Three new N-Eupex couplings and optimised versatile parts

Flender is increasing the portfolio of its versatile coupling sequence N-Eupex by introducing three new varieties. The new products allow users additional flexibility in their methods with out dropping the compact design and excessive load capacity of a pin coupling.
เกจวัดแรงดันไนโตรเจน -Eupex ERN is equipped with a torque limiter, which provides much more
security in the drivetrain in plenty of applications. The coupling variant permits customers to
specify a most torque in order that critical torques for the motor and output machine
are not transmitted. Machines and techniques are protected against overload and
harm, thus considerably increasing 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 through a clamping
connection with no feather key and repair ability is increased. For example,
meeting or substitute of worn elastomers could be carried out rather 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 kind, which was launched in
2020, addresses the pump market with standard growth pieces for normed shaft
distances, the DKS is the shortest possible double-cardanic solution for the market.
The shortened total length permits 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 spherical off the modular extensions. In addition
to the previously used rubber elements made from NBR, Flender now also presents
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, using TPU
packings allows the facility density to be elevated by one other 20 percent on
average. For sizes 300 and above, the familiar NBR elastomer is mixed with
material inserts and the torque capability is again raised.
“With a view to the long custom of cam couplings, our improvement engineers are
systematically working on rising the variety of combos even further. The
2022 enhancements give our users a variety of sustainable choices for
optimizing their machines and techniques even more and decreasing maintenance,”
explains André Artmann, Head of Coupling Sales.
