:ROFLMAO: I couldn't sell anyone here on putting explosive pins into the design I am working on (not a safety belt). I guess the need for a pretensioner has to be legit and not just for engineers to have fun playing with :LOL:
^ That one seems to be a somewhat different mechanism.
I thought about the spring idea, but the original video states that the orange piece is not affix and is "free to move".
But then I found this video which shows the same mechanism as the OP, but the actual mechanism, not an animation.
Hello,
I am having difficulty understanding part of the seat belt mechanism design shown at 3:21 on the following video:
The piece shown in orange appears to float coaxially to the spool shaft until it is accelerated, where it then is pulled off axis, rotating about the pivot point, so that...
The machine I'm working on is an enclosed/sealed environment... only 1.1 atm.... but sealed nonetheless. This would affect placing a relief hole on the dowel pin hole.
The real question was about difficulty of insertion of the pin if there is no path through which the air from the pin hole can...
I have a machine design featuring steel dowel locating pins and diamond points pressed into blind holes in :
steel castings
aluminum casting
steel machined parts
aluminum machined parts
Someone suggested that we should be using vented pins to make insertion easier;
Our company's standard...
Hello,
Is is possible to control the value of a dimension or parameter between one simplified rep of a given part and another simplified rep of that same part?
We used to do this with family tables, but our company doesn't use family tables.
Thanks,
Glenn
Unfortunately I did not get the error to clear.
I've attached a sample part.
Thank you,
Glenn

I got the model working.
What it needed as part of the pattern group was a Datum Plane through the point, normal to the axis, and normal to the default front plane. This datum plane gave each of the tooth an absolute direction dictated by the front/back of the Datum plane rather than the...
Attached is an example timing belt which is automatically generated as a configured Creo file by Stock Drive Components. Their stable and reliable models use a similar methodology to what I have tried. Other than being generated in an older version of Creo, I'm not sure what they're doing...
I've created a timing belt path.
Established a pattern consisting of equally groups equally spaced. Each group contains a points and an an axis through that group and normal to the belt inside surface. I adjusted the display on the axis so that the axis points inward.
I then created a belt...
