Three new N-Eupex couplings and optimised flexible elements

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.
