1.5. Create Path and Segment

Create a Links toolkit Path object for each sprocket as shown below:

  1. Select the Model element in the Project tree.

  2. From the Motion ribbon, click Links Toolkit and select Path.

  3. Under Motion in the project tree, right-click the new Path object and rename it as Sprocket_Guide.

  4. In the Details panel, verify that the Scoping Method is set to Geometry Selection.

  5. Using the Body selection tool, select the Sprocket_Guide body and click Apply in the Geometry field.

  6. Under Definition, click in the Contact Regions field (where is says Tabular Data).

  7. Ensure that the Contact Regions list contains the Named Selection titled Sprocket_Guide_Surface and click Apply.

     

  8. Set the Coordinate System for the path to Sprocket_Guide_Transform.

  9. Set Direction to Clockwise and Radius to 30.5 mm.

  10. Set Treat as Sprocket to Yes.

    Verify that the Details panel for the completed Path appears as below.

     

  11. Repeat steps 1 to 10 above to create two additional Path objects for Sprocket1 and Sprocket2. These objects should both be defined with a Radius of 30.5 mm and with Direction set to Counterclockwise. The completed paths should appear as shown below.

     

     

    You have now defined a complete set of sprocket paths.

     

Now, create a Links toolkit Segment object for each chain link as described below:

  1. From the Motion ribbon, click Links Toolkit and select Segment.

  2. Under Motion in the project tree, right-click the new Segment object and rename it as Chain1.

  3. In the Details panel, verify that the Scoping Method is set to Geometry Selection.

  4. Using the Body selection tool, select the Chain1 body and click Apply in the Geometry field.

  5. Set the Geometry Reference Coordinate System to Chain1_GeometryReference.

  6. Set the segment geometry as follows:

    • Segment Length : 9.52 mm

    • Segment Height 1 : 6.275 mm

    • Segment Height 2 : 6.275 mm

  7. Click in the Contact Regions field and ensure that the dialog contains the Named Selection titled Chain1_Contact.

  8. In the Details panel, under Reference, ensure that Scoping Method is set to Geometry Selection.

  9. Under Reference, click in the Geometry field. Using the Face selection tool, select the first link pin and click Apply.

     

  10. In the Details panel, under Mobile, ensure that Scoping Method is set to Geometry Selection.

  11. Under Mobile, click in the Geometry field. Using the Face selection tool, select the second link pin and click Apply.

     

    The defined reference (red) and mobile (blue) geometries should now appear in the graphical display as shown below.

     

  12. Repeat steps 1 to 11 above to create another Segment object for Chain2, using the same dimensions as Chain1.

    The completed segments should appear as shown below.
