Three new N-Eupex couplings and optimised versatile elements

Flender is expanding the portfolio of its versatile coupling sequence N-Eupex by introducing three new types. The new products allow users extra flexibility of their techniques 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 supplies even more
security in the drivetrain in many purposes. The coupling variant permits customers to
specify a most torque so that crucial torques for the motor and output machine
are not transmitted. Machines and techniques are protected from overload and
damage, thus considerably increasing 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 end is linked to the coupling hub via a clamping
connection without a feather key and repair ability is increased. For example,
assembly or replacement of worn elastomers could be carried out much more easily.
No connecting machine components have to 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 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 resolution for the market.
The shortened total length enables cost-optimized use with a small shaft distance
dimension with out dropping the benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In เกจวัดแรงดันไอน้ำ
to the previously used rubber components manufactured from NBR, Flender now additionally provides
elastomers made from 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 elevated by another 20 % on
average. For sizes 300 and above, the acquainted NBR elastomer is combined with
material inserts and the torque capacity is again raised.
“With a view to the lengthy custom of cam couplings, our growth engineers are
systematically engaged on increasing the number of mixtures even further. The
2022 enhancements give our customers a broad range of sustainable options for
optimizing their machines and methods even more and decreasing maintenance,”
explains André Artmann, Head of Coupling Sales.
