oZafin Posted January 14, 2009 Posted January 14, 2009 Hello Iam really newbie with Inventor 11 and learning work with belt joint. I like to put belt on those two wheels, see attached pic. I get only that kind of error message: "Joint "n°1 :Belt (Rulla:1, Rulla:2)" : no degree of freedom in the model. Joint will be deactivated." Could somebody explain what I do wrong ?
JD Mather Posted January 14, 2009 Posted January 14, 2009 Look at the top of your browser under Grounded and you will see that none of your parts have any degrees of freedom. You need to add Revolution joints to the two wheels (Rulla?).
oZafin Posted January 15, 2009 Author Posted January 15, 2009 Now I "convert assembly constraints" and get wheels ungrounded and two spatial joints. Is that correct now? I could now do belt joint ok but, when I run simulation nothing happens, no error message. I add torgue to leftside wheel (Rulla1) and get that kind of error message "In joint "n°3 :Belt (Rulla:1, Rulla:2)" distance between centers must be fixed." What is problem now?
Hoozin Posted January 15, 2009 Posted January 15, 2009 Yes, only aligned insert. I'm sorry, I misunderstood that previous statement. Though the error now confuses me more.
oZafin Posted January 15, 2009 Author Posted January 15, 2009 Now I get it work. Problem is spatial joints, I change it to revolution joints and it works now.
