Three new N-Eupex couplings and optimised flexible parts

Flender is increasing the portfolio of its flexible coupling series N-Eupex by introducing three new sorts. pressure gauge ด้าน ดูด allow users additional flexibility of their techniques with out losing the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which provides much more
security within the drivetrain in many purposes. The coupling variant allows customers to
specify a maximum torque so that critical torques for the motor and output machine
aren’t transmitted. Machines and methods are protected against overload and
injury, thus considerably rising 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 without a feather key and repair capability is elevated. For instance,
assembly or substitute of worn elastomers can be carried out rather more simply.
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 model new double-cardanic coupling is introduced as a “short
version” into Flender’s modular system. While the DK kind, which was launched in
2020, addresses the pump market with commonplace growth items for normed shaft
distances, the DKS is the shortest attainable double-cardanic answer for the market.
The shortened general length allows cost-optimized use with a small shaft distance
dimension without losing the 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 additionally offers
elastomers made from thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, the usage of TPU
packings permits the facility density to be increased by another 20 percent on
average. For sizes 300 and above, the familiar NBR elastomer is combined with
cloth inserts and the torque capability is once more raised.
“With a view to the lengthy tradition of cam couplings, our development engineers are
systematically engaged on growing the number of combinations even further. The
2022 enhancements give our customers a wide range of sustainable choices for
optimizing their machines and techniques much more and reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
