Three new N-Eupex couplings and optimised versatile elements

Flender is expanding the portfolio of its versatile coupling series N-Eupex by introducing three new varieties. The new products allow users further flexibility in their techniques with out losing the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which offers even more
safety in the drivetrain in lots of purposes. The coupling variant allows customers to
specify a most torque so that crucial torques for the motor and output machine
are not transmitted. Machines and methods are shielded from overload and
damage, thus significantly growing 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 finish is linked to the coupling hub by way of a clamping
connection with no feather key and service capacity is elevated. For example,
meeting or substitute of worn elastomers can be carried out far more easily.
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 new double-cardanic coupling is launched as a “short
version” into Flender’s modular system. While the DK type, which was launched in
2020, addresses the pump market with commonplace enlargement items for normed shaft
distances, the DKS is the shortest potential double-cardanic solution for the market.
The shortened general length permits cost-optimized use with a small shaft distance
dimension with out losing some great 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 elements made from NBR, Flender now also offers
elastomers made of thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, the usage of TPU
packings allows the facility density to be increased by one other 20 % on
average. For เกรดวัดแรงดัน and above, the acquainted 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 growth engineers are
systematically engaged on increasing the number of mixtures even further. The
2022 enhancements give our customers a variety of sustainable choices for
optimizing their machines and techniques much more and reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
