Involute Equation

Hi there!! Now I am designing bevel and sun and planetry gear for my university project. I am facing a problem that , the gears which I drawn using CREO 3.0 ( Student Edition), is not mesh properly in the assembly window. Can any one suggest me a valid idea to comeover this problem and also suggest me how to draw ring gear. Thanks in advance.

Waiting a better solution. Also Suggest me the involute equation.

The ring gear should be a "folded rack" and therefore the teeth are straight faced.

All the nominal come from rack profiles.

  ...To the best of my recollection.

Involute - Wikipedia, the free encyclopedia

I would not draw anything but the pitch circles of the gears. There is no value to the calculations available in Creo with regards to the gear teeth unless you are looking to make low quality teeth.

For decent gears, look at gearotic.com for one of the least expensive dedicated high quality gear tools. There are others that are significantly more. They offer academic licensing, so perhaps you can get your school to help.
