Constructed for easy installation - New shaft couplings for high torques of up to 110,000 Nm

12.08.2011
High screw tightening torques can prove a real challenge when installing large shaft couplings, in particular in restricted space conditions. For this reason, new ROBA®-DS disk pack coupling construction sizes have been equipped with an easy to install, positive locking connection which works at very low tightening torques.

mayr® power transmission has extended the scope of performance on the tried and tested ROBA®-DS disk pack couplings. The new construction sizes cover a nominal torque range from 22,000 to 110,000 Nm. In these sizes, the flexible disk pack is connected via positive locking and backlash-free with the mounted parts.


Far less screw tightening torque is required for the positive locking cone connection of the new ROBA®-DS disk pack couplings in comparison to frictionally locking constructions.

A new cone connection means that the screw tightening torques can be reduced to a fraction of their original value in comparison with standard frictionally locking constructions. This makes installation and de-installation substantially easier. In addition, the units for installation and de-installation of the coupling cannot be displaced.

On large couplings, the ease of installation is also an important economic aspect. Simple and quick installation can save many hours of work and unnecessary costs. Apart from that, handling large couplings is a back-breaking job. Why should things be made more difficult for fitters than necessary?
ROBA®-DS disk pack couplings are extremely robust, are not sensitive to high and low temperatures and are extremely torsionally rigid and maintenance-free. They transmit the torque backlash-free and without wear and compensate for shaft misalignment. On double-jointed couplings, the component between the two disk packs can be varied very flexibly in length for adjustment to the shaft distance. Due to their superb characteristics, disk pack couplings are frequently the preferred choice if high torques are to be transferred.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
