Three new N-Eupex couplings and optimised flexible elements

Flender is increasing the portfolio of its versatile coupling collection N-Eupex by introducing three new varieties. The new products allow customers additional flexibility in their systems with out shedding the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which provides much more
security in the drivetrain in plenty of functions. The coupling variant permits customers to
specify a maximum torque in order that critical torques for the motor and output machine
aren’t transmitted. Machines and systems are protected from overload and
harm, thus considerably growing system availability.
With the N-Eupex B plus clamping factor, 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 via a clamping
connection with no feather key and repair ability is increased. For instance,
assembly or alternative of worn elastomers could be carried out far more simply.
เกจวัดแรงดันออกซิเจน 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 new double-cardanic coupling is launched as a “short
version” into Flender’s modular system. While the DK sort, which was launched in
2020, addresses the pump market with normal expansion items for normed shaft
distances, the DKS is the shortest potential double-cardanic resolution for the market.
The shortened general size permits cost-optimized use with a small shaft distance
dimension with out losing the advantages 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 manufactured from NBR, Flender now also presents
elastomers manufactured 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 facility density to be increased by another 20 p.c on
average. For sizes 300 and above, the acquainted NBR elastomer is combined with
fabric inserts and the torque capability is again raised.
“With a view to the long custom of cam couplings, our growth engineers are
systematically working on growing the number of combinations even further. The
2022 enhancements give our customers a variety of sustainable options for
optimizing their machines and systems much more and decreasing maintenance,”
explains André Artmann, Head of Coupling Sales.
