Design and Construction
The Hex Brass Coupling is manufactured from brass to provide a reliable and durable mechanical connection for compatible robot wheel assemblies. Its compact hexagonal design allows it to integrate easily with compatible wheels and shafts while maintaining a lightweight form factor.
The 8.1mm bore diameter is designed for compatible shafts, while the 12mm edge width provides a suitable mechanical interface for the corresponding wheel assembly. The 18.05mm total length keeps the coupling compact for use in various robotic mechanisms.
With an approximate weight of only 9g, the coupling is suitable for mobile robots where maintaining a lightweight mechanical structure is important.
Compatible Product
The Hex Brass Coupling is designed for use with our:
130mm Robot Wheel for All Terrain and DIY Robotics
Please verify the shaft diameter, wheel interface, and mounting dimensions before installation to ensure proper compatibility.
Working Principle
The Hex Brass Coupling acts as a mechanical connection between a compatible motor or drive shaft and the robot wheel. The shaft is inserted into the 8.1mm bore, while the hexagonal outer profile interfaces with the compatible wheel.
When the motor rotates the shaft, the coupling transfers the rotational motion to the wheel, allowing the robot to move. The brass construction provides a rigid mechanical connection during normal operation.
The coupling is a passive mechanical component and does not require electrical power.
