Three new N-Eupex couplings and optimised flexible components

Flender is expanding the portfolio of its flexible coupling series N-Eupex by introducing three new types. The new products permit customers extra flexibility in their methods with out losing the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which provides even more

security within the drivetrain in many purposes. The coupling variant allows users to

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

are not transmitted. pressure gauge octa and systems are protected against overload and

harm, thus considerably increasing 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 finish is linked to the coupling hub via a clamping

connection and not using a feather key and repair capacity is elevated. For example,
assembly or replacement of worn elastomers may 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 ไดอะแฟรม -Eupex DKS, a 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 commonplace expansion items for normed shaft

distances, the DKS is the shortest attainable double-cardanic resolution for the market.
The shortened total length enables 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 previously used rubber elements made of NBR, Flender now also offers

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

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

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

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

fabric inserts and the torque capacity is once more raised.
“With a view to the lengthy tradition of cam couplings, our development engineers are

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

2022 enhancements give our users a broad range of sustainable options for

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

explains André Artmann, Head of Coupling Sales.
