Three new N-Eupex couplings and optimised flexible parts

Flender is increasing the portfolio of its versatile coupling sequence N-Eupex by introducing three new types. The new merchandise allow users further flexibility of their techniques without dropping the compact design and high load capability of a pin coupling.
ความหมายของเครื่องวัดความดัน -Eupex ERN is equipped with a torque limiter, which provides even more
safety in the drivetrain in plenty of applications. The coupling variant allows users to
specify a maximum torque so that important torques for the motor and output machine
are not transmitted. Machines and methods are shielded from overload and
damage, thus significantly rising 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 linked to the coupling hub through a clamping
connection with no feather key and repair capability is increased. For instance,
assembly or alternative of worn elastomers could be carried out far more simply.
No connecting machine elements have to be moved, the time required is halved
and so is the downtime of the machine.
With the N-Eupex DKS, a model new double-cardanic coupling is launched as a “short
version” into Flender’s modular system. While the DK kind, which was launched in
2020, addresses the pump market with normal enlargement items for normed shaft
distances, the DKS is the shortest possible double-cardanic solution for the market.
The shortened overall size allows 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 spherical off the modular extensions. In addition
to the beforehand used rubber components made from NBR, Flender now also provides
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, the usage of TPU
packings allows the ability density to be increased by another 20 p.c on
average. For sizes 300 and above, the acquainted NBR elastomer is mixed with
material inserts and the torque capability is again raised.
“With a view to the lengthy tradition of cam couplings, our improvement engineers are
systematically working on growing the number of combinations even additional. The
2022 enhancements give our customers a variety of sustainable choices for
optimizing their machines and methods much more and decreasing maintenance,”
explains André Artmann, Head of Coupling Sales.
