# machine element project for gear

1) Solve statics problem to determine applied loads on all components based on requirements\r\n- bearings, driveshaft, gears, ...\r\n2) Try using a pillow block by for the bearing supports. The pillow block couples out driveshaft\r\nbending into equal and opposite transverse shears, so the rolling element bearings do not see\r\nany moment loads. Or you could also size several journal bearing supports to see the difference\r\nin complexity and weight.\r\n3) Determine loading diagrams - shears, moments, torsion, axial loads versus location along\r\ndriveshaft and at bearing & gear locations.\r\n4) Use appropriate stress theory to translate applied loads into a stress state at critical locations\r\n5) Use Mohrs circle equations to determine maximum principal and shear stresses\r\n6) Guess a material to use and size the components - pick bearings and gears from a catalog\r\nbased on static loads and fatigue life requirements\r\n7) Use DET - Von-Mesis, or other static failure theory, to determine static margins of safety at\r\ncritical locations using some factor of safety relative to yield strength\r\n8) Apply some empirical stress concentration factors based on manufacturing processes,\r\ngeometry, surface finishes, etc.\r\n9) Calculate fatigue life of the components for some fatigue life criteria\r\n10) If any components (gears, driveshaft, bearings, pillow blocks, etc.) do not meet criteria,\r\nthen resize and redo analysis\r\n11) Select an AC motor to drive the system.\r\n12) Perform detailed analysis of the spur and bevel gear tooth stress analysis - time permitting\r\n- if desired\r\n13) Optimize the design to reduce weight by taking out weight where not necessary - redo\r\nanalysis\r\n14) Perhaps estimate cost of system by gathering cost information on components selected\r\nfrom catalogs... or a trade-off analysis on cost versus weight...\r\n15) Perhaps do FEA analysis using computer software like ProE, time permitting, if desired.\r\n16) You could modify the design to include a motor, springs, or other mechanical elements if\r\ndesired.
