A stepped transmission shaft is supported by the ball bearings at A and C where the shaft diameter is d. The shaft transmits a power 2HP at 1260 rpm to a gear that is mounted at B where the diameter is di and sheave that is mounted at D over diameter d3. The gear is meshed with another gear that is mounted on another shaft in XY plane parallel to the shown shaft. The force transmitted between the gears is at 20-degree angle (called pressure angle). The belt mounted on the sheave is perpendicular to the ZY plane. Design the transmission shaft for a minimum design safety factor of 2. Your design should include the steps described in the shaft design note. You should also consider the following recommendations: 1. Every single relation or equation used should be explained and be referenced. 2. The source of all the factors (stress concentration factors, etc.) should be stated. 3. Your approach to fatique and combined stresses should follow the general procedure outlined in the class. Critical stresses should be identified, shown on the elements modified by stress concentrations, combined by appropriate theory, and finally used in the applicable general fatigue theory formula. p=2.0- 1.5 snap ring key q=6.75 c=6.5 b=5 3.5 plane of F T gear shaft C bearing frame 1.5 -plane of F1 and F2 T sheave 1.5 gear not to scale sheave F
