Gear Ratio Calculation Formula
The following formula is used to calculate the gear ratio from your sprocket teeth count:
Gear Ratio = Rear Sprocket Teeth / Front Sprocket Teeth
Variables:
- Gear Ratio is the ratio of the number of teeth on the rear sprocket to the number of teeth on the front sprocket.
To calculate the gear ratio, divide the number of teeth on the rear sprocket by the number of teeth on the front sprocket.
What is Gear Ratio Calculation?
Gear ratio calculation refers to the process of determining the ratio between the number of teeth on two gears or sprockets. This ratio is crucial for understanding the mechanical advantage and performance of a vehicle or machine. Proper gear ratio calculation helps in optimizing the performance of vehicles, ensuring efficient power transmission and speed control.
How to Calculate Gear Ratio?
The following steps outline how to calculate the gear ratio using the given formula:
- First, determine the number of teeth on the front and rear sprockets.
- Next, use the formula: Gear Ratio = Rear Sprocket Teeth / Front Sprocket Teeth.
- Calculate the gear ratio by plugging in the values.
- Check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge:
Front Sprocket Teeth = 15
Rear Sprocket Teeth = 45
Gear Ratio = Rear Sprocket Teeth / Front Sprocket Teeth = 45 / 15 = 3.00
