In harsh operating and environmental conditions such as dust, dirt, splash water, heat or cold, especially in heavy machinery construction, the drive trains are often encapsulated and therefore difficult to access. But these machines also need reliable overload protection. That is why Mayr Antriebstechnik has developed the EAS-reverse, a robust, unlocking safety clutch that is designed to withstand the high loads as well as to automatically snap back into place - ideal for drives without access to re-engagement.

Separation without residual torque in the event of overload

With EAS-reverse, all functional processes can be automated via the drive alone. In the event of an overload, when the torque exceeds the value set on the clutch, a patented disengagement mechanism should separate the input and output in fractions of a second with almost no residual torque and with high switch-off and repeat accuracy. The kinetic energy of the rotating masses stored in the system can flow freely. The clutch copes with long drive down times after it has responded. By slowly turning backwards, the EAS reverse safety clutch automatically engages again without the use of pneumatics or hydraulics.

Simple and flexible

According to Mayr power transmission, the safety clutch transmits the torque with very little play (<0.05 °) and has hardened functional parts. It is easy to use and has numerous variants and additional features. For example, the combination with an elastomer coupling enables simple disconnection of the drive train by loosening a few screws without having to move the engine or transmission. In addition, the combination with a brake disc on the output side can also be implemented for applications with load-holding output. The EAS-reverse can also be integrated in a solid housing with standard IEC or NEMA dimensions. It is therefore protected against dust and splash water, adverse environmental conditions cannot harm the coupling.After the new safety coupling with the first three sizes previously covered a torque range from 80 Nm to 2500 Nm, now there is the expansion by a fourth size up to 5000 Nm and a bore diameter up to 100 mm.
