Three new N-Eupex couplings and optimised versatile elements

Flender is increasing the portfolio of its flexible coupling collection N-Eupex by introducing three new types. The new products permit customers extra flexibility in their systems with out dropping the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which offers even more
safety in the drivetrain in many applications. The coupling variant permits customers to
specify a maximum torque in order that crucial torques for the motor and output machine
are not transmitted. Machines and methods are shielded from overload and
injury, thus significantly growing 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 related to the coupling hub by way of a clamping
connection without a feather key and service ability is elevated. For instance,
meeting or substitute of worn elastomers can be carried out rather more easily.
No connecting machine elements should 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 normal expansion pieces for normed shaft
distances, the DKS is the shortest possible double-cardanic solution 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 round off the modular extensions. In addition
to the beforehand used rubber parts made from NBR, Flender now also provides
elastomers made from thermoplastic polyurethane (TPU). Following จำหน่ายเกจวัดแรงดัน for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings allows the power density to be increased by another 20 % on
common. For sizes 300 and above, the familiar NBR elastomer is mixed with
fabric inserts and the torque capability is again raised.
“With a view to the long tradition of cam couplings, our growth engineers are
systematically engaged on increasing the variety of combinations even further. The
2022 enhancements give our users a variety of sustainable choices for
optimizing their machines and methods much more and reducing maintenance,”
explains André Artmann, Head of Coupling Sales.
