Couplings - Torque Limiting Couplings

Protect mechanical equipment, or its work, from damage from mechanical overload. These torque limiters are designed for machines with chain, gear or belt drives to prevent overloading of sensitive motors, gearboxes and machine components. If overloading causes the level of transmitted torque to exceed the frictional torque between the two friction discs, which is created by the pretensioned disc spring, the coupling slips and forcibly breaks the connection between the driving and driven side. When the torque subsequently falls to a level below that of the frictional force, the friction discs re-engage and torque transmission without backlash resumes.
