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
