Three new N-Eupex couplings and optimised flexible parts

Flender is expanding the portfolio of its flexible coupling sequence N-Eupex by introducing three new varieties. The new merchandise enable customers further flexibility in their methods with out shedding the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which supplies even more
security in the drivetrain in many purposes. The coupling variant permits users to
specify a maximum torque in order that critical torques for the motor and output machine
aren’t transmitted. Machines and techniques are protected against overload and
harm, thus significantly growing 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 connected to the coupling hub by way of a clamping
connection with no feather key and repair ability is elevated. For example,
meeting or alternative of worn elastomers could be carried out much more simply.
No connecting machine parts should be moved, the time required is halved
and so is the downtime of the machine.
With the N-Eupex DKS, a 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 commonplace growth pieces for normed shaft
distances, the DKS is the shortest potential double-cardanic resolution for the market.
The shortened general length 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 previously used rubber parts made of NBR, Flender now additionally presents
elastomers made of thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, using TPU
packings permits the power density to be increased by another 20 percent on
common. For ที่วัดแรงดัน and above, the acquainted NBR elastomer is mixed with
material inserts and the torque capacity is again raised.
“With a view to the lengthy custom of cam couplings, our growth engineers are
systematically engaged on increasing the number of mixtures even further. The
2022 enhancements give our users a variety of sustainable options for
optimizing their machines and methods even more and lowering maintenance,”
explains André Artmann, Head of Coupling Sales.
