Flender is increasing the portfolio of its versatile coupling collection N-Eupex by introducing three new varieties. The new merchandise enable users extra flexibility in their techniques without losing the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which provides even more
security in the drivetrain in many purposes. The coupling variant permits users to
specify a maximum torque in order that crucial torques for the motor and output machine
aren’t transmitted. Machines and systems are protected against overload and
injury, thus significantly rising 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 end is related to the coupling hub by way of a clamping
connection and not using a feather key and service capacity is increased. For instance,
meeting or substitute of worn elastomers may be carried out much more simply.
No connecting machine elements must 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 sort, which was launched in
2020, addresses the pump market with normal growth items for normed shaft
distances, the DKS is the shortest attainable double-cardanic solution for the market.
The shortened overall size allows cost-optimized use with a small shaft distance
dimension without shedding the 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 components made of NBR, Flender now also offers
elastomers made from thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, the usage of TPU
packings allows the facility density to be increased by one other 20 % on
common. For sizes 300 and above, the familiar NBR elastomer is combined with
cloth inserts and the torque capacity is once more raised.
“With diaphragm seal to the lengthy custom of cam couplings, our growth engineers are
systematically working on increasing the number of combos even further. The
2022 enhancements give our customers a variety of sustainable choices for
optimizing their machines and techniques even more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
