1- The gear forces shown act in planes parallel to the yz plane. The force on gear A is 300 lbf. Consider the bearings at O and B to be simple supports. For a static analysis and a factor of safety of 3.5, use distortion energy to determine the minimum safe diameter of the shaft. Consider the material to have a yield strength of 60 kpsi. If the gear c is fixed with the shaft using interference fitting, select the suitable fit. Gear A 24-in D. 20 in 16 in Gear C 10-in D. 20° 10 in Fc Steps to be followed: 1- Draw free-hand sketch to show the fixation methods of gears and bearings. Visit the SKF.com site for bearing information. 2- Do Loading analysis. 3- Design the interference joint between the gear C and the shaft. 4- Do stresses analysis on the critical cross-section. 5- Do stresses analysis on the critical point on the critical section 6- Apply the yielding criterion.
