Flender is increasing the portfolio of its flexible coupling series N-Eupex by introducing three new varieties. The new products allow customers further flexibility in their systems without losing the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which offers even more
security in 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
usually are not transmitted. xp2i and methods are protected from overload and
damage, thus significantly growing 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 via a clamping
connection without a feather key and repair capability is increased. For example,
meeting or alternative of worn elastomers could be carried out far more simply.
No connecting machine parts 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 kind, which was launched in
2020, addresses the pump market with standard expansion pieces for normed shaft
distances, the DKS is the shortest attainable double-cardanic resolution for the market.
The shortened general size permits cost-optimized use with a small shaft distance
dimension without shedding some great 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 components manufactured from NBR, Flender now additionally 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 ability density to be elevated by one other 20 p.c on
common. For sizes 300 and above, the acquainted NBR elastomer is mixed with
material 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 rising the number 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 upkeep,”
explains André Artmann, Head of Coupling Sales.
