$\backslash$tau $\_($max $)($S$\_(1))$ diameter $=1\mathrm{.}5$ in

The number of teeth on gear $1($G$\_(1)),$N$\_(1)=30$

The gear ratios G$\_(2)$:G$\_(1),$G$\_(3)$:G$\_(1),$G$\_(4)$:G$\_(1),$ and G$\_(5)$:G$\_(1)$ are $50$:$30,19$:$15,4$:$5,$ and $18$:$30$ respectively.

Torque generated by the motor T$\_(1)=4000$lb in

Force on the pulley F$\_($puliey $)=2000$N

Drive Pulley Radius $=6$ in

Assume gears transfer torque to shaft with no loss, and distance between gears is based on the

center of gear.

Tasks:

Torque Transmission Calculation:

Calculate the effective torque transmitted $($T$2,$ T$3,$ T$4,$ and T$5$ using the gear ratios$)$

for each gear combination $($G$1-$G$2,$ G$1-$G$3,$ G$1-$G$4,$ G$1-$G$5)$

Verify that each gear combination transmits sufficient torque to drive the pulley.

Adjust any gear ratio that does not transmit the adequate torque.

Shaft Diameter Optimization:

Assume initial diameters of the shaft S$\_(2)$S$\_(2-1,)$S$\_(2-2),$S$\_(2*3),$S$\_(2-4)$ S$\_(2)$

Gears $2-5$

Flange Coupling Bolts for the coupling on shaft S$\_(1)$

Keys for gears $2-5$

Animation and Rendering $($Extra Credit$)$:

Animate the assembly and provide appropriate rendering for visual clarity.

Deliverables:

Design Calculations: Hand calculations for all design components $($torque$,$ stress, angle of

twist, etc.$)$

Optimization Files: Excel file including your formulae and the optimization curves and the

MATLAB file $(.$m file$)$ that runs and plots the optimization curves.

CAD Model Files:

$.$ SLDASM file of the final assembly $($if you use the pack$-$and$-$go feature in Solidworks,

it will create a zip file that includes your assembly as well the individual parts$)$

$.$SLDPRT files of the individual components

Exploded view of the assembly if possible

$.$SLDDRW files showing front, side, top, and isometric views with dimensions.

FEA:

Description of the procedure followed, including boundary conditions, mesh

generation, selection of failure theories, etc.

Screenshots showing results obtained $($Equivalent stress, total deformation, FOS,

etc.$)$

All work MUST have careful and detailed Annotations, Intepretations and Demonstrate

understanding of each of the above items. Work without annotation will results in

deductions of points. The deduction will be subject to the discretion of the instructor.
