Belts - Pulley Diameters vs. Speed
Calculate pulley speeds and diameters for single and multiple belt transmission systems using pulley diameter and speed relationships.
Single Belt Transmission Calculator
For a system with two pulleys (1 and 2):
Formula: d₁ × n₁ = d₂ × n₂
Multiple Belt Transmission Calculator
For a system with four pulleys (1, 2, 3, 4):
Formula: n₄ = n₁ × (d₁ × d₃) / (d₂ × d₄)
