Three new N-Eupex couplings and optimised flexible components

Flender is expanding the portfolio of its flexible coupling series N-Eupex by introducing three new varieties. เกจวัดแรง enable customers extra flexibility of their systems without losing the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which supplies even more
security in the drivetrain in many purposes. The coupling variant allows customers to
specify a maximum torque so that important torques for the motor and output machine
usually are not transmitted. Machines and techniques are protected against 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 finish is related to the coupling hub through a clamping
connection with no feather key and repair capacity is increased. For example,
meeting or substitute 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 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 standard growth pieces for normed shaft
distances, the DKS is the shortest potential double-cardanic solution for the market.
The shortened overall size allows cost-optimized use with a small shaft distance
dimension with out shedding the advantages 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 use of TPU
packings permits the ability density to be increased by one other 20 p.c on
common. For sizes 300 and above, the acquainted NBR elastomer is combined with
fabric inserts and the torque capability is once more raised.
“With a view to the lengthy custom of cam couplings, our development engineers are
systematically working on rising the variety of combos even additional. The
2022 enhancements give our customers a extensive range of sustainable options for
optimizing their machines and methods even more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
