Three new N-Eupex couplings and optimised versatile components

Flender is increasing the portfolio of its flexible coupling sequence N-Eupex by introducing three new types. The new merchandise enable customers additional flexibility of their methods without dropping the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which provides much more

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

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

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

harm, thus considerably rising system availability.
With the N-Eupex B plus clamping element, Flender introduces a second new

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

plain, cylindrical machine shaft end is related to the coupling hub via a clamping

connection without a feather key and service capacity is elevated. For example,
meeting or replacement of worn elastomers could be carried out much more simply.
No connecting machine elements must 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 growth items for normed shaft

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

dimension with out 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 parts made of NBR, Flender now also provides

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

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

packings permits the power density to be elevated by another 20 % on

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

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

systematically working on increasing the number of combos even additional. The

2022 enhancements give our users a variety of sustainable choices for

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

explains André Artmann, Head of Coupling Sales.
