Limiting high torques reliably

In addition to numerous other innovations, mayr® power transmission is to present a large disengaging torque limiting clutch for torques of up to 280,000 Nm at the Hannover Trade Fair. This large clutch for heavy engineering is combined with curved tooth couplings for the connection of two shafts.

Disengaging EAS®-element clutches for heavy engineering disengage the input and output on overload. The energy from the rotating masses stored in the system can slow down freely.

As international market leaders, mayr® power transmission has provided the widest product range of load holding, load disconnecting, torque and force limiting, frictionally locking, positive locking, magnetic, regulatable and switchable torque limiting clutches for decades.

In spite of this wide range, the company have noticed an increasing demand for new torque limiting clutches with extremely high torques and for application-optimised solutions. For this reason, the performance range of the disengaging EAS®-element clutches has been extended at the time of the Hannover Trade Fair in 2011. The latest design with curved tooth couplings for the connection of two shafts is designed for torques of up to 280,000 Nm.

EAS®-element clutches transfer the torque using positive locking during normal operation. On overload, they separate the input and output nearly residual torque-free with a high switch-off and repeat accuracy. The kinetic energy from the rotating masses stored in the system can slow down freely. Such disengaging clutches do not automatically re-engage. They remain disengaged until they are re-engaged either manually or via mechanical or hydraulic devices.

For 30 years, disengaging EAS®-element clutches have been protecting systems and drives in heavy engineering against expensive overload damage. Our decades of experience and the collective, comprehensive know-how make mayr® power transmission your ideal partner for mechanical overload protection in drives with extremely high torques, high speeds and large mass moments of inertia.

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...
