Project #6: A gear reduction unit 30:1 is to be designed using two spur gears (select one from the table). The velocity ratio may be varied by an amount necessary to have whole tooth numbers. Input horsepower is 100 HP at 1000 rpm. Kind of Lond Min. N. The teeth are to 20 degree pressure angle with Npinion > 17 teeth. The service is to be continuous with infinite life. Use SolidWorks to produce an assembly drawing with parts list attached. Use an FEA analysis in SolidWORKS/Ansys to verify your hand calculations. Max Ctr. Rpm hp Dist., Pinion in. Design the following: a) Decide upon the gear/pinion material with heat treatment, pitch, and face width. b) Determine shaft sizes considering bending and torsion in the pair of shafts c) Determine roller bearing sizes and specifications to support shafts d) Let the shaft material be AISI 1020 CD e) Find the dimensions of hubs and webs for two gears f) Assume input and output power via flexible couplings Decide upon all details of housing enclosing gears h) Submit report at or before the due date.
