# How To Calculate Gear Teeth From Gear Ratio

### How To Calculate Gear Ratio - HBReducer

We can express this basic concept with the formula Gear ratio = T2/T1, where T1 is the number of teeth on the first gear and T2 is the number of teeth on the second. Method 1 of 2: Finding the Gear Ratio of a Gear Train Two Gears. 1. Start with a two-gear train. More Information

### Gear terminology and teeth calculation formulas easy guide ...

### Developing the Gear Ratio Formula

The order of the two numbers in a ratio is very important. In this case, the ratio of the 15-tooth driver gear and the 45-tooth driven gear is 3:1. A gear ratio is always given as the ratio of the rotations of the driver gear to the rotations of the driven gear. In terms of the bicycle example the students used earlier, the gear ratio is the ratio of pedal rotations to wheel rotations. More Information

### How to calculate gear teeth from given gear ratio, torque ...

You Can find gear ratio if you have known number of teeth in the gears. (N1/N2)=(Z2/Z1) N1 and N2 are speed of gears. Z1 and Z2 are number of teeth. In case of finding gear ratio in Transmission the number of gears will not be known for that. 1.A initial marking should be done at … More Information

### Ring and Pinion Ratio Calculator (By Number of Teeth)

You should be able to find your gear ratio listed on the axle tag, however, if that has gone missing, you can simply count the number of teeth on each gear and divide the number of ring gear teeth by the number of pinion gear teeth. [ Ring Gear Teeth / Pinion Gear Teeth ] = [ 41 / 11 ] = [ 3.73 ] Popular OEM and Aftermarket Gear Ratios More Information

### Working out the number of Teeth from Gear Ratios | Gears ...

The sums N1+N2 and NG1+NP1 hast to be equal (module is same) Calculate multiple values of 2,25 and 4,2, since the teeth numbers are integers. The first common multiple value for both 2,25 and 4,2 is the sum of the teeth N. Therefore NP1 is 15 and NG1 63-15=48. More Information

### What is Gear ratio? [How to calculate Gear Ratio with Formula]

This ratio can be expressed as the number of gear teeth divided by the number of pinion teeth. So in this example, since there are 54 teeth on the larger gear and 18 teeth on pinion. There’s a ratio of 54 to 18 or 3 to 1 this means that pinion is turning at three times the speed of the gear. More Information

### Gear ratios and compound gear ratios

For example, for the gear at left the blue gears are 7 and 21 teeth, while the green gears are 9 and 30 teeth. Thus, the first gear ratio is 7:21 and the second is 9:30. Multiplying the two together gives (7x9):(21x30) = 63 : 630, which is 1:10. More Information

### How to calculate gear teeth from given gear ratio, torque ...

From the Torque you need to design the gear for strength. The designed out parameters are the minimum centre distance, module and face width. Pressure angle determines the minimum number of teeth on the pinion. The pinion is normally the gear for ... More Information

### Ring and Pinion Ratio Calculator (By Number of Teeth)

For example, a 3.73 gear ratio requires 3.73 driveshaft rotations to turn your tires once around. You should be able to find your gear ratio listed on the axle tag, however, if that has gone missing, you can simply count the number of teeth on each gear and divide the number of ring gear teeth by the number of pinion gear teeth. More Information

### Gear ratios and compound gear ratios

Gear ratios and compound gear ratios. Working out simple gear ratios (two gears) A feature often requested in my gear program is that it should calculate and display the gear ratio.. The reason it does not have this feature is that the gear ratio is also the tooth count ratio (of the two gears), and that is a value that the user has to enter. More Information

### Planetary gear ratio calculations

Planetary gear ratio calculations This article also available in Spanish. A question that I often get is how to work out planetary gears using the gear template generator Working out the tooth counts for planetary gears is actually not that complicated, so I initially neglected to mention how to do it.

### Gear Ratio Calculator| Spicer Parts

The calculation uses the number of teeth in the ring gear and divides it by the number of teeth in the pinion gear to provide you with a “ [result] to 1” ratio. For example, if the pinion gear has 41 teeth, and the ring gear has 11 teeth, the ratio would be calculated as 41/11, which is equal to 3.73 = 3.73:1. More Information
