🔗 Belt Length Calculator
Calculate belt length, center distance, and pulley dimensions for various belt drive configurations
📐 Belt Length Formulas
L = 2C + π(D₁+D₂)/2 + (D₁-D₂)²/(4C)
C = (L - π(D₁+D₂)/2)/2 + √((L-π(D₁+D₂)/2)²/4 - (D₁-D₂)²/4)
L = 2C + π(D₁+D₂)/2 (Approximate)
C = (L - π(D₁+D₂)/2)/2 (Approximate)
L = belt length, C = center distance, D₁ = large pulley diameter, D₂ = small pulley diameter, π = pi (3.14159)

💡 Tips
- Use exact formula for precise calculations
- Consider belt stretch and tension
- Minimum center distance should be (D₁+D₂)/2
- Maximum center distance depends on belt type
- Account for belt thickness in calculations
- Consider pulley alignment and tensioning
