IMPELLER ASSEMBLY

PROJECT 2 IMPELLER ASSEMBLY MCEG 1021-P05 Mechanical Engineering Drawing I ABDULLAH SAFDAR STUDENT ID : P21019028 DUE ON NOVEMBER 25TH 2015 PROFESSOR : DR. BURRS STEPHANIE BREIF ELABORATION OF MECHAINCAL DESIGN AND ASSEMBLY This project for Impeller Assembly consists of 8 parts. 1. Top Housing 2. Bottom Housing 3. Impeller 4. Impeller Shaft 5. Bolt 6. Washer 7. Nut 8. Shaft Key Below is a step by step procedure of modeling each part and assembled them all together. TOP AND BOTTOM HOUSING DESIGN AND ANALYSIS I designed my bottom housing by sketching a curve in Sketch in Task Environment. Then I offsetted this curve to create a similar one. Next I extruded and revolved it 180 degrees to create a half circular shape My bottom housing was easy. I also had to rotate it 180 degrees on the x-axis.Then i saved this file and started working on current model to modify and make the top housing. . I created a box on top of my housing by placing a datum plane on top of it and then sketching out the box. I then extruded it onto my object and subtracted the block from the middle of the box to create the hole. IMPELLER DESIGN AND ANALYSIS I created my Impeller by first creating a cone with a base diameter of 15 and a top diameter of 8 and also a height of 16.25 inches. I then placed a datum plane directly in the middle of my cone to sketch my blade. I used combinations of arcs and line to make my blade. I then extruded my blade out and used the instance feature so I could I used circular array by 72 degrees. I then put a hole directly in the middle of my Impeller with a diameter of 1. BOLT DESIGN AND ANALYSIS I created my bolt by following the directions on ecourses. I created a cylinder with a diameter of .25 and a height of 1.5. I then placed a smaller cylinder on top of it and used the polygon feature again to place a hexagon on top of that by a distance of .1876 inches. I then used the thread feature to thread my cylinder to the right hand. Figure 4. NUT DESIGN AND ANALYSIS I c
