Three new N-Eupex couplings and optimised flexible parts

Flender is increasing the portfolio of its flexible coupling collection N-Eupex by introducing three new varieties. The new merchandise allow users further flexibility of their techniques with out losing the compact design and high load capacity of a pin coupling.
เกจวัดแรงดันถังออกซิเจน -Eupex ERN is equipped with a torque limiter, which provides much more
security in the drivetrain in plenty of functions. The coupling variant permits users to
specify a most torque in order that critical torques for the motor and output machine
aren’t transmitted. Machines and methods are protected from overload and
injury, thus considerably growing 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 through a clamping
connection without a feather key and service capacity is increased. For instance,
meeting or alternative of worn elastomers could be carried out much more simply.
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 brand 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 enlargement items for normed shaft
distances, the DKS is the shortest attainable double-cardanic solution for the market.
The shortened general length enables cost-optimized use with a small shaft distance
dimension with out dropping some nice benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition
to the previously used rubber parts made of NBR, Flender now additionally provides
elastomers made from thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, using TPU
packings allows the power density to be elevated by one other 20 p.c on
common. For sizes 300 and above, the familiar NBR elastomer is combined with
material inserts and the torque capability is again raised.
“With a view to the lengthy custom 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 techniques even more and decreasing upkeep,”
explains André Artmann, Head of Coupling Sales.
