Torque limiters & Overrunning clutches

The power needed by the implement machines and the heavy conditions under which drive shafts often work , require the usage of safety devices in order to preserve their integrity.Safety devices improve the performances and reduces the risk of accidents.
BENZI & DI TERLIZZI manufacture a wide range of torque limiters capable of protecting the transmission organs from recurrent power overloads.

Friction disc clutch.
The relative rotation of the friction surface limits the transmitted torque to a preset value. This can be used as a safety device for highinertia machines/implements. The tightening torque can be adjusted by modifying the compression value of the spiralshaped springs.

Shear bolt clutch.
This clutch cuts off power transmission when the torque exceeds the calibration value. The bolt must be replaced with one of equal size and resistance class. The torque limit can be calibrated based on bolt size and position with respect to the rotation axis of the drive shaft.

Automatic cam clutch/cut out clutch.
This clutch cuts off power transmission when the torque exceeds the calibration value. To restore motion, simply reduce the speed (or stop) to automatically obtain reengagement.

Radial pin clutch.
This clutch cuts off power transmission when the torque exceeds the calibration value. It offers the advantage of automatically re-engaging itself when the requested torque value falls below the calibration value. It can be calibrated with increasing torque intervals of 100 Nm.

Overrunning clutch.
The overrunning clutch eliminates power comebacks to the tractor during the deceleration phases. It is recommended for implements with high inertial mass.
