packs of the N-ARPEX ARN series are designed with hexagon, octagon and decagon plates, depending on the coupling size. The number of screw connections is indicated in the denomination of the ARN-6/-8/-10 series. Hexagon plates have 6 bolting points, octagon plates have 8 bolting points and decagon plates have 10 bolting points. The hexagon plates, octagon plates and decagon plates up to size 631 are designed as ring plates. Sizes 694 to 988 are designed as segmented plates. Size 86-6 to...

Torsionally Rigid All-Steel Couplings N-ARPEX ARN-6/-8/-10 Series Introduction Permitted shaft misalignments, types NEN/NHN, BEB, MCECM/MCHCM and MFEFM/MFHFM The permitted shaft misalignments ΔKa, ΔKr and ΔKw are maximum values and must not occur at the same time. The specified axial misalignments apply to the complete coupling. The permissible angular misalignments have been specified per coupling joint. As all N-ARPEX types are designed to be doublejointed, there is a direct interrelation between radial and angular misalignment. NEN/NHN: ΔKr = (S - S1) ⋅ tan(ΔKw) BEB, MCECM/MCHCM and MFEFM/MFHFM:...
