Three new N-Eupex couplings and optimised flexible parts

Flender is increasing the portfolio of its versatile coupling collection N-Eupex by introducing three new types. The new merchandise permit customers extra flexibility in their methods with out shedding the compact design and excessive load capacity of a pin coupling.
เกจวัดแรงดัน -Eupex ERN is supplied with a torque limiter, which provides even more

safety within the drivetrain in lots of applications. The coupling variant permits users to

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

are not transmitted. Machines and systems are shielded from overload and

harm, thus considerably rising system availability.
With digital pressure gauge -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 finish is related to the coupling hub via a clamping

connection with no feather key and repair capacity is increased. For instance,
assembly or substitute of worn elastomers can be carried out far more easily.
No connecting machine components 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 expansion items for normed shaft

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

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

to the previously used rubber parts made of NBR, Flender now additionally offers

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

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

packings allows the facility density to be elevated by another 20 p.c on

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

fabric inserts and the torque capacity is again raised.
“With a view to the long 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 variety of sustainable choices for

optimizing their machines and techniques even more and reducing upkeep,”

explains André Artmann, Head of Coupling Sales.
