Three new N-Eupex couplings and optimised flexible elements

Flender is expanding the portfolio of its flexible coupling collection N-Eupex by introducing three new varieties. The new merchandise allow users further flexibility in their methods without shedding the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which provides even more

security within the drivetrain in many applications. The coupling variant allows customers to

specify a most torque in order that crucial torques for the motor and output machine

usually are not transmitted. Machines and methods are protected from overload and

injury, thus considerably 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 linked to the coupling hub through a clamping

connection with no feather key and repair capacity is increased. For instance,
meeting or replacement of worn elastomers can be carried out much more simply.
No connecting machine elements 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 type, which was launched in

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

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

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

to the beforehand used rubber elements made of NBR, Flender now additionally presents

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

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

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

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

material inserts and the torque capability is once more raised.
“With a view to the long tradition 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 methods much more and decreasing upkeep,”

explains André Artmann, Head of Coupling Sales.
