ON THE MOVE FOR 36 YEARS Flender ZBG for high-speed and underground trains – we use the world’s best coupling to make track changes simple. FLENDER COUPLINGS RAIL COUPLINGS Gear couplings from the Flender ZBG series make the best possible contribution to safeguarding the maximum availability of your rail vehicle – whether it is an underground train or a high speed train. Comprehensive test runs involving continuous operation and interpolated empirical values indicate a 99.9% chance of a 36 year service life. A life spent travelling Millions of kilometres of track, icy Siberian temperatures, extreme heat, maximum starting torques and revolution speeds, extremely dusty conditions, axial or radial jolts at high speeds – whatever route you use it on, the grease lubricated Flender ZBG is always in its element. First-class service at a standard price We help you to reduce costs as the long maintenance intervals of Flender ZBG gear couplings keep their life cycle costs to a minimum. The components are maintenance-free for up to three million kilometres of travel or a running time of up to 12 years. We also get your vehicle back on the rails quicker as the main Flender ZBG inspection can be combined with checks on both the motor and the gear unit; these no longer have to be inspected separately. Thanks to the integrated grease nipple, relubrication takes less than two minutes. More than 50,000 couplings supplied; more than 1,8 Mio years of cumulative operating time: we have tested and monitored the Flender ZBG gear coupling over many years of use. Not once have we found a technical fault with the gear pairings. Even with high mileage and an average of eight to ten years without a grease change, the low-wear Flender ZBGonly has aminimal amount of surface burnishing. Endurance testing Outstanding performance at maximumcapacity When using gear couplings on high-speed trains, physical load limits are far from rare. Following years of use in real-life conditions, we can confirm that the Flender ZBG gear couplings offer an outstanding performance and the utmost in safety. The approach journeys, switch cross-ings and highspeed journeys simulated within the scope of performance tests have shown that this particular coupling has clear load reserves. Axial jolts are absorbed by damping end stops; radial jolts are compensated for by the constant gap between hinge points. This means there can be no contact between metal components within the coupling. The Flender ZBG coupling is also weight-optimized. Heavy parts are directly attached to the motor or gear unit shafts; the coupling’s inner components compensate for any operational misalignments. The patented slip hub protects the drive system. Shortcircuit torques of the motor are restricted with a tolerance of +/– 15%. Sealed grease chambers also prevent the lubricant from escaping. The potential fire risk that exists with conventional couplings is therefore eliminated. 4 www.jbj.co.uk/couplings.html#flender
Impressive in extreme conditions The availability of your rail vehicle must remain as high as possible throughout the year. The Flender ZBG functions equally perfectly over a huge temperature range of +60°C to -60°C. The Flender ZBG itself runs at a low temperature, even at the maximum star t ing torque, wi th major misalignments and at high speeds. In extremely dusty conditions, you can completely rely on the optimized seal system. 5 www.jbj.co.uk/couplings.html#flender ADVANTAGES OF THE FLENDER ZBG checks. » Service life of up to 36 years. » Wear-resistant and service-friendly with very long maintenance intervals. » Main inspection combined with gear unit and motor » On request, initial lubricant filling can occur on delivery. » Simple and rapid lubrication using the grease nipple. » Good emergency running properties thanks to sealed grease reservoirs. » Clear load reserves, even after extremely long » Reliable running if the chassis is icy and at running times. temperatures well below zero. penetrating. » Optimized seal system to prevent dust from » Heat-resistant, even in extreme conditions.
