Flender is expanding the portfolio of its flexible coupling sequence N-Eupex by introducing three new sorts. The new products permit customers further flexibility in their techniques with out shedding the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which provides even more
safety within the drivetrain in many purposes. The coupling variant allows customers to
specify a most torque so that crucial torques for the motor and output machine
are not transmitted. Machines and systems are protected against overload and
harm, thus considerably increasing 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 finish is linked to the coupling hub through a clamping
connection with no feather key and repair capacity is elevated. For Prize ,
assembly or replacement of worn elastomers could be carried out rather more easily.
No connecting machine parts should 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 type, which was launched in
2020, addresses the pump market with standard enlargement pieces for normed shaft
distances, the DKS is the shortest attainable double-cardanic answer for the market.
The shortened overall size enables cost-optimized use with a small shaft distance
dimension with out shedding the benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition
to the beforehand used rubber components manufactured from NBR, Flender now additionally offers
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, using TPU
packings allows 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
cloth inserts and the torque capability is once more raised.
“With a view to the long tradition of cam couplings, our improvement engineers are
systematically engaged on increasing the number of combinations even further. The
2022 enhancements give our customers a variety of sustainable choices for
optimizing their machines and methods even more and reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
