Three new N-Eupex couplings and optimised flexible parts

Flender is increasing the portfolio of its flexible coupling collection N-Eupex by introducing three new varieties. The new merchandise enable users further flexibility of their techniques with out dropping the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which offers much more

safety within the drivetrain in plenty of applications. The coupling variant allows customers to

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

are not transmitted. Machines and methods are protected against overload and

damage, thus significantly rising system availability.
With the N-Eupex B plus clamping component, Flender introduces a second new

coupling that ensures frictionally engaged clamping connections. In this case, the

plain, cylindrical machine shaft finish is connected to the coupling hub via a clamping

connection and not utilizing a feather key and repair ability is increased. For instance,
meeting or replacement of worn elastomers can be carried out far more easily.
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 model new double-cardanic coupling is introduced as a “short

version” into Flender’s modular system. While the DK type, which was launched in

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

distances, the DKS is the shortest possible double-cardanic answer for the market.
เกจวัดแรงดันดิจิตอล shortened total length enables cost-optimized use with a small shaft distance

dimension with out losing some nice 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 elements made from 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, using TPU

packings allows the power density to be elevated by another 20 % on

average. For sizes 300 and above, the acquainted NBR elastomer is mixed with

material inserts and the torque capability is again raised.
“With a view to the lengthy tradition of cam couplings, our improvement engineers are

systematically working on increasing the variety of combos even further. The

2022 enhancements give our customers a variety of sustainable choices for

optimizing their machines and systems even more and reducing maintenance,”

explains André Artmann, Head of Coupling Sales.
