Three new N-Eupex couplings and optimised versatile elements

Flender is expanding the portfolio of its versatile coupling series N-Eupex by introducing three new sorts. The new products allow customers extra flexibility of their systems without losing the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which supplies much more
safety in the drivetrain in many purposes. เกจวัดแรงดันเชื้อเพลิง coupling variant permits users to
specify a most torque in order that critical torques for the motor and output machine
are not transmitted. Machines and systems are protected from overload and
damage, thus considerably rising 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 without a feather key and service ability is increased. For example,
meeting or substitute of worn elastomers could be carried out far more simply.
No connecting machine components 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 kind, which was launched in
2020, addresses the pump market with commonplace enlargement items for normed shaft
distances, the DKS is the shortest possible double-cardanic answer for the market.
The shortened general size enables 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 previously used rubber components made of NBR, Flender now also presents
elastomers made of thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings allows the power density to be elevated by another 20 percent on
average. For sizes 300 and above, the familiar NBR elastomer is mixed with
cloth inserts and the torque capability is again raised.
“With a view to the long custom of cam couplings, our development engineers are
systematically working on growing the variety of combos even additional. The
2022 enhancements give our customers a variety of sustainable options for
optimizing their machines and systems much more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
