In this tutorial you will design a universal hub which attaches to the geared motor. The tutorial is intentionally open ended to encourage critical thinking.  Engineering Drawing:  Study this drawing carefully, you will need it to determine the dimensions of your part. Step 1: Draw the Basic Shape Start by drawing the hubs basic shape. Refer to the engineering drawing for dimensions.  Step 2: Cutout the Double D shaft In order to attach anything to the geared motor, you must attach it do a "Double D Shaft". Note: This step is complicated because Inventor deletes diameter constraints when you trim them.  Step 3: Cut all the Holes Cut all five holes on the hub. Refer to the engineering drawing for dimensions, and also https://sites.google.com/a/eng.ucsd.edu/mae3/cad-templates for the actual bolt hole dimensions.  Step 4: Done! You have completed the hub tutorial! This hub can be used as-is or modified. It is useful for attaching things such as linkages, gears, and pulleys to the geared motor.  |
