Besides the "EAS-HSC", the "EAS-HSE" (High-Speed Elements) now transmits significantly higher speeds – as a special version, even up to 20,000 rpm. This clutch with a disengaging mechanism is therefore suitable for operation in all test stands which require large clutches.
The EAS-HSE series is based on the tried and tested design principles of the "EAS-Elements".
The EAS-HSE series is based the design principles of the "EAS-Elements", which have proven their worth over decades, and has been designed for the extreme demands set by test stand technology in high torque ranges. For large clutches with high torques, the clutch specialist applies several overload elements across as large a diameter as possible.
As a result, significantly higher torques are realisable than with a central disengaging mechanism. In the standard version, speed values of up to 12,000 rpm are permitted; in a special version even up to 20,000 rpm.
The separation of input and output occurs almost residual torque-free with high switch-off and repetitive accuracies. Due to the axial stroke of the bolt or ball carrier, the control segments move radially outwards, thereby disconnecting the components axially. The elements do not re-engage automatically, but instead remain separated until they are re-engaged manually, or using a device. The position for synchronous re-engagement to maintain balance quality is clearly marked on the clutch.
As a result, the EAS-HSE provides a reliable and precise torque limitation, and, thanks to the complete separation of the drive line, does not cause engagement impacts. The basic prerequisite for use of a torque limiting clutch in high-speed applications is, among other things, the high balance quality of every individual component in order to achieve optimum running smoothness of the drive line in combination with the other components. The clutches have an extremely compact design and permit a low-backlash high performance density. Furthermore, the reduction of the rotating masses has a positive effect on the running smoothness and the machine dynamics.
Three sizes for torques from 100 to 8400 Nm have been realised in the EAS-HSE series up until now. Depending on their size, they are permitted for speedvalues from 6000 to 12,000 rpm. Four further sizes are planned. The complete series will in future cover torques of up to 25,000 Nm and speeds of up to 16.000 rpm. Due to their characteristics, the new torque limiting clutches of the EAS-HSE series are not only suitable for test stands, but also for all other high-speed drive axes.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
