Flender is expanding the portfolio of its versatile coupling series N-Eupex by introducing three new sorts. The new products allow users extra flexibility of their systems with out dropping 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 many applications. The coupling variant allows customers to
specify a most torque in order that critical torques for the motor and output machine
aren’t transmitted. Machines and methods are protected from overload and
harm, thus considerably rising 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 linked to the coupling hub via a clamping
connection without a feather key and service ability is increased. For instance,
meeting or substitute of worn elastomers could be carried out rather more simply.
No connecting machine components 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 introduced as a “short
version” into Flender’s modular system. While the DK kind, which was launched in
2020, addresses the pump market with standard expansion pieces for normed shaft
distances, the DKS is the shortest attainable double-cardanic answer for the market.
The shortened general size allows cost-optimized use with a small shaft distance
dimension without losing the advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In เกจแรงดันสูง
to the previously used rubber parts manufactured from NBR, Flender now also presents
elastomers manufactured 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 mixed with
fabric inserts and the torque capability is again raised.
“With a view to the long tradition of cam couplings, our development engineers are
systematically working on growing the number of combinations even further. The
2022 enhancements give our customers a variety of sustainable choices for
optimizing their machines and methods much more and reducing maintenance,”
explains André Artmann, Head of Coupling Sales.
