Three new N-Eupex couplings and optimised flexible parts

Flender is increasing the portfolio of its versatile coupling sequence N-Eupex by introducing three new varieties. The new merchandise enable users extra flexibility in their systems without dropping the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which provides much more
security in the drivetrain in many applications. The coupling variant permits customers to
specify a most torque so that crucial torques for the motor and output machine
are not transmitted. Machines and techniques are protected from overload and
harm, thus considerably increasing system availability.
With เกจวัดแรงลม -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 linked to the coupling hub by way of a clamping
connection with no feather key and service capacity is elevated. For instance,
meeting or substitute of worn elastomers could 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 launched 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 potential double-cardanic solution for the market.
The shortened total size allows cost-optimized use with a small shaft distance
dimension with out dropping the advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition
to the beforehand used rubber components manufactured from NBR, Flender now additionally offers
elastomers made from thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, the usage of TPU
packings permits the power 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 long custom of cam couplings, our growth engineers are
systematically working on growing the number of combos even additional. The
2022 enhancements give our users a variety of sustainable options for
optimizing their machines and techniques much more and reducing maintenance,”
explains André Artmann, Head of Coupling Sales.
