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: Scientists present new observations to understand the phase transition in quantum chromodynamics

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.

Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...

Im Focus: Patented nanostructure for solar cells: Rough optics, smooth surface

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.

"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...

Im Focus: New soft coral species discovered in Panama

A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.

Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
