Three new N-Eupex couplings and optimised flexible components

Flender is increasing the portfolio of its flexible coupling series N-Eupex by introducing three new sorts. The new merchandise allow users further flexibility of their systems without losing the compact design and excessive load capacity of a pin coupling.
เครื่องมือที่ใช้วัดความดันเลือด -Eupex ERN is supplied with a torque limiter, which offers even more
security within the drivetrain in many purposes. The coupling variant allows customers to
specify a most torque so that important torques for the motor and output machine
are not transmitted. Machines and techniques are protected against overload and
harm, thus significantly increasing 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 end is related to the coupling hub by way of a clamping
connection without a feather key and repair ability is elevated. For example,
assembly or replacement of worn elastomers can be carried out far more simply.
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 introduced as a “short
version” into Flender’s modular system. While the DK type, which was launched in
2020, addresses the pump market with commonplace growth pieces for normed shaft
distances, the DKS is the shortest attainable double-cardanic solution for the market.
The shortened overall size enables cost-optimized use with a small shaft distance
dimension with out losing some nice 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 manufactured from NBR, Flender now additionally provides
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings allows the ability density to be increased by another 20 % on
common. For sizes 300 and above, the familiar NBR elastomer is combined with
fabric inserts and the torque capability is again raised.
“With a view to the lengthy tradition of cam couplings, our development engineers are
systematically engaged on rising the number of mixtures even additional. The
2022 enhancements give our users a variety of sustainable options for
optimizing their machines and techniques even more and reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
