Tutorial : Creating Gear Joints in CATIA


Here's the simple way to get Gear Joints

  1. Step 1:

    Click the Gear Joint icon in the Kinematics Joints toolbar or select Insert -> New Joint ->Gear... from the Menu bar.
    The Joint Creation: Gear dialog box appears.
    The Mechanism is identified in the specification tree.
    Now you need to select two Revolute joints.

  2. Step 2:

    Select Revolute.1 either in the specification tree or in the geometry area.

  3. Step 3:

    Create Revolute.2 within the Gear command. For this: click Create button
    The Joint Creation: Revolute dialog box appears automatically:

  4. Step 4:

    Select line .1 (Gear1 axis) and line.2 (Gear2 axis) as shown below in the geometry area:
    Select plane.1 (Gear1 face) and plane.2 (Gear2 face) either in the specification tree or in the
    geometry area:

  5. Step 5:

    Select the Offset option button and keep the default value. When done, click Ok.

  6. Step 6:

    Assign a command, select for instance the Angle driven for revolute1 check box.

  7. Step 7:

    Click "define" button to define the ratio parameter automatically. The Gear Ratio Definition dialog box is
    automatically displayed.

  8. Step 8:

    Select the two circles in the geometry area. each one for Gear 1 and Gear 2.

    The calculated ratio appears in the Joint Creation: Gear dialog box.

  9. Step 9:

    Change the rotation direction option if needed.
    The default is Same (positive)
    Opposite is negative

  10. Step 10:

    Click Ok when done
