Flender is increasing the portfolio of its flexible coupling series N-Eupex by introducing three new sorts. The new products allow users additional flexibility of their methods without dropping the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which offers even more
security within the drivetrain in many functions. The coupling variant permits customers to
specify a maximum torque so that crucial torques for the motor and output machine
aren’t transmitted. Machines and methods are protected from overload and
damage, thus significantly rising 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 finish is related to the coupling hub via a clamping
connection and not using a feather key and service capacity is elevated. For instance,
meeting or substitute of worn elastomers could be carried out much more easily.
No connecting machine parts should 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 introduced 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 items for normed shaft
distances, the DKS is the shortest attainable double-cardanic resolution for the market.
The shortened general length allows cost-optimized use with a small shaft distance
dimension without dropping 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 elements manufactured from NBR, Flender now also presents
elastomers made of thermoplastic polyurethane (TPU). Following diaphragm seal for all N-Eupex couplings with NBR packings in 2020, the usage of TPU
packings allows the facility density to be increased by one other 20 p.c on
average. For sizes 300 and above, the acquainted NBR elastomer is mixed with
material inserts and the torque capacity is once more raised.
“With ไดอะแฟรม ซีล to the lengthy tradition of cam couplings, our growth engineers are
systematically engaged on increasing the variety of combos even additional. The
2022 enhancements give our users a wide range of sustainable choices for
optimizing their machines and methods much more and decreasing upkeep,”
explains André Artmann, Head of Coupling Sales.
