Three new N-Eupex couplings and optimised flexible parts

Flender is increasing the portfolio of its versatile coupling series N-Eupex by introducing three new varieties. The new products enable users extra flexibility in their methods without losing the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which provides much more
security in the drivetrain in plenty of applications. เกจวัดแรงดันไอน้ำ coupling variant permits 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 protected from overload and
injury, thus considerably 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 finish is related to the coupling hub by way of a clamping
connection and not utilizing a feather key and repair ability is elevated. For example,
meeting or replacement of worn elastomers could be carried out far more easily.
No connecting machine elements 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 type, which was launched in
2020, addresses the pump market with commonplace enlargement pieces for normed shaft
distances, the DKS is the shortest potential double-cardanic answer for the market.
The shortened total size enables cost-optimized use with a small shaft distance
dimension with out dropping 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 components made from NBR, Flender now additionally presents
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, using TPU
packings permits the ability density to be elevated by one other 20 p.c on
average. For sizes 300 and above, the familiar NBR elastomer is mixed with
material inserts and the torque capacity is again raised.
“With a view to the long tradition of cam couplings, our improvement engineers are
systematically working on increasing the variety of mixtures even additional. The
2022 enhancements give our customers a variety of sustainable choices for
optimizing their machines and techniques much more and reducing maintenance,”
explains André Artmann, Head of Coupling Sales.
