Bearing and Bushing
Use this function to create a bearing or bushing entity. The selections you make on this dialog box affect what you see in the preview window on the right side of the dialog box.
Using the Function
-
Click Tools>Mechanical Elements>Bearing. The Bearings dialog box appears, as shown below. See Dialog Options below for a description of this dialog box. The selections you make on this dialog box affect what you see in the preview window on the right side of the dialog box.
-
Select the type of bearing or bushing by clicking the desired button near the top left of the dialog box.
-
Select the desired representation option.
-
Type the dimensions for the bearing or bushing.
Note: If you attempt to create invalid geometry (for example, a bearing with a bore diameter larger than the outer diameter), an error message appears.
-
For a bearing, specify the desired rolling elements. (This step does not apply to a bushing.)
-
Type the diameter of the ball roller or cylinder.
-
Type the number of elements.
-
For a ball bearing, select the number of rows. (This step only applies to a ball bearing.)
-
Click the Style tab and select the desired style for the bearing or bushing.
-
Click OK to place the feature.
NOTE: To create a 2D side profile, digitize the center of the bearing or bushing end and a point along the shaft or bearing axis. For a top profile, digitize a center location for the bearing or bushing. For side representations, after you pick the location for the center of bearing or bushing end, you are asked to choose the axis orientation for the bearing or bushing. If you press ENTER at this point, a dialog box appears allowing you to enter the angle into a text field. For a plain 3D or solid bearing or bushing, the digitizing position is located at the center of the bearing at its end. For a 3D, solid bearing or bushing with a flange, the digitizing position is located at the center of the flanged diameter. 3D and solid bearings or bushings are drawn in the –zv direction in the current construction plane.
