Three new N-Eupex couplings and optimised versatile parts

Flender is increasing the portfolio of its flexible coupling collection N-Eupex by introducing three new sorts. The new merchandise enable customers extra flexibility of their methods 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 supplies even more
security in the drivetrain in plenty of functions. The coupling variant permits customers to
specify a maximum torque in order that crucial torques for the motor and output machine
aren’t transmitted. Machines and methods are protected against overload and
injury, 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 via a clamping
connection without a feather key and repair capacity is increased. For instance,
assembly or substitute of worn elastomers could be carried out rather more easily.
No connecting machine elements 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 launched as a “short
version” into Flender’s modular system. While the DK sort, which was launched in
2020, addresses the pump market with normal expansion items for normed shaft
distances, the DKS is the shortest attainable double-cardanic resolution for the market.
The shortened overall length permits cost-optimized use with a small shaft distance
dimension without dropping the advantages 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 manufactured from NBR, Flender now additionally presents
elastomers made from thermoplastic polyurethane (TPU). Following เกจวัดแรงดันลมราคา
improve for all N-Eupex couplings with NBR packings in 2020, using TPU
packings permits the ability density to be increased by one other 20 percent on
average. For sizes 300 and above, the acquainted NBR elastomer is mixed with
cloth 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 growing the number of combinations even further. The
2022 enhancements give our customers a wide range of sustainable choices for
optimizing their machines and methods much more and decreasing upkeep,”
explains André Artmann, Head of Coupling Sales.
