Timing Belt Ratio Formula:
| From: | To: |
The timing belt ratio is a dimensionless value that represents the relationship between the number of teeth on two pulleys in a timing belt system. It determines the speed relationship between the drive and driven pulleys.
The calculator uses the timing belt ratio formula:
Where:
Explanation: The ratio indicates how many times the driven pulley rotates for each rotation of the drive pulley.
Details: Proper timing belt ratio calculation is essential for designing mechanical systems with specific speed requirements, ensuring proper torque transmission, and maintaining synchronization between components.
Tips: Enter the number of teeth on both pulleys as whole numbers. Both values must be greater than zero.
Q1: What does a ratio greater than 1 indicate?
A: A ratio greater than 1 indicates speed reduction (the driven pulley rotates slower than the drive pulley).
Q2: What does a ratio less than 1 indicate?
A: A ratio less than 1 indicates speed increase (the driven pulley rotates faster than the drive pulley).
Q3: Can the ratio be exactly 1?
A: Yes, when both pulleys have the same number of teeth, the ratio is exactly 1, meaning both pulleys rotate at the same speed.
Q4: How does ratio affect torque transmission?
A: A higher ratio (greater than 1) increases torque at the output while reducing speed, while a lower ratio (less than 1) increases speed while reducing torque.
Q5: Are there limitations to this calculation?
A: This calculation assumes no belt slip and perfect engagement between belt teeth and pulley teeth. Actual performance may vary based on belt tension, wear, and other factors.
