Three new N-Eupex couplings and optimised flexible elements

Flender is increasing the portfolio of its flexible coupling collection N-Eupex by introducing three new types. The new merchandise allow customers additional flexibility in their methods without losing the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which offers much more
safety within the drivetrain in many functions. The coupling variant permits users to
specify a most torque so that critical torques for the motor and output machine
aren’t transmitted. Machines and methods are protected against 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 this case, the
plain, cylindrical machine shaft finish is linked to the coupling hub through a clamping
connection without a feather key and repair ability is increased. For example,
meeting or alternative of worn elastomers could be carried out much more simply.
No connecting machine elements should 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 type, which was launched in
2020, addresses the pump market with commonplace growth pieces for normed shaft
distances, the DKS is the shortest potential double-cardanic resolution for the market.
เครื่องมือที่ใช้ในการวัดความดัน shortened total length allows cost-optimized use with a small shaft distance
dimension without 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 made of NBR, Flender now also offers
elastomers made of thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, the utilization of TPU
packings allows the ability 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 once more raised.
“With a view to the lengthy tradition of cam couplings, our improvement engineers are
systematically working on increasing the variety of combinations even further. The
2022 enhancements give our customers a broad range of sustainable choices for
optimizing their machines and techniques even more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
