Three new N-Eupex couplings and optimised flexible elements

Flender is increasing the portfolio of its flexible coupling collection N-Eupex by introducing three new sorts. The new products allow users additional flexibility of their methods with out dropping the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which provides even more
safety in the drivetrain in many purposes. The coupling variant permits users to
specify a maximum torque so that critical torques for the motor and output machine
are not transmitted. Machines and methods are protected from overload and
harm, 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 finish is connected to the coupling hub via a clamping
connection with no feather key and service ability is increased. For instance,
assembly or alternative of worn elastomers can 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 brand 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 pieces for normed shaft
distances, the DKS is the shortest possible double-cardanic resolution for the market.
The shortened total size allows cost-optimized use with a small shaft distance
dimension without losing 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 provides
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 one other 20 percent on
common. For sizes 300 and above, the familiar NBR elastomer is mixed with
fabric inserts and the torque capability is once more raised.
“With a view to the long custom of cam couplings, our improvement engineers are
systematically engaged on increasing the variety of mixtures even additional. เพรสเชอร์เกจnuovafima give our customers a extensive range of sustainable choices for
optimizing their machines and methods even more and reducing maintenance,”
explains André Artmann, Head of Coupling Sales.
