Mini Gearbox for Robotics

The mini gearbox for robotics motion is a compact, high-efficiency mechanical assembly designed to enhance the torque and control of robotic systems. Built to change the direction of drive shaft motion and accommodate small motors, this gearbox features an input shaft, precision gears, and an output shaft at angle 90° enclosed in a compact housing. The design allows for customizable gear ratios, enabling precise control over speed and torque for various applications, such as robotic arms, wheeled robots, and small actuators.

Made with lightweight yet durable materials like PLA, PETG as the 3D filament for printing the gear, shaft and housing. The gearbox ensures reliable performance. Bearings and bushings are incorporated to minimize friction and optimize smooth rotation, while its modular design supports easy assembly and integration into robotics projects.

Ideal for educational and mini robotics projects, this gearbox offers an efficient and scalable solution for motion control in compact spaces.

The drivegear is the primary gear in this mechanical assembly responsible for transmitting power from the motor or input source to the rest of the system. It meshes with one or more driven gears to transfer torque and speed, playing a crucial role in the performance and efficiency of this gearbox or an applied drivetrain.

The components to make this gearbox are

1. Drive gear
2. Driven gear
3. Gear washer
4. Drive shaft
5. Driven Shaft
6. Gearbox housing

Step 1.

Place the shaft washer in the gearbox housing side1 as a shown in the image.

The driven gear is a mechanical component that receives power and motion from the drive gear shown above. It is part of a gear box and plays a critical role in modifying the speed, torque and direction of motion. Driven gears are used to achieve desired output characteristics, such as reduced speed or increased torque, in various applications like robotics, machinery, and automated devices.

Step 1

Place the driven gear in the housing, making it go through the shaft washer as shown in the image

The drive gear is the primary gear in the gearbox assembly responsible for transmitting power from the motor or input source to the rest of the system. It meshes with the driven gear to transfer torque and speed, playing a crucial role in the performance and efficiency of a gearbox or drivetrain.

Place the Drive gear in the gearbox housing/casing making sure it meshes with the driven gear

Place the Outer housing carefully on the assembled gearbox. make sure the both gear-shaft of drive-gear and driven--gear are well aligned.

Secure the gearbox casing with m3 nut on both side.

Insert both drive and driven shaft.

Last step is to install on a robot just as shown above.
