Three new N-Eupex couplings and optimised flexible components

Flender is expanding the portfolio of its flexible coupling collection N-Eupex by introducing three new types. เกจ์วัดความดัน allow users extra flexibility of their systems with out dropping the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which offers even more
safety within the drivetrain in many purposes. The coupling variant allows customers to
specify a most torque in order that important torques for the motor and output machine
are not transmitted. Machines and techniques are protected against overload and
damage, 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 connected to the coupling hub via a clamping
connection with no feather key and service capability is increased. For example,
meeting or substitute of worn elastomers may be carried out much 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 brand 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 enlargement pieces for normed shaft
distances, the DKS is the shortest attainable double-cardanic answer for the market.
The shortened overall size enables cost-optimized use with a small shaft distance
dimension with out dropping some great benefits 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 made of NBR, Flender now also offers
elastomers made of thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, using TPU
packings allows the power density to be elevated by another 20 percent on
common. For sizes 300 and above, the familiar NBR elastomer is combined with
material inserts and the torque capability is once more raised.
“With a view to the lengthy tradition of cam couplings, our improvement engineers are
systematically working on increasing the variety of mixtures even further. The
2022 enhancements give our users a variety of sustainable choices for
optimizing their machines and techniques even more and lowering maintenance,”
explains André Artmann, Head of Coupling Sales.
