Pulley Speed Formula:
| From: | To: |
Pulley speed calculation determines the rotational speed of a driven pulley based on the speed of the driving pulley and their respective diameters. This is essential in mechanical systems where power transmission through belts and pulleys is involved.
The calculator uses the pulley speed formula:
Where:
Explanation: The formula shows that the speed of the driven pulley is inversely proportional to its diameter relative to the driving pulley.
Details: Accurate pulley speed calculation is crucial for designing mechanical systems, ensuring proper gear ratios, maintaining optimal machine performance, and preventing equipment damage due to incorrect speed matching.
Tips: Enter the driving pulley speed in rpm, and both pulley diameters in meters. All values must be positive numbers greater than zero.
Q1: What units should I use for the diameters?
A: The calculator uses meters for diameter measurements, but any consistent unit can be used as long as both diameters are in the same units.
Q2: Does belt thickness affect the calculation?
A: For precise calculations, effective pulley diameter (including belt thickness) should be considered, though this calculator uses nominal diameters.
Q3: Can I use this for multiple pulley systems?
A: This calculator handles two-pulley systems. For multiple pulleys, calculations need to be done sequentially.
Q4: What if the pulleys have different units?
A: Ensure both diameters are in the same units before calculation. The calculator assumes consistent units.
Q5: Is belt slip considered in this calculation?
A: No, this calculation assumes ideal conditions without belt slip. Actual speeds may vary slightly due to slip.
