Flender is increasing the portfolio of its flexible coupling sequence N-Eupex by introducing three new sorts. The new products allow users additional flexibility in their systems without dropping 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 functions. The coupling variant permits customers to
specify a maximum torque in order that critical torques for the motor and output machine
usually are not transmitted. Machines and methods are protected against overload and
injury, thus significantly increasing system availability.
With the N-Eupex B plus clamping component, Flender introduces a second new
coupling that ensures frictionally engaged clamping connections. In this case, the
plain, cylindrical machine shaft end is related to the coupling hub by way of a clamping
connection without a feather key and repair capacity is increased. For example,
meeting or replacement of worn elastomers could be carried out far more simply.
No connecting machine parts 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 standard enlargement items for normed shaft
distances, the DKS is the shortest possible double-cardanic answer for the market.
The shortened total length enables cost-optimized use with a small shaft distance
dimension without shedding the benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition
to the previously used rubber parts made from NBR, Flender now also provides
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, using TPU
packings allows the power density to be elevated by another 20 percent on
average. For sizes 300 and above, the acquainted NBR elastomer is mixed with
material inserts and the torque capacity is again raised.
“With pressure gauge น้ำ to the long custom of cam couplings, our development engineers are
systematically engaged on increasing the variety of mixtures even further. 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.
