N-Eupex ERN The new N-Eupex ERN is equipped with a torque limiter, which provides even more security in the drivetrain in many applications. The coupling variant allows users to specify a maximum torque so that critical torques for the motor and output machine are not transmitted. Machines and systems are protected from overload and damage, thus significantly increasing system availability.

N-Eupex B with clamping element With the N-Eupex B plus clamping element, Flender introduces a second new coupling that ensures frictionally engaged clamping connections. In this case, the plain, cylindrical machine shaft end is connected to the coupling hub via a clamping connection without a feather key and service ability is increased. For example, assembly or replacement of worn elastomers can be carried out much more easily. No connecting machine components must be moved, the time required is halved and so is the downtime of the machine.

N-Eupex DKS With the N-Eupex DKS, a new double-cardanic coupling is introduced as a "short version" into Flender’s modular system. While the DK type, which was launched in 2020, addresses the pump market with standard expansion pieces for normed shaft distances, the DKS is the shortest possible double-cardanic solution for the market. The shortened overall length enables cost-optimized use with a small shaft distance dimension without losing the advantages of a double-cardanic coupling connection.

Extension of elastomers New elastomers for the pin couplings round off the modular extensions. In addition to the previously used rubber elements made of NBR, Flender now also offers elastomers made of thermoplastic polyurethane (TPU). Following the torque increase for all N-Eupex couplings with NBR packings in 2020, the use of TPU packings allows the power density to be increased by another 20 percent on average. For sizes 300 and above, the familiar NBR elastomer is combined with fabric inserts and the torque capacity is again raised.

"With a view to the long tradition of cam couplings, our development engineers are systematically working on increasing the variety of combinations even further. The 2022 enhancements give our users a wide range of sustainable options for optimizing their machines and systems even more and reducing maintenance," explains André Artmann, Head of Coupling Sales.

AUMA’s proven electric actuation technology is helping to boost green energy in Taiwan. 40 AUMA actuators are installed at Qingshui, Taiwan’s first new-generation geothermal power plant. The operator’s decision was based on AUMA’s excellent product quality and professional after sales service.

With the symbolic groundbreaking, drive manufacturer Flender has officially started construction work on the expansion of its German site in Voerde on the Lower Rhine.

With a festive groundbreaking ceremony, Flender officially started work on the expansion of production capacities for wind drive systems at its site in Tianjin, China.

With the ROFLEX KTR launches a new shaft coupling according to DIN 740 which is characterised by its short design and its service-friendliness. In addition to power transmission, the torsionally flexible coupling compensates for misalignments and dampens torsional vibrations.
