Gear Ratio Calculator
A gear ratio calculator is a very useful tool in the mechanical and engineering industry. Even the automotive industry is also taking benefits form this valuable online resource. With the help of this calculator, you can determine the force of rotation transferred between gears. Knowing this gear ratio lets you analyze other factors such as speed, torque, and overall system efficiency. Professionals in the mechanical engineering and the automotive industry can use our gear station calculator to optimize the gear terrains for desired performance outcomes.
Gear ratio calculation has various uses, such as designing the gearbox of a new vehicle, developing a mechanical system, or adjusting the gears in a piece of machinery. This article discusses the workings of this tool and also tells you how to use a gear ratio calculator.
How is Calculate Gear Ratio?
The calculatorology gear ration calculator is straightforward to use. It involves a few steps. To calculate the gear ratio using a gear ratio calculator, you need to input specific details about the gears in your system. Here’s how to use the calculator effectively:
- Identify the Number of Teeth on Gear 1: Determine the total number of teeth on the first gear in your gear train. This is usually referred to as Gear 1 or the driver gear. Then input this number in the first field.
- Identify the Number of Teeth on Gear 2: Determine the total number of teeth on the second gear, also known as Gear 2 or the driven gear. Enter the number in the second field.
- Input the Details into the Calculator: After entering the number of teeth on Gear 1 and Gear 2 into the respective fields of the gear ratio calculator, you have to enter the ‘calculate’ button to get your results.
Once the details are inputted, the calculator will process the information and provide you with the gear ratio, representing the relationship between the two gears.
Example
Suppose you are working on a mechanical system with two gears. Gear 1 has 20 teeth, and Gear 2 has 40 teeth. Now you want to know their accurate ratio. To do this, you need to open the calculatorology gear ration calculator. The interface is simple, input the =number of teeth in the respective field for gears one and two. The result you get from this calculation will be beneficial for understanding how these gears interact and affect the systems' performance.
Details
No. of teeth in Gear 1: 20
No. of teeth in Gear 2: 40
Solution
Step 01: Input the Number of Teeth on Gear 1:
Enter 20 in the field for Gear 1.
Step 02: Input the Number of Teeth on Gear 2:
Enter 40 in the field for Gear 2.
Calculate the Gear Ratio:
The gear ratio is calculated by dividing the number of teeth on Gear 2 by the number of teeth on Gear 1. Here is how it is calculated:
Formula
Gear ration = Number of Teeth on Gear 2Number of Teeth on Gear 1
Gear ration = 4020 = 2
The gear ratio for this system is 2. This means that Gear 2 will rotate at half the speed of Gear 1 but with twice the torque. This ratio is crucial for understanding how gear size changes will affect your system's mechanical performance.
How Gear Ratio Affect Speed?
Different gear ratios affect the rotational speed of the gears. For instance, if Gear 1 has 20 teeth and Gear 2 has 60 teeth, the gear ratio is 3.0, so if Gear 1 rotates at 100 RPM, Gear 2 will rotate at approximately 33.33 RPM.
Gear 1 Teeth | Gear 2 Teeth | Gear Ratio | Speed of Gear 1 (RPM) | Speed of Gear 2 (RPM) |
20 | 60 | 3 | 100 | 33.33 |
30 | 60 | 2 | 120 | 60 |
25 | 75 | 3 | 80 | 26.67 |
10 | 40 | 4 | 150 | 37.5 |
15 | 45 | 3 | 90 | 30 |
