Limiting high torques reliably

12.08.2011
New torque limiting clutch for heavy engineering

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: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
