The walking axis of a robot is a core component for power transmission and support. RV reducers provide extremely high rigidity, precision, and torque while maintaining a compact size and exceptional reliability, making them an ideal match for the demanding requirements of walking robot joints in terms of load capacity, impact resistance, and precision.

The article explains Nabtesco’s dominance in RV reducers due to its high precision and reliability, while noting that the industry has few suppliers because of extreme manufacturing difficulty. It also briefly mentions competitors like Sumitomo, Spinea, and HONPINE offering cost and delivery advantages.

This article will explain the key selection points, advantages and disadvantages, brands and suppliers, as well as the differences between RV reducer gearboxes and harmonic drives.

Precision reducer gearboxes are the core transmission components of five-axis rotary tables, which directly affect the machining accuracy, dynamic response, and load capacity of machine tools. RV reducer gearboxes and harmonic drive reducers respectively dominate in heavy-duty and precision transmission applications. The two are often used together to implement hybrid drive solutions for high-end CNC machine tools.
