Screwdriver

This project was part of the Machine Drives and Mechatronics module, where we were tasked with designing and constructing a low-power electric screwdriver using a gear mechanism to achieve specific speeds. As a team, we opted for a planetary gear system due to its compactness and efficiency. The process involved creating CAD models, performing theoretical calculations to ensure safety and functionality, and 3D printing components for the prototype. The final product successfully met the module requirements, operating within the specified speed range and demonstrating effective functionality.

CAD Models of the Gear System:

• An exploded view of the planetary gear design, illustrating individual components and their assembly. 

CAD Models of the Internal and External Design:

• Close-up of the internal arrangement showing how the planetary gears mesh with the ring gear. 

• A CAD visualization of the outer casing, designed to house the planetary gear system, motor, and other components. 

Manufacturing Process:

• The 3D-printed gear parts, ready for assembly into the prototype. 

• Images showing the electrical connections, including the 3V DC motor, DPDT switch, and battery connections.

• The manufactured version of the screwdriver, featuring all components, including the motor, planetary gear system, and protective casing, securely assembled. 

Final Product:

• The completed screwdriver prototype, featuring a compact cylindrical design for ease of use.

• The screwdriver in action, successfully screwing in and out as per the project specifications.
