Also included: a planetary ratio calculator, gear coupler for finding available gear combinations at given axle spacing and Gearcyclopaedia featuring detailed info on 38 types of gears. Assuming that the red gear is the input, the gray beam is the output and that the yellow gear is not rotating (e. 12/08/2007 2:49 PM. Here is the possible way

This calculator helps generating these possible gear configurations while calculating turn ratios in different scenarios: when ring gear is fixed, 

a) Planetary Type In this type, the internal gear is fixed. The input is the sun gear and the output is carrier D. The transmission ratio is calculated as in 

Depending on the choices, the resulting gear ratio can be overdrive, reduction, or reverse reduction. Three community members submitted

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

Epicylic Gears - Ratio Calculation. Purpose of Calculation - To calculate the ratios of various epicylic gear arra

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.

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

Count the number of sun gear teeth and the number of ring gear teeth if the planetary gear is set in underdrive with the carrier as the output. Add the two numbers together. Divide the resulting number by the number of teeth on the driving member for the gear in underdrive when the carrier is the output. Planetary Gear Train Ratio.

6/13 · We can calculate ratio transmission by formula: i = -A/C -> reduce speed system. If ring gear is input power -> Output is sun gear. : i = -C/A -> increase speed system. + We will fix sun gear, planet gear can rotate around their axis. If carrier is input power -> Output is ring gear. i

Solution: Using Formula 3 above and solving for Tc yields: A fixed ring gear means Tr=0. If Nr=65 and Ns=26 then we get: 

Number of Planets. Solve for: Sun Gear, Planets and Carrier, Ring Gear. Sun Teeth. Planet Teeth. Ring Teeth. Sun Speed. Carrier Speed. Ring Speed.

Calulate Gear ratios for the planetary gear of the type 'Split Ring Planetary Gear'. They are mainly used for huge gear ratio reductions for stepper motors 

In our example, the intermediate gear ratios are 20/7 = 2.9 and 30/20 = 1.5. Note that neither of these are equal to the gear ratio for the entire train, 4.3. However, note also that (20/7) × (30/20) = 4.3. In general, the intermediate gear ratios of a gear train will

The number of teeth for the planets won't alter the gear ratios, as long as all connections (the planet parts) use the same number of teeth. For the 'Split Ring Planetary Gear' we have:

Number of teeth on 1st driving gear Number of teeth on 2nd driving gear (or enter 1) Number of teeth on 1st driven gear Number of teeth on 2nd driven gear (or enter 1) Gears Speed of first gear Speed of last gear Speed of planet carrier arm Input Output Stationary Planet carrier Sun Generic Ring Type A (sun, planets on carrier, ring) Train ratio e

Ring ÷ pinion= A xle ratio (this will only change if you use under/over drive gears) Gear ratio (pinion/spur under the dust cover) x T rans ratio (2.60 stock) = T otal transmission ratio. Total transmission ratio x axle ratio (2.92 stock) = Final drivetrain gear ratio. If everything is stock an easier way to find your final drive ratio is. 16h ago

To make calculating planetary gear ratios as simple as possible, note the number of teeth on the sun and ring gears.Next, add the two numbers together: The sum of the two gears' teeth equals the number of teeth on the planetary gears connected to the carrier. a gear calculation for the planet gear set, instead of just calculations for gear pairs.

You may require a calculator to determine the final ratio. First Steps To make calculating planetary gear ratios as simple as possible, note the number of teeth on the sun and ring gears. Next, add the two numbers together: The sum of the two gears' teeth equals the number of teeth on the planetary gears connected to the carrier.

For the planetary transmission, a calculation of gear module for bevel gears is first performed, For calculating the transmission ratio from the diagram.
