Flender is increasing the portfolio of its flexible coupling collection N-Eupex by introducing three new varieties. The new merchandise enable customers further flexibility in their systems with out shedding the compact design and excessive 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 functions. The coupling variant allows customers to
specify a most torque so that critical torques for the motor and output machine
aren’t transmitted. เกวัดแรงดัน and methods are protected against overload and
damage, thus significantly increasing 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 related to the coupling hub through a clamping
connection with no feather key and repair capability is increased. For instance,
assembly or replacement of worn elastomers could be carried out much more simply.
No connecting machine components 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 introduced as a “short
version” into Flender’s modular system. While the DK kind, which was launched in
2020, addresses the pump market with commonplace expansion pieces for normed shaft
distances, the DKS is the shortest possible double-cardanic resolution for the market.
The shortened overall size enables cost-optimized use with a small shaft distance
dimension without shedding the advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition
to the beforehand used rubber elements made of NBR, Flender now also provides
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, the utilization of TPU
packings allows the ability density to be increased by one other 20 % on
average. For sizes 300 and above, the acquainted NBR elastomer is combined with
fabric inserts and the torque capability is once more raised.
“With a view to the lengthy custom of cam couplings, our improvement engineers are
systematically working on growing the variety of mixtures even additional. The
2022 enhancements give our customers a wide range of sustainable options for
optimizing their machines and methods much more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
