Three new N-Eupex couplings and optimised versatile elements

Flender is expanding the portfolio of its versatile coupling series N-Eupex by introducing three new types. The new merchandise allow users extra flexibility in their methods with out dropping the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which provides much more

security within the drivetrain in many functions. The coupling variant allows users to

specify a most torque in order that critical torques for the motor and output machine

usually are not transmitted. Machines and techniques are protected against overload and

injury, thus significantly increasing system availability.
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 linked to the coupling hub via a clamping

connection with no feather key and repair capacity is elevated. For instance,
meeting or substitute of worn elastomers could be carried out much more easily.
No connecting machine elements have to be moved, the time required is halved

and so is the downtime of the machine.
With the N-Eupex DKS, a new double-cardanic coupling is launched as a “short

version” into Flender’s modular system. While the DK sort, which was launched in

2020, addresses the pump market with normal growth items for normed shaft

distances, the DKS is the shortest attainable double-cardanic solution for the market.
pressure gauge shortened total size allows cost-optimized use with a small shaft distance

dimension with out dropping some great advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition

to the previously used rubber parts made of NBR, Flender now also provides

elastomers made of thermoplastic polyurethane (TPU). Following the torque

enhance for all N-Eupex couplings with NBR packings in 2020, the use of TPU

packings permits the ability density to be increased by one other 20 % on

average. For sizes 300 and above, the acquainted NBR elastomer is combined with

fabric inserts and the torque capacity is once more raised.
“With a view to the long custom of cam couplings, our development engineers are

systematically engaged on increasing the variety of combos even additional. The

2022 enhancements give our users a wide range of sustainable choices for

optimizing their machines and systems even more and reducing upkeep,”

explains André Artmann, Head of Coupling Sales.
