Flender is expanding the portfolio of its versatile coupling series N-Eupex by introducing three new varieties. The new merchandise allow customers additional flexibility of their techniques without losing the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which provides even more
security in the drivetrain in many applications. The coupling variant permits customers to
specify a maximum torque so that critical torques for the motor and output machine
usually are not transmitted. Machines and techniques are shielded from overload and
injury, thus considerably rising 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 end is connected to the coupling hub by way of a clamping
connection with no feather key and repair capacity is elevated. For example,
meeting or alternative of worn elastomers can be carried out much more easily.
No connecting machine components have to 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 standard growth items for normed shaft
distances, the DKS is the shortest attainable double-cardanic resolution for the market.
The shortened general size enables cost-optimized use with a small shaft distance
dimension with out dropping the advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition
to the previously used rubber components made of NBR, Flender now additionally presents
elastomers manufactured from 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 increased by one other 20 p.c on
common. For pressure gauge ยี่ห้อ tk and above, the familiar NBR elastomer is mixed with
material inserts and the torque capacity is again raised.
“With a view to the lengthy custom of cam couplings, our development engineers are
systematically engaged on rising the variety of combos even additional. The
2022 enhancements give our users a variety of sustainable choices for
optimizing their machines and techniques even more and reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
