In contrast, torque limiters employing permanent magnets that couple loads through magnetic flux have no friction material to wear or produce debris.
Available sealed units contain the wear debris. Debris generated by friction material in open, dry designs make them unsuitable for certain environments such as in clean rooms. Friction-style torque limiters, dry or wet, wear over time and may need maintenance or eventual replacement. Friction-plate torque limiter image via Bondioli & Pavesi Though torque limiters differ from clutches in that they can’t or shouldn’t continuously throttle mechanical transmission, some temporarily slipping limiters (especially those based on friction plates) are referred to as slip or overload clutches. Generally, higher-capacity units that dissipate more energy (or those designed to continuously slip) use oil cooling to maintain friction material at safe operating temperatures. Pneumatic and hydraulic actuated torque limiters may also use friction material to transmit torque but rely on pistons or diaphragms moved by air or fluid pressure to force friction surfaces together and adjust torque limits.įriction material may be dry or in an oil bath. Exceeding a set torque level causes the surfaces to slip relative to one another, limiting power transmission. A spring-actuated frictional torque limiter applies spring force to opposing friction surfaces on input and output hubs. Friction torque limitersįriction torque limiters slip in response to an overload event and fully engage other times. They come in three basic types: friction, ball detent, and shear pin. Torque limiters span a wide range of rated torque - from much less than 1 N-m to over 10,000 kN-m. Torque limiters are indispensable on bottle-capping machines. A machine that installs bottle caps, for example, must apply sufficient torque to tighten a cap but not break the bottle. They also serve in equipment needing specific torque levels. Torque limiters actuate on the order of milliseconds to prevent overload, shock, and torque spikes that could otherwise damage components or shorten operating life.
