Steel industry Reliable protection for heavy load applications

From iron ore to finished steel

In the field of heavy load applications, such as in the steel industry – from iron ore mining to steel rolling mills – mayr® power transmission stands for future-orientated solutions with high performance density as well as high torques and speeds. Where stones burst, hot steel steams and heavy loads have to be held and braked, only robust, resistant and sturdily-dimensioned clutches and brakes can cope with the extreme conditions. In the drive line, they guarantee a secure connection between the shafts, ensure permanently reliable overload protection and can, in case of emergency, absorb peak loads with extremely high friction work: The clutches and brakes by mayr® power transmission ensure maximum operational safety and productivity in the large systems.

Perfect overload protection for drives which are hard to access

In case of adverse operating and ambient conditions due to dust, contamination, spray water, heat or cold, drive lines are frequently encapsulated and therefore hard to access, especially in the heavy machine industry. In order to protect such drives and machines reliably against overload, mayr® power transmission has developed a disengaging torque limiter with the EAS®-reverse on which all functional processes can be carried out automatically via the drive alone.

In case of overload, a patented disengagement mechanism disconnects the input and output without residual torque. This permits long run-out times. The EAS®-reverse re-engages automatically simply by rotating backwards slowly, without the need for pneumatics or hydraulics – ideal for drives which cannot be accessed for re-engagement.

  • Residual torque-free disconnection in case of overload
  • Automatic re-engagement through reversal of direction of rotation
  • Easy handling
  • Long run-out times permitted
  • Robust double bearing
  • Steplessly adjustable torque
  • Extremely low backlash (< 0.05°)
  • Hardened functional components
  • Housing with standard IEC or NEMA dimensions
  • Temperature range from -30 °C to +80 °C
