Three new N-Eupex couplings and optimised versatile elements

Flender is expanding the portfolio of its versatile coupling series N-Eupex by introducing three new varieties. The new products permit users further flexibility in their systems with out shedding the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which supplies much more
safety in the drivetrain in many functions. The coupling variant permits customers to
specify a maximum torque so that crucial torques for the motor and output machine
usually are not transmitted. Machines and techniques are protected from overload and
damage, 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 linked to the coupling hub by way of a clamping
connection and not using a feather key and repair ability is elevated. For instance,
assembly or substitute of worn elastomers can be carried out rather more easily.
compound gauge ราคา connecting machine parts have to 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 sort, which was launched in
2020, addresses the pump market with standard expansion pieces for normed shaft
distances, the DKS is the shortest potential double-cardanic resolution for the market.
The shortened total length 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 round off the modular extensions. In addition
to the beforehand used rubber components made of NBR, Flender now additionally provides
elastomers made of thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings allows the facility density to be elevated by one other 20 % 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 lengthy custom of cam couplings, our growth engineers are
systematically working on rising the number of mixtures even additional. The
2022 enhancements give our customers a variety of sustainable choices for
optimizing their machines and methods even more and decreasing upkeep,”
explains André Artmann, Head of Coupling Sales.
