Three new N-Eupex couplings and optimised flexible parts

Flender is increasing the portfolio of its versatile coupling series N-Eupex by introducing three new sorts. The new products enable users additional flexibility of their techniques with out dropping the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which offers even more

safety in the drivetrain in many applications. pressure gauge 10 bar coupling variant allows users to

specify a most torque so that important torques for the motor and output machine

usually are not transmitted. Machines and systems are protected against overload and

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

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

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

connection with no feather key and repair ability is increased. For example,
assembly or alternative of worn elastomers may be carried out rather more simply.
No connecting machine components 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 introduced as a “short

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

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

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

dimension with out shedding the 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 elements manufactured from NBR, Flender now additionally provides

elastomers manufactured from thermoplastic polyurethane (TPU). Following ไดอะแฟรม

improve for all N-Eupex couplings with NBR packings in 2020, the utilization of TPU

packings permits the facility density to be increased by another 20 percent on

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

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

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

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

optimizing their machines and techniques much more and decreasing upkeep,”

explains André Artmann, Head of Coupling Sales.
