Three new N-Eupex couplings and optimised flexible parts

Flender is expanding the portfolio of its flexible coupling series N-Eupex by introducing three new sorts. The new merchandise enable customers extra flexibility of their systems with out dropping the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which provides much more
safety in the drivetrain in many applications. The coupling variant allows users to
specify a maximum torque in order that important torques for the motor and output machine
aren’t transmitted. Machines and methods are shielded from overload and
harm, thus considerably rising 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 related to the coupling hub through a clamping
connection and not utilizing a feather key and repair capability is increased. For ตัววัดแรงดัน ,
meeting or substitute of worn elastomers can be carried out far more easily.
No connecting machine parts must 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 commonplace enlargement items 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 shedding the benefits 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 additionally provides
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings permits the power density to be elevated by another 20 p.c on
average. For sizes 300 and above, the familiar NBR elastomer is mixed with
cloth inserts and the torque capacity is once more raised.
“With a view to the lengthy tradition of cam couplings, our development engineers are
systematically engaged on rising the number of mixtures even additional. The
2022 enhancements give our customers a extensive range of sustainable options for
optimizing their machines and techniques even more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
