Jointing a Geneva Mechanism Help Please

I have created a Geneva Mechanism (as part of a series of Mechanisms for my students to model for a BTEC CAD assignment) but I am struggling to get the two cogs to rotate correctly when the handle pin engages with the slot. I have tried a number of joint options but to no success. Either the slotted wheel does not rotate correctly, or the drive wheel just ends up locked. Can anyone advise please. See Power point picture

Hi @hjacksonHFWA5 

@Great question. If the design is 100% correct, creating a Contact Set should work.
Please attach the .f3d file and we can take a look at it.

Thanks,

Hi @hjacksonHFWA5 

I found a Geneva gear model from one of my previous books. Open the attached .f3d file and you can see that I was able to get the mechanism to work using a Contact set.

 

Please let me know if you have any questions.

Hi @hjacksonHFWA5 

Glad to help. One suggestion. When creating the Contact Set, only add components that will need to interact with each other. This will help performance.

Please keep us posted on your success.
