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 merchandise permit customers additional flexibility in their systems with out dropping the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which offers even more
security within the drivetrain in many applications. The coupling variant allows users to
specify a most torque in order that critical torques for the motor and output machine
are not transmitted. Machines and methods are protected against overload and
injury, 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 end is linked to the coupling hub via a clamping
connection and not utilizing a feather key and service ability is elevated. For example,
meeting or substitute of worn elastomers may be carried out far more easily.
No connecting machine components should be moved, the time required is halved
and so is the downtime of the machine.
With the N-Eupex DKS, a model new double-cardanic coupling is introduced as a “short
version” into Flender’s modular system. While the DK type, which was launched in
2020, addresses the pump market with standard expansion pieces for normed shaft
distances, the DKS is the shortest attainable double-cardanic answer for the market.
เกจวัดแรงลม shortened general 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 beforehand used rubber parts made of NBR, Flender now also presents
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 permits the facility density to be elevated by one other 20 p.c on
common. For sizes 300 and above, the acquainted NBR elastomer is mixed with
cloth inserts and the torque capacity is once more raised.
“With a view to the long custom of cam couplings, our growth engineers are
systematically working on growing the variety of combinations even additional. The
2022 enhancements give our users a wide range of sustainable options for
optimizing their machines and techniques even more and reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
