Three new N-Eupex couplings and optimised flexible parts

Flender is increasing the portfolio of its flexible coupling sequence N-Eupex by introducing three new types. The new merchandise enable customers further flexibility of their systems without shedding the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which supplies even more
safety in the drivetrain in many purposes. The coupling variant permits customers to
specify a most torque in order that critical torques for the motor and output machine
usually are not transmitted. Machines and systems are shielded from overload and
injury, thus considerably rising system availability.
With the N-Eupex B plus clamping component, Flender introduces a second new
coupling that ensures frictionally engaged clamping connections. In เกจวัดแรงดันpcp , the
plain, cylindrical machine shaft finish is related to the coupling hub by way of a clamping
connection without a feather key and repair capability is elevated. For instance,
assembly or alternative of worn elastomers may be carried out much more simply.
No connecting machine parts must 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 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 items for normed shaft
distances, the DKS is the shortest possible double-cardanic resolution for the market.
The shortened overall length allows cost-optimized use with a small shaft distance
dimension with out dropping the advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition
to the previously used rubber components made of NBR, Flender now additionally presents
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 permits the facility density to be elevated by one other 20 % on
common. For sizes 300 and above, the familiar NBR elastomer is combined with
cloth inserts and the torque capacity is again raised.
“With a view to the lengthy tradition of cam couplings, our development engineers are
systematically working on increasing the number of combinations even additional. The
2022 enhancements give our users a wide range of sustainable options for
optimizing their machines and methods much more and decreasing maintenance,”
explains André Artmann, Head of Coupling Sales.
