The Broken Drill Project: Creating a Universal Gearbox

Introduction In 2008, a broken drill sparked a creative project that would result in the development of a universal gearbox. The project aimed to repurpose the drill by turning it into a useful component for various applications, such as wind turbines and hand crank generators. This article explores the journey of transforming a broken drill into a versatile gearbox, highlighting the key components and their functionalities.

The Broken Drill and the High Voltage Low RPM Brushless DC Motor The broken drill served as the foundation for the gearbox project. By replacing the drill's original components, a high voltage low RPM brushless DC motor was integrated into its body. This motor would be the driving force behind the gearbox, providing the power necessary for different applications.

Creating a Gear to Interface with the Motor To harness the motor's spinning motion, a custom gear was 3D printed to perfectly fit over the body of the motor. This gear allowed for the transmission of rotational energy from the motor to the gearbox. By attaching the gear to a cradle, the motor could now generate power when spun manually or through external sources like wind turbines.

Using a Gearbox for Increased Speed To achieve greater rotational speeds and torque, a gearbox was introduced into the system. The chosen gearbox design was a planetary gearbox. Planetary gears are simple yet effective, consisting of a sun gear, planet gears, and a ring gear. By stacking multiple planetary gears, the system could achieve different gear ratios, multiplying the overall speed or torque output.

Introducing the Planetary Gearbox The planetary gearbox design consisted of a sun gear integrated with a fixing plate, multiple planet gears arranged on a ring carrier, and a ring gear. The gears were 3D printed and made from plastic, ideal for the prototyping and testing stage of the project. Metal gears and bearings can be substituted for increased durability and efficiency in future iterations.

Building the Planetary Gearbox The planetary gears were stacked and secured in place using a bolt and nut mechanism. This allowed the gears to spin independently yet remain connected, providing a compact and functional gearbox design. The modular nature of the gearbox design enabled flexibility in terms of gear ratio selection. The more gears added to the stack, the higher the gear ratio and the greater the speed or torque multiplication.

Testing the Planetary Gearbox The prototype gearbox was put to the test to evaluate its performance. With various gear ratios available, the gearbox demonstrated both high speed and high torque capabilities. The planetary gearbox proved to be a promising addition to the broken drill project, offering a reliable power transmission system for multiple applications.

The Universal Nature of the Gearbox One of the key features of the gearbox design was its universal nature. Both sides of the gearbox could act as input or output, thanks to the large sun gear and the adapter gear. This flexibility allowed for diverse applications, as the gearbox could be used for various purposes like driving a winch or operating a different device using the output shaft.

Applications and Future Development The universal gearbox opens up a wide range of potential applications. It can be utilized in wind turbine systems, hand crank generators, or any system that requires a compact and versatile gearbox solution. With further development, such as strengthening the gears with metal components and improving overall efficiency, the universal gearbox could become a valuable addition to renewable energy projects and other industrial applications.
