Flender is expanding the portfolio of its flexible coupling series N-Eupex by introducing three new sorts. The new merchandise enable users additional flexibility of their systems with out dropping the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which provides much more
safety within the drivetrain in many functions. The coupling variant allows customers to
specify a maximum torque in order that critical torques for the motor and output machine
usually are not transmitted. digital pressure gauge and techniques are protected from overload and
injury, thus significantly increasing 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 finish is linked to the coupling hub via a clamping
connection and not utilizing a feather key and repair capacity is elevated. For example,
assembly or substitute of worn elastomers may be carried out much more simply.
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 brand new double-cardanic coupling is launched as a “short
version” into Flender’s modular system. While the DK sort, which was launched in
2020, addresses the pump market with normal enlargement items for normed shaft
distances, the DKS is the shortest attainable double-cardanic solution for the market.
The shortened general size allows cost-optimized use with a small shaft distance
dimension without 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 also provides
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings allows the ability density to be elevated by one other 20 p.c on
average. For pressure gauge octa and above, the acquainted NBR elastomer is mixed with
material inserts and the torque capacity is once more raised.
“With a view to the long tradition of cam couplings, our improvement engineers are
systematically engaged on growing the number of combos even additional. The
2022 enhancements give our users a variety of sustainable options for
optimizing their machines and systems even more and lowering maintenance,”
explains André Artmann, Head of Coupling Sales.
