I don’t see any part models for the sprockets or track segments available. Can we get some kind of a mechanical drawing or something, even if it’s only a 2D print, with basic dimensions so it’s possible to block up a concept in CAD with a higher percentage of fact than guess work? I can make solid (or is it surface?) models in Rhino if I have the basic OD and centerline kind of details.
I’d like to look at doing something with the larger sprockets and wider track segments but I have no way to figure out how many segments or what kind of spacing is needed between the sprockets.
Looked right over it, sorry. So are the wider tracks the same length just a higher number of sections? Basically I am asking if I can just break apart the 2" model and step and repeat the sections to a 3" width?
Can we get a drawing or something? We can probably guesstimate the diameter based on the “Sprocket diameter with tracks is 3.75” on the product page. The width though, and here is my thought, if two back-to-back sprockets are the correct width for 2" tracks then you would need a 1" spacer between them for the 3" tracks? Is it that simple?
That will work, or you can use them as is but they will not be “centered” on the track. If I can’t get anything from my injection molder I do have some files, but they are less than perfectly accurate.
I think I’m all set. I gave the solidworks model in the library to one of the ME guys here and in discussing the problem he showed me a few ways to manuipulate it that I had not thought of. Rhino doesn’t have as many automatic things as he was using on solidworks but just understanding the geometry of thing was enough to get the gears turning in my head. No pun intended.
Has anybody noticed yet that the 2intrack.3dm track segment in the cad library is a mirror image from an actual track segment? It probably doesn’t matter I suppose, except I am working on a sprocket model from a 2-d .dwg and I happened to notice this as I was staring at the parts in hand and trying to reconcile against what was on the screen. If I hold a real part up to the screen the joints are staggered in reverse.
