Flender is expanding the portfolio of its versatile coupling series N-Eupex by introducing three new types. The new products enable users extra flexibility of their techniques without shedding the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which provides even more
security in the drivetrain in many functions. 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 systems are protected against overload and
damage, thus considerably increasing 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 with no feather key and repair ability is increased. For instance,
assembly or substitute of worn elastomers could be carried out rather 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 model new double-cardanic coupling is launched as a “short
version” into Flender’s modular system. While the DK type, which was launched in
2020, addresses the pump market with commonplace enlargement items for normed shaft
distances, the DKS is the shortest attainable double-cardanic resolution for the market.
The shortened general length enables 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 round off the modular extensions. In addition
to the beforehand used rubber components manufactured from NBR, Flender now additionally provides
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, the utilization of TPU
packings permits the ability density to be elevated by one other 20 p.c on
average. For sizes 300 and above, the familiar NBR elastomer is mixed with
fabric inserts and the torque capacity is once more raised.
“With ไดอะแฟรม ซีล to the lengthy tradition of cam couplings, our improvement engineers are
systematically working on increasing the number of mixtures even further. เกจวัดแรงดัน give our customers a broad range of sustainable choices for
optimizing their machines and techniques much more and reducing maintenance,”
explains André Artmann, Head of Coupling Sales.
