juansg Posted December 11, 2010 Share Posted December 11, 2010 (edited) Hi Everybody! I'm a newbie with Autodesk Inventor who has a problem trying to animate a gear reducer for a project at college. I've already made the system and it moves ok with the mouse. However, when I enter in Studio and animate the first shaft, I cannot get the rest of the components to move. I've been hours and hours trying to figure the problem out both in the program and on the web, with zero luck. I hope someone can help here. I attached all files (one with assembly, the other one with parts) in case it helps http://www.acro3d.com/reductora.zip thank you very much in advance Edited December 11, 2010 by juansg Quote Link to comment Share on other sites More sharing options...
kencaz Posted December 11, 2010 Share Posted December 11, 2010 Don't try to animate a single shaft as it wont work. You'll need to animate constraints. You say you can move the assembly with your mouse... Are you grabbing one of the gears to do this? (most likely). If that is the case you need to add and drive an angular constraint to rotate a single gear and the rest will follow. BTW, you forgot to add some sub assemblies in your attachment.

juansg Posted December 11, 2010 Author Share Posted December 11, 2010 Oh, sorry about that. I save the complete package here: http://www.acro3d.com/reductora.zip Meanwhile I'll look at that angular constraint (and yes, I am grabbing one of the gears.)

juansg Posted December 11, 2010 Author Share Posted December 11, 2010 oks, I've been able to apply an angle constraint to a gear and drive it for some turns. However, I yet cannot figure out how to drive it in studio Quote Link to comment Share on other sites More sharing options...
kencaz Posted December 12, 2010 Share Posted December 12, 2010 What I did was first add an angular constraint to the pinon gear: Then a rotational constraint for the bearing: (you'll want it to spin a little slower): And then animated the angular constraint and driving the assembly: Ken Quote Link to comment Share on other sites More sharing options...
Be_cool Posted December 13, 2010 Share Posted December 13, 2010 Can anyone explain more closely what should i do with constrains to make gears move like on the picture above...When I create pair of gears with spur gear tool, gears are fixed and they can't move. Should i create gears separately and ater that make an assembly with constrains or... Quote Link to comment Share on other sites More sharing options...
kencaz Posted December 14, 2010 Share Posted December 14, 2010 Should i create gears separately and ater that make an assembly with constrains or... That's what I would do... Ground your shaft and use an insert or mate constraint so that the gears spin freely. Add a rotational constraint so one gear moves opposite the other, then add your angular constraint on one gear using an axis or plane. Then drive the angle constraint.

JD Mather Posted December 17, 2010 Share Posted December 17, 2010 When I create pair of gears with spur gear tool, gears are fixed and they can't move. . When created as a sub-assembly within an assembly (usual practice), right click on the sub-assembly node in the browser and select Flexible.
