Three new N-Eupex couplings and optimised versatile elements

Flender is expanding the portfolio of its flexible coupling collection N-Eupex by introducing three new sorts. The new products allow customers further flexibility in their systems with out shedding the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which supplies much more

security within the drivetrain in plenty of purposes. The coupling variant allows customers to

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

aren’t transmitted. Machines and techniques are protected from overload and

harm, thus considerably rising 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 by way of a clamping

connection and not using a feather key and repair capacity is increased. For instance,
assembly or replacement of worn elastomers may be carried out much 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 brand new double-cardanic coupling is launched as a “short

version” into Flender’s modular system. While เกจ์วัดความดัน , which was launched in

2020, addresses the pump market with normal enlargement items for normed shaft

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

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

to the beforehand used rubber components manufactured from NBR, Flender now additionally presents

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

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

packings allows the facility density to be increased by one other 20 percent on

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

cloth inserts and the torque capability is again raised.
“With a view to the long tradition of cam couplings, our development engineers are

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

2022 enhancements give our customers a variety of sustainable options for

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

explains André Artmann, Head of Coupling Sales.
