29.2.6. Crown Roller

The crown roller is a geometric entity created the roller with a complex shape. It is only used in the shell belt assembly. It is contacted to the plane of shell belt whether it is located the inside or the outside of belt assembly loop.

29.2.6.1. Modeling Options

The user can create a crown roller as follows.

• Point, Distance

  • Point: Selects a point to define the center of the crown roller.

  • Distance: Defines a distance of the crown roller.

• Point, Distance, Depth

  • Point: Selects a point to define the center of the crown roller.

  • Distance: Defines a distance of the crown roller.

  • Depth: Defines a depth of the crown roller.

29.2.6.2. Properties

Figure 29.37 Crown Roller property page [Characteristic page]

The Crown Roller property page is shown in Figure 29.37. The parameters are explained below. In order to understand the geometry, refer to Dimension Information.

• Radius (R): Enters the radius of crown roller. The radius is larger than 0.

• Width (W): Enters the width of crown roller. The width is larger than 0.

• Assembled Radius: Enters the assembled radius of crown roller. The radius is larger than 0.

• Profile

  • X,Y,R: Defines points and radius.

  • Add Row: Adds a row to the end of the table.

  • Insert Row: Inserts a row where the cursor is and move the current and later rows down.

  • Delete Row: Deletes the row where the cursor is and move the later rows up.

  • Clear: Deletes all rows in the table.

  • Draw: All data must be defined with respect to the center marker. You can move points graphically by using the mouse directly.

  • Import: Imports the X, Y, and R data pairs from a CSV file or a MAT file or a text file. In the case of the text file, the usage of the comma, the tab, and the space can be the delimiter between the three columns in the file. And when using the Excel file, the user can select the Tab-delimited text file output option or the CSV (Comma-Separated Values) file output option to save the Excel file which can be imported.

  • Export: Exports the X, Y, and R data pairs to a CSV file or a MAT file or a text file.

• Full Search: If this is checked, all belt bodies are searched for the contact with the roller.

• Partial Search: If this is checked, belt bodies within the given bounds are searched for the contact with the roller.

• User Boundary: Enters the range of boundary.

Note

If you want to make the Crown Roller concave, enter Y value greater than 0 and R value positive number.
