Serrated Teeth imbedment in steel

Serrated Teeth imbedment in steel

Serrated Teeth imbedment in steel

(OP)
Working on a dynamic safety device with serrated teeth. Looking for design or test information on serrated teeth imbedment into steel.

RE: Serrated Teeth imbedment in steel

Imbedment? hmmm, how do you plan on imbedding them? Normally, things are not imbedded, they are welded and/or bolted to steel. Will the teeth be cutting anything or are they ratchet stops?

We need a bit more information.

RE: Serrated Teeth imbedment in steel

(OP)
The application for the safety device is to stop a free fall of a vertical traveling platform. The safety device is a mechanical backup system and is replaced after one use. The safety device is a rotating cam with serrated teeth. In a free fall the cam teeth rotate onto a W-section flange. The hardened teeth "imbed" and lock onto the flange. Thru testing we have established a cam load limit. I'm look for information to understand the dynamics and limits for a redesign of the cam teeth.

RE: Serrated Teeth imbedment in steel

You might try re-posting your message in the mechanical engineer's forum. I can't say that I have any experience in designing something to rip INTO structural steel. I usually spend my time trying to prevent that sort of thing. BTW, I sure hope that the I beam gets replaced also. If not, let me know the address of the building in which your putting this elevator. I'd like to avoid it. :)

You might also see if their is an elevator association. They should have info on safety devices.
