Belt and Chain Length Calculation Dialog Box (AutoCAD Mechanical Toolset)

Use the Belt and Chain Length Calculation dialog box to choose a chain, a pulley, or a sprocket from the library and to determine the setting in the drawing.

New Tangent Definition Between Sprocket/Pulley

Defines a new tangent definition. This option is activated when no tangent definition exists in the drawing.

Belt

Chooses a belt from the library.

Chain

Chooses a chain from the library.

Move Manual

Enables manual movement of the pitch circles.

Length Calculation

Calculates the length of the belt or chain polyline.

Auto. Optimization

Optimizes the belt or chain geometry. Options let you move pitch circles in different directions.

Sprocket/Pulley for Move/Rotation>>

Determines the pitch circles that are to be moved. If this option is not selected, the pitch circles that do not contain tangent information, or the one that was selected before are moved. In practical operation this is usually the chain adjuster or the belt tightener.

Move

Prescribes a movement along a straight line.

Direction for Move >>

Prescribes the direction of the movement. Select this option to redefine the predefined direction of movement.

Rotation

Determines a center point around which the movement takes place. Determines a rotational movement.

Center Point for Rotation >>

Redefines the center point of the rotational movement.

Required Length

Displays the required setting value for the length of belts or chains.

Required Number of Links

Displays the required number of links along the drawn polyline.
