Three new N-Eupex couplings and optimised versatile parts

Flender is increasing the portfolio of its flexible coupling collection N-Eupex by introducing three new types. The new products permit users extra flexibility in their techniques without shedding the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which offers much more

safety within the drivetrain in many applications. The coupling variant permits customers to

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

aren’t transmitted. Machines and methods are shielded from overload and

injury, thus significantly rising system availability.
With the N-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 finish is linked to the coupling hub through a clamping

connection and not using a feather key and service ability is elevated. For example,
meeting or replacement of worn elastomers can be carried out rather 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 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 possible double-cardanic solution for the market.
The shortened total length enables cost-optimized use with a small shaft distance

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

to the previously used rubber parts made from 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, using TPU

packings permits the ability density to be increased by another 20 percent on

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

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

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

2022 enhancements give our customers a variety of sustainable options for

optimizing their machines and systems even more and lowering maintenance,”

explains André Artmann, Head of Coupling Sales.
