Three new N-Eupex couplings and optimised versatile elements

Flender is expanding the portfolio of its versatile coupling collection N-Eupex by introducing three new types. The new merchandise allow users further flexibility in their methods 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 offers much more
security within the drivetrain in lots of functions. The coupling variant permits customers to
specify a most torque in order that critical torques for the motor and output machine
usually are not transmitted. Machines and methods are shielded from overload and
injury, thus significantly growing 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 related to the coupling hub via a clamping
connection without a feather key and repair capability is increased. For เกจวัดแรงดันแก๊ส ,
assembly or replacement of worn elastomers could be carried out rather more easily.
No connecting machine elements have to be moved, the time required is halved
and so is the downtime of the machine.
With the N-Eupex DKS, a model 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 pieces for normed shaft
distances, the DKS is the shortest possible double-cardanic answer for the market.
The shortened total length permits cost-optimized use with a small shaft distance
dimension with out losing 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 manufactured from NBR, Flender now additionally presents
elastomers made of thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, using TPU
packings allows the facility density to be elevated by another 20 percent 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 lengthy tradition of cam couplings, our improvement engineers are
systematically working on rising the variety of mixtures even additional. The
2022 enhancements give our users a variety of sustainable options for
optimizing their machines and techniques even more and reducing maintenance,”
explains André Artmann, Head of Coupling Sales.
