Three new N-Eupex couplings and optimised flexible parts

pressure gauge 10 bar is expanding the portfolio of its flexible coupling series N-Eupex by introducing three new varieties. The new products allow customers additional flexibility in their methods without losing the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which supplies even more

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

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

are not transmitted. Machines and techniques are protected against overload and

damage, thus significantly growing 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 end is related to the coupling hub via a clamping

connection with no feather key and repair capability is elevated. For instance,
assembly or replacement of worn elastomers can be carried out far more simply.
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 introduced as a “short

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

2020, addresses the pump market with standard enlargement items for normed shaft

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

dimension without losing the advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition

to the beforehand used rubber components made from NBR, Flender now also presents

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

enhance for all N-Eupex couplings with NBR packings in 2020, using TPU

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

common. For sizes 300 and above, the familiar NBR elastomer is combined with

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

systematically engaged on growing the number of combinations even further. The

2022 enhancements give our customers a variety of sustainable options for

optimizing their machines and systems much more and decreasing upkeep,”

explains André Artmann, Head of Coupling Sales.
