Gear simulation engineering software

[renyyz]

hi all. i have an assignment to design a gear system. so, anyone can suggest me a software that i can make a simulation about a gear? prefer simple software that got a lot of function. thank~~

Edit: i tried this software http://gears-simulator.software.informer.com/3.0/
but i need a function to increase the length of gear where it didn't have in this software (or maybe i didn't found it)
btw, sorry for my bad english.

I'm sorry you are not generating any responses at the moment. Is there any additional information you can share with us? Any new findings?

What kind of gearing system? IMO, unless you're designing tooth profiles, there's not really much to designing gearing systems (even planetary gears aren't that hard to look at on paper).
