Three new N-Eupex couplings and optimised versatile components

Flender is increasing the portfolio of its versatile coupling series N-Eupex by introducing three new varieties. The new products enable customers extra flexibility in their methods without dropping the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which provides even more
security in the drivetrain in plenty of functions. The coupling variant permits users to
specify a most torque so that important torques for the motor and output machine
usually are not transmitted. Machines and methods are protected against overload and
harm, thus considerably 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 finish is connected to the coupling hub by way of a clamping
connection and not using a feather key and repair ability is elevated. For example,
meeting or substitute of worn elastomers may be carried out far more easily.
Frenzy 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 normal growth items for normed shaft
distances, the DKS is the shortest potential double-cardanic solution for the market.
The shortened overall length 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 elements manufactured from NBR, Flender now additionally presents
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings permits the facility density to be increased by one other 20 percent on
common. For sizes 300 and above, the acquainted NBR elastomer is mixed with
fabric inserts and the torque capacity is once more raised.
“With a view to the long custom of cam couplings, our development engineers are
systematically engaged on growing the number of combos even additional. The
2022 enhancements give our users a variety of sustainable choices for
optimizing their machines and systems even more and decreasing maintenance,”
explains André Artmann, Head of Coupling Sales.
