1. What is Gear Ratio?

The gear ratio is the ratio of the number of teeth on the driven gear to the number of teeth on the driver gear. It determines the mechanical advantage and speed relationship between two meshing gears.

2. How Does the Calculator Work?

The calculator uses the gear ratio formula:

Where:

• Driven Gear Teeth — Number of teeth on the driven (output) gear
• Driver Gear Teeth — Number of teeth on the driver (input) gear

Explanation: A ratio greater than 1 indicates speed reduction and torque multiplication, while a ratio less than 1 indicates speed increase and torque reduction.

3. Importance of Gear Ratio Calculation

Details: Proper gear ratio selection is crucial for achieving desired speed and torque in mechanical systems, from vehicles to industrial machinery.

4. Using the Calculator

Tips: Enter the number of teeth for both driven and driver gears. Both values must be positive integers (minimum 1 tooth).

5. Frequently Asked Questions (FAQ)

Q1: What does a 2:1 gear ratio mean?
A: It means the driven gear rotates once for every two rotations of the driver gear, providing speed reduction and torque multiplication.

Q2: How does gear ratio affect speed and torque?
A: Higher ratios reduce speed but increase torque, while lower ratios increase speed but reduce torque.

Q3: Can gear ratio be less than 1?
A: Yes, when the driven gear has fewer teeth than the driver gear, resulting in speed increase and torque reduction.

Q4: What's the difference between driven and driver gears?
A: The driver gear is connected to the power source, while the driven gear receives motion from the driver gear.

Q5: How do I calculate multiple gear stages?
A: Multiply the ratios of each stage. For example, two 2:1 stages give an overall ratio of 4:1.
