Three new N-Eupex couplings and optimised flexible components

Flender is expanding the portfolio of its flexible coupling collection N-Eupex by introducing three new varieties. The new products permit customers extra flexibility of their methods 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 provides much more
security in the drivetrain in many purposes. The coupling variant allows users to
specify a most torque so that crucial torques for the motor and output machine
usually are not transmitted. Machines and methods are shielded from overload and
injury, thus considerably rising 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 end is linked to the coupling hub via a clamping
connection with no feather key and service ability is increased. For instance,
meeting or replacement of worn elastomers may be carried out much more easily.
pressure gauge 0 10 bar ราคา connecting machine components 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 introduced as a “short
version” into Flender’s modular system. While the DK type, which was launched in
2020, addresses the pump market with standard expansion pieces for normed shaft
distances, the DKS is the shortest possible double-cardanic answer for the market.
The shortened general 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 round off the modular extensions. In addition
to the previously used rubber elements made of NBR, Flender now also provides
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, the usage of TPU
packings permits the power density to be increased by one other 20 % on
common. For sizes 300 and above, the acquainted NBR elastomer is mixed with
material inserts and the torque capability is once more raised.
“With a view to the long tradition of cam couplings, our growth engineers are
systematically engaged on rising the number of combinations even further. The
2022 enhancements give our customers a variety of sustainable options for
optimizing their machines and systems even more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
