Three new N-Eupex couplings and optimised flexible elements

Flender is increasing the portfolio of its flexible coupling series N-Eupex by introducing three new sorts. The new products allow users additional flexibility of their methods without dropping the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which offers even more

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

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

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

damage, thus significantly rising 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 related to the coupling hub via a clamping

connection and not using a feather key and service capacity is elevated. For instance,
meeting or substitute of worn elastomers could be carried out much more easily.
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 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 expansion items for normed shaft

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

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

to the beforehand used rubber elements manufactured from NBR, Flender now also presents

elastomers made of thermoplastic polyurethane (TPU). Following diaphragm seal for all N-Eupex couplings with NBR packings in 2020, the usage of TPU

packings allows the facility density to be increased by one other 20 p.c on

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

material inserts and the torque capacity is once more raised.
“With ไดอะแฟรม ซีล to the lengthy tradition of cam couplings, our growth engineers are

systematically engaged on increasing the variety of combos even additional. The

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

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

explains André Artmann, Head of Coupling Sales.
