Three new N-Eupex couplings and optimised flexible elements

Flender is increasing the portfolio of its versatile coupling sequence N-Eupex by introducing three new sorts. The new merchandise permit customers further flexibility in their techniques with out losing the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which offers even more
security within the drivetrain in many applications. The coupling variant permits customers to
specify a maximum torque in order that important torques for the motor and output machine
are not transmitted. Machines and systems are shielded from overload and
harm, thus considerably growing system availability.
With เครื่องมือที่ใช้ในการวัดความดัน -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 with no feather key and repair capability is increased. For instance,
assembly or substitute of worn elastomers could be carried out much more easily.
No connecting machine elements should be moved, the time required is halved
and so is the downtime of the machine.
With the N-Eupex DKS, a model 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 growth pieces for normed shaft
distances, the DKS is the shortest attainable double-cardanic solution for the market.
The shortened overall length permits cost-optimized use with a small shaft distance
dimension with out shedding the 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 elements made of NBR, Flender now also offers
elastomers made from thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings permits the ability density to be elevated by one other 20 p.c on
common. For sizes 300 and above, the acquainted NBR elastomer is combined with
cloth inserts and the torque capacity is once more raised.
“With a view to the long custom of cam couplings, our growth engineers are
systematically engaged on rising the number of mixtures even additional. The
2022 enhancements give our customers a wide range of sustainable options for
optimizing their machines and techniques even more and reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
