Three new N-Eupex couplings and optimised flexible components

Flender is increasing the portfolio of its versatile coupling series N-Eupex by introducing three new sorts. The new merchandise allow customers further flexibility in their techniques with out dropping the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which provides much more

safety within the drivetrain in many purposes. The coupling variant allows users to

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

usually are not transmitted. diaphragm seal and systems are protected from overload and

harm, thus significantly growing system availability.
With diaphragm seal -Eupex B plus clamping element, Flender introduces a second new

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

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

connection with no feather key and service ability is increased. For example,
meeting or alternative of worn elastomers could be carried out rather more easily.
No connecting machine elements have to 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 introduced as a “short

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

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

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

dimension with out dropping some great benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition

to the previously used rubber parts manufactured from NBR, Flender now additionally presents

elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque

improve for all N-Eupex couplings with NBR packings in 2020, using TPU

packings allows the power density to be increased by another 20 p.c on

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

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

systematically engaged on rising the variety of combos even additional. The

2022 enhancements give our customers a wide range of sustainable options for

optimizing their machines and methods even more and decreasing upkeep,”

explains André Artmann, Head of Coupling Sales.
