RPM Based Variable Offset for Valve Trains Etc

This is something a lot of people have talked about making. This uses a helical gear and RPMs to move a sliding "gear" ( you can also run an actual gear for this if you want, but the rollers work well for the first draft) along the helical gear to achieve an offset.

It can be compressed for those who want to use it for their engines and there are a few ways to make it. I modeled this off the MIVEC valve train running in the 6G72 engine in my car.

1,2,3 to change speeds, they each toggle so you press them in order.

The spring causes it to bounce some, but with a load it wont do that as much. The sharper you make the helical gear, the less it will try to function as a worm drive.

Enjoy!
