30.2.3. Multiplex Sprocket
The chain converts rotational power to pulling power, or pulling power to rotational power, by engaging with the sprocket. In general, a chain system employs single sprocket consisted of teeth and the main body named sprocket hub. Exact sprocket tooth geometry must be defined. The sprocket tooth geometry data can be created, edited, exported or imported from a predefined data file.

30.2.3.1. Modeling Options
The user can create a sprocket as follows.
Point, WithDialog
Point: Selects a point to define the center of the sprocket.
WithDialog: Modifies the property for the sprocket. The sprocket is created with clicking OK.
30.2.3.2. Properties
Figure 30.27 Multiplex Sprocket property page [Geometry Data page]
The Multiplex Sprocket property page is shown in Figure 30.27. The parameters are explained below. In order to understand the geometry, refer to Dimension Information.
Number of Stands: Defines the number of sprockets.
Transverse Pitch (Pt): Defines the distance between Sprockets.

Contact between a Multiplex Sprocket and a Multiplex Link
The sprocket is in contacts with the chain link in the two parts.
The sprocket teeth surface – the roller of chain link
The sprocket teeth surface - the inner plate surface of chain link
