Three new N-Eupex couplings and optimised flexible elements

Flender is increasing the portfolio of its versatile coupling collection N-Eupex by introducing three new sorts. The new products allow users additional flexibility in their techniques with out shedding the compact design and excessive load capability of a pin coupling.
เพรสเชอร์เกจ -Eupex ERN is supplied with a torque limiter, which supplies even more

safety in the drivetrain in many purposes. The coupling variant permits customers to

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

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

injury, 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 end is linked to the coupling hub through a clamping

connection without a feather key and repair capacity is increased. For instance,
assembly or substitute of worn elastomers can be carried out rather more easily.
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 new double-cardanic coupling is introduced as a “short

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

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

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

dimension without 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 of thermoplastic polyurethane (TPU). Following the torque

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

packings permits the power density to be elevated by one other 20 p.c on

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

cloth inserts and the torque capacity is again raised.
“With a view to the lengthy custom of cam couplings, our growth engineers are

systematically engaged on increasing the number of mixtures even additional. The

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

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

explains André Artmann, Head of Coupling Sales.
