Timing Pulley Pitch Diameter Calculator
Here’s an example of a table outlining different standard pitch diameters for various timing pulleys:
| Pitch (mm) | Number of Teeth | Pitch Diameter (mm) | Pulley Type | Tooth Profile |
|---|---|---|---|---|
| 2.00 | 10 | 20.00 | GT2 | Trapezoidal |
| 2.00 | 20 | 40.00 | GT2 | Trapezoidal |
| 2.00 | 30 | 60.00 | GT2 | Trapezoidal |
| 5.00 | 10 | 50.00 | T5 | Trapezoidal |
| 5.00 | 20 | 100.00 | T5 | Trapezoidal |
| 5.00 | 30 | 150.00 | T5 | Trapezoidal |
| 10.00 | 10 | 100.00 | T10 | Trapezoidal |
| 10.00 | 20 | 200.00 | T10 | Trapezoidal |
| 10.00 | 30 | 300.00 | T10 | Trapezoidal |
| 3.00 | 10 | 30.00 | GT3 | Trapezoidal |
| 3.00 | 20 | 60.00 | GT3 | Trapezoidal |
| 3.00 | 30 | 90.00 | GT3 | Trapezoidal |
Key Terms:
- Pitch (mm): The distance between two adjacent teeth in the pulley or belt, measured in millimeters.
- Number of Teeth: The total number of teeth present on the pulley.
- Pitch Diameter (mm): The diameter of the pulley measured at the pitch line where the teeth mesh with the belt.
- Pulley Type: Specifies the timing pulley standard, such as GT2, T5, T10, GT3, etc.
- Tooth Profile: The shape of the teeth of the pulley (often trapezoidal for timing pulleys).
