Three new N-Eupex couplings and optimised flexible elements

Flender is increasing the portfolio of its versatile coupling series N-Eupex by introducing three new sorts. The new products permit customers extra flexibility in their techniques without dropping the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which supplies much more
security in the drivetrain in plenty of functions. The coupling variant permits customers to
specify a most torque in order that critical torques for the motor and output machine
aren’t transmitted. Machines and methods are protected from overload and
harm, thus considerably growing 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 connected to the coupling hub by way of a clamping
connection with no feather key and repair capacity is elevated. For example,
meeting or alternative of worn elastomers can be carried out far more simply.
เครื่องมือความดัน 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 brand 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 commonplace expansion items for normed shaft
distances, the DKS is the shortest potential double-cardanic solution for the market.
The shortened general size enables cost-optimized use with a small shaft distance
dimension with out shedding the benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition
to the previously used rubber elements made from NBR, Flender now additionally offers
elastomers made of thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, using TPU
packings permits the ability density to be elevated by another 20 percent on
common. For sizes 300 and above, the familiar NBR elastomer is mixed with
fabric inserts and the torque capability is once more raised.
“With a view to the long custom of cam couplings, our development engineers are
systematically working on rising the variety of mixtures even additional. The
2022 enhancements give our customers a extensive range of sustainable choices for
optimizing their machines and techniques much more and lowering maintenance,”
explains André Artmann, Head of Coupling Sales.
