Three new N-Eupex couplings and optimised versatile elements

Flender is expanding the portfolio of its versatile coupling collection N-Eupex by introducing three new types. The new merchandise permit users further flexibility in their techniques without dropping the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which provides even more
security in the drivetrain in many applications. The coupling variant allows 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 growing system availability.
With the N-Eupex B plus clamping component, Flender introduces a second new
coupling that ensures frictionally engaged clamping connections. In เพรสเชอร์เกจไฮดรอลิค , the
plain, cylindrical machine shaft end is connected to the coupling hub through a clamping
connection and not using a feather key and service capability is increased. For instance,
assembly or alternative of worn elastomers may be carried out far more simply.
No connecting machine parts have to 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 kind, which was launched in
2020, addresses the pump market with commonplace growth items for normed shaft
distances, the DKS is the shortest possible double-cardanic resolution for the market.
The shortened total length allows cost-optimized use with a small shaft distance
dimension with out losing some great benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition
to the previously used rubber parts made from NBR, Flender now additionally provides
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, the utilization of TPU
packings allows the facility density to be elevated by another 20 p.c on
common. For sizes 300 and above, the familiar NBR elastomer is mixed with
fabric inserts and the torque capability is again raised.
“With a view to the long custom of cam couplings, our improvement engineers are
systematically engaged on increasing the variety of combinations even additional. The
2022 enhancements give our customers a extensive range of sustainable options for
optimizing their machines and techniques even more and decreasing maintenance,”
explains André Artmann, Head of Coupling Sales.
