V-Belt Length Calculator
Here's a comprehensive table summarizing all you need to know about V-Belt Length:
| Aspect | Details |
|---|---|
| Measurement Types | - Li: Inner length (internal length) - Ld/Lw: Date length (cord length, ISO standard) - La: External length2 |
| Standard V-Belt Designations | A, B, C, D, E, Z3 |
| Narrow V-Belt Designations | 3V, 5V, 8V3 |
| Fractional Horsepower V-Belt Designations | 2L, 3L, 4L, 5L3 |
| Calculation Formula | L = π(R+r) + 2a + (R-r)²/4a Where: L = belt length R = radius of larger pulley r = radius of smaller pulley a = distance between pulley centers1 |
| Length Conversions (Classic Profiles) | - Date length = Inside length + 30 mm - Outside length = Inside length + 50 mm2 |
| Length Conversions (Narrow Profiles) | - Inside length = Date length - 45 mm - Outside length = Date length + 18 mm2 |
| Measurement Method | Measure across the top width and the depth of the belt4 |
| Measurement Tools | V-belt length gauge (e.g., VB900000) for easy measurement2 |
| Identification Tips | - Check for number indicated on the belt - If illegible, measure the effective belt length - Consult a specialist or product expert if unsure24 |
This table provides a comprehensive overview of V-Belt length information, including different measurement types, designations, calculation formulas, length conversions, and measurement methods. It should serve as a quick reference guide for all essential aspects of V-Belt length determination and identification
