1. What is Timing Belt Pulley Ratio?

The Timing Belt Pulley Ratio determines the speed relationship between two pulleys in a belt drive system. It's calculated by dividing the number of teeth on the driver pulley by the number of teeth on the driven pulley.

2. How Does the Calculator Work?

The calculator uses the simple ratio equation:

Where:

• \( Pulley1\ Teeth \) — Number of teeth on the first pulley
• \( Pulley2\ Teeth \) — Number of teeth on the second pulley

Explanation: The ratio determines how many times the second pulley will rotate for each rotation of the first pulley.

3. Importance of Pulley Ratio

Details: The pulley ratio is crucial for determining speed reduction/increase and torque multiplication in mechanical systems. It affects the performance of machinery, vehicles, and industrial equipment.

4. Using the Calculator

Tips: Enter the number of teeth for both pulleys as whole numbers. The ratio will be calculated automatically when you submit the form.

5. Frequently Asked Questions (FAQ)

Q1: How does pulley ratio affect speed?
A: The driven pulley's speed equals the driver pulley's speed multiplied by the ratio. A ratio greater than 1 increases speed, while less than 1 reduces it.

Q2: What's the relationship between pulley ratio and torque?
A: Torque is inversely proportional to speed changes. When speed increases, torque decreases, and vice versa.

Q3: Can I use this for belt length calculation?
A: No, this only calculates the ratio. Belt length depends on pulley diameters and center distance.

Q4: What's a typical pulley ratio range?
A: Common ratios range from 1:10 to 10:1, but specific applications may require different ranges.

Q5: Does this work for all pulley types?
A: This calculator works for any toothed pulley system where tooth count determines the ratio, including timing belts and synchronous drives.
