Housed torque limiter features automatic re-engagement

In case of rough operating and ambient conditions such as dust, dirt, water spray, heat or cold, the drive lines, particularly in heavy mechanical engineering, are frequently encapsulated and therefore hard to access. But these machines in particular require reliable overload protection. Therefore, mayr power transmission has now developed with the EAS-reverse a robust, disengaging torque limiter that can withstand both high loads and which automatically re-engages - which is useful for drives for which there is no access for re-engagement.

On the EAS-reverse torque limiter, all functional processes can be automated via the drive alone. In case of overload, if the torque exceeds the value set on the clutch, a patented disengagement mechanism separates the input and output almost residual torque-free with high switch-off and repetitive accuracy. The kinetic energy from the rotating masses stored in the system can slow down freely. After responding, the clutch can withstand long drive run-out times. Through slow reverse rotation, the EAS-reverse torque limiter re-engages automatically without the use of pneumatics or hydraulics.

The new EAS-reverse torque limiter from mayr power transmission transmits the torque with exceptionally low wear (

mayr's EAS-reverse can also easily be integrated into a solid housing with standard IEC or NEMA dimensions. It is therefore protected against dust and water spray, and resistant to adverse ambient conditions. The new torque limiter already covers the first three construction sizes with a torque range from 80-2500Nm, and this range is now to be extended with a fourth size up to 5000Nm and a bore diameter of up to 100mm. The EAS-reverse provides permanent protection for machines and protects them reliably against overload damage, thereby ensuring operational safety and maximum productivity.
