Lab Preview for Overhead Pulley Project. This project is an extension of the Pro-e “Getting Started” project we did in last week’s lab. By completing the overhead pulley that you made the bracket for last week, you will be introduced to new tools and features as well as the assembly process in Pro-E.

The Pulley Wheel: We used the extrude tool to create the bracket in the Getting Started project last week. Extrusion is a swept feature where the cross-section is swept along a linear path. This operation is similar to extrusion processes in manufacturing where ductile materials are pushed through a die whose shape is the cross-section of the finished product, or drawing, where the ductile material is pulled through a similar die. For any of you interested in woodworking, you may have worked with a moulder, where a rotary cutter with a shape defining the finished product ‘sweeps’ along a board. The revolve tool allows us to sweep about an axis.

To see how it works, open a new part in Pro-E named “pulley_wheel_xxx” in your MAE184 directory and create a sketch similar to that shown below. Use the Centerline icon and place centerlines on both the X and Y axes. Use the revolve tool and select the x axis as the axis of rota After accepting the revolve operation, you should obtain a disk similar to that shown here. When you finish, exit the sketch

With the bracket, we used the cut-extrude to remove material to make holes in the bracket. If we require a hole in the center of a revolved object, we can work the hole into the sketch. Right-click on the sketch and Rename it to PULLEY_PROFILE, then right- click and select Edit definition. Note that