YOUR 24/7 TRAVEL CARD Valid for years in any country around the world: the available quality of the Flender rail coupling series GKG, LBK and MBG forlocomotives, streetcars and many other rail vehicles. FLENDER COUPLINGS RAIL COUPLINGS Flender LBK connecting rod couplings have radially arranged rubber elements, which make it possible to radially replace the elastic elements beneath the vehicle. The connecting rod couplings have a split spacer and can be ultra-compactly connected to the gear unit. They are driven using selfcentring cyclo-palloid gear teeth in the “axle connection” version and flanged to the drive wheel in the “wheel connection” version. They are used for low-floor streetcars. Flender connecting rod couplings from the LBK series. The connecting rod coupling LBK 330 and themembrane couplingMBG 200 have been successfully used with Cityrunner streetcars. 6 www.jbj.co.uk/couplings.html#flender
Flender rail couplings create reliable connections for locomotives and streetcars. With state-of-the-art technology and high-precision workmanship, they have been successfully used in thousands of vehicles around the world. Our standard range contains solutions for most drive train tasks; customized products are also available in specific cases. Flender cardan couplings from theGKGseries. Flender GKG cardan couplings are elastic, double-jointed output couplings used to compensate for primary suspension misalignments in the bogie with full torque trans-mission between the gear unit and the powered wheel set shaft. The coupling parts can be individually installed on the gear unit and wheel set shaft. By screwing the brackets onto the spherical bearing pins, the coupling can be installed simply using standard tools. The spacer automatically centres itself. The self-calibrated spherical bearings come pre-installed into the coupling parts. The spherical rubber elements are protected and have a long service life of up to one million kilometres of vehicle travel. They permit very large shaft displacements and allow major misalignments between the axle and the gear unit. The restoring forces that occur here are also very low. The fields of application are street-cars and locomotives. 7 www.jbj.co.uk/couplings.html#flender
© Wiener Linien 2 TIMES FIRST CLASS, PLEASE. The MBG membrane couplings impress due to their high level of concentricity and freedom from maintenance. FLENDER COUPLINGS RAIL COUPLINGS Flender membrane couplings from theMBGseries Flender MBG membrane couplings are two-part, torsionally rigid, all-steel couplings with excellent concentricity thanks to a special production process. Our MBG couplings are also balanced together with the motor rotor to give them outstanding balance quality. They are used to transmit torques and support the motor shaft in the gear unit. Their membrane contour gives them axial yield. The screw fitting makes it possible to detach or connect the motor and gear unit simply without loosening the interference fits. Their high concentricity and excellent balance quality are permanently retained thanks to the optimum centring of the gear teeth on the two coupling halves. Flender MBG drive train couplings are maintenance-free and are used for standard and low-floor streetcars. 8 www.jbj.co.uk/couplings.html#flender
The steel membrane couplings consist of two coupling halves that are connected by means of optimized selfcentring gear teeth. The torque is thus transmitted positively via the gear teeth. Due to optimized manufacturing, the membrane couplings have a very high level of concentricity, which is not impaired during reassembly. The couplings are generally balanced together with the rotor of the motor to ensure that potential additional influences during assembly are kept as low as possible. Slip hubs, speed sensors and also electric insulation of the coupling are available as additional options. The insulation is integrated into the coupling half on the gear unit side without additional components. The assembly process at the customer can be performed as for standard membrane couplings. Flender MBG-ISOmembrane couplings It is also possible to retrofit existing couplings with an electric earthing device. 9 www.jbj.co.uk/couplings.html#flender
WITHOUT ANY DELAYS. The Flender ARS all-steel multi-disk coupling can compensate for large misalignments and can be assembled and disassembled with very little effort. FLENDER COUPLINGS RAIL COUPLINGS An optimized conical bolt connection developed in-house is used to connect the disk packs to the respective coupling components. The components are assembled by means of both positive and non-positive connections. The tightening torques are low due to the optimized design of the bolted connection. In addition, due to the special form of the polygonal elements, an additional anti-rotation mechanism is not required during assembly, which also keeps the assembly effort low. Another positive effect here is the protection of the disks at the outer diameter against possible damage from stones or similar hazards. In general, the assembly effort is very low, as the main coupling components are delivered ready for installation ex-works. The all-steel multi-disk coupling is a torsionally rigid coupling that can compensate for large misalignments. In general, the coupling is compactly connected to the gear unit via a hollow-shaft connection and gear teeth. The motorside coupling half is connected to the motor shaft via an oil pressure interference fit. This ensures rapid assembly and disassembly. ADVANTAGES OF THE FLENDER ARS: » Form-closed bolt connection, low tightening torque. » Polygonal disk creates a bending line in order to compensate for the large misalignments. » Polygonal disk with impact protection during use. » Simple alignment during assembly. 10 www.jbj.co.uk/couplings.html#flender
