Three new N-Eupex couplings and optimised versatile elements

Flender is increasing the portfolio of its flexible coupling collection N-Eupex by introducing three new types. The new merchandise allow customers extra flexibility of their methods without dropping the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which supplies much more

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

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

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

damage, thus significantly rising system availability.
With the N-Eupex B plus clamping component, 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 without a feather key and repair capability is increased. For example,
meeting or substitute of worn elastomers can be carried out rather more easily.
No connecting machine parts must 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 launched as a “short

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

2020, addresses the pump market with standard growth pieces for normed shaft

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

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

to the beforehand used rubber elements made of NBR, Flender now also offers

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 elevated by one other 20 p.c on

average. For pressure gauge แบบ น้ำมัน and above, the acquainted NBR elastomer is combined with

material 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 number of mixtures even additional. The

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

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

explains André Artmann, Head of Coupling Sales.
