Belt drive

Two pulleys linked by a belt: they turn the same way.

How to add

In 3D mode: Mechanisms → Belt drive.

Properties

Ratio
Positive: the pulleys turn the same way.
R₁ and R₂
Pulley radii. Their ratio sets the transmission ratio.
Force
The maximum transmission force.

Tips

  • The pulley with the smaller radius turns faster.
  • A belt transmits motion over a distance; gears only when they touch.
