The adoption of advanced measuring equipment, such as CMMs and optical inspection systems, during assembly is non-negotiable, ensuring that the critical backlash specification remains within the guaranteed range (often less than 1 arc-min for high-end models), validating the precision engineering inherent in these components.
Another crucial technological element involves noise and vibration reduction. As industrial environments trend towards collaborative human-robot workspaces, quieter operation becomes a critical design requirement. Techniques include optimizing the meshing pattern of the cycloidal gears, incorporating damping materials in the housing, and improving the smoothness of the internal rolling elements. Efficiency improvement, though secondary to accuracy and stiffness, is achieved through optimizing gear tooth contact and utilizing specialized low-viscosity synthetic oils.
