Three new N-Eupex couplings and optimised versatile elements

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

security within the drivetrain in lots of functions. The coupling variant permits customers to

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

usually are not transmitted. Machines and techniques are protected from overload and

damage, thus considerably growing system availability.
With the N-Eupex B plus clamping component, Flender introduces a second new

coupling that ensures frictionally engaged clamping connections. In ไดอะแฟรม , the

plain, cylindrical machine shaft end is linked to the coupling hub by way of a clamping

connection with no feather key and service capacity is elevated. For example,
assembly or substitute of worn elastomers may be carried out much more simply.
No connecting machine parts 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 launched as a “short

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

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

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

dimension without shedding the advantages 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 of NBR, Flender now additionally presents

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

increase for all N-Eupex couplings with NBR packings in 2020, the utilization of TPU

packings allows the power density to be elevated by one other 20 % on

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

fabric inserts and the torque capacity is again raised.
“With a view to the long custom of cam couplings, our growth engineers are

systematically engaged on rising the variety of combos even further. The

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

optimizing their machines and methods much more and reducing upkeep,”

explains André Artmann, Head of Coupling Sales.
