Tutorial : Creating Rack and Pinion Motion in CATIA

Here is how Rack and Pinion Mechanism can be created in CATIA

  1. Step 1:

    Open Create_Rack2.CATProduct document.

  2. Step 2:

    Click the Rack Joint icon in the Kinematics Joints toolbar or select Insert -> New Joint ->Rack... from the Menu bar.

  3. Step 3:

    Select Prismatic.2 in the specification tree.

  4. Step 4:

    Select Revolute.1 in the specification tree.

  5. Step 5:

    Assign a command, for instance select Angle driven for revolute check box.

  6. Step 6:

    Click Ok to end the rack joint creation.The rack joint is created and identified in the specification tree.
    Your mechanism can be simulated, a message is displayed.

  7. Step 7:

    Double-click Mechanism.1 to launch the simulation with commands functionality.

  8. Step 8:

    let's modify the ratio.
    Double-click Rack.3 in the specification tree

  9. Step 9:

    Click the Define button.
    The Rack Ratio Definition dialog box appears:

  10. Step 10:

    Select a circle in the geometry area. The ratio is automatically calculated.

  11. Step 11:

    The ratio is automatically calculated.

  12. Step 12:

    Click ok. Your Mechanism can be simulated.
