Three new N-Eupex couplings and optimised versatile elements

Flender is expanding the portfolio of its flexible coupling series N-Eupex by introducing three new sorts. The new merchandise enable users additional flexibility of their systems with out dropping the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which provides much more

safety within the drivetrain in many functions. The coupling variant allows customers to

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

usually are not transmitted. digital pressure gauge and techniques are protected from 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 finish is linked to the coupling hub via a clamping

connection and not utilizing a feather key and repair capacity is elevated. For example,
assembly or substitute of worn elastomers may be carried out much more simply.
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 brand 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 enlargement items for normed shaft

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

dimension without 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 components made of NBR, Flender now also provides

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

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

packings allows the ability density to be elevated by one other 20 p.c on

average. For pressure gauge octa and above, the acquainted NBR elastomer is mixed with

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

systematically engaged on growing the number of combos even additional. The

2022 enhancements give our users a variety of sustainable options for

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

explains André Artmann, Head of Coupling Sales.
