Three new N-Eupex couplings and optimised flexible components

เกจวัดแรงดันอาร์กอน is expanding the portfolio of its flexible coupling collection N-Eupex by introducing three new types. The new merchandise enable users further flexibility in their systems with out losing the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which provides much more
security in the drivetrain in plenty of functions. The coupling variant allows users to
specify a most torque so that important torques for the motor and output machine
usually are not transmitted. Machines and techniques are shielded from overload and
harm, thus significantly rising system availability.
With the N-Eupex B plus clamping component, Flender introduces a second new
coupling that ensures frictionally engaged clamping connections. In this case, the
plain, cylindrical machine shaft finish is related to the coupling hub through a clamping
connection without a feather key and repair capability is elevated. For instance,
meeting or substitute of worn elastomers could be carried out rather more easily.
No connecting machine elements have to 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 kind, which was launched in
2020, addresses the pump market with commonplace expansion pieces for normed shaft
distances, the DKS is the shortest attainable double-cardanic answer for the market.
The shortened total length permits cost-optimized use with a small shaft distance
dimension with out losing the benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition
to the beforehand used rubber components manufactured from NBR, Flender now also provides
elastomers made from thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings allows the power density to be increased by one other 20 % on
common. For sizes 300 and above, the acquainted NBR elastomer is mixed with
material inserts and the torque capability is again raised.
“With a view to the long custom of cam couplings, our development engineers are
systematically engaged on rising the variety of mixtures even additional. The
2022 enhancements give our customers a broad range of sustainable choices for
optimizing their machines and methods much more and reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
