Planetary gearing consists of three elements: a sun gear , a ring gear and a number of planet gears mounted on a carrier. One of these elements is always fixed, one is an input and one is an output. Select gear sizes below and hit CALCULATE to see ratios for

GEAR RATIO CALCULATOR. Read off your mph at any rpm in any gear. Enter transmission and rear tyre data in the yellow boxes. Tyre diameter is automatically calculated from tyre profile info e.g. 195/55 x 15 = 24.44 inch tyre diameter. This chart is particularly useful when used in conjunction with an engine's power and torque data - showing.

R = 2 × P + S That is to say, the number of teeth in the ring gear is equal to the number of teeth in the middle sun gear plus twice the number of teeth in the planet gears. In the gear at left, this would be 30 = 2 × 9 + 12 This can be made more clear by imagining "gears" that just roll (no teeth), and imagine an even number of planet gears.

The planet gears act as idlers and do not affect the gear ratio. The planetary gear ratio equals the sum of the number of teeth on the sun and ring gear divided by the number of teeth on the sun gear. For example, a planetary set with a 12-tooth sun gear and 72-tooth ring gear has a gear ratio of 7:1 ([12 + 72]/12 = 7). Planetary gear sets can.

1/9 · The gear ratio formula for two meshing gears is simple and intuitive, while the gear ratio formula for the planetary mechanism is not. In this tutorial, we

Abstract It has been said that deriving the formulas for the ratios between the various gears of an epicyclic planetary gear system is non-intuitive and "taxes the human intellect" To say the least. Internet searches for "How to" proved fruitless and dare I say information is being withheld, so this programmer set out to de-mystify the methods for calculating the widely used equations of.

The ZAR5 planetary gearing calculation program calculates the geometry and strength of sun, planet and ring gear (spur or helical, involute teeth) according
