As a core component of precision transmission, RV reducers are widely used in industrial robots, machine tool rotary tables, automated equipment, and other fields. They are highly regarded for their high precision, high rigidity, and high load capacity. However, for many companies using RV reducers for the first time, selecting the right model from numerous options and parameters often poses a significant challenge. This article will startThey are highly regarded for their high precision, high rigidity, and high load capacity. However, for many companies using RV reducers for the first time, selecting the right model from numerous options and parameters often poses a significant challenge. This article will start with the basic principles of RV reducers, delve into their current status and key parameters, and explain the selection steps in detail, enabling you to easily master the essentials of RV reducer selection. Both beginners and experienced engineers can benefit from this guide.

Humanoid robots are evolving from demonstrating capabilities in laboratories to wide-ranging industrial applications. A productivity revolution driven by lightweight materials, embodied intelligence and autonomous battery replacement technology is taking place in factories, hospitals and homes worldwide. The "joint revolution" of humanoid robots is underway. A humanoid robot consists of thousands of components, among which actuators, as the most critical moving parts, are called the robot's "joints and muscles." Harmonic reducers are widely used in rotary joints due to their high precision and compact size.

The RV reducer gearbox is developed on the basis of traditional cycloid planetary transmission. Its reduction structure consists of the first-stage planetary reducer and the second-stage cycloid pinwheel reducer. It uses at least two eccentric shafts to connect the secondary reduction mechanism. The housing and cycloid pinwheel are matched and driven by solid castings and steel components, which form a closed differential gear train. The RV reducer gearbox not only overcomes the shortcomings of general cycloid pinwheel transmission but also has a series of advantages such as high precision (backlash less than 1 arc minute), high rigidity, high durability, high output density (high torque and compact), wide reduction ratio range, and low vibration.

With advancements in AI, IoT, big data, sensors, and BIM technologies, the construction industry is transitioning from traditional manual/semi-automated methods toward full automation, intelligence, and data-driven operations. Intelligent construction has now become the dominant trend, where construction robots significantly accelerate project timelines and are essential for industry-wide quality enhancement. As critical components ensuring robotic precision and stability, harmonic drives, RV reducers, and planetary gearboxes perform distinct roles across various robot subsystems.
