Three new N-Eupex couplings and optimised flexible elements

Flender is increasing the portfolio of its versatile coupling collection N-Eupex by introducing three new sorts. The new products allow users further flexibility in their techniques without shedding the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which offers even more
safety in the drivetrain in lots of functions. The coupling variant permits users to
specify a maximum torque so that critical torques for the motor and output machine
aren’t transmitted. Machines and systems are protected from overload and
injury, thus significantly increasing 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 end is connected to the coupling hub through a clamping
connection with no feather key and service ability is increased. For example,
meeting or replacement of worn elastomers could be carried out much more easily.
No connecting machine elements must 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 pressure gauge น้ำ , which was launched in
2020, addresses the pump market with commonplace enlargement pieces for normed shaft
distances, the DKS is the shortest potential double-cardanic resolution for the market.
The shortened general size enables cost-optimized use with a small shaft distance
dimension with out 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 manufactured from NBR, Flender now additionally provides
elastomers manufactured from 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 one other 20 percent on
average. For sizes 300 and above, the familiar NBR elastomer is combined with
fabric inserts and the torque capacity is once more raised.
“With a view to the lengthy tradition of cam couplings, our improvement engineers are
systematically engaged on growing the variety of combinations even further. The
2022 enhancements give our customers a variety of sustainable options for
optimizing their machines and systems much more and lowering maintenance,”
explains André Artmann, Head of Coupling Sales.
