1 ME-430 Introduction to Computer Aided Design Ball Bearing 6201 Metric Pro/ENGINEER Wildfire 2.0 By: Dr. Herli Surjanhata In a system window, create a new directory called ME-430 (e.g. H:\ME-430). From File pull down menu, select Set Working Directory. Select Working Directory dialog box appears 2 Select the ME-430 directory to highlight it and select OK. All files created in this session will be stored in ME- 430 directory. Note: You can also create a new directory by selecting . Pick the Create a new object icon . 3 Type in ball_bearing for the name of the new part. Un-check Use default template. The default units of Pro/E is mmns_part_solid. Click OK since the part will have mm units. Click OK in the New dialog box. The default datum planes appear in the graphics area. 4 CREATE BEARING HOUSING USING REVOLVED PROTRUSION Create the base feature – Pick the Revolve Tool icon . In the dashboard, click . Click Define. Pick FRONT datum plane as Sketch Plane, accept default (Sketch Orientation Reference) and click the Sketch button . 5 Click the Close button in the References dialog box. Click the small forward > icon to expand, and pick . Draw two centerlines thru coordinate system. One horizontal centerline and the other vertical centerline. Be sure to draw the horizontal centerline first since it will be used as an axis of revolution. These centerlines are used to ensure symmetry of the section. Use , , and (Fillet Tool) to draw the section as shown below. Then use to dimension the section, and use to modify the dimensions so that the resulted section is shown below. Note that inner bore diameter 12 mm and outside diameter 32 mm of the bearing are diametrical dimensions. 6 Tools -> Relations The Relations editor appears. 7 Enter the following relation in the editor: Note that the above parameters in this tutorial might be different from what you have. Be sure to use the correct parameters in establishing the relation formula of your part. Click OK. 8 Draw TWO horizontal lines as shown, and dimension the distance between them to 5.25 mm. Draw a horizontal centerline through the center of the circle. This centerline will serve as line of symmetry for both horizontal lines just created. 9 Click to access the constraints dialog box. Click on for symmetry constraint. Pick the endpoints of both horizontal lines, then pick the centerlines. The two lines will then be symmetrical with respect to the horizontal centerline through the circle. Close the Constraints dialog box. 10 Click , and delete the unwanted entities of the section. Be sure to have the final section as shown below.
