1. Prepare a three-view (front, top, right side) complete Unit Assembly Drawing of the "Shaft Support" from the AutoCAD Tutorial. Incorporate the re-designed Base Plate. (See UBLEARNS for Base Plate drawing) Also prepare a "Bill of Material" of all the parts including any additions and revisions. Be sure to show a full sectional view as illustrated in the Tutorial.
2. To demonstrate your knowledge and use of reference material, add the following
Fasteners to the assembly. (Use schematic threads in sectional view)
A. Replace Part #4 with two ½" - 13 UNC x 1-1/2" long round head cap screws with regular hex nuts and flat washers. (Modify the Bearing to accept the Cap Screws.)
B. In four holes in the Base Plate add:
3/8"-24 UNF x1-3/4" long flat head machine screws with square nuts. (Modify the Base Plate to accept the flat head screws.)
3. Revise the parts to the following materials and indicate the change in a revision box. (Show proper hatch symbol for each part in the sectional view)
Base Plate - change to 304 stainless steel
Bearing - change to cast iron
Collar - change to brass
4. Using the Tables of Limits in the appendixes in the back of your text, calculate the upper and lower limit dimensions between the following parts and list the answers in the space provided below. Also indicate the page number from which you extracted this information. Show the math on the back of this sheet.
COLLAR RC 4 FIT BEARING RC4 FIT
Upper limit ________ Upper limit_______
Lower limit________ Lower limit_______
Page #____________
5. Provide "BLOCK" drawings of all the parts.
6. Using Pro/Engineer, create a Solid Model drawing of the Collar. No dimensions are necessary.
