1. What is Gear Reduction?

Gear reduction is the process of decreasing the output speed (RPM) while increasing torque through a gear system. This calculator helps determine the reduction ratio between input and output RPM for ATV applications.

2. How Does the Calculator Work?

The calculator uses the gear reduction formula:

Where:

• \( \text{Input RPM} \) — Engine or primary drive RPM
• \( \text{Output RPM} \) — Final drive RPM

Explanation: The ratio shows how many times the input speed is reduced to achieve the output speed.

3. Importance of Gear Reduction

Details: Proper gear reduction is crucial for ATV performance, allowing optimal torque delivery for different terrains and load conditions while protecting the engine from over-revving.

4. Using the Calculator

Tips: Enter input RPM (typically engine speed), output RPM (wheel or final drive speed), and select whether you want a listed (whole number) or custom (decimal) reduction ratio.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between listed and custom reduction?
A: Listed reductions are whole number ratios (2:1, 3:1 etc.) commonly available in gear sets, while custom reductions provide precise decimal ratios.

Q2: What are typical reduction ratios for ATVs?
A: Common ratios range from 2:1 to 6:1 depending on application, with higher ratios providing more torque but less speed.

Q3: How does reduction affect performance?
A: Higher reduction increases torque but reduces top speed, while lower reduction does the opposite.

Q4: Can I use this for other vehicles?
A: While designed for ATVs, the calculator works for any gear reduction calculation.

Q5: What about chain/sprocket reductions?
A: The same principles apply - just enter your input and output RPM values.
