Flender is expanding the portfolio of its flexible coupling collection N-Eupex by introducing three new varieties. The new products allow users extra flexibility of their methods with out losing the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which provides much more
safety within the drivetrain in plenty of applications. The coupling variant allows users to
specify a maximum torque in order that important torques for the motor and output machine
usually are not transmitted. Machines and systems are shielded from overload and
injury, thus significantly growing 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 through a clamping
connection without a feather key and service capacity is elevated. For instance,
assembly or alternative of worn elastomers can be carried out rather more simply.
No connecting machine components 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 type, which was launched in
2020, addresses the pump market with commonplace expansion items for normed shaft
distances, the DKS is the shortest potential double-cardanic resolution for the market.
The shortened total length permits cost-optimized use with a small shaft distance
dimension without shedding 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 elements manufactured from NBR, Flender now also offers
elastomers made from thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings allows the power density to be elevated by one other 20 % on
average. For sizes 300 and above, the acquainted NBR elastomer is mixed with
fabric inserts and the torque capacity is once more raised.
“With ไดอะแฟรม to the long tradition of cam couplings, our growth engineers are
systematically engaged on rising the variety of mixtures even further. The
2022 enhancements give our customers a variety of sustainable choices for
optimizing their machines and methods much more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
