Description

Planetary Gears Calculator calculate the gear teeth and gear speed of planetary gears system.
Plus quickly simulate how the Planetary Gears works on the fly.

This is a great tool, especially for DIYer who want to design their own Planetary Gears System quick and easy.
Preview how these systems work before 3D print own planetary gear system.


Formula for Planetary gear systems:
Sun Teeth = ringTeeth - 2 * planetTeeth
Planet Teeth = (ringTeeth - sunTeeth) / 2
Ring Teeth = sunTeeth + 2 * planetTeeth

ST = sunTeeth
PT = planetTeeth
RT = ringTeeth
SunSpeed = (ST+RT)/ST * PlanetCarrierSpeed - RT/ST * RingSpeed
PlanetCarrierSpeed = RT/(ST+RT) * RingSpeed + ST/(ST+RT) * SunSpeed
RingSpeed = (ST+RT)/RT * PlanetCarrierSpeed - ST/RT * SunSpeed


Planetary gear systems, also known as epicyclic gear systems, are important components in modern engineering.

Planetary gear systems are useful for speed variation and commonly found from automatic car transmissions and industrial food mixers to operating tables and solar arrays.

There are four core components that make up the planetary gear systems, the ring gear, the sun gear and the planetary gears connected to the carrier.

Gears can’t be noted with negative #’s

This gear is losing atomic structure and will collapse like before we expanded and noted it correctly with the math. If you code using a minus or possibility of one then this is poor code. Never ask for nothing. Expect something, every second, penny, ray, light , sound and mirror moment counts and has substance. Use an ~> arrow instead of a - or if logic still allows negatives then go through these simple proofs 1 +is always positive, where one goes it will always equal one. One degree, one person, one atom etc if moved will be 1 when it arrives whether in accounts receivable, accounts payable or below zero degrees, 108 becomes 109 when it arrives but how could 109 lose one if 1 is moved of course. Math books show minus but shops, suns, humans and wolves know that it’s not the computers fault we didn’t book very well, killed trillions of semis and all of the sky but in real life there isn’t a minus only a move. Even nothing doesn’t go below zero because there he doesn’t exist and neither do instructions, life or love, below zero some things are noted because they get cold there but those are degrees and not accounting. They are permanent markers that could have been done better if anyone knew how cold it could be but we didn’t. The fact we fix this and below sea level should tell you how destructive to health, growth, money or friends subtracting or dividing yourself can be. When others do it try to correct them until all are sick of it then repeat. It is too important. In 3 days the Sun would break because the nicest lady has a bad code. The depression would be felt around the Universe! Don’t be a breaker be a light that shines always as you were intended to be!
