MIAE 313 - PROJECT
Design of a Power Transmission Drive
Design the power transmission drive shown in the Figure given the following information:
• The shaft is held by a radial ball bearing having an inside diameter of 1.000 inches, an outside
diameter of 2.000 inches, and a width of .500 inches located in the housing. Estimate sizes that are
not given. The end cap and a retaining ring hold the bearing in the housing. A single retaining ring
hold the bearing in position on the shaft.
• The end cap is held in the housing by a retaining ring.
• The gear is held to the clutch by a key and retaining ring. A key locked in position by a setscrew
holds the clutch in position on the shaft.
• The belt pulley assembly is held to the shaft by retaining rings and a square key.
• Dimensions shown are nominal sizes. Select proper fits for keys and bearings, using the tables in
the Appendix, showing the limits of size for each.
Redraw and dimension the power transmission drive after adding all the required parts and
determining any dimensions that are not given.
Hints: (1) You need to draw a cross section of the right side of the shaft where it holds the pulley,
and include the dimensions for the shaft. (2) You also need to include a parts list table.
