I have an assembly that includes a Gear Pair connection defined in the Mechanism Application. The models of the gear components themselves are adjustable based on a few input parameters like tooth count, and module etc.
However, if I change the tooth count of either of the gears, I have to manually re-input the new gear ratio in the assembly model. I'm looking for a way to relate the gear ratio in the assembly to these same component parameters, but I cannot find the name of the variable to use for this gear ratio.
How do I find the names of the dimension/parameters in a GearPair connection?
Thank you,
To the best of my knowledge, most of the mechanism "stuff", including gears, cannot be controlled outside of the interface where they are created. See https://community.ptc.com/t5/Creo-Parametric-Ideas/Mechanism-Set-Gear-Pitch-Circle-via-Parameter-or-Relations/idi-p/456363
Hmmm, that's frustrating; especially since there are parameters for more obscure variables in other types of connections. In the relations window under Local Parameters, if I filter by Current and all sublevels, I can see parameters for kinetic friction and restitution of each of the joints. Even the coefficients of servomotor profiles can be found here. But sadly, I see no such parameter for gear ratio.
I checked the same as you and came up with the same lack of results. No parameters accessible for the gear connections. This software should be called "Creo (mostly)Parametric"
