Planetary Gear Ratio
Planetary Gear Ratio
(OP)
I have a micro-motor I am trying to install a planetary gear system on. My outside diameter is 1.65". My motor spins at around 1200RPM and I want to reduce it to 220-250RPM. The sun gear is the drive and the planets are held in position and the ring gear is my output drive. Does anyone know what gears I would use and teeth count, pitch, etc.?

The center distance would be 0.44" with Diametral pitch of 50.
You would need some profile shift on the sun to avoid undercut.

A star for you. Your 14t/30t/73t gearset even assembles!
