Three new N-Eupex couplings and optimised flexible components

Flender is increasing the portfolio of its flexible coupling sequence N-Eupex by introducing three new types. The new products allow customers additional flexibility of their methods with out dropping the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which provides much more

safety in the drivetrain in plenty of applications. The coupling variant permits customers to

specify a maximum torque so that critical torques for the motor and output machine

aren't transmitted. Machines and systems are protected against overload and

harm, thus significantly growing 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 end is related to the coupling hub by way of a clamping

connection with no feather key and service capacity is elevated. For instance,
meeting or substitute of worn elastomers could be carried out much 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 brand new double-cardanic coupling is launched as a “short

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

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

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

dimension with out losing some nice benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In เกจวัดแรงดันน้ำมันเบนซิน

to the previously used rubber elements made of NBR, Flender now also offers

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

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

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

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

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

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

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

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

explains André Artmann, Head of Coupling Sales.
