28.17. - As a final step to finish the assembly we'll add a new type of mate called

"Gear." The Gear mate allows us to define a rotational ratio between two cylindrical

components, even if the two components don't have any type of contact or

alignment. Adding this mate will allow us to simulate a gear driving another gear.

While still in the "With Gear"

configuration, select the L Origin ~ Invert Selection

28.18. - Before adding the Gear mate, move the components to a non-interfering

position, as seen in the next image. Rotate the view to see the clearance between

the gears and move them to approximately this position. While this step is not

required for the gear mate to work, it makes the simulation look better.

28.19. -Select the "Mate" command, expand the "Mechanical Mates" group near

the bottom, and select the "Gear Mate." For this type of mate we can select a

cylindrical face, a round edge or an axis of the 'Offset Shaft Gear' and another from

either the 'Worm Gear Complete' or the 'Worm Gear Shaft' ; since both are

connected, moving one will move the other.

After making the selections, in the teeth/diameter of the 'Offset Shaft Gear'

enter a value of 1, and for the 'Worm Gear' or 'Worm Gear Shaft' enter a value of

22. This value is not the actual diameter, but the gear ratio at which one will rotate

with respect to the other. The "Reverse" option inverts the rotation of the gears if

needed. Click OK to add the mate and finish the command.
