Three new N-Eupex couplings and optimised versatile components

Flender is expanding the portfolio of its versatile coupling collection N-Eupex by introducing three new varieties. The new products permit users further flexibility in their methods with out losing the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which provides even more

safety within the drivetrain in many functions. เกจวัดแรงดัน coupling variant permits customers to

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

usually are not transmitted. Machines and systems are protected against overload and

injury, thus considerably increasing 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 linked to the coupling hub through a clamping

connection with no feather key and service capacity is increased. For instance,
meeting or alternative of worn elastomers can be carried out much more easily.
No connecting machine parts 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 the DK kind, which was launched in

2020, addresses the pump market with normal expansion pieces for normed shaft

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

dimension without dropping the benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition

to the previously used rubber components made from NBR, Flender now also offers

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

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

packings permits the power density to be elevated by one other 20 percent on

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

fabric inserts and the torque capability is again raised.
“With pressure gauge 10 bar to the long custom of cam couplings, our growth engineers are

systematically engaged on rising the variety of combinations even further. The

2022 enhancements give our customers a variety of sustainable choices for

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

explains André Artmann, Head of Coupling Sales.
