Adam Eriksson Posted April 12 Report Share Posted April 12 I am currently working on a mechanical flower where I will use a linear motion to create a radial motion from 0 to 90 degrees. The linear motion will be 40mm from a crankshaft and I am now having problems designing the rack and pinion. Is there any easy way to calculate or think about how the degrees and distances should be between the gears? I have done some research but have not found an easy way to calculate it and I would like some input on my current design. Right now I have the problem that the further the pinion moves upwards the more problems I get (see pictures). I would highly appreciate any help with this problem! Thanks in advance.

DrD Posted April 16 Report Share Posted April 16 Looks to me like you need to study the theory of involute gearing a bit more before jumping into this problem. Your CAD drawings show straight-sided teeth on both the gear and the rack, but that is not how it should work. Dig into gear theory first!
