Apply a gear relationship

To place a new part into the assembly, drag a placement part from the Parts Library into the assembly workspace.

The system automatically opens the Assemble command and the associated Assemble command bar, and highlights the placement part. For more information, see Assemble parts (workflow).

A Gear relationship does not physically position the parts in the assembly. Before you create the gear relationship, the related parts must be positioned using other assembly relationships such as Mate, Align, and Axial Align.

After placing the other relationships required to position the parts, select the Gear option from the Relationship Types list on the Assemble command bar .

For more information, see Using the Gear command bar.

Select the Gear Type from the list to identify the type of relationship being defined. This action drives the remaining sequence of actions.

• Rotation-Rotation

• Rotation-Linear

• Linear-Linear

For detailed information about gear types, see About the Gear relationship.

Select the first part that is to be used to form the relationship.

• For a Rotation-Rotation definition, either of the rotating parts can be selected.

• For a Rotation-Linear definition, the rotating part must be selected.

• For a Linear-Linear definition, either of the linear movement parts can be selected.

This part is identified as the first part.

Select the element on the first part to form the relationship. For a rotational part, select the appropriate circular edge or axis. For a linear part, select the axis or linear edge.

Select the second part that is to be used to form the relationship. For a Rotation-Rotation type, select the second rotating part. For Rotation-Linear, the linear movement part must be selected. For a Linear-Linear, select the second linear movement part.

This part is identified as the second part.

Select the element on the second part to form the relationship. For a rotational movement select the appropriate circular edge or axis. For a linear movement select the axis or linear edge. Note the direction of movement to ensure that the second part relationship can be adjusted to conform to the identified movement.

If the identified direction of movement is not correct with respect to the default direction of movement of the first part, select the Flip option to switch the direction.

Do one of the following base on the gear type:

• If defining a Rotation-Rotation type relationship, use the list to identify how the movement is defined:

  • Ratio for a defined ratio of movement of the first rotational element to the second rotational element.

  • Teeth for the number of teeth in the first gear followed by the number of teeth on the second gear.

• If defining a Rotation-Linear type relationship, enter the number of revolutions in the first box followed by the resulting linear movement in the second box.

• If defining a Linear-Linear type relationship, enter the amount of linear movement in the first part followed by the resulting linear movement in the second field.

To complete the action, press OK.

The Assemble command bar remains open to apply the next relationship. To apply another relationship, continue with Creating additional relationships.

To close the Assemble command and the Assemble command bar, press the Esc key.

To create another Gear relationship between two parts, you can do either of the following:

• To create a relationship using the Assemble command bar, the Assemble command bar must be open. If not open, select the Assemble command (Home tab→Assemble group→Assemble). On the Assemble command bar, select the Gear icon from the Relationship Types list.

• To create a Gear relationship using the Gear command bar, the Gear command bar must be open. If not open, select the Gear command (Home tab→Assemble group→Gear ).

The actions that can be performed are the same for each option. However, after the Gear command bar is opened, only a Gear relationship can be applied. The relationship type cannot be changed. For more information, see Using the Gear command bar.

Select the relationship parts and features as described previously.

To complete the action, press OK.

To close the command and the command bar, press the Esc key.
