torque limiting clutch

[ctolbert]

Is there a mechanical device that can torque limit without destroying the gear train and attached motor? I seem to remember a clutch that one could set at a specific value.

Shear pins are currently used. And with the amount of devices; it is a maintenance nightmare. A VFD with torque limiting cannot be employed either.

Imagine a conveyor system feeding a hopper with a very small wet powder that gums up everything and stops the process. The shear pins will snap, unless the system is ran back and forth a few times.

Websites or opinions are greatly appreciated.

I used to work with conveyor and product handling systems and we routinely used mechanical clutches. We used Mayr clutches (already mentioned above) along with Cabat (spelling?) and a few other manufacturers. Your specific application will limit your choices, for instance there were times when we needed an all stainless steel clutch for machinery that would be washed down often (usually we just had a shroud over a cheaper clutch but sometimes this wasn't good enough). The models we used were spring loaded and you could order them for different torque ratings (or buy different springs and change them yourself if you wanted to try a different setting).

For more suppliers than you care about go to

and search on "clutch" or "mechanical clutch".
