Pneumatic clutches are friction clutches with pneumatic control. They allow you to adjust the amount of transmitted torque by changing the air pressure in the cylinder, allow local and remote smooth on/off, and compensate for significant shaft displacements. They have high elastic and damping properties. Without significant design changes, these clutches can be used as brakes, as well as overload limiters.
These couplings are used in drilling rigs, excavators, earthmoving machines, forging equipment, conveyors, mine hoists, etc.
