I have a gear and rack setup and am trying to mate the two so I can see the rotation of my pinion when I move the rack. Any ideas??? Thanks

Could be done with an equation relating the mating distance of the rack from a given datum to the angle of pinion. Probably would work for only one rev of pinion, however.

dear

thr is no posibility of doing this kinda mate in SW 2006 but i had done that, u may require sum other work out 2 do that

but in SW 2007 i feel they have added this feature

You may be out of luck. To the best of my knowledge, Solidworks lacks the specific ability to mate curved faces of that nature. I'm fairly sure its impossible to see the motion you want as an explicit outcome of your defined geometry.

That being said, there is a specific "Gear Mate" in the advanced mate drop down. All this does is cause one shaft to rotate relative to another at a constant rate that the user inputs. This mate doesn't rely on the geometry of the gears themselves, so its pretty much useless if you're trying to check your geometry. But is can provide a usefull illustration of the "assumed" relative motion. I've never tried to use it with a rack and pinion setup,and it may not work. But I think its you're only shot.

You are right about the geometry mate. You can input the ratio regardless of size or number of teeth. I guess it is more for illustration (eye candy) and to keep track of the rotation of other gears as in a transmission.
As far as a rack and pinion, I don't think you can gear mate this by definition of the mate. I did it by creating a huge dia gear so over the length of the rack I was interested in the diameter was nearly flat. I had to create a ratio to enter of some very large number. It was just trial an error but it gave the visualization.
