Re: Making Gears
Im still reading the book on the design accelorator and cannot completely use it yet so for the time being this is what i do:
make a circle to the diameter of the gear and extrude it. I then draw two lines that are dimensioned at an angle of say 360/24/2/2. This would be for 24 teeth. draw a "V" and set the bottom to the depth of each tooth, and then extrude the cut. revolve by the number of teeth. Lastly, for constraint animations, i draw another circle SLIGHTLY smaller on top and extrude it to flatten the tips of the teeth to a similarly sized circle.
The math works itself out quite easily and your left with gear that may be easily constrained to an animation as the computer can find the gear ratio when assembling the product itself since the egdes of the teeth act resemble a similarly sized circle.
I just started the fisher price motor. Its shown below, and is only about halfway done and some resizing needs to be done, but it animates VERY well.
