KTR Engineering Services Manager, Chris Scholz took a moment to speak with Coupling Tips.com about the make-up of frictionally engaged torque limiters.
“A frictionally engaged torque limiter is one of the more basic styles of torque limiter, one of the oldest styles. It uses a couple of friction disks that compress a plate, a sprocket, or some other primary driver together. It’s basically like brake pads on your car, in reverse; it’s holding the unit in place until the torque is overcome, and then it frictionally disengages, so the pads are held tight based on a threaded spring set system. Once there’s a catastrophic failure, or torque overload, then that torque limiter will slip.
Common applications include electric motor to gear box; we’ll put the torque limiter between there to protect the gear box. We also see these types of torque limiters in pulley systems, where we will integrate the torque limiter onto a shaft, and then integrate a pulley, or sprocket, into the torque limiter to run chain systems to drive conveyors, and other types of manufacturing equipment. That’s typical. “
