1. What is RPM Calculation?

The RPM (Revolutions Per Minute) calculation determines the output speed of a gear system based on the input speed and gear ratio. It's essential for understanding mechanical systems and power transmission.

2. How Does the Calculator Work?

The calculator uses the RPM equation:

Where:

• \( RPM_{In} \) — Input revolutions per minute
• \( Ratio \) — Gear ratio (input:output)

Explanation: The output RPM decreases proportionally with increasing gear ratio. A higher ratio means slower output speed but greater torque.

3. Importance of RPM Calculation

Details: Accurate RPM calculation is crucial for designing gear systems, selecting appropriate motors, and ensuring proper operation of mechanical equipment.

4. Using the Calculator

Tips: Enter input RPM (must be positive) and gear ratio (must be greater than 0). The calculator will compute the output RPM.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical gear ratio range?
A: Common ratios range from 1:1 to 100:1 or more, depending on the application. High ratios are used for significant speed reduction.

Q2: How does this relate to torque?
A: While RPM decreases with higher ratios, torque increases proportionally (assuming 100% efficiency).

Q3: Can I use this for pulley systems?
A: Yes, the same principle applies to pulley and belt systems where the ratio is determined by pulley diameters.

Q4: What if my ratio is less than 1?
A: Ratios < 1 indicate speed increase (output RPM > input RPM) with corresponding torque reduction.

Q5: How accurate is this calculation?
A: This gives theoretical output RPM. Actual RPM may vary slightly due to efficiency losses in the system.
