Three new N-Eupex couplings and optimised versatile elements

Flender is increasing the portfolio of its versatile coupling collection N-Eupex by introducing three new types. The new products allow customers further flexibility of their methods without losing the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which provides much more
security in the drivetrain in lots of applications. The coupling variant allows users to
specify a maximum torque in order that critical torques for the motor and output machine
aren’t transmitted. Machines and methods are shielded from overload and
damage, 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 via a clamping
connection and not using a feather key and repair capability is elevated. For example,
meeting or substitute of worn elastomers could be carried out rather more simply.
No connecting machine elements 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 ที่วัดแรงดันน้ำ , which was launched in
2020, addresses the pump market with normal enlargement items for normed shaft
distances, the DKS is the shortest possible double-cardanic resolution 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 parts manufactured from NBR, Flender now also provides
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, the usage of TPU
packings permits the power density to be increased by another 20 p.c on
common. For sizes 300 and above, the familiar NBR elastomer is combined with
material inserts and the torque capacity is once more raised.
“With a view to the long custom of cam couplings, our improvement engineers are
systematically working on increasing the number of mixtures even further. The
2022 enhancements give our users a extensive range of sustainable options for
optimizing their machines and systems much more and reducing maintenance,”
explains André Artmann, Head of Coupling Sales.
