Flender is increasing the portfolio of its versatile coupling collection N-Eupex by introducing three new varieties. The new merchandise enable users additional flexibility in their systems without losing the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which supplies much more
safety within the drivetrain in many applications. The coupling variant permits users to
specify a most 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 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 by way of a clamping
connection and not utilizing a feather key and repair capacity is increased. For example,
meeting or replacement of worn elastomers could be carried out far more easily.
No connecting machine components have to 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 type, which was launched in
2020, addresses the pump market with normal expansion pieces for normed shaft
distances, the DKS is the shortest potential double-cardanic answer for the market.
The shortened overall size permits cost-optimized use with a small shaft distance
dimension without shedding some nice benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition
to the previously used rubber elements made of NBR, Flender now additionally 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 power density to be elevated by another 20 % on
average. For ไดอะแฟรม ซีล and above, the acquainted NBR elastomer is combined with
cloth inserts and the torque capability is once more raised.
“With a view to the long tradition of cam couplings, our improvement engineers are
systematically working on increasing the variety of mixtures even additional. The
2022 enhancements give our customers a extensive range of sustainable options for
optimizing their machines and systems even more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
