The requirements for this design project are as follows: a) Calculate the output power. b) Calculate the gear reduction ratio. c) Calculate the total efficiency of the gearbox. d) Select, calculate, determine all the gear parameters, module, pitch, number of teeth, diameters, width, pressure angle etc. for all the gears in all the stages. e) Provide the technical drawings of these gears. f) Determine the minimum shaft diameters of all the stages. g) Calculate the reaction forces in the shafts, draw the shear force and bending moment and torque diagrams. Draw the free body diagrams of each stages. h) Design the shafts including all the details, shoulders, grooves, keyways etc. must be shown in the provided technical drawings. Check the critical sections in the shafts by applying stress analysis. i) j) Determine the type and dimensions of the bearings used in each stages. k) Design the keys, provide the material, type, width, height and length of them. 1) Draw the assembly drawing of the gearbox having the correct dimensions found in the design steps. Provide section views in the assembly drawing. m) Specify all the assumptions, approaches etc. you used in the design steps. Do not forget to add a list of references, if necessary.
