Dialog: Pulley


See Add Pulley

A Pulley is a wheel with teeth that engage with a toothed-belt. The belt wraps around the pulley.

The path of the belt is controlled with a sketch-loop

The motion of the belt is controlled with motion-values at the input-connector to a Motion-Path FB.

Use the Pulley dialog to edit the number-of-teeth on a Pulley.

Pulley Parameters 


The number-of-teeth around the circumference of the Pulley.

The Number-of-Teeth and Tooth-Pitch (see Motion-Path FB) control the P.C.D of the Pulley and the radius of the Arc in the sketch-path.

Pitch-Circle-Diameter (PCD) - read-only

The diameter of the Pitch-Circle, which is co-radial with the neutral line of the Belt.

Belt Parameters 

Tooth Pitch - read-only ( Edit with the Motion-Path dialog )

The linear distance between two adjacent teeth on the belt.

Belt Length - read-only

The total length of the belt. It is equal to the length of the sketch-loop that wraps around the Pulleys.  

The length of the Belt will change as you edit the Number-of-Teeth on a Pulley,

You can select a dimension that will control the Belt-Length with the Motion-Path dialog.

Sprocket Parameters (Apply with Transition-Curve)
