How to create Ball joint in an Assembly | NX2306 version

Overview

In this TechTip you will learn about how to create Ball joint in an Assembly using Nx2306 version. A Ball joint is similar to a Spherical joint in the Motion application and removes three degrees of freedom. You can rotate the constrained component about all three axes and will not be able to translate along any axis.

You can use the part file from the – Download or Open ball_joint_tripod_adapter.zip File. (Active Subscription is required)

Please follow the below steps to achieve the required result –

Creation of Ball joint constraint in an assembly.

Step 1

Open ball_joint_tripod_adapter\ball_joint_tripod_adapter_assembly.prt.

Step 2

Select Assemblies tab >Position group >Joints and Couplers > Ball to display the Ball dialog box.

Step 3

To specify the vector for constraining the axis on the first object, choose “Specify Vector” from the options in the “Geometry to Constrain > Axis on First Object” dropdown menu. Then, select a cylindrical face on the component called “ball_joint.“

Step 4

To select the “Specify Point” option in the “Geometry to Constrain > Axis on First Object” dropdown menu, click on “Point Dialog” to open the “Point” dialog box.

Set the drop-down at the top of the Point dialog to Arc/Ellipse/Sphere Center.

Pick the spherical face as shown to define its center as the point.

Step 5

Click OK to return to the Assembly Constraints dialog.

Step 6

To choose the “Specify Vector” option in the “Geometry to Constrain > Axis on Second Object” dropdown menu, you should select a cylindrical face on the component called “head.”

Note: The vector should point in the same direction as that you defined for the First Object. If it does not, click Reverse Direction.

Step 7

To select the “Specify Point” option in the “Geometry to Constrain > Axis on Second Object” dropdown menu, click on “Point Dialog” to open the “Point” dialog.

Set the drop-down at the top of the Point dialog to Arc/Ellipse/Sphere Center.

Pick the spherical face as shown to define its center as the point.

Step 8

Click OK to return to the Assembly Constraints dialog.

Step 9

Aligning the axes and points of the two components, Click OK to create Ball joint.

Step 10

Open the Assembly Navigator and observe that the Ball joint has been generated and can be found within the “Constraints” folder.

Step 11

Using Move Component, You can notice here only three degrees of freedom that is rotate the constrained component about all three axes.
