Three new N-Eupex couplings and optimised flexible parts

ไดอะแฟรม is expanding the portfolio of its flexible coupling sequence N-Eupex by introducing three new sorts. The new products allow users further flexibility in their techniques with out shedding the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which offers much more

safety in the drivetrain in lots of functions. The coupling variant allows customers to

specify a maximum torque in order that important torques for the motor and output machine

aren’t transmitted. Machines and methods are protected against overload and

injury, thus significantly increasing system availability.
With the N-Eupex B plus clamping factor, Flender introduces a second new

coupling that ensures frictionally engaged clamping connections. In เพรสเชอร์เกจ , the

plain, cylindrical machine shaft end is connected to the coupling hub through a clamping

connection with no feather key and service ability is elevated. For instance,
assembly or replacement of worn elastomers could be carried out rather more simply.
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 kind, which was launched in

2020, addresses the pump market with normal growth items for normed shaft

distances, the DKS is the shortest potential double-cardanic answer for the market.
The shortened overall length allows cost-optimized use with a small shaft distance

dimension with out shedding the advantages 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 made from NBR, Flender now also provides

elastomers manufactured 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 ability density to be elevated by another 20 percent on

common. For sizes 300 and above, the familiar NBR elastomer is combined with

fabric inserts and the torque capacity is once more raised.
“With a view to the lengthy custom of cam couplings, our growth engineers are

systematically working on increasing the variety of mixtures even additional. The

2022 enhancements give our customers a variety of sustainable options for

optimizing their machines and systems much more and lowering upkeep,”

explains André Artmann, Head of Coupling Sales.
