Heavy-duty machines are used in the field of steel production, where heat and dirt are part of everyday ambient conditions. For this reason, the drive lines of the machines in the steel plants are frequently encapsulated and therefore hard to access. Mayr has developed the EAS-reverse a robust, disengaging torque limiter which can withstand both high loads and which automatically re-engages – which is ideal for drives without access possibilities for re-engagement.
Re-engagement through reverse rotation
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.
