Three new N-Eupex couplings and optimised flexible components

Flender is expanding the portfolio of its flexible coupling series N-Eupex by introducing three new varieties. The new products allow users further flexibility in their techniques without losing the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which supplies much more

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

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

aren’t transmitted. Machines and methods are shielded from overload and

damage, thus significantly growing 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 finish is related to the coupling hub through a clamping

connection with no feather key and service ability is increased. For example,
meeting or replacement of worn elastomers may be carried out far 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 model 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 standard expansion items for normed shaft

distances, the DKS is the shortest potential double-cardanic answer for the market.
The shortened general length allows 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 round off the modular extensions. In addition

to the beforehand used rubber elements manufactured from NBR, Flender now also presents

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

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

packings permits the ability density to be elevated by another 20 percent on

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

fabric inserts and the torque capacity is again raised.
“With pressure gauge 0 10 bar ราคา to the lengthy tradition of cam couplings, our development engineers are

systematically working on increasing the variety of combinations even further. The

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

optimizing their machines and systems even more and lowering maintenance,”

explains André Artmann, Head of Coupling Sales.
