For original equipment manufacturers investment costs, life-cycle costs, power-to-weight ratio, fitness for use and cost of purchasing couplings are in the focus of their considerations.
By the introduction of the new N-ARPEX all-steel multi-disk coupling FLENDER Mechanical Drives is continuing the success story of the proven ARPEX series of couplings. N-ARPEX is the consistent further-development of the ARPEX into what is at present the best-performing coupling in the market – a leap in performance that in this size was possible only by a number of design measures. A round-up:
Lower costs through higher performance
An optimised disk-pack and a revised component design enable transmission of very high torques and speeds.
Low bearing loads through low weight
A marked increase in bore capacities with standard hubs increases performance capability and lowers the N-ARPEX’s weight.
Highest fitness for use also through maximum flexibility
Its suitability for use at low-temperatures between -50 and 280 °C and its high displacement capacities up to 1° enable the N-ARPEX to be used for many different purposes in special conditions.
Easy selection and reduction in storage costs
The bundling of the ARPEX ARS, ARC and ARP series together to make a single series results in a reduction in complexity from 42 to 14 couplings. So storage costs are reduced. Choosing the desired coupling is made very much easier.
With our all-steel couplings the reliable transmission of torque between the shafts to be connected is backlash-free, torsionally rigid and flexurally elastic. So displacement can be compensated for in an axial, angular and radial direction. Our multi-disk couplings are not prone to wear and are maintenance-free.
The couplings and clutches have been designed for use in potentially explosive environments as defined in Directive 2014/34/EU and comply with the requirements in standards API610/ISO 13709 and API671/ISO 10441.
