Mechanical Design of an Gearbox for a Turboprop Airplane
A gearbox for a turbo propeller airplane engine was designed, the input values was the weight of the propeller, and an enter of power of 13,500 RPM of pure torsion.
The project had the objective of determine the geometrical characteristics of each gear as: circular pitch, gear ratio, addendum, pressure angle and determine the most proper materials for each one, a CAD design of all components, and then determine the safety factor, life and stress of each gear using AGMA norm and then verification using a static & dynamic simulation of the gears in ANSYS Mechanical.
Requirements:
- The shafts must support the torsion, combined stress of the gears and a weight of 1150 lb
- Determine the geometrical characteristics of the gears
- Perform all the calculations using AGMA norm
- Determine stress, safety factor, life in static & dynamic conditions
- Design all the components and create the drawing & CAD
- Determine the most suitable materials for each component
- Perform a Finite Element Analysis for static & dynamic condition for the gears and shaft using Ansys Mechanical to corroborate the final design
