Three new N-Eupex couplings and optimised flexible elements

Flender is expanding the portfolio of its versatile coupling sequence N-Eupex by introducing three new sorts. The new products enable users further flexibility in their techniques with out shedding the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which offers even more
security in the drivetrain in many applications. The coupling variant allows users to
specify a most torque so that important torques for the motor and output machine
aren’t transmitted. เกจวัดอาร์กอน and techniques are protected from overload and
harm, thus significantly growing 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 connected to the coupling hub through a clamping
connection and not utilizing a feather key and service capability is increased. For example,
meeting or replacement of worn elastomers may be carried out far more easily.
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 standard expansion items for normed shaft
distances, the DKS is the shortest potential double-cardanic answer for the market.
The shortened general length allows cost-optimized use with a small shaft distance
dimension with out losing 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 offers
elastomers made from thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings allows the facility density to be elevated by one other 20 percent on
average. For sizes 300 and above, the familiar NBR elastomer is mixed with
material inserts and the torque capacity is once more raised.
“With a view to the lengthy tradition of cam couplings, our growth engineers are
systematically engaged on increasing the number of combos even further. The
2022 enhancements give our users a broad range of sustainable options for
optimizing their machines and methods even more and reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
