Flender is expanding the portfolio of its flexible coupling sequence N-Eupex by introducing three new sorts. The new products enable users further flexibility of their systems with out shedding the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which supplies much more
security within the drivetrain in lots of functions. The coupling variant permits customers to
specify a maximum torque so that crucial torques for the motor and output machine
usually are not transmitted. Machines and techniques are protected from overload and
damage, 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 ไดอะแฟรม , the
plain, cylindrical machine shaft end is linked to the coupling hub by way of a clamping
connection with no feather key and service capacity is elevated. For example,
assembly or substitute of worn elastomers may be carried out much more simply.
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 brand new double-cardanic coupling is launched as a “short
version” into Flender’s modular system. While the DK sort, which was launched in
2020, addresses the pump market with commonplace growth pieces for normed shaft
distances, the DKS is the shortest attainable double-cardanic solution for the market.
The shortened overall size enables 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 made of NBR, Flender now additionally presents
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, the utilization of TPU
packings allows the power density to be elevated by one other 20 % on
average. For sizes 300 and above, the acquainted NBR elastomer is combined with
fabric inserts and the torque capacity is again raised.
“With a view to the long custom of cam couplings, our growth engineers are
systematically engaged on rising the variety of combos even further. The
2022 enhancements give our users a wide range of sustainable choices for
optimizing their machines and methods much more and reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
