Belt drive transmits power between shafts using flexible belt around pulleys. It's simple, quiet, and provides overload protection through slipping.

Fórmula

Calculate: Speed ratio = D_driven / D_driver where D is pulley diameter
D
D value — Variable used in the calculation

Guia passo a passo

  1. 1Calculate: Speed ratio = D_driven / D_driver where D is pulley diameter
  2. 2Torque: T = P / ω (power divided by angular velocity)
  3. 3Tension and slippage determine power capacity

Exemplos resolvidos

Entrada
Driver 100 mm diameter at 1800 rpm, driven 200 mm
Resultado
Output speed = 900 rpm, 2:1 reduction
Torque doubles

Erros comuns a evitar

  • Over-tensioning belts (damages bearings)
  • Neglecting wrap angle effects on friction

Perguntas frequentes

Why slip in belt drives?

Slight slip absorbs shock loads, protects driven equipment. Slip is normal (1-3%) and expected.

How do you prevent excessive slip?

Proper belt tension and friction material selection maintain power transmission.
