The Transmission Ratio of Synchronous Belt Drive is defined as the ratio of the large to small pulley size and can be calculated by dividing the number of teeth in the large pulley by those in the small pulley.
The calculator uses the transmission ratio formula:
Where:
Explanation: The transmission ratio represents the speed reduction or multiplication between the driving and driven pulleys in a synchronous belt drive system.
Details: Accurate transmission ratio calculation is crucial for designing mechanical systems, determining speed relationships between components, and ensuring proper power transmission efficiency.
Tips: Enter the number of teeth on both the larger and smaller pulleys. Both values must be positive integers greater than zero.
Q1: What is a typical transmission ratio range for synchronous belt drives?
A: Typical ratios range from 1:1 to about 6:1, though specialized applications may use different ratios.
Q2: How does transmission ratio affect speed?
A: A higher ratio means the driven pulley rotates slower than the driving pulley, while a lower ratio means faster rotation.
Q3: Can this calculator be used for other types of belt drives?
A: While the principle is similar, different belt types may have specific considerations. This calculator is optimized for synchronous belt drives.
Q4: What if the pulleys have the same number of teeth?
A: If T₂ = T₁, the transmission ratio will be 1:1, meaning both pulleys rotate at the same speed.
Q5: How does transmission ratio affect torque?
A: The transmission ratio also affects torque multiplication - a higher ratio increases torque on the driven shaft while reducing speed.
