Planetary Gearset #1 (Sun Gear Pitch Diamerer + Planet Gear Pitch Diameter) Must be equal to: Planetary Gearset #2 (Sun Gear Pitch Diamerer + Planet Gear Pitch Diameter)

Use the following equation to align the planets from the two planetary gearsets with one another:

When modeling the gears the most important design constraint is keeping the planets from each gearset at the same center to center distance. Once you have decided on a number of planets and your two planetary gear combinations that you would like to use you need to model the gears, You will need to go off into your CAD program. Keep in mind that those two equations will not prevent you from making planet gears that overlap, heres a quick tool for that: (Whole Number) for both Planetary Gearsets (No_of_teeth_sun + No_of_teeth_Ring) / Number_of_planets. Teeth_Sun + (Teeth_Planets*2) = Teeth_Ring_GearДЇor figuring if the planets (pinions) can perfectly evenly spaced: You will need to study the gear tooth combinations that work properly in a planetary gearset, keep in mind that not every combination of gears will fit together, and not every combination that fits together will allow for evenly spaced planets (and that IS necessary), to find gear combinations that fit these two design requirements, use these two equations.ДЇor Figuring Gear Combinations that fit together: I am experimenting with newer designs with 20 deg pressure angle and they're very promising.

Gears with a lower pressure angle have much less friction, and last longer, but aren't as strong.

using gears with lots of teeth can achieve very high gear ratios(500:1+), and higher ratios than i have designed have been achieved by others, such as Emmet.

The more planets, the harder it is to meet all the constraints.

The following design constraints are very important: You will need two planetary gear sets, the closer the number of teeth, the higher the output gear ratio will be. If you would like to design a gearbox like this to integrate into your own project, just follow these somewhat complicated and poorly written instructions. When you use the 4th module you should re-use Sun Gear #2 to space out the planet gears within Module #4 The use of Ring Gear #4 and the 4 Module Planet Gears is optional and used to increase the amount of torque this gearbox can transfer, as well as to decrease the amount of (radial?) load on each gear, think of it like a door hinge. The other important thing to realize here is that Ring Gears #1 & #3 will be at the same potential and Ring Gears #2 & (Optional #4) will be at the same potential

Now, When the Planet Gears make a full 360 Degree rotation around the Sun Gears, Ring Gear #2 ( and the Optional Ring Gear #4) will move 27.7 Degrees, ( 2 Teeth) When you rotate Sun Gear #1 (The sun Gear with the D-Shaft hole) The Planet gears orbit that gear causing Sun Gear #3 to rotate at the exact same speed as Sun Gear #1 I designed this gearbox for my Modular Robot Arm Project, check it out! :Д«oth models are 100% compatible with this gearbox (& the 66.46:1 gearbox) and each otherДЄssembly -ДЄlign the planet gears in order as shown in the main picture, insert a sun gear, Snap Ring Gear #1 on, Inset all sun Gears, snap the other 2 or 3 ring gears on, also, you will need to close the gap in the rings before you spin this gearset or else it could skip teeth and get out of alignment, for this i have included the ring closures, that fits over all the ringsДЇor any instructions i may have missed, please refer to this :, this gearbox is very similar in concept.

Using the one piece sun is a good upgrade for this as it cuts down on backlash. if your using the 4th module you may choose to use the #2 sun gear in module 4 in conjunction with this. Fixed this issue with One Piece sun V2.Дў/27/17- I designed a one piece sun gear for this, one version with a large drive gear on it and one version with a 5mm D shaft hole, the one piece sun gear is compatible with the 3 & 4 module planet gears. 4/27/17-Made another version of this with a higher gear ratio, they are 100% compatibleД¤/14/17- The D-Shaft Hole was not perfectly centered on the one piece sun.
