Single-Stage Gear Box
I worked as a member of a four person group regarding the design and analysis of a “Single-stage Gear Box ”. This report focuses on analyzing of all the different components of a gearbox using EES and solidworks. EES was used to do the loading analysis and equations on the shaft for both the gear and the pinion. This analysis was used to calculate the endurance limit for both the bending and torsion on the shaft, principle stresses, factor of safety, deflections, and the life limit. Using the given design requirements, we were able to calculated the necessary design specifications to choose the appropriate gear and pinion. We then used the solidworks parts to perform a design check and FEA simulations on the shaft and key way to determine the deflection and maximum stress. The results from this analysis lead us to use a ASTM A48 gray cast iron gear with 84 teeth and a 1020 Steel pinion with 16 teeth. With this specific gear and pinion we were able to have identical shafts with a 1.25in diameter, two bearings, and multiple snap rings.
