Three new N-Eupex couplings and optimised flexible elements

Flender is increasing the portfolio of its flexible coupling series N-Eupex by introducing three new types. The new products enable users extra flexibility of their methods with out dropping the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which provides even more
security in the drivetrain in many applications. The coupling variant allows users to
specify a most torque so that crucial torques for the motor and output machine
aren’t transmitted. Machines and techniques are protected against overload and
injury, thus considerably rising 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 by way of a clamping
connection with no feather key and service ability is increased. For example,
meeting or alternative of worn elastomers could be carried out far more simply.
เกจวัดแก๊ส 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 new double-cardanic coupling is introduced as a “short
version” into Flender’s modular system. While the DK kind, which was launched in
2020, addresses the pump market with normal expansion pieces for normed shaft
distances, the DKS is the shortest potential double-cardanic answer for the market.
The shortened general length allows cost-optimized use with a small shaft distance
dimension without shedding some great 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 parts made from NBR, Flender now also provides
elastomers made of thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, the use 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
fabric inserts and the torque capacity is once more raised.
“With a view to the long custom of cam couplings, our improvement engineers are
systematically working on growing the number of combinations even further. The
2022 enhancements give our users a variety of sustainable choices for
optimizing their machines and systems much more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
