Pololu 71 Tamiya 72002 High-Speed Gearbox Kit
The Pololu 71 Tamiya 72002 High-Speed Gearbox Kit is a precision-engineered motor gearbox assembly designed for robotic platforms, wheeled vehicles, and autonomous systems requiring high-speed rotational output with compact form factor. Roboticists, hobbyists, and educational institutions utilize this gearbox to achieve rapid wheel speeds and agile movement in mobile robot projects. This kit solves the critical engineering challenge of converting standard DC motor torque into high-velocity output while maintaining mechanical efficiency and reliability in demanding applications.
Product Overview
The Tamiya 72002 High-Speed Gearbox Kit represents a refined approach to motor speed multiplication through a multi-stage gear train architecture. This gearbox employs hardened plastic and metal gears arranged in a sequential reduction pattern that amplifies motor shaft rotational velocity while distributing mechanical stress across multiple engagement points. The design incorporates precision-molded gear teeth with optimized pitch and pressure angles, ensuring smooth power transmission with minimal backlash and vibration. The compact cylindrical housing allows seamless integration into standard Tamiya chassis platforms and custom robot frames, making it ideal for applications where space constraints demand efficient mechanical solutions.
The high-speed variant of this gearbox delivers output speeds typically ranging from 150 to 300 RPM depending on motor specifications and load conditions. The gear ratio optimization prioritizes velocity over torque multiplication, making it particularly suitable for racing robots, fast-moving surveillance platforms, and applications requiring rapid repositioning. The modular design allows users to couple multiple gearbox units for differential drive systems, and the standardized shaft interfaces ensure compatibility with wheels, pulleys, and encoder attachments commonly used in robotics projects.

How to Use
Assembly of the Pololu 71 Tamiya 72002 High-Speed Gearbox Kit requires careful attention to gear alignment and proper fastener torque specifications. Begin by organizing all components including the motor shaft coupler, gear stack, housing plates, and fastening hardware. Insert the motor shaft into the input coupling mechanism, ensuring the set screw engages the motor shaft flat or keyway without cross-threading. Progressively stack the gear assemblies into the housing, verifying that each gear meshes smoothly with its adjacent stage without binding or excessive play. Apply thread-locking compound to fastener threads before final assembly to prevent vibration-induced loosening during extended operation. Mount the completed gearbox assembly to your chassis using the provided mounting bosses, ensuring the output shaft rotates freely and the housing remains rigidly secured against the frame structure.
For optimal performance, couple the gearbox output shaft to your wheel or load mechanism using a flexible coupling or direct press-fit adapter appropriate to your wheel bore diameter. If implementing differential drive with two gearbox units, verify that both motors receive identical voltage and current to achieve synchronized wheel speeds. Test the gearbox under no-load conditions first, listening for unusual grinding sounds or mechanical resistance that might indicate misalignment. Once validated, gradually apply operational load while monitoring motor current draw to ensure the gearbox operates within its rated torque specifications. Perform periodic maintenance by inspecting gear engagement surfaces for wear patterns and verifying that all fasteners remain tight after extended use cycles.
Frequently Asked Questions
What is the typical output speed of the Tamiya 72002 High-Speed Gearbox?
The output speed depends on the input motor specifications and voltage applied. With standard Tamiya DC motors operating at nominal voltage, the high-speed gearbox typically delivers 150 to 300 RPM at the output shaft. The exact speed is determined by the motor's RPM rating and the gearbox gear ratio. For precise speed calculations, multiply your motor's free-running RPM by the gearbox reduction ratio. Higher motor voltages and lower load conditions will produce speeds at the upper end of this range.
Can I use this gearbox with different motor types or custom motors?
Yes, the Tamiya 72002 gearbox accepts any motor with a compatible shaft diameter and length that can be secured to the input coupling mechanism. Standard Tamiya motors, coreless DC motors, and many hobby-grade DC motors work effectively with this gearbox. However, verify that your motor's shaft dimensions match the coupling bore diameter, typically 3mm or 4mm depending on the specific kit variant. For custom motors with non-standard shafts, you may need to fabricate an adapter coupling or modify the input coupling bore using appropriate machining tools.
How do I reduce backlash for precision robotic applications?
The Tamiya 72002 is designed with minimal backlash in its gear train, but further reduction is possible through careful assembly technique and component selection. Ensure all gears are properly seated in their bearing surfaces without excessive play. Consider upgrading to metal gear alternatives if available for your specific gearbox variant, as metal gears typically exhibit less backlash than plastic gears. Use high-quality motor shaft couplings with minimal runout, and verify that the motor shaft is perfectly aligned with the gearbox input axis. For applications requiring absolute minimal backlash, consider adding a backlash-compensating coupler or implementing closed-loop encoder feedback for position correction.
Is this gearbox suitable for outdoor and wet environments?
The Tamiya 72002 features sealed bearing assemblies that provide basic environmental protection, making it suitable for light moisture exposure and dusty conditions typical of outdoor robotics competitions. However, the plastic housing and exposed fasteners are not fully waterproof. For extended outdoor use in wet conditions, consider applying waterproof grease to bearing surfaces, using stainless steel fasteners to prevent corrosion, and applying a protective coating to the housing exterior. For fully submersible applications, you would need to implement additional waterproofing measures or select specialized marine-grade gearbox alternatives.
