Three new N-Eupex couplings and optimised versatile elements

Flender is increasing the portfolio of its versatile coupling collection N-Eupex by introducing three new types. The new merchandise enable customers additional flexibility of their systems with out losing the compact design and high 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 plenty of purposes. The coupling variant allows customers to

specify a maximum torque so that crucial torques for the motor and output machine

aren’t transmitted. Machines and techniques are protected from overload and

injury, thus considerably rising system availability.
With pressure gauge octa -Eupex B plus clamping factor, 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 repair capability is increased. For instance,
assembly or substitute of worn elastomers could be carried out far more easily.
No connecting machine parts have to be moved, the time required is halved

and so is the downtime of the machine.
With the N-Eupex DKS, a model 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 commonplace growth items for normed shaft

distances, the DKS is the shortest attainable double-cardanic solution for the market.
The shortened overall size permits cost-optimized use with a small shaft distance

dimension without losing the advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition

to the beforehand used rubber elements made from NBR, Flender now additionally provides

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

enhance for all N-Eupex couplings with NBR packings in 2020, using TPU

packings permits the facility density to be increased by one other 20 p.c on

common. For sizes 300 and above, the familiar NBR elastomer is combined with

cloth inserts and the torque capability is again raised.
“With a view to the lengthy custom of cam couplings, our growth engineers are

systematically working on rising the variety of combinations even additional. The

2022 enhancements give our customers a extensive range of sustainable choices for

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

explains André Artmann, Head of Coupling Sales.
