Three new N-Eupex couplings and optimised versatile components

Flender is increasing the portfolio of its flexible coupling sequence N-Eupex by introducing three new varieties. The new products permit customers additional flexibility in their systems with out shedding the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which offers much more
security within the drivetrain in many functions. The coupling variant allows customers to
specify a most torque so that important torques for the motor and output machine
aren’t transmitted. Machines and methods are shielded from overload and
harm, thus significantly growing 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 linked to the coupling hub via a clamping
connection without a feather key and service ability is elevated. For instance,
meeting or alternative of worn elastomers may be carried out much 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 type, which was launched in
2020, addresses the pump market with standard growth items for normed shaft
distances, the DKS is the shortest attainable double-cardanic resolution for the market.
The shortened general size enables 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 เกจแรงดันลม
to the previously used rubber parts manufactured from NBR, Flender now additionally presents
elastomers made of thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings permits the facility density to be elevated by one other 20 percent on
common. For sizes 300 and above, the familiar NBR elastomer is mixed with
material inserts and the torque capacity is once more raised.
“With a view to the long tradition of cam couplings, our improvement engineers are
systematically engaged on rising the variety of combos even additional. The
2022 enhancements give our users a variety of sustainable options for
optimizing their machines and systems even more and reducing maintenance,”
explains André Artmann, Head of Coupling Sales.
