Gearbox Design
The main objective of the project was to design a 3D printed gearbox to be implemented into a radio controlled car. The goal of this gearbox was to manipulate the input torque given by the motor to a desired output torque and corresponding angular velocity. The primary challenges of this design where creating effective power transfer system within the physical boundaries of the car frame. Vigorous calculations and models were created to ensure the shafts, gears and housing could undergo and pass a stress analysis (Including AGMA bending stress, fatigue stress and tresca/von misses failure theory) to ensure that the final design could complete the tasks without structural failure.
A final design was concluded and 3D printed under a strict time constraint (minimizing print time and maximizing material effectiveness). The gear box functioned as intended and was able to effectively transfer energy from the motor to the wheels of the car. With the high gear ratio chosen we were able to quickly move the car through the racing track with an impressive time, finishing in 3rd place of 20.
