Torque limiters with a working principle based on the joint action of friction rings and the pressure exercised by the springs.
When the overload torque value is reached the transmission unit (crown for chain transmission, toothed pulley, etc.), placed between the two friction rings, starts to slide thus stopping its rotation and consequently the action of the machine.
It is particularly suitable in dusty environments, it engages silently and without vibration and both directions of rotation are protected.
