Three new N-Eupex couplings and optimised versatile parts

Flender is expanding the portfolio of its flexible coupling series N-Eupex by introducing three new types. The new products enable users additional flexibility in their methods with out losing the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which provides much more

security within the drivetrain in lots of applications. The coupling variant allows customers to

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

usually are not transmitted. Machines and methods are shielded from overload and

damage, 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 เพรสเชอร์เกจ , the

plain, cylindrical machine shaft finish is linked to the coupling hub through a clamping

connection and not using a feather key and repair capability is elevated. For example,
meeting or alternative of worn elastomers can be carried out rather more easily.
No connecting machine elements should be moved, the time required is halved

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

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

dimension with out shedding the benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition

to the previously used rubber components made of NBR, Flender now also presents

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

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

packings permits the power density to be elevated by one other 20 p.c on

common. For pressure gauge and above, the acquainted NBR elastomer is combined with

cloth inserts and the torque capacity is once more raised.
“With a view to the long tradition of cam couplings, our improvement engineers are

systematically working on growing the number of combos even further. The

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

optimizing their machines and techniques even more and decreasing maintenance,”

explains André Artmann, Head of Coupling Sales.
