Flender is expanding the portfolio of its versatile coupling series N-Eupex by introducing three new varieties. The new merchandise enable users further flexibility in their techniques without losing the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which supplies much more
security within the drivetrain in many functions. The coupling variant allows 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
harm, thus considerably growing system availability.
With the N-Eupex B plus clamping component, 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 and not using a feather key and repair capability is increased. For instance,
assembly or substitute of worn elastomers can be carried out rather more easily.
No connecting machine parts have to be moved, the time required is halved
and so is the downtime of the machine.
With เกรดวัดแรงดัน -Eupex DKS, a brand 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 normal enlargement pieces for normed shaft
distances, the DKS is the shortest potential double-cardanic solution for the market.
The shortened total length allows cost-optimized use with a small shaft distance
dimension with out shedding some great benefits 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 made of NBR, Flender now additionally provides
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings allows the power density to be elevated by one other 20 p.c on
average. For sizes 300 and above, the familiar NBR elastomer is mixed with
material inserts and the torque capability is again raised.
“With a view to the long tradition of cam couplings, our improvement engineers are
systematically engaged on growing the variety of mixtures even further. The
2022 enhancements give our customers a extensive range of sustainable options for
optimizing their machines and systems much more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
