HOW TO MAKE PARTS "PUSH" EACH OTHER?

matthew_saenz

So for a school project, I have to make a geneva drive. For those of you who don't know what a Geneva drive is, this link demonstrates it pretty well: http://benbrandt22.github.io/genevaGen/ 
My drive has 4 positions, an a drive crank radius of 2, a b drive crank radius of 2, a pin diameter of .5 and an allowed clearance of .05. So I was wondering how to use onshape mates to make the desired motion occur. 
Thanks

@ matthew_saenz , I have tried Geneva mechanism.i m not able to give 360 deg rotation to the wheel since i m given tangent constrain.i m able to rotate only 90 deg.


How can i make it working.. any one...? here is the document..

As Neil stated in the other thread, Onshape currently does not support intermittent contact of mates, and therefore this type of mechanism unfortunately is not possible. Please feel free to submit an improvement request if you would like to see this functionality.
