Flender is expanding the portfolio of its flexible coupling collection N-Eupex by introducing three new sorts. The new merchandise permit users further flexibility of their techniques 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 lots of purposes. The coupling variant permits customers to
specify a maximum torque so that important torques for the motor and output machine
aren’t transmitted. Machines and methods are protected against overload and
harm, thus significantly rising system availability.
With pressure gauge 10 bar -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 without a feather key and repair capability is elevated. For example,
assembly or replacement of worn elastomers could be carried out far more simply.
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 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 standard expansion items for normed shaft
distances, the DKS is the shortest attainable double-cardanic solution for the market.
The shortened overall size enables cost-optimized use with a small shaft distance
dimension without 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 parts made of NBR, Flender now additionally provides
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 facility density to be increased by one other 20 % on
common. For sizes 300 and above, the acquainted NBR elastomer is combined with
fabric inserts and the torque capability is again raised.
“With a view to the lengthy tradition of cam couplings, our improvement engineers are
systematically working on increasing the number of combinations even further. The
2022 enhancements give our users a extensive range of sustainable options for
optimizing their machines and systems even more and decreasing maintenance,”
explains André Artmann, Head of Coupling Sales.
