Three new N-Eupex couplings and optimised flexible components

Flender is expanding the portfolio of its versatile coupling sequence N-Eupex by introducing three new varieties. The new products allow users further flexibility of their techniques with out losing the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which supplies much more

security in the drivetrain in lots of functions. The coupling variant allows users to

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

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

damage, thus significantly increasing 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 and not using a feather key and service capability is elevated. For example,
meeting or substitute of worn elastomers could be carried out much more simply.
No connecting machine components 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 launched as a “short

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

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

distances, the DKS is the shortest possible double-cardanic solution for the market.
pressure gauge shortened total length allows cost-optimized use with a small shaft distance

dimension with out dropping some great 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 made from thermoplastic polyurethane (TPU). Following the torque

increase 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 mixed with

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

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

2022 enhancements give our customers a extensive range of sustainable options for

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

explains André Artmann, Head of Coupling Sales.
