Three new N-Eupex couplings and optimised flexible parts

Flender is expanding the portfolio of its flexible coupling collection N-Eupex by introducing three new types. The new products allow users further flexibility of their methods with out dropping the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which provides much more
safety in the drivetrain in many purposes. The coupling variant permits customers to
specify a most torque so that critical torques for the motor and output machine
usually are not transmitted. Machines and techniques are shielded from overload and
damage, 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 finish is related to the coupling hub through a clamping
connection and not using a feather key and repair capability is elevated. For เกจ์แรงดัน ,
assembly or substitute of worn elastomers can be carried out much more easily.
No connecting machine parts should 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 sort, which was launched in
2020, addresses the pump market with commonplace expansion pieces for normed shaft
distances, the DKS is the shortest attainable double-cardanic resolution for the market.
The shortened total size permits 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 manufactured from NBR, Flender now also presents
elastomers made from thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, the utilization of TPU
packings permits the facility density to be elevated by another 20 p.c on
average. For sizes 300 and above, the acquainted NBR elastomer is combined with
cloth inserts and the torque capacity is again raised.
“With weksler ea14 to the long tradition of cam couplings, our growth engineers are
systematically engaged on rising the variety of combos even further. The
2022 enhancements give our customers a variety of sustainable choices for
optimizing their machines and techniques even more and decreasing upkeep,”
explains André Artmann, Head of Coupling Sales.
