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 types. The new merchandise allow users further flexibility in their methods with out dropping the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which provides much more
safety in the drivetrain in many applications. The coupling variant permits customers to
specify a most torque in order that crucial 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 factor, Flender introduces a second new
coupling that ensures frictionally engaged clamping connections. In this case, the
plain, cylindrical machine shaft end is connected to the coupling hub through a clamping
connection without a feather key and service ability is increased. For instance,
assembly or replacement of worn elastomers can be carried out rather more easily.
No connecting machine elements should 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 standard expansion pieces for normed shaft
distances, the DKS is the shortest possible double-cardanic solution for the market.
The shortened general size permits cost-optimized use with a small shaft distance
dimension with out dropping some great benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition
to the beforehand used rubber components manufactured from NBR, Flender now also offers
elastomers manufactured from thermoplastic polyurethane (TPU). Following เพรสเชอร์เกจ4นิ้ว
enhance for all N-Eupex couplings with NBR packings in 2020, the usage of TPU
packings allows the power density to be increased by one other 20 % on
average. For sizes 300 and above, the familiar NBR elastomer is mixed with
cloth inserts and the torque capability is again raised.
“With a view to the long tradition of cam couplings, our growth engineers are
systematically working on growing the number of combinations even additional. เกจวัดแรงดันแก๊ส give our customers a wide range of sustainable options for
optimizing their machines and techniques much more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
