Gear Design

Do you go have a machinery's handbook?

Yes, I have few machinery handbooks, but all give details about only symmetrical (circular) shape gears

Shape is not important.

Have you searched for "oval gear design"?

The shape doesn't matter very much. Tooth design, pitch, etc. are far more important.

Like the man said, Machinery's Handbook.

Or, there are plenty of sources, if you just search for them.

Try Gear Mates in SolidWorks....

Thanks,

I will try that

The gear in that pic appears to be circular; does Gear Mates actually do other shapes?

I think so, although I've never tried, It does work for a rack and pinion. The basis for the gear mate is maintaining a tangent relationship along the pitch line. Tomorrow I'll try it for an elliptical gear and pinion.

That could be interesting. I once made a set of elliptical gears for a math class illustration. They were imprecise, with backlash, but they adequately illustrated a gear system with about a 4:1 variable ratio.

Getting a headache now, I think my noodles got caught in one of those gears.

Step back and put some pants on then.

'nuff said.
